Nexus 4 Screen Problem - Nexus 4 Q&A, Help & Troubleshooting

Anyone has dark spots that only show up in a specific spot and not always, mine shows up in dark colors like the lock screen, specially grey. I tried flashing other roms including stock images from google and still have the same problem

Vertical lines with certain shades of grey?

I'm seeing some backlight issues with certain shades of grey on my Nexus 4. It happens in certain places in the settings menu (near the bottom where it blends into grey) and even TWRP's grey background when backing up a rom. Franco's gamma settings help a lot, but the problem is still noticeable at higher brightness. Does anyone else have the same problem or am i being too picky? My iPod touch 4g had a horrendous problem like this where a certain shade of grey would show all these dark blotches on the screen. I figured it was due to the LCD/backlight.
Seeing this on P.A, TWRP and Stock rom.

I have the same thing but I'm just now noticing it.
Also, this may be related, whenever I flash PA and go back into twrp recovery, it takes unusually longer to boot into recovery and then I see these yellowish streaks/distortion going throughout the screen in recovery and it appears to carry over into the ROM when I system reboot.
It's happened several times, but it appears to be only when I flash PA and it goes away when I flash another ROM+kernel. I'm going to see if I can reproduce it and take a picture of it next time it happens. But after the obvious streaks went away, I noticed those gray lines, but if you look closely, there's horizontal lines too making a grid, though the vertical lines are more apparent
I feel your pain.

I also have this problem and many others. I have read many threads but no one really has the answer. I tried different Kernels and it helps but its still there.
I dont think we are being to picky, its just that we like things to be as perfect as possible, but there is no such thing.

I have had this issue from my first nexus 4, which I had issued an RMA request about this problem. My second n4 was fine and this is definitely a defect of the LCD screen.
I've spoken to a few people and checked their Nexus 4's and sure enough, they've all got it too. I think i was being too picky. It really isn't noticable unless i'm in a dark room and the brightness is high and i'm focusing on the screen. Day to day usage, i almost forget about it. It also helps that it only shows up on a certain grey colour.
Its just an effect mate, Ive seen it on everyones screenshot when they are showing there settings menu or something.

[Q] Background ghosting

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.

[REQ]SmearFix

Can anyone make an ultimate fix for galaxy s4 smearing?
Are you talking about the graphical smearing/tearing that happens when you, for example, scroll?
This is caused by the pixels. In AMOLED devices, when a pixel shows black, it is actually turned off. However, there is a delay when turning that pixel back on. So if pixels have to change from black to colored and vice versa (for example, scrolling through your app drawer if it has a black background), this graphical glitch occurs because of the delay from turning the pixels off and on.
Samsung has rectified this issue on their stock ROMs by eliminating true black, making the pixels always on. This will also negate the battery saving effects of AMOLED displays when showing black. This is the only way I know to fix the problem.
If you were referring to another "smearing" please elaborate and we may be able to help better.
I'm talking about that one that you said.. but in 3rd part apps in 4.3 stock android roms there isn't any fix ,apart Screen adjuster setting contrast -10, i wanted to know if someone can change blacks in very dark grey keeping the other colors , not changing all the colors setting contrast -10 or SmearFix app

True Blacks are Grey (ish)

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.
