I have had my nexus 7 for around 3 months now and have noticed that there appears to be a frozen image of the white elements of my home scree that are slightly but permanently visible. It is quite faint but I have noticed that things like the digital clock, and the white notifications are always visible. Sometimes even with the chrome Web browser get stuck being visible on the home scree. Is this a problem that others have and is there a way to fix this?
Thanks
does it appear while taking a screenshot? if not, its the pixels burnt into the display if you left the screen on the same picture for too long.

Hi,
I wonder if anyone else has noticed this in the blackstone; I can see a grid of dots all over the screen when it's turned on. Ok, you have to look closely, but it's a bit annoying. I can see the dots better when I have a white or green background. For example, going to Start -> Programs I see the dots in the space between the icons.
I know the dots are from the 'resistive' layer, the dots are the sensors of the touchscreen... but they become visible and appear as small green dots perfectly aligned. I don't see them all the time, only when I have a white background or looking with a certain angle.
Should I be concerned? Could it be a problem with my screen?
Thanks!
Sounds a bit strange to me, the only time I can see the dots/grid is in bright sunlight. Then they look like small pin points in plastic.
i've never noticed that on mine...
That is normal, those are touch sensors for the screen. They allow the screen to recognise a touch.

Agree, but I had other PDAs before and never seen the dots when the screen is turned on. I don't care about the dots being visible when I'm under a bright light; my point is that I can see the dots when the screen is turned on, no matter under what kind of light. When I have a white backround, it looks like there's dust on the screen. If I look closely, I can see the dots in green colour, as a result of the reflectied light from the screen. I know they are the touch sensors, but it seems no one else can see them--
Any idea?
Thanks!
it is indeed normal especially under bright sunlight. However if you insist that you can see them when you switvh your device on, no matter the external light conditions, there might be something wrong with the screen. Have you seen other HD phones recently? Do you see the same dots there when they're switched on?

I haven't had the chance to see another HD; I've looked at a Diamond and Cruise, the dots are NOT there. I've tried to take a picture, but seems impossible to see the points in a picture (at least for the N95's camera).
I found an old tread talking about old PDAs that had the same issue, maybe they explain the issue better: http://forum.brighthand.com/showthread.php?t=207321
I'm not sure if I should send the HD to the service. Anyone knows how the 'worlwide warranty' works? I sent an email using htc.com site, but they don't respond.
Thanks!
Any advice on this matter...?
I don't know about colored dots, but every pocket pc I've ever owned had the dot grid visible in sunlight, it is normal, they should be clear dots though.
Alright, so I have a nexus 4. I don't know how long this issue has been around, since only now am I noticing it. After having a fairly high contrast image on the screen for a few seconds, such as the facebook status bar, if I go to another app or the homescreen, sometimes I can see a faint outline of the image. It can occasionally get really bad, especially after the screen has been off for a while. Like I was watching a video on firefox, so I switched to landscape mode. The video couldn't go full screen and I had two grey bars on the side. I was shocked to clearly see the firefox navbar burnt into my screen. Thankfully all of it cleared up, but I'm wondering if anyone else has an image persistence issue. I'll try and get a picture once I can find a camera with decent exposure. Also, it seems that the sides of the screen, especially the right side, are brighter than the rest of the screen, also after the screen has been off for a while. Don't know if the two issues are correlated or not, but I think they are. I was using facebook and my phone crashed with a white screen with lines going through it, awful image persistence, and terrible bleed through. Held down the power button and there was the bleed through and image persistence, along with screen flicker that makes a CRT look entirely static. I'm wondering, what the hell is up with my phone? I haven't really done anything wrong to it, this just kind of happened.
Got a photo. Couldn't find the cable to connect my camera to my computer, so I had to take a photo of a photo, and for that it turned out alright. Don't know how well it will turn out on different displays, but trust me it's there. This is the icon in the top right corner of the facebook application. When I swipe from the right to the left to see who's available for chat, I can see an outline of the icon that was there before.
I've noticed the persistence too at times, like a ghost image - CRT with a static image on too long, so if there was any doubt, it's not just you
I've had the same problem several times before. I just had it again, quite prominent! It stays for a few seconds, and then fades off to nothing.....Quite worried? :S
Hi guys,
I have noticed in the dark when using my note 3 in the settings menu the bottom portion of my screen seems to be grey not black. At first I thought maybe this was a software issue so I took a screen shot and zoomed in. When viewing the photo zoomed in the entire screen is grey ish with lines (normal lines had on all amoled screens) When moving the image the greyness does not move which to me says its the screen. However! When using a pixel tester and putting a pure black picture up the screen is perfectly black.
Ideas or thoughts?

That's the way Touchwiz and Gingerbread was originally designed and Samsung kept it this way. This is completely normal and is the software. It's not an issue. It is the same way on my Note 3,Note 2 and Galaxy S II.

Open a completely black image. Download a solid black JPG from google as your test. Do the same thing with a completely white image.
Look at those images in full screen mode.
If there is burn in (which CAN happen on an LED screen, though it's actually pixel fading rather than burn in) you should be able to notice it with this test.
If you see fading in the white image, or general non-uniformity in the brightness, it's a sign of fading. (burn in)
If you see a ghost image in the black image, then something is wrong. It means the screen is lighting up when it shouldn't be.
You should not be able to see a residual image on a black screen like you used to with an old CRT computer monitor. The burn is doesn't work that way. What happens is the pixels lose some of their brightness over time. It's subtle, and if the screen is fading uniformly you probably won't notice. But when 1 spot isn't fading, you notice it quickly. This is most commonly seen with the status bar. If it's always black and the area right beneath it is always colored, then the black status bar wont' fade and the rest of the screen will.

Thanks Sir,
actually it was lcd problem
I had my s8 yesterday! the phone is okay (I had many Lg/ galaxy phones) but I noticed the chat bubbles of messenger are staying for a while when I open a grey wallpaper (white lines and borders of the chat bubbles) I know the difference between screen burn and screen retention! is this normal ?? it only stays for 3-to-5 seconds then it disappears. should I be concerned? the retention is only noticeable when I open a full grey wallpaper. however, the alwasy on display can be fairly noticeable when I check the same wallpaper!
Is anyone experiencing this?
