Hey guys,
i have a question about the proximity sensor and the value of the adc.
Is it right, that this value shouldnt be higher than 50?
if i starting to put my hands over the front cam its rises above 10.000 and the display changes to green colour and the phone starts to vibrating, so i am worried about it?
further i have a uneven home button, so the left side stands out a little bit higher than the left side so i can feel it more.
if this would be the only problem, i wouldnt change, but what about the proximity sensor?

is there a way to calibrate the accelerometer, it is way too sensitive, sometimes when im holding the phone on my palm to read email/text/webpage it auto rotates because i tilted it a TINY little bit.
i downloaded the app gps status, it has this crosshair thing to see which way you are pointing the phone towards, and it should be dead center if it is laid flat on a flat surface, but its shifted towards bottom left a bit.
i'm wondering if anybody has this problem also.
Maybe your flat surface isn't entirely level.
Just noticed that when I'm on a call the screen does indeed go to sleep. However when I take the phone away from my ear it does not wake up. This is a pain for I have to hit the power button to hit the end call. Anyone else have this?
make sure ur screen protector isnt covering the sensor

My zagg hd protector has a little notch that shows the tiny circular sensor and its not covered. When looking closer I notice the tiny circular sensor is part of a larger rectangular sensor? This goes left to right. Not sure if this can be the issue since if I cover it the auto brightness does work.
Here are some photos of Nexus 10 with backcover removed, you can see the screen is fused inside a frame along with digitiser and gorilla glass, the screws you see is for holding the battery and have no effect on the extent of light bleed.
awesome pictures!
Hm.. Have you tried to turn on the tablet with open cover just to see of the light bleed is still there ?
So I wonder...does it just all snap together during the manufacturing process? If the only screws are for the battery then what is holding the screen assembly to the frame? I hope its not the frame itself causing all the problems...that could take Samsung while to fix if at all :/

i guess they are glued together
great photos
have you tried to press at some points to see if the lightbleed changes?
after some speculation i think the backlight on the N10s is set to high
i know that my old Samsung TV looked terrible when using max backlight.
as i dont have any N10 yet (picking it up on friday) im not sure if the brightness slider changes the backlight or the brightness(black level)?
my teory is that the backlight is set at max all the time and you only change the brightness.
thats plain WRONG!
thats why colors looks washed out when increasing the brightness
what you want is also a slider for the backlight
the brightness(black level) should ALLWAYS be the same
if you want a brighter display you should only change the backlight as the backlight doesnt affect colors/black level or gamma.
backlight only increase the white level.
you dont want to change your gamma right?
so hackers and kernel experts
find a way to change the backlight and most of the problems should be gone
i think
also you need to replace or add a slider with backlight setting instead of the brightness slider

I suspect a thin strip of double sided foam tape. Glue aren't typically used on screens as they create fumes which can haze the screen. Atleast not when we install touchscreens for ATM machines. Double sided tapes are easier to apply also. Same process as screen protectors where you have 3 layers with the center being the actual film. In this case center is the double sided tape. Peel one side, put it on the screen then peel off the other side to expose the other sticky side then lay the screen down on the glass. When its not on perfectly is when I suspect light bleed happens.
The huge problem is trying to remove it once its on. You can use heat to try to separate them. With ATM screens they're thicker so somewhat easier to pull them apart as you heat them but with newer phones or tablets they're so thin that if you do this they'll easily crack.
IMO if the light bleed is bugging you just exchange it rather than risk cracking the screen. Then you'll end up completely voiding your warranty exchange

Here's a complete tear down. There's no mention of any sketchiness in the way it's put together or components used.
Today we received and promptly disassembled the Google Nexus 10. In usual fashion we’ll release the take apart video next week, but wanted to go ahead and post the preliminary take apart steps and photos. The model we’ve taken apart is the 16GB Wi-FI model. Model # GT-P8110.
One thing that struck us about this disassembly was the complete ease of taking this tablet apart. Whereas Apple seems to be making it more and more difficult to repair devices by combining parts and using as much glue as possible, Google seems to be taking the complete opposite approach. The end result is a device that is extremely repairable. Go Google!
Another interesting note is how many of the components in the device are manufactured by Samsung. It appears that the battery, processor, and flash memory are all made by Samsung. Is this Google’s way of capitalizing on the drift between Apple and Samsung?
That’s it. The Nexus 10 display and digitizer are fused together, so that is where the take apart ends.

that cable that says "GT-P8110" is very interesting. Might help with Samsung support reps in trying to identify what the device is

Edit: Hmm, just looked at my N10 box and it has the number as well; not sure how I missed that before.

its usually the back light led whose brightness is changed thats y u save battery life when u reduce brightness, what ur talking about is the contrast and thats fixed on the tablet, brightness being led light intensity and contrast being each pixel allowing amount of light through it
ok time to get this tablet perfect
i have some slight lightbleed at the bottom right corner as many has.
if i press at the back of the screen at the right corner i can clearly see that the lightbleed gets worse.
so the conclusion is that is has something to do with uneven pressure at the screen when you can affect it with pressure from the back.
i report back how it went and if i found some solution
A little bit off topic here, in regards to thermal throttling, do you think it would be possible to fit a small blower some where up top where the cpu/gpu is located?
Something like this (16mmx16mmx4.5mm):
http://www.digikey.com/scripts/dkse...ewproducts=0&ptm=0&fid=0&quantity=0&PV46=5197
It would need to be hooked up to 5V, some where like the USB or HDMI port connections on the inside or on the board.
It looks like there is a small hole underneath the camera in the lid that could act as an exhaust, a very restricted one, and the usb/hdmi/3.5mm ports may help intake and exhaust too.
For anyone who is interested, here is my method for fixing the black unresponsive screen during a call.
Like most of you reading this message I had the dreaded black screen during a phone call, which makes it impossible to end the call or dial numbers for automated systems. A lot of suggestions and fixes included blowing into the upper right corner of the phone or into the ear piece. This doesn't work (or it didn't for me) because the proximity sensor which you are allegedly blowing dust off of is pretty well sealed against the outside world. I'm on firmware 1314, which is supposed to have fixed the issue, but did not.
What did work every time was to pinch the phone front to back at the upper right corner right around where the proximity sensor was. I actually later found out you could pinch the phone anywhere in the upper half and the screen would light up.
I opened up the phone, saw that the proximity sensor just kind of flaps freely with a metal back that touches what i think is a grounding plate on the frame. When you pinch the phone it shorts this circuit and makes the proximity sensor behave properly. To make the contact better I cut a piece of aluminum foil, folded it up a couple of times, and wedged it behind the proximity sensor. Put the phone back together, made a call, and voila - screen on away from my face, off when sensor is covered.
Here is a picture of what the proximity sensor looks like on the pcb. I just wedged the foil behind the circled piece and replaced everything.

This absolutely works for me, but YMMV. I used the youtube video from le55ons for disassembly instructions. It's fantastic.
Excellent work. Subscribing in case I get this issue in the future

Do you have a screen protector installed. I did and it covered the proximity sensor, which gave me issues, took it off, no issues

I didn't have a screen protector on, but i can see how it would cause a problem if it covered the sensor. Now that it's working properly I can see how sensitive it is. If i hover my finger an inch over the sensor, the screen will go dark.
hi guys,,,
if NO iris scanner so, what is the sensor which located under the speaker griller directly??
Proximity sensor or are you referring to the camera. Lol
No No,,
I mean the sensor under directly the speaker grill NOT beside it... look at phone again
Hmmm don't see any other sensors under the front speaker and went through quite a few pics. Maybe some of the guys with devices from WMC could give more information.
I see no sensor under the front speaker. I see the camera and proximity sensor to the left and the led to the right. That's it.

Zoom in the picture and see !!
I hope this support my words...zoom to the end
Relax dude, the picture you provided doesn't even show this supposed sensor you're yelling about.
Plz zoom and put your glass on your eyes before
What about you at this?
I think that's an old render. I don't see that sensor on the actual G5. Probably an old placement of the led. It's now located to the right of the speaker.
But this is a leak and not the version that was presented in Barcelona. So whoever posted those pics could've done anything to them. Look at the other pics and reviews around the net and such sensor is not present elsewhere.
So,,why the bezel from top is very thick in size?!
Not even sure what you want to hear more than what's been already said. Check the images of actual phone not some leak. Plenty of videos are available too. If you can show me another picture with this sensor from the actual device then we can get into discussion. But for now just rest and wait for the device to be available if you're so concerned about this non existent sensor
There's no sensor.
LG has always had somewhat large upper and lower bezels. I can understand the top, seeing as it houses the camera, speaker, led, and sensor but the bottom seems large for no reason other than to slap their logo on it. The bottom is almost twice as big as the top on the G4.
Yes,iam so angry with the upper thick bezel and no reson for it at all

I'd actually much prefer they put the onscreen navigation buttons on the lower bezel so there is a reason it takes up so much space, plus it'll free up a half inch of screen space.
