say nothing about wifi chip. still know nothing about BT
Thanks! I wish they had told us what wireless chip it is.
BT chip is sort of meaningless. Look for the BT antenna. Without that, it does not matter if it has a BT chip of not.
Probably the same antenna as the NC.

Some will find it not meaningless. Sure for some things it is not useful, but it still allowed the ability to pair it with a wireless keyboard and with wii remotes for retro gaming. I believe some used bluetooth to connect gps device for cars and such so it is not a total loss.
*not disagreeing that antenna is important but it would be nice to know if any bt support will come.
My understanding was that without an antenna - the BT signal will not leave the NT enclosure, much less reach a wireless device next to it.
Would be glad to know I am wrong on this - but I don't think I am.

If it lacks the antenna but has the chip, might be possible to swap out a NC antenna.

Or make one. A little dipole isn't much more than a cat hair. Usually getting on the board is the challenge.
Here is a link to a BT antenna datasheet:
http://www.auden.com.tw/TRC/tw/product/pdf/41.pdf
Theye are easy to come by, very generic, and very inexpensive - but surface mount technology is very hard to add after the fact.
At the very least - hopefully the NT has the unpopulated lands for one.

Perhaps I am wrong but I didn't believe the NC had an antenna and that was why the range was so short, ie ~foot max.
after searching lots of threads it looks like nc shared the same antenna as wifi. there is no dedicated antenna for bluetooth though in NC, so either it is sharing it or it's non-existant.
That has to be an easy one for someone here to answer - did the NC have a BT antenna?
I thought it did...

It's a lousy teardown compared to the one for the KF. Half of it is devoted to meaningless appearance comparisons, and none of the PCB parts are shown in detail.
Anyway, battery spec is same as the NC (3.7V, 4Ah), and is less than the KF (3.7V, 4.4Ah). Interesting that cited battery life is longer than both the KF and the older NC, especially given the NT's x2 RAM. Either somebody is being optimistic, which is likely, or the KF's custom UI sucks both speed and power.
The Bluetooth situation looks to be the same as the NC and KF, even if there isn't a close-up of the chip involved. There's a single connector for the wifi antenna pigtail. The short of it is that BT will probably the work same as the NC, ie close-range only since no BT antenna.

The Nook Color's layout of the wifi module is almost identical (below). The ZDNet's NC teardown was more detailed, but didn't remove the heat shielding for the money shot.
Thank you! Those pictures help a lot. That last one is an excellent picture.
Thanks for the bluetooth info guys , here is the spec sheet of the screen but it says is TFT not IPS or I am wrong http://lcd.eechain.com/datasheet_detail.asp?bg_key=E1&sk_nub=LD070WS2-SL02

IPS is a type of TFT panel
Edit: IPS is not a type of TFT
IPS from wiki:
In-Plane Switching was developed by Hitachi Ltd. in 1996 to improve on the poor viewing angle and the poor color reproduction of TN panels at that time.[6] Its name comes from the main difference from TN panels, that the crystal molecules move parallel to the panel plane instead of perpendicular to it. This change reduces the amount of light scattering in the matrix, which gives IPS its characteristic wide viewing angles and good color reproduction.[7]
Initial iterations of IPS technology were plagued by slow response time and a low contrast ratio but later evolutions have made marked improvements to these shortcomings. Because of its wide viewing angle and accurate color reproduction (with almost no off-angle color shift), IPS is widely employed in high-end monitors aimed at professional graphic artists, although with the recent fall in price it has been seen in the mainstream market as well.
TFT from wiki :
Thin film transistor liquid crystal display (TFT-LCD) is a variant of liquid crystal display (LCD) which uses thin-film transistor (TFT) technology to improve image quality (e.g., addressability, contrast). TFT LCD is one type of Active matrix LCD, though all LCD-screens are based on TFT active matrix addressing. TFT LCDs are used in television sets, computer monitors, mobile phones, handheld video game systems, personal digital assistants, navigation systems, projectors, etc.
According to the Engadgit review--the only one to have a standardized run-down test--the NT's battery life is indeed significantly better than the KF, despite a smaller battery:
Barnes & Noble Nook Tablet - 8:20
Amazon Kindle Fire - 7:42
I'm revising my opinion to say that it's likely due to NT's better hardware design (improved from the old NC), even with x2 RAM and x2 flash storage.
http://www.engadget.com/2011/11/21/barnes-and-noble-nook-tablet-review/#continued
I've been hammering away on my NT all day and still have over 85% battery life. This thing lasts a long time, but so did the battery on the NC.
I would be willing to say that most of the perceived battery life difference is due to differences in the display hardware.
Everything else is just too close, hardware-wise. Ram takes nothing compared to the display.

Email I sent to VIP escalations asking if NFC was built into the chip and night vision camera.
I don't think I'm going to miss the kickstand too much
Might just be me, but I swear the layout on the screen looks so odd, like the app/icons are adjusted weird or however you'd like to word it...
Other then that, it looks great!!
I think it looks good but I wish it had a kickstand. I'll getting it regardless. Can't wait till Summer! Hopefully they'll give us more of a demo!
I didn't think the kickstand would be for me until I started propping it up on my desk while doing work. It was easier to pick up phone calls via bluetooth while looking at it. I really want to see how the camera shots look and what kind of lens they are using. I think the camera bezel is huge and unnecessary but whatever.
What is the shell/casing made out of?
There was a kickstand accessory for the View, and i wanna say the guy said there is one for the 3D too.
The demo from drdrewdown is awesome. This phone is totally badass.. you can completely shut 3d off if you like... they said display looks much better than the original EVO.
My only concern is battery life... but I htink I'll begetting this phone.
Yeah, whats up with the lack of a kickstand? BSOD mentioned it still has one, but I do not see it. He also mentioned NFC, but I've not seen that mentioned anywhere else yet either.
Looks good I thing they should have gone more plain style like the iPhone 4 tho(look), I'll miss the kickstands, I hope the video quality is better then my current evo, this is what the nexus s should be ha ha, definetely going to get it tho

That's because of the higher resolution screen
BSOD stated the NFC but who knows if it's included in the chip but not enabled. Also I could care less for 3D since the only thing I would be able to play it back on is the Evo. At least now people won't ask you if you have an iPhone when they see that huge camera bezel in the back.
I can imagine people selling screen protectors for the back and the front.
I'll miss the kickstand a lot. I love propping up my phone since i keep it naked and want to minimize scratching the camera lens.
So does this have the adreno GPU?
The one thing that BSOD mentioned that I was really excited about was WiMax+LTE. Unfortunately, I didn't see anything about that mentioned during the liveblog on AC.
It's an awesome phone, no doubt about that, but I'm definitely not as excited about it as I was before. With the way things are going here in San Diego, it seems pretty much pointless to pick up a new phone that only has 3G/WiMax, as it doesn't look like we'll get WiMax anytime soon.
When is this phone scheduled for release or is it unknown ATM?
Sent from my PC36100 using Tapatalk
So about those facts BSOD posted, which I said were incorrect.....
The phone is sick, but the EVO View truly surprised me. It's awesome. Anyway, adios.
looks kinda less sleek then the original evo to me...No kickstand is huge for me I use that like 100 times a day at least lol...Loving the internal specs tho wow that phone is a beast...damn decisions decisions lol

Just sometime in the summer.. No specific month unfortunately.
My guess is around when the original Evo was released.
I think I am sticking with my launch day EVO. Not really impressed by the EVO 3D. EVO View seems kind of useless.
Ever thought of a pad Without bezel border? Maybe that is why Acer and Apple's pad use such high resolution. They Fill the entire surface screen with Pixels!
The Ideal is to have Virtual bezel that will only go full screen when watching movies or dynamic bezel borders that depends on programs or environment.
just thought of it and think it's a good idea...
a) where would you put your hand when holding the device?
b) The transformer has a higher resolution than the iPad and >= any tablet that acer produces, so I don't have a clue what you are talking about there.
1) still has Bezel in main screen. only when watching movies the bezel will disappear. and u can still hold it, but won't effect it. That is what i mean by Dynamic bezel.
2) the new resolution will be 1920X1200, that is extreme packed density. So bigger area will result better yield in display and a seamless border. Like the new High end LED TV
Just a Thought, and thought it will be Different.
the resolution for the ACER Tergra 3 confirmed to have 1920x1200

I believe he's referring to the iPad 3 and Acer's upcoming 2012 tablet (that indeed will have 1920 x 1200 resolution): http://androidcommunity.com/acer-iconia-tab-a700-sends-photos-from-russia-with-love-20111229/
I'm not sure exactly what he wants out of a "virtual" bezel, but I'm pretty confident the trend will be towards smaller bezels.
I wonder if Tegra3 is powerfull enough for such resolution... The resolution is quite nice though - not need to worry about HDMI output because it's the same as your TV/LCD (apart from more pixels in height) etc.
1) I hope if they can add 2GB RAM to support window$ 8 and higher!
2) 3D screen

Virtual bezel would be interesting. But it would only work with an AMOLED screen. LCD screens when "black" draw too much power. Edge to edge display that has a 1/2 inch virtual bezel that could be controlled by the user...pretty crazy idea.
Do not want virtual bezel.
I have large, meaty hands. My pads wrap around the devices I am carrying. Already I have problems with touching the screen when I don't mean to because of this. And I do not want to change the way I grip things because my grip, while very gentle (after 12+ years working with military grade electronics), is quite secure.
>where would you put your hand when holding the device?
This is a pet peeve of mine wrt tablets. Why must we grip it with the thumb (on the bezel)? It puts a lot of pressure on the thumb, which means faster hand fatigue. Why not have a built-in (removable) handgrip at the back? Like this below:

I am pretty much pleased with Prime's display, dont need it any bigger than current size. Bezel size is also not that big, but the dynamic bezel would be a good innovation, if done right.
What I would really want in next prime is :
- 3g or LTE of some sort
- Wi-fi Direct (I am not sure if it can be enabled by s/w fix)
- Stereo speakers
- IR sensor (I know it is oldschool, but I like this thing on Sony's tablet S)
- Bluetooth 4.0 (I really dont know why I want it)
I am not so worried about USB 3.0, as I believe Wi-Di is the way to go. If future cameras or SD cards comes with built in Wi-Di, it should be able to send the pictures directly to the tablet, for editing and sharing.
How do you place the tablet?
In the front car screen?
Dont you think thats too big and block your view?
Or you just lie it down on the front passenger seat? Then how do you see the screen? And thats dangerous!
Or will you mod your car, remove the car stereo, put the tablet there?
Or ask someone to hold it for you while you are driving?
Somehow, I must missed and overlooked the proper place to put this big tablet in a car for navigation. Hmmm ....
GPS isn't even working properly and you want to use it? Get a proper GPS navigation device, the Prime won't cut it.
I wouldn't dream about using a tablet as a GPS, and I don't think I could care less about the defect GPS in the TP thanks to that, but isn't this a rather wierd question.
A fast google search gives plenty of good answeres for safe tablet GPS usage:
http://www.google.se/search?ix=hcb&...w&biw=1920&bih=979&sei=hSEIT_33MIGMswajssiCDw

Exactly. It's either me driving and my wife navigating or the opposite. And it's really much more comfortable (and safer) than doing it myself with a 4 inches screen... Navfree and Navit work actually very well on my old Transformer...
Dude, can you not get a tablet mount for your windscreen? pretty sure youtube can provide videos for that.
That's what I intend to do...
Just buy a bluetooth gps and place it in the front of the window so it always get good signal, i know i will.
in fact a mount would look super cool if you had augmented reality running at the same time.
I hope there is no sarcasm to this thread. For just because you do not have a use for a GPS on a tablet doesn't mean it is the same for others.
im actually being genuine...one of the reasons i would buy android over apple is due to the navigation app. its got me out of a few sticky situations.
a tablet running gps or augmented reality via a tethered mobile (i figure thats how you would do it) whilst mounted to my windscreen would be awesome in my opinion.
dont be paranoid.
I'm going to get a headrest mount for my work truck b/c my middle console is the seat flipped down and it has a headrest. It will be the perfect length with my arm resting on the console (screen tilted toward me) to tap on the screen and it will be at a safe position that won't impair my driving. I don't use gps I use google maps all day every day, I go from customer to customer and that's just the way I do it. Never got into gps as I just don't need something telling me when to turn (I have a brain for that). I will do the same in my personal truck and also use it for audio payback sometimes through the car radios. I will also use it on long trips mounted to a headrest for my daughters to watch movies. I may have to make a mount, but I'll get it going the way I want some how. DIY's are on youtube also, creative use of velcro strips...
I actually used to use navigation on my xoom. I'd be messing around with my xoom while my brother drove. Then we'd get hungry and need to find out how to get to a restaurant. Its not absolutely necessary but everything on the tablet should work, just in case.

This unit is not directly connected to your GPS unit, and can therefore be used with a variety of different models. It draws power from your car cigarette lighter. It is great for GPS without external antenna connector.
That means your tablet will be receiving the boosted signal and you don't have to worry about its location.
When I'm alone I use a stand that has a bean bag bottom and sit it on the passenger seat facing me. Tablet-sized car mounts are too big to travel with. When I'm with someone, they're the navigator.
I was planning to use the TFP in my boat with charting software. Today I use an old Ipad and a car mount. Beats paying $3000+ for a garmin marine plotter.

I use Transformer (original) as GPS only when I have someone else in car to hold it or I'm the passenger. Well, mostly. Sometimes I just put it... on the floor (so it doesn't break when I have to use brakes) - I don't look at the screen then, only listen to the voice.
With a BT GPS unit I plan to use it. I have a special phone mount integrated into my cars dash and it uses a quick release dual t mount bracket & I already have the parts on order from eBay to make a dual t mount tablet mount & it sits off to the right of my center console next to my indash GPS with zero view obstruction & full tilt & swivel.

I bought Chinese ANT-208 FM radio amplifier from Aliexress. I have Klyde KD-7003 Mazda 3 head unit with RK3066 and TDA7706 radio IC.
I installed in my car and took a video. I tried it only in garage yet, on next week I can say more, but it works! In my garage the stations with week noisy signal get clear.
Sorry for the sound quality it's my phones mic
It would be interesting if you could open up the box to see what is inside. I'm wondering if this would do much more than say this one.
I think I need one of these, my radio signal is pathetic. Is that an Eonon unit? Is that the blue ANT wire from their wiring harness?
Also FYI Americans: Joying sells a ANT-208 for $14 if you don't want to wait for shipping from China.

No, this is a Klyde unit what Eonon resells as Eonon GA5151.
Yes you have to connect the power wire to the blue ANT wire.
Today when I drove to my workplace the signal was as bad as before. So this isn't seems a solution. I think not the signal strength is the problem, but the noise. :crying:
Nooo I had high hopes haha. Well my reception is really bad with two particular channels so hopefully this helps at least with them. Also starting to get antsy and considering taking the unit apart and checking if that foil is broken.
Crap. Unless I missed it, I don't have that extra blue ANT wire in my harness. All I can see in terms of loose wires is two "KEY 5V" wires.

Such amplifiers give limited results because they amplify RF noise too.
The biggest problem in cities is that so many radiofrequency devices exist nowdays, that lots of interference gets generated. Using a simple amplifier like this, most often amplifies interference signals too, and makes the tuner of your radio even more crazy.
I fitted the below device from Pumpkin. It sorted my radio and I had no problems mentioned in the post above.

For best results, the amplifier must be installed close to the antenna, otherwise noise is amplified and the desired signal be swamped under that noise.
This wont be the easiest path to improving reception but will yeild the best results.

Power injectors works well if you car antenna has built in antenna amplifier.
If your car antenna dont have amplifier then power injector will disappoint you.
I received an "ant-208" with my Joying HU. In testing it killed AM reception with no discernible improvement on FM. I dismantled to find what appears to be a legitimate RF amp with a 5v regulator and RF amplifier surface mount IC. See attched a jpg.

If you have a long antenna cable, it may help.
Otherwise, in general, an extra RF amlifier can only help if you have a problem in the system. The problem may be an antenna with an impedance problem or a not so good input amplifier (or noisy environment) in the receiver.
If your RF system already is good, you will probably only see extra problems such as problems with overdriving the input when there are strong signals present, and if your reciever is very good and have better noise properties than the amplifier, even worse reception.
In short, if an amplifier solves any problem depends on the environment.

If you have a long antenna cable, even more reason to place the amplifier at the antenna! Placing it at the opposite end will only serve to amplify noise, completely losing signals of interest in noise.
Regarding impedance mismatch, doubt the manufacturer had grossly got this wrong.
Not sure you understand signal to noise.
Note that the tuners in these units appear to suffer from poor selectivity AND sensitivity.

Note that the tuners in these units appear to suffer from poor selectivity AND sensitivity.

Of course the amplifier goes to the antenna side, if at all possible, for the reasons you just said (signal to noise).
About antenna mismatch, the car manufacturers antenna system may have a different impedance than what the (retrofitted) unit expects, and in that case an amplifier may be benifical.
And, yes, the combination of poor selectivity and sensitivity may mean that the amplifier messes thing up when there is a strong signal present, so the milage may wary even with the same system.

best thing I have tried, though its not the exact one in using. Got mine at autozone and can pick up st. Louis, No radio station in central IL but can't with factory antenna.
Hi guys,
Using an audio analyzer you can always see but obviously not hear these proportionately spaced audio spikes coming from the V60. It can also be measured using another device by bringing it closer to the V60. I'm attaching a couple of screenshots that show what I mean.
I've read that the second screen is wireless and about wireless payment or charging functions that could be playing a part in this.. I'm really not sure so I decided to ask if anyone else sees the same thing. It's the first time I've encountered this on any device so I'm pretty curious.

What format is the output ie bt, 24 bit toshlink?
With stereo speakers in a room you could hear that. With closed drivers ie headphones no.

This is the V60 internal mic picking it up. Default Android output/input (48000hz 24bit, I assume). I just open any free RTA analyzer (with good enough resolution) , and it picks it up. It's always on when the screen is on. it can be seen and measured with any device able to pick up above 18Khz (I used another iphone 7 with the built in mic). When the screen goes of it's gone, when only the fingerprint scanner is visible on the V60, theres only one spike visible around 18500hz. When the whole screen is on, I can see a mountain of spikes around 18500hz, evenly spaced. My guesses are it's either connected to the fingerprint scanner, wireless second display, wireless pay or charge functions. My LG V60 is the only device I've witnessed this with and Ive only measured this one device so I'm not sure if there's something wrong with mine or all V60s behave this way. Either way its interesting . The app in the photos is Sound Spectrum Pro, I like it because it has extremely wide resolution and you can zoom in on any frequency range.
Try disabling the fingerprint scanner...
I just disabled the fingerprint scanner and it's still showing. I made a video and I'll try attaching it here.
Youtube LG v60 18500hz evenly spaced sound spikes
Maybe from the power regulation? External interference? There's no negative portion to that wave pattern.

External interference can be pretty much ruled out at this point. I noticed the missing negative half. The evenly spaced spikes do shift in frequency once in a while but not very much, still in the 18600 18700hz range, than slowly shift back to just above 18500hz. They always stay evenly spaced, they maintain the same distance from each other. They are over 20db in amplitude and if I really zoom in, the tips seem so narrow that it doesn't look like just an analog signal.
It would really help to see if anyone else can turn on RTA audio analyzer on their V60 and find out if they see the same thing.

Hi I just noticed that when I attach the second screen on the v60 theres another spike that appears immediately preceding the others and goes away when the second screen is off. Perhaps this is where at least some of the spikes relate to. Still very curious

Poor circuit isolation.
Whatever the cause(s) with a stereo signal in open air listening area those spikes will be audible when those sound waves interact with the other audio frequencies to produce secondary waves in the audible range.
With sealed systems like headsets, buds etc few can hear them directly, but some can especially younger females.
Interesting things do happen when I bring it next to a plugged in guitar pickup. Even with airplane mode on, no wifi and screen closed. I guess I was hoping for it to be intentional rather than not.
