Has anyone else noticed that when the tablet is charging, if you rub your fingers very lightly on the metal back you will feel what seems like very light vibrations? I tried this on two primes and each does the same----this only happens when the AC is plugged into the prime. It's as if the tablet is not properly grounded or something. I really want to like this thing but I have growing doubts about Asus' build quality.
For example, lightly rub the back left side from bottom to top. Keep your right off the tablet. Once you feel the tingling grasp the tablet with your hand (touching the metal of course). You should now notice the tingling can't be replicated with your left hand... As if your right hand is now grounding the tablet. Remove your right hand and continue rubbing with your left hand. Good vibrations??
Yeah I was wondering what that was

Thats just the prime sapping your life force, please disregard.
how do you guys find all these things? Y'all have too much time on your hand's!

Can't replicate the issue or maybe just don't realize it but nothing to worry about I'm sure
This was a problem with the original transformer too
Flipping the charger upside-down fixed the problem for the original
Try that?
Shouldn't be anything to worry about though, it happens with a lot of laptops too
http://google.com/search?q=tingly+sensation+when+charging
I don't have mine yet, but I'd put a multimeter on it.
Is this when you're charging via the 120v USB adapter or a micro-USB cable? If it's via the 120v adapter you don't have a ground at the outlet.
USB has a ground wire but if the adapter doesn't have a ground, then the ground in the TP is only going to be a floating ground. Now I'm not an electrician, but my understanding is that this kind of ground tends to feed back into the power source, or in this case, the battery. The lid is likely grounded to this circuit, meaning if you walk across a thick carpet and touch the lid of your Transformer, instead of possibly frying your Transformer, the electricity is thrown off into the battery / charging circuit.
If someone can provide a more educated answer it would be appreciated, but this appears to be by design... better to protect the electronics in the device than worry about a couple volts escaping the charging circuit onto the back of the device. It seems to me like there would be a diode somewhere to only let power flow from the back into the charging circuit instead of allowing the opposite... but perhaps someone can explain this.
EDIT - I think I figured it out. There probably is a diode between the chassis ground and the charging circuit so that voltage to the chassis will ground to the battery instead of the battery pushing voltage to the chassis, but when the battery is being charged and thus already has all the voltage flowing in that it can handle, the rest of the device has to ground somewhere since the 120v adapter does not allow for an earth ground. So the TFP's circuits are grounding to the chassis during charging for lack of anywhere else to ground to.
I'm willing to bet that using a micro-USB charging cable would solve this issue since the TFP could ground back to the PC at the other end via the USB ground wire instead of the chassis.
You must really love your prime if you were gently stroking its back while it charged...lol...that said, mine does it too.

Solution found - just do this!
Got some rubber Gloves?
Seriously, this is EXACTLY the same issue as we all experienced with the TF101. It is a polarity/grounding issue with the horrendously cheap charging unit supplied with the Transformer. A simple reversal of the polarity on the charger will stop the issue.
With the TF101, they released 2 different "fixed" charging... transformers, pun intended, and neither one made the slightest difference. I was seriously freaked when I first felt the "buzz" from the metal areas of the TF101, and did a LOT of research on it.
The weird thing is, they could have made one blade wider on the step down charger, to force it one way in the wall socket, but my guess it, it's different in different areas: Meaning, I had to put my charger in "upside down" (with the ASUS logo being upside down to eliminate the tingle, but at least one other person needed it the reverse.
It is seriously creepy feeling (some claim to like it LOL) and I can NOT believe that having a trickle of current, no matter how tiny, running across the entire casing can be good for the longevity of the device. When I saw that the charger was essentially unchanged form the TF101, I was seriously worried that the issue would still occur, and, of course with a full metal jacket, it would be that much more bothersome.
I do NOT expect ASUS to resolve this, since they never did on the first transformer, so it, just get used to plugging in the right way each time.
Anyone want to volunteer touch the casein when the buzz is present while in a bathtub? Might make for an interesting lawsuit.
I am actually semi-serious. Years ago we had a cheap Taiwanese video card fry the GPU, set off smoke alarms and bring out the Fire Department in the middle of the night. When I returned it the bottom of the pricing food chain warehouse, ALL of the employees came to the counter (all 12 of them, LOL) and wanted a look at it. You could see the noticeable worry on their faces, and what appeared to be actual fear in their eyes. Somewhat intrigued, I asked: "So why are you guys so worried about this? Answer: "We have a few hundred of these sold, and one in OUR labs fried last night, and actually started a fire. We are concerned about the others that are out there now...."
I'll BET they were. Asus isn't going to set anything afire, short of some tempers, but this is NOT a good issue to see an a "Premium" Top Tier Tablet. On THIS issue, I will be communication with ASUS.
Has anyone taken a multimeter and measured this? Touch one probe to the back of the Transformer Prime, and the other to a grounded or large metal object - a sink faucet or metal handrail etc..

It's the same with the original Transformer, never had any problem whatsoever with that. don't worry it won't eat you, burns your house or erase your HDD (though, I wouldn't try this one if i were you.)
If you want to worry about something related, worry about the AC charger, if it's the same as the original one it definitly looks like a fire hazard.
My aluminium HP laptop also has this. Same for my Desire Z. Nothing to worry about; move along people!
Testing testing...
I intent to take a multimeter to it, as soon as I GET that darned ting, and right after I test for light bleed, Wifi performance wne whetheI am one of the "lucky" one who's GPS actually functions.
MAN, am I glad I got the "Premium" experience of the Transfomer Prime.

Let me say I have experience in this
I have been doing Underwater photography for 25 + years and housing do leak.... and when they do, your Nikon or Video camera is about to be toast....... in short I have had many many episodes of salt water intrusion. Even the least amount will destroy lens coating or cause a micro short on a board or switch ruining a 1000.00 camera or lens.
Here is The Gist of how to fix a salt water episode:
1. if you got salt water on something, Immediately remove the battery 1st thing
2. Disassemble a bit... In this case remove the 7 screws on the back and pop the back plastic with 2 guitar picks
3. Use 90% rubbing alcohol (or better 200 proof moonshine if you can get it)
The drinking alcohol is better at getting the h2o molecules to adhere to the alcohol molecules, but rubbing alcohol is plenty good enough.. Immerse in the alcohol..... Like..... totally under , so you will need a decent volume (ahhh use rubbing alcohol, no reason to waste all the good Redneck Sambuca ingredient)
4. Leave for 30- 60 min minimum ...I have left over night a Nikon body with no ill effects then clean with cloth or paper towel and one of those cute brushes you wife has for makeup (clean no makeup plz)....... to dry, then inspect with a loupe carefully. Once you know there is no discernible damage then you can put in rice over night blow it off with compressed air from a can reassemble and try it out.
The most important thing about salt water is if voltage stays on the device with saltwater it will jack the electronics faster than a fox running out of a hen house.
Hope that helps
That's so surprising to me... I can really just drop it into alcohol? That doesn't cause damage to electronics?
I don't think there is any more water.. so what does alcohol help do?
I did cut my phone off, almost immediately. I was forced to cut it on while out on the boat though. I didn't really know there was an issue then, left it on.
I cleaned the charging port well, left in rice... My phone is basically dead now, using the wifes nexus one now.
anyone know a legit place to buy the charging port?
The alcohol causes the water molecules to attach to the alcohol, which prevents the water from causing damage.............. chemistry........ gotta love it, But without the water the salt can not cause electrolytic reaction thus preventing the corrosive effect. Also most of the circuit boards have conformal coating (usually a urethane type these days) which gives the circuit board a water proofing, but solder joints and other places are not protected.

Very well put you've made me proud, if you want to be completely sure you are cleaning the surface completely see if you can get your hands on pure acetone (stuff is in nail polish) it will remove any organic residues that might facilitate corrosion, afterwards a rinse with distilled water could be allowed.
-Cheers
What about mobile tech videos? I'd link but I'm on my phone. Those guys do repairs. Sorry I don't have any expert advice. But if you have to send it off ill make a donation towards the repair bill.
Well, looks like i'm a blackberry user until I can try some of these great suggestions.
I had no idea you could submerge your phone in those liquids.
Once i'm off this island, I'll try and break the phone down and see how bad I am.
Anyone know where I can buy the charging port?
Greggory, Very kind if you to offer that man, not sure I'd feel right accepting that. I'll check their site out. Can you pm me any information about them?
I sent you a pm.
You can sign up as a refurbisher
Phone is completely (COMPLETELY) disassembled.
Corrosion honestly does not seem as bad as I expected.
Off to buy acetone. So I can really just leave the mother board and drive reader in this liquid?? Casey... I trust you, but dang that is scary to me!!

something else I forgot, if you are in a place where you cannot fix immediately, then Pull battery as fast as you can and then wash in fresh water if nothing else or Jack Daniels
Putting a whole phone full of electronic things in alcohol seems unsafe to me, and since idk anything about this subject it also does seem like the phone would be MORE screwed up if you did that but idk so go ahead.
I'd try and think my way into getting a refurb
alright, completely broken down, acetone on many of the parts (dabbed most)... submerged for a minute or so on the USB/charge port.
Good news: the headset icon has now disappeared, so that's fixed.
Bad news: my vibrant still wont charge.
I think I need to buy a new mother board or charge port. Anyone know the best place to buy one? Going to register on global direct now.

It is just basic Chemistry, understanding compatibility interactions (or reaction is the key) with almost All electronics Alcohol really is pretty benign. De-ionized water is the preferred cleaning agent but then it usually is washed with pure drinking alcohol to make sure there is no remaining water molecules left.
Acetone is pretty safe EXCEPT some of the plastic that the housings are made can be reactive (dissolve from it) to it. So, even though the electronics are safe the housing could possibly lose its shine (become dulled).
BTW, it is this understanding of chemistry (or lack of) that causes so many manufacturing and installation/assembly problems. People change mix designs all the time and forget to inform others of the change thus causing recalls , lawsuits, etc.
Hope you get a new mother board S15274n

Called Samsung and they said I still had warranty until OCT (suppose they add 3 months on from the 1 year mark). I am going to take my chances and send them my phone for repair.
I'm not hopeful, but we'll see what I can talk their tech into.

appreciate the very kind words. Phone is with UPS now, en route to samsung. I imagine they will easily notice I have opened it, did the gps hardware hack and completely disassembled it... not to mention the corrosion that I did not get off the charging port, haha...
o well, if there is a miracle, they will just send me a refurb and not bug me. The techs are supposed to call if they will not repair it... I'll see if I can talk them into it.

I have had my Prime for a week now and it was working perfectly. I got the ICS update and everything was working even better. I never had any wifi connection issues. Today the prime will suddenly no longer connect to wifi. It appears to not be picking up the wifi signals anymore. When it does manage to pick up a signal it shows up as a small dot and still can't connect. It wouldn't connect at work this morning and when I came home it connected for about a minute and then dropped connection and would not connect again. I rebooted several times, tried a hard reset and then finally resorted to a factory reset. It still did no good. My unit was previously picking up my wifi signals with full strength usually and sometimes 3 bars. Not sure what happened but I guess I'll just take it back to Office Depot for a refund while I still have time. Not sure what I'll do now because i REALLY liked the prime during the time that it was working right.
If you're under warranty Asus will tell you to return it for a fix and hopefully their turnaround time is measured in days, not weeks or months. Sorry for you, it seems the Prime is not as durable as I thought, poor quality control is probably the culprit.
I would go the repair route but I'm kind of afraid that I'll then get stuck with it if they can't fix it and I've missed my return window at office depot. The bad thing is that there is no other tablet that I'd be satisfied with now that I've experienced how smoothly the quad core tegra 3 Prime runs. I had a Xoom before the Prime and I gave it to my fiancee after the Prime arrived. I really liked my Xoom too but the Prime is a MUCH BETTER device (when it worked).

Haven't heard of this issue yet, that is a new one. If you are in warranty, take it back and get a full refund or a replacement. If not, contact Asus.
However, good luck with contacting Asus and getting a timely response. I am on day 3 of just waiting for a return email. I did it through their own messaging service on their site, not regular email. I would appreciate someone responding to my simple questions, but they must not have the time right now.

I know that is why I was so shocked when it happened this morning at work. I was hoping that it was just something going on with the wifi connection at my office. I now that there are Primes with bad wifi out there but mine doesn't just have a bad connection now, it can't connect at all. I figured that I had been lucky enough to get one of the good units considering how incredibly well it had worked over the past week. At least I've only had it for seven days so I can still return it to Office Depot. I just hate the thought of being tabletless now. Guess I gave my Xoom to my fiancee a little too fast.
Well my prime got to the point where it would connect when I was next to the router but would either drop out or lose signal strength when I moved away. I have scheduled for a return to office depot. Yesterday I found another prime in stock at hh gregg so I picked it up. This one once again has excellent wifi service just like my first one did for awhile. I am hoping that this one keeps it. I still can't understand what happened to my first one. The only thing that I had done before the wifi crapped out was install a memory card and I don't see how that could have had anything to do with it. This experience has shown me though that the prime is definitely capable of giving good wifi service and that there is something going on other than the aluminum backplate. Having seen both sides of it I can see why no one would be satisfied with the wifi performance it had when it went bad on my first one. Maybe it is a mechanical issue with the wifi antenna connections coming loose in the system? I don't know how likely that is but it is the only thing I can think of based on my experiences with the issue
It very well could be the antenna wires are coming undone from the Wi-Fi adapter it would allow you to connect right next to a router but not much further away.
Sorry to ask the obvious, but did you power down your Prime before starting again to see if the problem was still there. I'm sure this was the first thing you did, but just checking.
The wifi on my Prime cut off last night but it came back after a quick reset (holding down the power button for 13 seconds or so).
Yes I powered down, tried a hard reset and finally tried a factory reset and none of that helped with the problem. It was a complete night and day difference in performance that was quite shocking. As I said if people are experiencing that kind of performance from the beginning then I can totally understand the complaints. So far the new unit is having the same great performance as my other one had at first.
From looking at the Prime teardown, your wifi loss may be due to a loose connection. Instead of running a pigtail directly from the chip lead-out to the antenna, the Prime uses spring-loaded pogo pins (1st pic) as intermediate connectors.
Second pic shows the pogo pins for the main wifi and GPS antennae. The spring-loaded pins are pressed against the copper pads of the respective antenna (3rd pic). Suffice it to say, this isn't the most secure way to connect the antennae.
Aside from possible broken or intermittent connection, it also looks like a high-loss connection, and could contribute to attenuated signal reception. My guess is that this may be the main culprit of wifi/GPS woes, with the metal shell being a contributing factor.
The 4th pic below is a U.FL connector that's normally used for antenna pigtails. The lip has an outer overhang for a secure connection.
My guess is that the tablet was bumped and something shifted a bit, breaking the antenna connection.
This is FYI only, as the unit isn't user-serviceable. It does look like a simple fix, but you'd have to open the unit. Edit: You can try smacking the top edge of the tablet a few times and see if it will jar back into place. Worth a try.

Heck yea it's worth a try!
And to the OP - since it only just happened today, I think I would wait a day or two to see what else might develop. I know you've tested it out in two different places, but it came on so suddenly, maybe (hopefully ) it will go away?
Unless of course waiting a day or seeing what might be different tomorrow would interfere with an exchange or return policy. If you are still within a window and are out of time soon, then you gotta do what you gotta do.

Before packaging my Prime up to be sent to ASUS for RMA. I did exactly that, I did the black part of the screen at the top with my kunckles kind of hard a few times.

You really can't use terms like "good" and "more" beacause they're all relative. "Good" compared to what Wi-Fi/GPS is with other devices or against other Prime's? And until it's known for sure that all devices are suffering some type of signal issue saying the unproven pogo pin expose is "more" or less an issue than anything else is premature. It's impossible to compare Wi-Fi performance on a forum because each testing condition is different and there's no baseline to have a common discussion around. To see if there's differences between Prime's a couple of them need to be tested side-by-side at the same time.
hang in there demadarin - I think Barry is weakening and we will eventually convince him there are potential issues beyond the back plate.

I'm like Spock on Star Trek - it's all about logic. It seems more and more people are having their signal change when squeezing above where the antennas are. That certainly points to a common issue. But even the hand-picked Prime Asus sent to Anand to replace his defective sample still peformed poorly against the TF1. So the metal back cover's not an innocent victim (yet).

Look at it this way, when Apple move the antenna from behind a plastic disk on the iPad1 to behind a metal speaker grill on the iPad2, performance took a hit. The Prime has no opening at all for a signal to travel through and Asus makes less in a year than Apple spends on R&D. Ergo, the metal back cover is and will remain a factor.

Agreed, but by how much in comparison to a tarnished pogo contact? And as time goes by, the influence of the latter will be increasingly pronounced. BTW, the TF101 does not use the pogos, the antennas are hardwired. I also noticed that the mainframe is made of solid aluminum and yet the 101 has never had any rf problems like the Prime.
With users experiencing sudden change in signal level after making good contact with the antenna, I'd say the evidence of inconsistency in performance is pretty convincing as to the real cause of the fault.

You really can't use terms like "good" and "more" beacause they're all relative. "Good" compared to what Wi-Fi/GPS is with other devices or against other Prime's? And until it's known for sure that all devices are suffering some type of signal issue saying the unproven pogo pin expose is "more" or less an issue than anything else is premature. It's impossible to compare Wi-Fi performance on a forum because each testing condition is different and there's no baseline to have a common discussion around. To see if there's differences between Prime's a couple of them need to be tested side-by-side at the same time.

Correction needed here. Anandtech last tablet test held prime wifi on par with tf-101. Then he also said range "Might" be an issue. He never said Prime wifi performed badly after his last test.
Nice try trying to sneak that one past me we all guilty of loving to pick n choose info relevant to what we want to prove..lol
I’ve been struggling with why my GPS quit seeing any satellites after the 9.4.2.11 update when I realized something looking at Anand’s teardown:
AnandTech - ASUS Eee Pad Transformer Prime Teardown
Perhaps the antenna connections are weak or have become slightly corroded. Based on his teardown the contacts are spring type “pogopins” which mate with the opposite face. With that thought in mind I decided to try and flex the tablet ever so slightly to clean the contacts. The idea being that the slight flex would cause the pins to scrape the contact surface rubbing a clean(er) spot.
Before the 9.4.2.11 update I had the typical poor performance from the GPS, getting locks but losing them on the move. I had given up on it [GPS] until this update which touted GPS improvements. After updating and wiping I tested the GPS again, but could not see even one satellite after letting it sit, more than once, for over an hour with Wi-Fi on and off.
I must stress I strongly suggest you do not try this on your tablet for fear of damaging it. I take no responsibly for damage to anyone’s tablet and am only reporting my actions.
After this procedure I am able to see several birds indoors, albeit with weak SNR. This has me convinced that part of the problem is related to these contacts, and may serve to explain some of the weak Wi-Fi reports. It may also help illustrate why only some users are seeing issues, and perhaps why some of the returns are functioning better. These contacts may be more robust in some units or possibly be able to be rectified via service.
I do understand there are other factors related to both the GPS and Wi-Fi, but this appears, at least to me, to be part of the bigger picture.
Please note that the amount of flex I’m talking about is next to nothing, enough to see a change in light bleed around the display, I was afraid to go too far.
*Mods, I'm not sure why this post was deleted before, please PM me if there is a problem with this post. I did not include the link.*
Hi jhovak,
that sounds very interesting and makes me nervous thinking of manipulating a new device. You are brave!
Do you have some pictures of your action?
Thanks.
Cheers,

You can bypass the pogo pins by connecting a pigtail to the UF.L connector at the chip leadouts, then solder the other end to the antennae's copper pads. It should improve reception.
e.mote,
Looks like you beat me to this I never saw your post, but that's exactly my thoughts. I was able to torque it a bit to get it working again. That maye be what they are doing to get the RMAs reported to work better, "fixed".
motocamp,
Unfortunately I don't have any pictures of the process, but you wouldn't be able to see much, I only deformed the case/screen very slightly. The problem is you may end up popping other solder joints in the process.

I agree. Makes perfect sense to me.
Everyone has the same aluminum back, so you would expect the same results across the board (barring weather and atmospheric conditions) for all Primes. There has to be another piece to the puzzle of bad GPS performance when some user's report GPS working and getting locks and other user's reports no GPS active with no satellites seen and no locks.
Thanks e.mote for your explanation of the antena contacts. I think you hit the cause of the GPS problem. Hopefully ASUS saw your post and address this prioblem so it does not occur on their the planned 700 series.
Cheers
I forwarded all this info to Gary in a pm just recently. including details, link to that thread e.mote posted in and that teardown showing pogo pins. hopefully he will get it soon and pass info to engineers.

pardon my lack of GPS knowledge but what is considered good or bad when comparing GPS in general? This is my prime outside earlier but there were fluctuations
I am a bit more skeptical about the hardware pins as a sole cause. Reason:
I had pretty decent GPS performance until this last update which totally killed my GPS performance. This suggests to me that there is a firmware/driver type component to at least some people's problems. The same update did correct other people's problems. So perhaps there are some slight differences in the GPS chips that the firmware is not playing nice with or accounting for?
I can confirm this at least partially works. I tried to drive home using GPS test the other day from work and could hardly get a lock especially at high speeds. I saw this and did a number of squeezes aroung the area of the GPS connector and had a significant change.
Drove home with GPS test today and I hardly ever saw it not locked, even going at 70mph, though it would go between 2 and 8 locked sats or so. Halfway through the drive I opened google maps. It took 10-15 seconds to lock, but then I watched my blue arrow follow the road exactly almost the entire way home. It only lost lock when I was stopped under an overpass at a stop light.
To be clear the signal strength is not that of my phone, but at least it's working now.
Have you seen the new evidence found? It was found out that Original Transformer actually uses the soldered type connection E.mote described. I was gonna start a thread but no use as this one is perfect for the new info.
FIRST here is the quote n pics from e.mote of the current Prime type of connection
e.mote said:
From looking at the Prime teardown, your wifi loss may be due to a loose connection. Instead of running a pigtail directly from the chip lead-out to the antenna, the Prime uses spring-loaded pogo pins (1st pic) as intermediate connectors.
Second pic shows the pogo pins for the main wifi and GPS antennae. The spring-loaded pins are pressed against the copper pads of the respective antenna (3rd pic). Suffice it to say, this isn't the most secure way to connect the antennae.
Aside from possible broken or intermittent connection, it also looks like a high-loss connection, and could contribute to attenuated signal reception. My guess is that this may be the main culprit of wifi/GPS woes, with the metal shell being a contributing factor.
The 4th pic below is a U.FL connector that's normally used for antenna pigtails. The lip has an outer overhang for a secure connection.
My guess is that the tablet was bumped and something shifted a bit, breaking the antenna connection.
This is FYI only, as the unit isn't user-serviceable. It does look like a simple fix, but you'd have to open the unit. Edit: You can try smacking the top edge of the tablet a few times and see if it will jar back into place. Worth a try.
Pogo pins used as intermediate connectors for wifi & GPS antennae

Just got PM a lil while ago from Gary n response to the thread n possible pogo pin issue. He said this is something the Engineers are looking very closely at on units being returned to be looked at or repaired. SO things are moving right along. FOUND OUT ALSO my serial number that starts with BCOKA is actually from an early batch that I guess had the older hardware. Engineer or Service person supposed to call within next 48hrs. They are going down the list of people that Gary got serial number, email, and phone number info from. I guess it must be a big list...lmao
SO if I do have to send it in, then they will be adding the new hardware it and hopefully changing those pogo pin connections to soldered ones..lol
Ill know more details once I get their phone call. If I do have to send in, I hope they don't wipe everything as I have around 150-200 apps n games. Things customized n all that. Ill take the new hardware though n hopefully won't go thru the horror stories I've been hearing about on returns. OR ill like it better if they just sent me a brand new tablet with the latest n greatest hardware changes on it then I send mines to them. So it'll give me time to transfer things to new device if need be.
I HAVE AN APP on my Ipad called applist that will list every app you have installed and allow you to email the list to yourself. Does android have anything like this?
Wow. I think we can all agree that Asus dropped the ball in so many areas with the TF201. Who the hell wants to put up with this nonsense???
If only Motorola would build a tablet with a docking clamshell keyboard they could probably take 80% of would be Transformer customers. I'd be first in line.
But what could be the reason ASUS changed to use this pogo pin?
Weight? Cost? ... Sabotage? ... I simly dont understand the engineering thought of it.

It would take alot more than that for Motorola to come up n take Asus customers. The xoom, first HC tablet, was a complete flop. Plus Motorola known for locking their systems down, at least initially. MOTOROLA IS NOT too popular of a brand these days, at least tablet wise.

Good to know BCOKA is from an older batch, have such a unit as well and very crappy GPS and also suffer from mediocre wifi combined with bluetooth degradation.
Also contacted Gary and will keep an eye out for any developments (live in EUrope though).
The majority of Prime users don't root or flash their tablets. Maybe the majority on this site but not the majority of the total users. So I doubt that will dictate the winners in this market.
Secondly, you can't debate that Motorola's hardware prowess is vastly superior to Asus. And definitely good enough not to pull these bone head mistakes that Asus keeps rolling out one after another.
The Xoom wasn't the sexiest by any means but it was solid as a rock functionality wise. Now with the Xyboard and their follow on products improving in the looks department I really do think they could take would-be Transformer customers if they would just offer a keyboard dock.
And if you're wondering the reason I'm not getting a Galaxy tablet, the reason is because their RF electronic know-how is not too much better that Asus's. I gotta say though that at least Samsung had the intelligence not to seal their RF electronics in a Faraday cage. LOL.
I keep on hearing many reviewers calling the USB cover annoying and inconvenient. First of all its brilliant, because it's better have one than to not because long term it brings benefits. It also means that the design doesn't cut any corners interms of how a mobile phone should be. I realised this when I noticed that all good phones before iPhone all had these flaps even samsung. But when everything went touchscreen they stopped the flaps, if iPhone or samsung make flaps on thier phones its a brilliant idea, nobody will complain like they didn't when it was a standard to have a flap but when HTC does it or Sony because It's different everyone bashes the idea.
I can remember when all TVs where made out of metal and remotes, now everything is plastic meaning hardware no longer has a quality feel to it. The only tv manufacturers that still use metal are B&O. I know that having a flap is flimsy but compromises have to be made for quality like a Rolex or something prestigious they will look nice but will always be heavy. All I'm trying to say is theirs no need to hate something that was saw as a standard and I'm more than happy to have it because other flagship phones don't which gives it a design advantage, it looks neater and it means more effort has been placed in this handset.

In my opinion the biggest benefit of the USB cover is waterproofing. Wireless charging and Airdroid cover me for the rest of what the USB cord would be used for.
From the Engadget review, they stated that the USB cover was added to help make the phone splash resistant like the Butterfly, if that's the case then this is awesome. The only issues are that it's going to be harder and more expensive for car docks.

Motorola's Atrix HD and new Razr line are all splash resistant but they dont have covers
the reason everyone hates on the cover is because it's an extra step needed when connecting a USB, but at the same time because of the wireless charging, you're going to be using the USB port a lot less, thus it's better to have it covered so it wont collect a bunch of dust inside from having it exposed, and at the same time it's not going to be an inconvenience too often to take the cover off when you do need it.
it is a slight pain to have to remove, which is partly why i picked up a charging pad for the office and will soon be picking one up for home. i do like the idea that it is covered though since i do carry my phone in my pocket and its like a lint factory in there.
i am curious to see how an otterbox or other rugged case looks since those usually cover the ports anyway
Nice to hear that you are all adopting the idea of wireless charging, I like the idea but I have a feeling apple will make one and it will charge quicker and look better. I could only imagine the ads for the iPhone 5S bragging about wireless charging as if they invented it and they probably try to patent it.

Well apple clearly mentioned they dont like the idea of wireless charging coz you still need to plug a wire in the wireless charger. That said they also didnt like the idea of 7 inch tablet.
I personally like the idea of wireless charging especially with starbucks already providing wireless charging on there tables.
"Well apple clearly mentioned they dont like the idea of wireless charging coz you still need to plug a wire in the wireless charger."
If apple said this ... they should be ashamed because that is wildly poor reasoning ... there is much less effort on the users behalf and a greatly improved experience when you just have to lay your phone down to charge it... that being said I'm sure ape said that because poor reasoning skills are their signature ..

It's actually gotten easier for me to open and close. It took some effort for a few days but now I can do it without really struggling. I find it's much easier to put in the non-attached end first.
The only issue I have with it is desk docks or stands won't be as easy to use with the flap in the way. Granted wireless charging would help, but I'm still not particularly sold on it yet.
After trying to live with it for a few days, I'm going to cut my cover off.

Holy crap some of you people are so lazy. I could see maybe the flap being a bit annoying, even if you get used to it and it's really not that bad afterwards, but some of you think even having to connect a cable is some huge effort? It's not even a consideration for me that connecting a cable is any real effort at all, and I can't really understand how it could be considered that.

How did you relate annoying with lazy?
It is a typical annoying HTC move. People wonder why HTC is losing money every year, it is because of crap like this. Sure, it may not seem like big deal but all the little details add up. There are a ton of problems they seem to ignore and now they just added another one.
Flush buttons.
Power button on top of tall or huge phones
USB port on the side of the One X
Dumbest multitasking set up ever
Horrible carousel when scrolling through wallpapers and skins.
USB port flap.
Etc.
The reason the flap is annoying is because that flap will wear out faster that the rest of your phone unless you strictly use wireless charging. Every other high end phone you can keep it mint way easier without a flap you have to open every night or even more with the crap battery.
Here is a pic of the last phone I owned with a cover like that. Over two years of service and beat to hell and back. I'm not to worried about durability. Of it does wear out it looks like it can be pulled out with pliers. Kinda like those plastic things they put in shirts with the price tags on it.

step 2: on the right side of mobo under the black circle fabric (below the fabric DO NOT REMOVE FABRIC JUST LOOK UNDER IN) YOU WILL SEE 3 little button nubs.
each nub has a little bent peice of metal facing upwards. Each one needs to be pushed up a little more. the problem was they are not hitting the ribbon connection to give them power on the back casing.

Can confirm this worked for me, here's an album if y'all want different angles on the phone
Confirmed as working for me too. I've done this mod on 3 phones already, all are a success. LG is horrible... Releasing phones with such blatant defects.
It will stop working after few days, cuz those are volume pins, has nothing to do with gps
If thats the real fix and the battery touches it, I'm almost certain that replacing batteries is causing this. It explains why many are reporting the issue coming back overtime when warranty replacing. My replacement is already getting worse GPS signal
Actually, makes sense these buttons are related to the volume buttons... There are multiple leads on the board connecting to the back of the case directly though, making me think that LG chose to use the "metal backing" as a GPS antenna. I've straightened multiple leads on the board which come in direct contact with the case itself and other elements just in case, but I have a feeling this will be an issue that plagues us G5 users until a hardware revision is done by LG...
Time to shop for another phone. What a bad investment this was...

Horrible how us early adopters get rimmed...
To be honest, I think those three leads do nothing but placebo after looking at the board... But notice all the leads across the board which connect to the case itself. I think those would be a better spot for GPS and phone antennas... Wish someone had a technical diagram for us.
As for the HTC 10, I've heard good things... Just not sure I'll be able to sell this phone to buy one.
Signal still holding strong today... Getting massive signal with no drops.
Is this problem still present in current versions? Or was it fixed? I can't believe LG still sells this phone with GPS not working? I get a G5 the next days, how can I check if mine has this issue too?
How ? I don' know dude, maybe, but just MAYBE you could install gps status and check it.........
I just read the "fix" and I just realized that this fix is total garbage. It can't work.
"each nub has a little bent peice of metal facing upwards. Each one needs to be pushed up a little more. the problem was they are not hitting the ribbon connection to give them power on the back casing. "
Everyone with normal reasoning can totally realize, that this "mod" will eventually fail again, really really soon, mostly after a few days, and you can read that btw already by lots of people, for example here:
https://m.reddit.com/r/lgg5/comments/4u8m9p/how_to_fix_your_gps_fixed_in_10_minutes/
Metal tends to change after some time or temperature / pressure, and it will fail again.
Why did no one develop a clever, simple and working mod so far? Why not just soldering a bit of liquid silver on the three contacts, with a bit of metal plate on top to make it 1-2mm higher? Or just even more simple: Do it on the backplate contacts.

Why did no one develop a clever, simple and working mod so far? Why not just soldering a bit of liquid silver on the three contacts, with a bit of metal plate on top to make it 1-2mm higher? Or just even more simple: Do it on the backplate contacts.

To me, personally, I don't mind being a little bit critical, but with this response I think you are to direct and judgemental towards the topic starter. Topic starter has given his best to share his practice. And I agree with you this one will probably not last, but let's keep it friendly.

I just read the "fix" and I just realized that this fix is total garbage. It can't work.
Everyone with normal reasoning can totally realize, that this "mod" will eventually fail again, really really soon, mostly after a few days, and you can read that btw already by lots of people, for example here:

your answer is total garbage. ever seen a car that scraped on the ground because the shock absorbers failed due to temperature and high pressure just by existing?
unless you bend them over and over the method will most likely last for many years. you dont have a lot of forces acting on it.
if you make a fixed connection like soldering, the small dynamic forces would eventually weaken the material and it would break after some time. think before insulting somebody's idea
i don't think those are GPS antenna contacts.. as i used to observe that gps antennas usually have 1 or 2 contacts.. never 3! but they could do..
don't know if you read my topic about same issue and another "fix"..
at the moment we have 2 confirmed informations:
1) if you isolate detachable module pin connector you'll get no gps at all
2) gps will work good until you'll detach and reattach battery couple times.
this could explain why LG released this terminal which definitively passes any factory test! ...holy real day-use tests!

we have 3 different gps systems on our phone so 3 makes sense. BDS (beidou) is only to be found on the newest hardware

thanks, i've also tried this fix and seems working.. but indeed volume rockers are nearby and no other connectors were found.. mistery grows up..
this fix save me, thanks for it, now the gps works fine

You can read, right?
1. look at the link. lots of people already claimed the """mod""" lasted about 2-5 days, then the problem came back.
2. what are you talking about!? Those contacts between the board and the backplate are based up on pressure. The mod just says "try to bend them upwards a bit". THIS MEANS IT WILL TOTALLY GO IN ITS BASE POSITION AGAIN REALLY SOON. It can't work.
3. back to, if you can read. Where did I say soldering it? Right, no where. I said put some layers of conducting anything on the backplates contacts to grow its height.
Not enough forces acting on them? Seriously? So to your logic, this means this problem wouldn't occur in the first place. Pressing with your fingers on the cover at that very place mostly is enough to push them back every time a little bit., also because they're at the very edge of the cover.
