Hey Guys,
I'm having a really weird problem with may Tab 3 7.0. I got it about four weeks ago and everything was fine until thursday. I used it normally, listened to some music and then let it lay around for a while. When I turned it on again, it seemed like the display was messed up. It now looks like 8bit graphics. I hope you know what I mean. Really pixelated, missing colors, hard edges instead of gradients and so on. Also it looks really bad and some parts of the display are flickering even when nothing moves or is animated. The color black is also gone, it looks really greenish when it is supposed to be black.
This is sadly throughout the whole device, meaning, also in the startup screen, in recovery, DL-mode and so one. I tried to flash some new firmwares, nothing changed.
So far I guess, it has to be some software issue because sometimes when I turn on the tablet, the graphics look normal for just a second until they change back to the ****ty looks.
Does anybody of you have an idea what might have caused this, or has an idea to solve this issue? Would be really great If you could help me out!
Greetings

Guys, I'm noticing i'm having this problem, where by the bottom bar for the windows today screen, is appearing everywhere, especially during volume adjust.
For example, i click volume button, it will bring me to the volume screen right? if i look very very carefully at the bottom, i can see a very opaque image of the bottom bar, even sometimes with the words "calendar" and "contacts" visible! a soft reset immediately solves this, but after a while the problem comes up again.
I've tried the following roms
Aztor
Dutty
Diamond rom
Swift SBL
all with this same issue. Is it a bug, or is it a hardware problem? I tried taking a screenshot and the screenshot does not show the opaque "ghost like" bottom bar with the words calendar and contacts.
I tried switching off Touch Flo 3D, and sometimes after a while, it appears again. It can be best seen when the screen is black (not off, just black) especially when volume adjusting.
Is it just me, hardware problem screen problem, or a rom bug that everyone has?
just to clarify again, despite it being visible to my eyes, SPB screenshot does not show this "ghost like" image, and it looks perfectly fine in the screenshot
I dont see that but I think it can be a sort of 'memory' thing of the lcd-screen.
Same problem here
Hi!
I have the same problem here...
the Ghosting comes after using the phone a lot so I think it might be because the phone heats up.
All the roms I tried have the problem so I think its an hardware issue.
Just keep your screen off for a while (not the phone) and I think it goes away.
Also TF3D has nothing to do with it...The problem happens with or without it on.
If anyone has a soln I'd love to hear it!
great to see that i'm not the only one. was worried sick that it was a hardware problem
Hi Baronic i've nothis more than a month back... see this thread..

also see this thread...

So you or me r not alone..
I used to be worried whether over next few days or weeks whether my screen will get worst, hence i used to keep screen very low brightness (with Spb shell)..
Over last 4-5weeks atleast there is no progress of the screen problem although it still persists..
Not finding a final answer, i've stopped bothering about it and just enjoy my diamond..
U r a senior member so, If u find an answer please dont forget to PM me..
Forgot to mention a tip... Keep brightness lowest and you'll never see it again.. (Although i like my screen to be brightly lit!!)
oh i didnt see those threads. primarily cuz i didnt know wat term to search for lol. if its a memory problem i think it can be fixed. will try and see how it goes, i'll experiment
Right!
I just noticed something really weird. I have 5 accounts set up for mail. All of these accounts have many mails in them.
Now, on the mail tab in Manila, when I switch between these accounts (so you see the swirling envelope animation) my screen flickers. And I do not mean just Manila, the entire screen... like the backlight is going on/off (well lower/higher, not really off).
This animation is the only place I've been able to find this issue. My other TP2 does not have this problem. Neither do the TP2's of the people I have talked to on IRC.
So there are two questions:
1) Is anybody else seeing this? (if so, are there other places you noticed?)
2) Anybody know what the problem may be?
3) WTF! (thats not a question)
I'd hate to have to RMA this baby.
I noticed flickering when playing solitaire. I initially put it down to the auto ambient backlight brightness adjustment but I turned that off as it just wasn't working. I still get the flicker in solitaire and it's noticeable when moving a card over some others.
After reading this post I checked my mail tab and yes I do get a flicker when moving between accounts. It's harder to spot because most of the touchflo screen is black. I haven't noticed it on anything else but that's probably because I'd dismissed flicker on other applications as down to the crappy auto-backlight adjustment.
To be clear, the flicker is a rapid dimming and brightning of the whole display.
Same here, didn't realized it until you mentioned it.
No big deal for me.

Had the same with the HD when the brighness was on full. Same on the TP2. On the HD issue it was put down to poor screen. Think its a common thing.
it seems to be similar to the technique Samsung is using with their LCD TV line... Dynamic Contrast. Basically it turns down backlighting to increase contrast between light and dark screens. I don't care for it on the Samsung TV's and I don't care for it on my TP2. But so far this is my only complaint, and it's a small one. I absolutely love this device (just got it today)
I have this issue. I guess its not normal otherwise your other TP2 would do it.
Ive also noticed it in google maps. When panning and it loads up the next image the entire screen gets dimmer.
Im going to send mine to HTC soon for a pink tinge on the screen. I will raise this with them.
I'm quite convinced that the effect was intended...
Try calibrating backlight with Lumos: http://forum.xda-developers.com/showthread.php?t=450318
It can drastically reduce the effect...
So in the last few days I've noticed something strange. Anytime I have a bright image like a white screen or the sepia or white backgrounds in Kindle, the entire screen dims and brightens randomly. Its an extremely small change, but it is noticeable. I don't have content adaptive brightness or auto brightness active, so I know its not that. I tried different bright levels and get the same result. If the screen is a dark image, like dark mode on Tapatalk, I can't see any flicker whatsoever. I have tried a clean install of PA 3.57 with AK SKL 256, and its still the same. It also doesn't seem to matter if I just picked the phone up or have been using it a while.
Does anybody have any ideas as to what's happening? Should I start looking for a new phone cause mine is dying, or is this normal somehow and I just never noticed, or could it even be an app specific thing?
Thanks for any help!!
PS: I just saw it flickering minutes ago on Kindle and Chrome (imdb website which has LOTS of white) but right now typing this post on Tapatalk I don't see any flicker, and as most of you know that's a white background.

I too have noticed this when using my phone on minimum brightness. I used since the last 21 days PA ROM, always the latest and AK SKL 256. I noticed it on websites with alot white on the screen. I do have content adaptive brightness enabled, and auto brightness disabled.
And please, just keep your phone till it's dead Mabey everyone has this but no1 has ever noticed this untill just now
So it seems to be getting worse. Now pretty much as soon as I open a white screen it starts flickering and seems to be dimming darker as well. I've been using PA, what are the odds its a ROM issue? Nobody else has reported it but I think I'm gonna flash to stock and see what happens.
Also, bump.
I "think" its fixed now. I flashed back to stock, had a totally clean phone, then flashed PA back and copied over just what I needed to the sdcard and I haven't seen the flicker come back. The clean flash made the vibration much stronger on the phone so I guess it's conceivable a screen problem was fixed too. I must've had something really messed up in there.......
So I've gotten Redmi Note 8t half a month ago or so.. and about the time I updated to MIUI 11 I've started experiencing this weird bug.. Any app or screen or page or icons from the home screen or buttons from apps that remain turned on for some time (literally anything longer than 15 seconds) kind of stay "etched" on my screen for some time (relatively equivalent to the time the relevant app/screen/page was turned on).
I have no idea why this is happening so any help would be massively appreciated. A photo of the problem attached.
Ps this bug appears on every darker screen, not just on home screen.

the images don't seem to be loading for me, but looking at your description it appears to be a burn-in problem.
I'd suggest you bring it to a service center to have it checked.

Thanks for your reply. Try opening them by clicking on the link and then tapping on "view full image" - it's the only way they'll load I've no idea why, today the whole xda website behaved very unresponsive for me, maybe they didn't upload properly.
Anyway I've just now googled "burn-in" (yep I'd never heard about this before) and from whar I've seen it seems pretty similar to my problem.
Although, in my case, the icons/buttons/keyboard letters that "etch" themselves into the screen after being used for some time do disappear after some time (usually dependant on the time those apps/icons/letters were shown/used on the main screen.
PS The thing is new, I've no idea how this could have happened.

I had this issue with a Moto G5, apparently it is not permanent, wich is nice, because when its permanent like in the case of amoled displays, the only real solucion is to replace the display. In this case to minimize it I downloaded a blue screen filter app and lowered the screen brightness to around 70 or less, btw this usually happens when you are watching bright stuff or when the phone is hot, also try to use dark mode whenever you can.
FOUND A SOLUTION
After tampering with many a setting, I found out that setting the colour temperature of the display in the stock settings of the phone to cool renders the burn-in almost completely invisible.

nice to see your problem has been solved!
some LCDs have screen retention when displaying certain colour temperatures.
also, seems like your attached photos are working again
Been using the phone for the last 12 hours and I noticed something towards the end of my use last night.
The screen seemed to become unresponsive. And when it would work it would start to make its own input when scrolling and opening any app or link my finger would drag over while scrolling.
Changed refresh rates, changed resolutions, even seen if the blue light filter was the issue. Nothing.
Almost seems like the screen drops frames when scrolling, like it gets caught on something.
New development. Fingerprint sensor doesn't respond at all and inputting a pattern is damn near impossible. Going to try removing the screen protector to see if that could also be the issue
Did a factory reset
Issue seems to be where the finger print scanner is
It's almost like a dead or unresponsive zone.
Sounds like a factory defect, better have it replaced if resetting didn't worked.
Small video showing when scrolling over the fingerprint reader, the screen almost loses input
Defect.
Samsung has been little help lol. They want me to send it in for repair instead of an exchange. They also said to just order a whole new one and return the one I have now except the black 128 is sold out

Sounds like Samsung support LOL...sorry you're having issues
Did you remove the factory installed screen protector? Maybe it's the cause of the issue
Return that pal, that doesn't sound good at all.

one of the first things i did to trouble shoot. still having the issue. sometimes the screen completely loses all touch registration and it doesnt even know im trying to swipe or push on things. just realized it did this also after tmobiles new software update.
im still waiting here to hear back from samsung on how they are going to fix this issue
The same thing happens to me. Pulling down the notification shade seems to be the only thing that still works. It seems to goose the phone and it starts working again.
Test using the *#0*# diagnostic menu and use the Touch test.
