Optical In Display FP scanners have come a long way in terms of reliability and speed, but that circle at full brightness that lights up on the display will cause a noticable degradation on that area in the long term.
So to prevent it I share an image that you should put as the background in the Lock screen that matches the color of the part that lights up during unlocking

Afik, burn in occurs if the pixels are lit for too long at same color. As the screen over FOD lights up only during unlock, I guess it won't harm much. Also, there's anti burn in algo that acts on AOD. Amoled technology has come a long way now and preventions for these problems are implemented by default.

Hi Guys - great phone which I've had a week or so now. Upgraded from the first Galaxy S.
Now I must admit to having very good eyesight (sometimes wish I couldn't see finer details!) and..
On white / grey images (download the various screen test apps to have a look for yourself)
The screen, when on a low brightness, is "muddy" and demonstrates a few vertical darker lines on the screen with mine showing quite a prominent one in the bottom right heading up about half way up the screen.
This is mostly visible when the brightness is at a minimum (regardless of auto or the powersaving options)
When the brightness is turned up it is barely visible, if at all... looks fantastic..
But.. at this point I preferred the screen on the Galaxy S which, when dimmed was more vibrant and didn't have this "problem"
Hands up who can see what I see? Any darker lines visible on your white / grey backgrounds? a side effect of this new subpixel arrangement? totally normal? some pixels not as bright in a row hence darker lines?
What do you guys think?
Cheers, B

Could you take a pic or something?
ASAP yes (no camera ironically so will have to ask a colleague!)
hold menu and press power button for screenshot off the device.
Yeah, mine set to minimum brightness and has some line artifacts like when LCD supplied with low voltage. (low brightness setting)
Easily noticeable when displaying grey colors.
I'm also using Screen Filter app, setting brightness even lower, some black points around 0.3cm is exposed at night.
Not sure those points are affected by anti-scratch film though.
Hola
I can confirm that I see the same "line banding" effect when using the device with low brightness. Like others have mentioned I also use the free Screen Filter app to get even lower brightness levels especially when reading stuff in bed in the near dark.
I would think this is a side issue with having the Super AMOLED Plus type screen but I guess only a Samsung tech can confirm.

65" long exposure exposing some black spots.(digitally enhanced)
Lowest brightness + Highest brightness.
Wondering those spots are caused by screen protector or defective screen or limitation of current AMOLED's.
You can see there is some current leak.(It should be bezel-like black if it is ideally off)

Not sure I understand you cpu98!
Is there a consensus we all have this "problem" - i'm on the verge of taking it back for a refund and "monitoring things"
Anyone understand the tech / spoken to Samsung?

Not sure what those black spots are... is your camera messed up? There's spots on the right even off the phone...
Also yes, pure black for SAMOLED still produces SOME light, but it's almost indistinguishable to the human eye.
Take a picture of a dark grey image on low brightness and it should show the bands the best...

That spot off the phone is on the wall not defective cam. As you can see photos are taken at different angle. And it is visible in naked eye.
Yeah I like its screen very much. That black issues are no problem in real use.
I'm very satisfied.
Anyone else have issues with screen burn in?
I am having some. On the right hand side the bottom bar has burned into the screen creating a permanent shadow of the bottom bar from when I was using the tablet vertically It is extremely noticeable on dark grey backgrounds.
Anyone else have this happen?
This is grounds for a return yes?
IMO this is unacceptable.
IPS displays can suffer from image persistance. It's quite well documented. You can either run a color strobe or display a white screen for a while to try to release the electric charge built up in and around those pixels.

It's not burn-in in the traditional sense...it's usually solvable by the above methods...whereas old-school burn-in on crt tubes was permenant due to the technology.
Ill have to do some research on this. Any suggested articles on this particular topic?
Or advice on how to prevent it like optimal screen time usage etc?
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.
http://www.powerbookmedic.com/wordpress/2012/11/16/google-nexus-10-take-apart-first-look
that cable that says "GT-P8110" is very interesting. Might help with Samsung support reps in trying to identify what the device is
http://www.samsung.com/us/support/owners/product/GT-P8110HAEXAR
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.
I've noticed today that my second screen seems to get stuck at a brighter setting when the main screen is off. If I wake up the phone and put it back to sleep it will drop to the low brightness and look normal. I am rooted and on the stock debloted rom. Has anyone else experienced this?
Also another slightly related question, but is the second screen an actual hardware second screen or is it software just using part of a large display? I only ask because when in TWRP it shows everything as one image and I cannot see any line differentiating that there are 2 screens.
There brightness is governed by the light sensor. You might have too much light shining onto it so it gets stuck at the higher setting. It's very sensitive so even moving it a few inches away from a nearby lamp might help.
The second screen is just part of a single LCD panel and it's the software that displays different stuff on it. That's why TWRP looks the way it looks on it.
Is there a way to manually adjust the 2nd screen brightness? At work my 2nd screen is so dim that i can barely even see my notifications, which is the point of the 2nd screen lol.

Hello,
Never had a phone with Always on feature so I would like to ask if is a normal behavior to see for a few seconds a clock image retention from AOD when the phone is unlocked.
I have LG V30 H930 EU unlocked model.
Been using a H932 with AOD since day one and have never seen any image retention issues from it's use.
It's not very visible, you have to look very closely and perhaps also have some specific colored wallpaper. It lasts only 2-3secs and then slowly disappears. AOD needs to be on a screen for at least 30-60mins I think.

But the AOD constantly moves.
As previously stated, the AOD on the V30 is not a static image, but a dynamic image, (it rotates to several locations on the screen at a certain interval). That should preclude it from issues involving image burn-in or retention.
Having said this, there is an app on the Play Store that Samsung owners use to combat burn-in on their OLED equipped phones. I don't remember what it's called, but you should be able to do a search by topic. The other thing I would recommend is avoiding having the AOD on it's bright setting. Its a bit too much, even in bright daylight, and it does increase the chance of image retention, IMO.
Bright setting is off, but the brightness of AOD at least on my end is dynamic and depends on the light sensor. This "bright setting" to my eyes do almost nothing.
Ok nevermind, probably I'm just nitpicking... I appears to be "visible" only on a pinkish part of the wallpaper. It's one of the default.
I have (what I consider) an annoying slow, fade to black when I turn off the screen. Perhaps your "retention" is the same, slow change of state for the screen?
Maybe we can call it this way. I'm coming from LG G4 IPS screen which is changing such things instantly obviously and I don't know what is "normal" for OLEDs. As i said, clock number from AOD after unlocking has its footprint for a moment on a wallpaper, slowly disappears.
The screen is otherwise pretty good if I cosider some horrible issues reported here or on reddit.
But still apart from this "retention" issue I found 2 more, but basically small issues described here:
https://forum.xda-developers.com/showpost.php?p=75657168&postcount=670
so don't know what to do.
I'm still within 14 days return/replace period, but I'm worried about worse screen since this is still a lottery.
Not sure what is your issue. Turning off the screen is doing fine. Just one quick "animation" and everything is off.
