XDA GSM Signal Reaquisition. - MDA, XDA, 1010 General

I posted this message at www.pdaphonehome.com but I thought I might give it a shot here and see if I can get diffrent results.
I'm in Sydney Australia and have recently puchased (brand new.. not off of ebay or anything) the O2 XDA (32/64mb). Rom version is 3.14.17 ENG with a Radio version of 4.16 and have encountered the dreaded SIGNAL LOSS / REAQUISITION problem.
I switched from a Treo 270 (which had the dreaded back light problem) and absolutely LOOOOOOVE the XDA (plus the fact that I can code VB apps for it too is kinda nice without paying for the dev env) aaannnyway....
(is it me or does it seem like most PDA-Phones have at least one Dreaded Problem).
I'm currently with a carrier which has almost no signal at my workplace (vodafone) and am at least 12 months away from my contract ending so swapping carriers to the better Optus or Telstra is a no-no.
I've managed to trawl around and managed to find some information on the Signal loss / reaquisition.
1) The phone takes an awfully long time to reaquire a signal after coming back from an area with almost no signal. I've managed to time it and on average it seems to take about 10-15 minutes to reaquire. It also needs a STRONG signal to reaquire it and will take longer to reaquire if it's a weak signal.
2) Occasionally the phone gets "stuck" and while it reports a full strength signal, no-one can seem to call or send SMSs
I've tried to use "Phone Today" and it does seem to make little or no diffrence in my situation.
From what other sites (as well as this one) have reported, it has something to do with people only in fluctuating areas of signal combined with a long refresh interval on the phone rather than a defective phone. Am I right?
What I'd like to know (throught your wealth of contacts) is the following.
1) Is O2 Aware of this problem? I've seem forum postings where O2 have admitted to it. Can anyone confirm this? I managed to contact O2 Australia and they've denied (surprise surprise) any knowledge of the problem. Mind you I'm not sure how prevalent the XDA is in Aus so the guy on the phone may have been genuinely ignorant of the problem)
2) Can anyone confirm whether O2 is working on a patch or update for this. I know an ETA is too much to expect but some acknowledgement would be nice.
3) I understand that the AT&T SX56 is practically the same machine and it has it's refresh rate set to 90 seconds as opposed to o2 which I'm assuming is every christmas (but only if you feed it cookies). Would fixing the problem be as simple as using the radio rom from an AT&T on a XDA?
4) Is there anyway to hack the radio to up it's refresh rate? (might breach some copyright laws ... apologies if I've stepped on anyone's toes)
5) Is it true that when it tried to reaquire a signal, it goes into a high frequency seach mode (or something like that.. I don't know.. *sigh* ) which chews up more power? Does this mean that if a more frequent refresh rate were to be implemented, the battery life would decrease significantly?
**new addition**
Since I do have a little knowledge about emVB may be a temporary solution might be possible if I could code one.
Is there an API / for the GSM component of the phone. I noticed the "register on network" button seems to force the phone to reaquire the network if there isn't any signal. I would be nice to write an app to detect a "no bars" status on the phone and get it to hit the refresh button (or at least call the function) every minute or so until it finds a signal.
Any hints?
I may be hoping for a little too much here but it never hurts to try right? Thanks in advance.

XDA fails tto turn on phone
This looks a lot like "XDA fails tto turn on phone." in http://www.sourceo2.com/Communities...tm?frameset=found&NewsGroupID=8&iPageNumber=1.

Thanks for that I'll have a look-see. Didn't know about the SourceO2 site's communities.

I checked the site and it seems that it's pretty much the same gripe everyone's whingeing about. O2 doesn't seem to say anything about it and some poor guy called "xdaguy" seems to be taking all the heat. I don't envy him.
I'll live with it a while longer if not, it's back to the store and since there doesn't seem to be any other PPC phones apart from the XDA here, it's back to the treo.. Booo Hooo.. No MP3's for me anymore
Thanks for pointing me in the right direction anyway.

Paper clip to boost signal
Yes, a paper clip...
I too have experienced just the other day A weak signal to a no signal at all...anyhow here's how to dot it ( at your own risk of course)
1. Bend to straight the paper clip
2. Strip the plastic cover off the metal paper clip using a blade or a small box cutter.
3. bend 1/4 of an inch at a right angle
4. Remove rubber cover beside camera lens
5. Insert the 1/4 inch bended paper clip into the female socket
6. wait for signal
Note: this is only TEMPORARY of course as am looking into the after market antenae booster

hi - looking for a solution to this. is there any?
if my phone loses the signal it won't regain it.
I'm sure i read somewhere that this is actually a design fault and the xda (version 1) is only designed to try to regain signal for 30 mins then give up. That right? Can it be fixed?

I used to get this but a soft reset usually got it back online.

Silver Shield Xdaiis Mount

HI everyone.
Ok, so my luck with mounts runs parallel to my luck with women. Got one, just not the right one... b'doom - tchsss!! (always open with a joke).
I can get the sounds coming through the speaker fine (though I have to not plug it all the way into the XDAiis) and it accepts voice commands etc, the only problem is - the damn "dibide dibide dibide deeeeee" noise that keeps coming through the speaker!
Is there no way to guard against this happening? (in case you can't work out my phronetic typing, I mean the interference caused by the phone's radio waves (or whatever the hell they are).
I saw mention of an external antenna for the phone - surely not - there must be an easier way - wrapping in tin foil maybe?
If there's a secret to getting this to work without interference, PLEASE share it - it's driving me potty!!
Jsedit. (happily married until five minutes after I hit submit)
the easyest way is to swap to a pcn (orange)network not gsm(o2) pcn transmits on 1800 mhz and does not usally affect electronics as bad.
all vw car radios phone input suffers the same problem on o2 and vodaphone, orange and tmob are fine
Believe me, in January, when my contract ends, I'm going to go back to Orange!! But for the time being, I'm looking for something to stop this until then.
(Not that I'm completely unhappy with O2, it's just there's SO many thigns you have to forgive (Not getting reception in the area where I live being a large one!))
Thanks for your suggestion, more ideas welcomed.

signal issues/death grip???

no I love my sgs2 and so does every that holds it, ive a major issue that i thought was caused by switching from orange uk to o2 uk, but as it happens i have full signal when the phone is rested down... however when i pick it up it drops signal... more often than not the signal completely drops out as does the call and sometimes it just goes down to 1 bar... does anyone else have this problem? ive tried my o2 sim and my orange sim its the same for both... is it possible i have a defective handset ? weak radio ???
heres my quick vid to show you what i mean, apologies for the video quality... filmed on my bb9700
http://www.youtube.com/watch?v=9VthdB4V3D8&feature=channel_video_title
well the GSM and 3G antenna looks to be located in the bottom, back part of the device. so this seems like the exact place your hand would be covering when holding the phone, so i can easily see some significant signal attentuation happening with this phone.
i dont know where the antenna was located on the original galaxy s. but all phones i own always have attentuation. not much you can do about it i'd guess.
Applies to all wireless devices - signal transmits worse through your hand than through empty air. Rules of the universe.
However, I can't seem to replicate what you're seeing. In order for bars to drop, I have to block the entire bottom of my device using both hands. Holding it in one hand doesn't seem to be causing a drop for me.
But again : air > hand for signal transmission.

That's right, quick start guide shows the location of the antenna. If you look at the back of the device, the antenna is in the lower left hand corner, opposite the speaker.
When holding the device in your right hand, it should rest in your palm.
Actually holding the device in my right hand doesn't seem to be affecting my signal though, for some reason. I might just be in an area with good signal though (3 bars of h+, stays at 3 bars when holding it in 1 hand, drops to 1 bar when covering the device completely with 2 hands, and then changes to edge with full bars).
I just tested with my S2 and I had no problems whatsoever.
See my youtube channel (../user/Poppefieke) Can't post links yet.
I have some other S2 video's there too
i think sampullen who has been posting quite a few vids on youtube is going to cover this now too, see i hold my sgs2 in my left had for holding when im surfing etc but also when im on calls...
its good to hear some of you cannot replicate this, maybe mines faulty might try to exchange for a new 1 just to be on the safe side
OMG!
can more people confirm if this is real?
is it as bad as the antenna-gate issue from apple or no where as bad
Hey (samjpullen) here
I have been doing the tests like Sticky and have been getting some rather conflicting results to say the least.
I am not in the best area for Orange so i get a weak signal most of the time, when i do the test infront of my iMac and extra screen with the TV, Sky (you know the drill) on it seems to drop down from H with 1 bar, then down to 3G then down to G and then it can jump onto the Edge network (rathe strange)
But when i do this same test in other rooms e.g bathroom, other bedroom, even downstairs with the tv etc on it is fine!
So my guess is that it might be my rooms location and maybe all the electrical equipment within a small space.

im hoping no where near as bad and im hoping that i was the only affected, one chap has placed a video reply to mine showing he doesnt have the issue which is good news, lets hope more can confirm im rather a 1 off and that if i replace this unit all will be well...... fingers crossed
cheers sam,
btw ppl follow sam on twitter, guys good!!!

Serious wifi issues

i know this have been discussed before but there is still no solution.
here s my problem: wifi signal drops suddenly when i hold my phone. ive done sevral speed tests. These tests confirm that holding the phone results in a really bad wifi quality. I ve tried eveything.
does anyone have any ideas? even if its hardware moding
thx
+1
Sad to say, in my tests, by tightly holding the phone, especially at the bottom right, the signal strength reduced by about 20dBm.
Sent from my XT910 using XDA
this really sucks since this phone is pretty good and so far its the only BIG problem i found. and no solutions....
Must be a random problem. I have the RAZR and RAZR Maxx and neither has this problem.
For me, on 2.3.6 wifi signal was low, especially taking phone by bottom, but on ICS, both t-mobile ics and latest eu ics, wifi signal is very improved. Hand issue remains, but signal is for me stronger.
well i guess im just going to wait for stock ics update and hope it improves but im guessing the problem wont disappear since this is clearly a hardware issue. and if this is random then im very unlucky
When software fixes a radio that software usually just makes the signal-strength meter show signal that's not really there.
There are apps on Play that "fix" all kinds of radio problems by installing signal-strength icons with the low-strength indications set inaccurately. It *looks* like more signal, but it's the same low signal you had before.
Signal strength has almost nothing to do with reception anyway. Signal/Noise ratio is what's important, and there's no meter for that. One bar of signal in a very RF-quiet area, is much better than five bars in a computer data center.
"Caveet emter, I reckon!"
- Mark Twain
I have no wifi issues with this phone. The GNex however was unusable at 30 feet from a high-powered Hawking WAP, or an Apple Airport Extreme WAP.
If you have a plastic case, try removing it. Some cases are made with recycled plastic and are infused with conductive material that can act as a Faraday Shield, blocking part of the signal. Easy test, costs nothing but a few seconds...
yea i already knew about the plastic thats why i bought a rubber case. I have to say it helped a little but didnt fix it. the problem is still there.
thx
Haven't seen any problems with my wifi, although I mainly use the 3G simply because I have 4 GB of data a month and I will never use that much when I'm out around town.
If the problem occurs when holding it a certain way wouldn't the simplest solution be to not hold it that way, also be very aware of any metals between you and the router as metals block radio signals, how old is your house, if old enough maybe lead paint, unlikely but just throwing all possibilities out there.
thx for your help. i didnt only test this at home and as for holding the phone im used to hold it like i hold all phones and its pretty annoying if i always have to hold it differently if i want to use the internet
Have you tried the free Play Store app, WiFi Analyzer?
This will help you find out what works/doesn't as it provides more sensitive strength measurements from the chip. It's handy anyway, since it shows WAPs that you aren't connected to. yet.
It's quite possible that your antenna wire bounced off the connector. An insignificant drop of an inch could do that if it was never seated correctly. It would likely operate in a degraded capacity as a result. If you're OK with cracking the case open, that's something quick to check.
How long have you had this phone?
I have never heard anyone complain about the Razr's WiFi reception, so I suspect this is something unique to that phone right there. What is your idea of poor reception? 100 feet, inside, is the practical limit. 300 feet in an open field. Metal wall studs, sheet metal siding, all of these will stop radio waves dead.

Then you haven't been listening. The RAZR is universally acclaimed to have the worst WiFi reception of ANY device since 1999.
im ok with opening it... i actually opened it a couple of times and removed the battery but idk what to look for since nothing is labeled i dont even know where exactly is the wifi ship and antenna. i tested this as close as 6 feet from my router when i leave it on the table i get full wifi signal and speed test at max then i hold it and try... wifi signal goes down and speed test at 3/4 max speed...
thx
It's possible that I have an extraordinary phone then. I decided to compare.
My phone is seeing -60dbm from the Hawking extender that I'm closest to, which is about 20 meters away, behind three stick-frame (pine 2x4 studs, sheetrock) walls. The reading varies dramatically, depending on where I put it on my desk. So let's see what some other WiFi devices do...
My MacBook reads -58dbm. My iPad2 reads -59dbm. An HP Envy 15 reads -65dbm. And a Moto Atrix2 WCS (With Cracked Screen) reads -61dbm.
A transfer of 200MB ("random" data created via linux: 'dd if=/dev/random of=200mb.dat bs=1048576 count=200' so that compression algorithms don't skew the results):
Razr (6.12.79 ICS Black Widow): 9s
MacBook (Lion): 6.5s
iPad2: 10s
HP Envy 15 (Ubuntu 11.10): 7.5s
Moto Atrix2 WCS: 10s
I didn't repeat the test, and that is a busy WAP, but the results are what I expect for battery-operated devices. I also expected the ipad, atrix and razr to lose the race, since they have relatively slow storage systems, which have inherently poor write performance on files of this size (200MB won't buffer at all).
The WiFi cable will look like a white or black wire with a gold junction on the end where it meets the motherboard. I would expect that if you've had the phone open, you would definitely notice a wire hanging loose! I doubt that's the problem, but that wire is a coaxial shielded cable - like on cable TV only really tiny - and you can do all kinds of DIY replacement antenna stuff eg, adding an external jack so you can "beam" WiFi a mile away using a hacked Pringles potato chip can.
I actually think the problem might be RF noise in your environment. Florescent lights (CFLs), computing equipment, HVAC compressors, and motors can effectively "jam" WiFi signals, causing packet transmission failures to increase rapidly as the distance from the WAP increases.
We have a Fluke RF analyzer here, and our WiFi setup is quite good as a result.
Does anyone know if the Razr is unusually susceptible to RF noise? Maybe noise that the Razr generates from the motherboard/CPU/radios/BT? I'm not equipped to test that.
---------- Post added at 09:15 AM ---------- Previous post was at 08:29 AM ----------
Do you have other devices to compare the Razr to?
Did you try pointing all the rubber duck antennas on the WAP straight up?
I just checked an iphone, another ipad, another Razr, and a Dell laptop, and my boss's Razr was technically the winner on signal strength and transfer speed, but let's call it even. There are too many variables, and statistically significant benchmarking is beyond the scope of a forum comment.
The Razr has typical WiFi performance in this environment.
Thank you very much for your post. I did try with the desire z and the evo 3d which are doing jist fine wheather i hold them or leave them on the table: both signal and speed test are amazing compared to the razr (if i hold it). If you could tell me where the wifi ship and antenna are located (a pic maybe) it would be great because when i open the razr all i can see are metal plates everywhere probably for cooling. I dont understand what you mean by pointing all the rubber duck antennas on the WAP...
Thx again
I haven't had a Razr open yet. Even after dropping mine from a motorcycle and watching it slide into a ditch with an inch of water in it. Tough li'l bastards...
The WiFi antenna cable and connector are probably under one of the metal shields.
Most WAPs have 1, 2, or 3 "rubber duck" antennas that you can move to maximize the signal lobe pattern. You can use the WiFi Analyzer app to adjust them, but be prepared to walk a lot...
Others are just a box. The only one of those that *I* know of that works well is the Apple Airport Extreme. The Netgear Wireless-N HD, which is very highly rated, is a P.O.S.: it has a narrow, elongated lobe pattern, and if you're in that narrow lobe, it works REALLY well. If not, you'll be lucky to connect to it. Two people standing 10 feet apart, and one can have great service while the other can't even get an IP address.
The fact that you have other devices working well, and you sound like you've done this quite a bit, I'm guessing you have a problem inside the phone itself.
I manage about 200 phones here, and I haven't heard one word of complaint about WiFi. 3G/4G service? Yeah, lots of complaints about 3G/4G from people out in the woods or working in a valley.
These also work well as a WAP (tethering). We have a few of the Personal WiFi devices - a handheld that converts 3G/4G to WiFi for up to five users - but most people prefer this phone for that.
My old DroidX has a better WiFi antenna, but that's an exceptional phone with only one core: I spit on it. Ptui.

Contemplating buying XS

So at the moment I have a couple of phones that I really want to buy and the XS is one of them. It is the best financially apparently but there are a few things I need to know. Hopefully y'all can help me. Thanks a lot !
1) Does the white version attract dirt easily and if so is it easy to wipe it off? I know I can just get a case for it but since on the front there is a large area under the capacitive buttons and Im gonna touch that area a lot so I want to know. (Mini rant: why does it have so many visible seams, make the phone look a tard cheap)
2) How is the yellow screen issue? Has it been improved/ fixed? If I have it do you reckon it's gonna be easy to have Sony fixed it? I live in Australia btw
3) Battery life? I saw a lot of people having issues with the ICS update. My normal usage is 2-3 hours checking social networking sites, web-browsing, 2-3 hours of music, probably 15 minutes of games. Do you reckon if it's gonna be enough to last me?
4) Does this phone have any issue with getting coverage? In my house the coverage is terrible for most carriers. I had an HTC sensation and my mom has an s2 and they seem to not be able to hold on to signal any long.
5) So what do the colours look like w/out the Mobile Bravia Engine? I reckon I wont turn it on to preserve battery but I want to know how much it's gonna affect the quality of the screen. And in so many videos the colours do look a bit washed out...
6) How's the GPS? I dont drive but I use apps that use GPS.
That's all. Thanks again

1) I have the white one. It does attract a quite high quantity of dirt. The back is easy to clean. Just use a smooth humid cloth on it. For the lens, it's easier to clean it removing the back cover. The Xperia Logo on the bottom, and on the Camera, HDMI and USB logos on the sides also get dirty quite easily. The dust enters the little "depression" and get stuck in there. If someone knows a good way to clean this, please let me know.
2)It's been quite a long time since the start of the production. Until batch 14, almost all devices had it, on batches 15 and 16 it almost has gone. We must be on batches 30 or 40 by now, so no need to worry.
3)I think it's enough for me, and should be enough for you. Check the battery thread, and look at my posts to see my results.
4)Well, my carrier sucks for that. I badly can enter a corridor on my school without loosing signal. But I also had this with my old X10 MP. I think the coverage is good (not so good now, as I'm using Turkey FW, with a different baseband, but it doesn't make it unusable)
5)I always kept it on, so I can't tell the difference, really. Most people seems to have problems since the first ICS update (I also have this problem, but the screen is still awesome)
6)GPS for that is good for me. I also don't drive (heck, I'm 15 years old), but it is really accurate (with internet connection it's even better, as it have A-GPS)
Hope I helped.

Thanks for the reply.
About the batches, do you know how to check what batch it is? Since in Australia the Xperia S doesnt sell very well (I know it since Im working for a phone company now), so I reckon there are a lot of old stock sticking around.
And what is the problem you're talking about? Sorry I should have done my research but Im dong my assignment now and the threads are HUGE
Thanks again !

The only way I know is to open the back cover of the phone. On it, there is white sticker with info about the phone. On the right side, there is the phone model (LT26i), another info and something like this, 12Wxx, where xx is the batch, W is week and 12 is year. Mine is W10, so I have the yellow spot. Sadly can't trade as Sony Brazil is horrible.
The problem, I meant is that the Bravia Engine isn't working for most on the ICS update.
No more inputs from anyone?

Hey there,
1. I have the black xps, my friend owns the white version. It does attract quite a bit of dirt but using a case should solve the problem. (recommend nillkin hard case)
2. Yellow screen issue - my first xps had the defect, returned it to the service centre within a week of purchase and got a replacement in 2 weeks. The batch I now have is 12w16. So if it's possible for you to find out the production batch, I recommend you get anything beyond w14.
3. Battery life - immensely dropped after the ics update. Gb battery life was amazing (I'm referring to stock firmware). The issue is due to the phone unable to get enough deep sleep when the screen is off. (culprits being - alarm manager and power saver app, they keep restarting). On stock ics, with 3G constantly on, Wifi for a few hours, display on for about 3 hours, music for 30mins,auto sync on throughout - i get about 12-15 hours of battery life. With auto sync off, I get 3-4 hours more battery life.
4. About network signal etc. The phone doesn't have any issues. But if you're in a low coverage area, it's going to drain your battery even further. One bug I've noticed is that after a few hours or sometimes a day, my data connectivity just refuses to work, in spite of it showing active with the H/3G symbol. Only solution is a restart.
5. I keep my bravia engine off most of the time, honestly I can't really tell the difference cause the screen is one of the best in the market. Love the clarity.
6. Gps - no issues. Fast and accurate.
Hope this helped you.
Cheers!

So at the moment I have a couple of phones that I really want to buy and the XS is one of them. It is the best financially apparently but there are a few things I need to know. Hopefully y'all can help me. Thanks a lot !
1) Does the white version attract dirt easily and if so is it easy to wipe it off? I know I can just get a case for it but since on the front there is a large area under the capacitive buttons and Im gonna touch that area a lot so I want to know. (Mini rant: why does it have so many visible seams, make the phone look a tard cheap)
2) How is the yellow screen issue? Has it been improved/ fixed? If I have it do you reckon it's gonna be easy to have Sony fixed it? I live in Australia btw
3) Battery life? I saw a lot of people having issues with the ICS update. My normal usage is 2-3 hours checking social networking sites, web-browsing, 2-3 hours of music, probably 15 minutes of games. Do you reckon if it's gonna be enough to last me?
4) Does this phone have any issue with getting coverage? In my house the coverage is terrible for most carriers. I had an HTC sensation and my mom has an s2 and they seem to not be able to hold on to signal any long.
5) So what do the colours look like w/out the Mobile Bravia Engine? I reckon I wont turn it on to preserve battery but I want to know how much it's gonna affect the quality of the screen. And in so many videos the colours do look a bit washed out...
6) How's the GPS? I dont drive but I use apps that use GPS.
That's all. Thanks again

1. I used to own a XS before upgrade to the Acro S. A white one to be exact. I used a case all the time so there was little dirt to be worry about. I'm sure you'll feel the same. The 3 touch buttons on the front was horrid though.
2. If you buy a brand new one around this time, I doubt you will ever encounter this issue.
3. Battery do fine for me. It's about 3 hours of screen time, not very impressive but not bad at all.
4. Coverage is good. I've ever lost any signal.
5. You'll see a bit different in color, less vivid to be exact but you'll get used to it in tme.
6.GPS is fast and accurate.
Hope this help.
1)I have the older batch, so am having a yellow tint. Will send it for repair when I do have the time. As long as the bootloader is unlocked sony will gladly repaired it for you.
2)sony has said that bravia engine dont impact battery life, so u don't really need to turn it down
3)GPS is really really good, even without A-GPS( data off). Lock into position in seconds!. Must be the whole glonass thing,as other droids I use with data off,will need some time to few minutes to find me.
4)battery life,well as bad as most droids, 5 hours of screen time would drain it almost flat. But fast charging work as advertise, so plug it iN whenever possible,30 minits of charging could get it up around 50%.
5) call signal are really good, well at least I can comform it's better than samsung note,gio & s2.

[Q] Signal loss - Death Grip

Alright, I read the review on this phone and, after having the GalaxyS 1, I thought trying an HTC would be a great idea as my GS1 had extreme screen burn in; which led me to opt for an HTC instead of GS2 - the cheaper alternative of course.
I was pretty happy with this phone. Somewhat smaller than what I expected, though it runs fairly well with ICS and HTC Sense loaded.
Now the ridiculous issue. This phone has a severe case of 'death grip'. I've had quite a couple of frustrating weeks trying to figure out what on earth was causing the signal to drop completely from 2 or 3 bars to dead, when picking the phone up to text.
Before I considered googling 'hand signal absorb htc', or similar keywords to that effect, I tested my theory by holding the phone at the top two edges and then in my palm again; in the same position both times. The result? 5 bars to two bars, or even in some cases one bar. The signal where I live isn't excellent, however it's not terrible either. With my GS1 having no issue with signal drops. Just holding the Desire X in the palm of my hand, under the table results in complete signal loss.
This is an absolute joke. I've missed really important phone calls and the majority of sms's arrive late due the lovely signal loss regain repetition, essentially causing the phone do not receive calls, even though, provided it does have 3 or so bars.
So, am I the only one here who has this issue, or for that matter; a faulty phone? Really Really disappointed.
I do have a signal drop problem as I already wrote on another post and nobody answer:
"I have a lot of signal drops on GSM/EDGE and also 3G/HDSPA? The signal is full but, the phone is in stand by, the signal drops and I loose calls. Does anyone have this problem?
Also I noticed when the phone switches from 3G to GSM/EDGE first I have a no signal period (couple of seconds)."
I also had this problem with an LG Optimus 2x when updated to Android 4.0.4.

Sounds like a faulty antenna. Either that or you have lead hands.
It should be a cheap fix at any local repair shop or free if you take it back to the shop for a replacement.

What I don't understand is, when i'm on an actual phone call, there's no issue with quality or signal loss. Sounds like the phone rom is preserving the antennas power in idle mode?
