Hello,
I was using my TFP today and all of a sudden the screen has gone mad. All blacks are white all color is gone. It sort of looks like all the colors have been inverted and then the contrast went to 0 with the brightness at 100x. (where the screen looks like this on any brightness) Anyone seen this before and know how to fix it?
It's not in inverted color mode to help color blinded people since most text is not even visible.
Please look at the picture http://img51.imageshack.us/img51/3360/img4165kv.jpg.
It shows my desktop wallpaper on SGS1 on the left and SGS2 on the right. The top left part of the wallpaper looks fine on SGS1 but it turns ugly dark green on SGS2. Please notice that the other colors (pink, light green etc) look very similar on both devices. I set the brightness on both devices on equal level. My SGS2's screen displays like this only dark colours, bright colours are fine. Similar thing happens in AOSP/CM9/10 settings panel to dark grey gradients - it turns kinda dark green and ugly.
Here's another example: http://img23.imageshack.us/img23/4066/img4166a.jpg. AnTuTu background on the SGS1 (left) doesn't look so dark.
Am I the only one experiencing the issue? Do your devices display equally bad dark colours as mine? Could you post photos of your CM9/10 settings panel or AnTuTu's main screen?
I am kind of just curious about this, as I have searched the net and have found no one who has experienced the same problem.
I have a Blu Touch Book 7.0 plus, and plan on making do with it until the right phablet comes along at the right price. About a week ago I had it in my pocket as I helped to unload some heavier packages from a truck. It took some impact while in my pocket, I didn't think it took any meaningful impact. But then I turned on the screen, and everything seemed to have a blue tint. On closer examination - it didn't have a blue tint per se, but black was being displayed as blue; opaque black was opaque blue, semi-transparent blacks and darker grays and what not resulted in a blue tint. But whites and most colors displayed perfectly fine - i.e. for example, the Google home page looked completely normal. The display damage is evident even on boot, as soon as the manufacturer logo pops up before the bootanimation.
My workaround for the time being is to use a screen filter that places a semi-transparent white image over the screen, which gets rid of any hints of opaque black with about 48% transparency. It results in faint colors of course, but the colors are at least accurate with no blue tint, and the screen looks almost completely normal from the certain viewing anglea. Interestingly - the absence of opaque black seems to result in a lighter load for either the cpu or the gpu; previously the phone ran very smooth but if I had Dolphin (or another resource consuming app) open, and turned the screen off without pulling up my home page first, the screen would not always turn back on right away, either I would have to long press the power button or wait up to several seconds. Now, regardless of what I have open, I can toggle the screen on and off without lag.
So is this damage to the gpu? The screen itself? Does anybody suggest a better work-around?
Appreciate it.
Are you noticing that when you use Stock Gallery, Netflix, and YouTube apps, rendering a completely black picture or video doesn't show pure black. Rather it looks like a blotchy black. It bother me so much since this is an AMOLED screen and I know that when an OLED panel renders black it shuts off every pixel rendering black so a plain black image should turn off the screen completely. But in my case I see blotchy black screen and this is only noticeable when you're in a dark room. Please tell me you also experience this. Otherwise, can somebody explain why? Do I have a defective screen? Thanks!
Videos and pictures in lossy formats won't have a perfect color information, the system will try to interpret it the betst as it can, mostly resulting in the screen showing strange patterns instead of a plain black picture.
This app will create a lossless black picture, you shouldn't see any difference between screen on of off.

I don't see any light bleed for that. However, it's just weird because when I did a screenshot and open it on my stock gallery app, it again showed a blotchy black. But when I open in Google Photos, it is completely black. Also, watching this completely black video in YouTube also shows blotchy black. https://youtu.be/XIMLoLxmTDw

I don't think this is a screen issue. I've used Mate 10 pro for 2 months and haven't come across any issue. And I found the mate 10 pro screen is very solid. If you want to replace it, that would be very difficult.

Did you try it at minimum brightness in a dark room?
Edit:
I mean maximum brightness in a complete dark environment.
Out of a sudden today, I've experienced a yr yellowish tint over the general UI for white background apps like the setting page, chrome n Facebook. The white is ok in dark mode. I've disable eye comfort mode and also tried color adjustment etc... The boot screen white is also ok... I've recently updated to Android 12... Anyone e experiencing the same issue or have any solution to this? Thanks

Anyone experiencing this can try disable the chrome dynamic color gamut... It seems to work (under observation)
