LCD burn in (image persistence)

Hey all,
I am having troubles with the LCD on my touch diamond, i have had it for quite a while now.
In January this year, I started to notice that the soft button bar at the bottom of the screen was flickering, just the soft bar. I would turn off the screen for about half a day and it would go away, then it would happen again in a few days.
This happened for a few weeks, then it just stopped.
Now its back again, where I can see "Now Playing" faintly, as well as what is actually there ("Contacts"), but i don't have WMP open. and the whole bar flickers slightly. i just have to turn the screen of for a minute and it dissapears.
I only had WMP open for about 5 minutes..
I have the same issue. Here's what I did to (temporarily, I assume) fix the problem.
I made a white picture in MS Paint that was 640x480 pixels and put it on my phone, then set the screen to maximum brightness and left the screen on with that picture full screen. It got rid of the burnt in image.
I think the problem I had is that in my power settings, I had it to where the screen never turns off when plugged in. If I got a text message or e-mail after I plugged it in and went to bed, the screen would turn on and never turn off until morning. I've changed my power settings so even when plugged in, it doesn't stay on for more than a minute. I hope that fixes it.

I'm experiencing the same problem as well.. it come and goes and I've somehow learnt to ignore it. So far it just disappears after a few hours of use.
Hey its thr with many people, A quick remedy. Increase the brightness level to max....wait fr a few seconds thn put it back to normal. Wont prevent it permanently...but yes will hold it off for a while
Happens to my Diamond too. I am now trying different versions of HSPL to see if the problem is related to it.

lg urbane ok on dim screen shows dim display but when i touch it, it goes black

couple of weeks ago I noticed screen just goes black when trying to come out of dim mode. did factory reset by unpairing. I can re pair ok using the dim screen so all seems ok apart from the black display when in main display mode. ie I can still swipe etc to pair the phone even though there is no display, I just have to wait till screen goes dim to see what to do now. any suggestions . never tried to use laptop with cradle and watch so is there some sort of diagnostic programme using a laptop/pc. tried theatre mode etc and it vibrates but still no main display

Weirdest black screen issue, tried everything ....

Non rooted, T mobile branded 3 month old note 8. No water damange, no drops etc.
Using chrome one miniute, set the phone down to watch a movie on my tablet, picked up the phone to check messages and boom. Screen is off. The phone works, I can even answer calls because I know where the answer button is on the screen, haptic feedback works, all indicator lights work. The phone screen remains off.
Tried a soft reset (tried hard reset too the best I could being I cant see the screen) and the phone seems to reset based on the vibration and indicator light patters but the screen remains off. It's as if a physical connection between the screen and the brains of the phone has been severed. Literaraly the weirdest thing that has happened to me in a decade of Android phone ownership.
Googled all the black screen issues with these phones and most of them are resolved with just a soft reset... some said that the phone is in it's lowest dimmed state and go to a dark room and i'll see it faintly and then can increase brightness... no luck...
Has anyone experienced this?
I would say it's a warranty job, just tried turning my brightness to zero and you can still see the screen.
I did have a similar problem on an old note that had root and custom rom though but I had somehow set the volume rocker to control brightness and it had lowered itself to minimum in my pocket

Try pressing and holding Volume down and power button for 5 to 7 seconds to force power off, then try to boot to download mode Volume Down + Bixby + Power button and see if the download mode screen shows......if not then probably a bad screen.

Tried it......nothing.....warranty job it is.... Bummed to have some refurnished phone in exchange for a Brand new 900 dollar phone just a few months back?

Yeah that sucks, i can imagine..... i too hate the idea of refurbished units being swapped for warranty....bs, should be brand new unit!
Sent from my God Mode 8
so I had it replaced under warranty through T mobile. Refurb phone will come in today. One quesion. Should I let the Tmobile techs do the data/settings transfer from old phone to new one or just do everything myself from scratch (which will obviously take longer).
This happened to my phone twice for the past month or so. (both in Nougat and Oreo - Non rooted) Black screen but phone seems to be responding -- I can receive calls and notifications etc -- And force reboot doesn't fix it. I've also tried drainging the phone when it first happened to me but doesn't work. HOWEVER, it gets okay so randomly. Like I just left it for couple of hours and it just worked when I hit the power button.
I did tried bringing the device to Samsung but what they did is to just manually upgrade/reset the software in their end which I could have done in my part but I just let them do it. They told me to come back if it happens again which is kinda BS.
I can conveniently say this is a Hardware issue. I will wait for it to happen again on my phone and request for a replacement. Phone is 4 months old when it first happened.
I have the same issue with blank screen but phone is working.
It started couple of weeks after i dropped my phone on the ground. There is black dot on my screen and broken glass but phone was working ok and was still pretty usable. But then it started:
Display works fine but when i switch display of, lock the phone or display switched because of its timer it didn come switch on... But phone works, i can use it with blank (black) screen.
I had to do force restart so the display will turn on with samsung logo and booting screen, and keep on till another switch of.
I was trying every setting (but no hard reset) and then i found a little hack:
When you turn on the "Always On Display" (AOD) function you can let the screen switch off or do it manually, wait for 1-2 sec and always on display will come up to the screen. Then when you press home button or lock button screen will swtich on normally. YOu can type pin and use phone witch screen working. But when you try to unlock from "AOD" with your finger or your eyes it unlock but with screen black.
So i was using it like this. everytime you need to wait second untill AOD comes up, but it was working fine.
Problem nu 2 is that now it stop working, AOD is working but when i want to switch screen on from AOD it shows black screen and phone is working on blind.
So everytime after my screen goes black or to AOD i have to unlock the phone blindly and "Force restart" it and have to keep waiting until boot, and then have to never let phone to screen of.
Its not usuable.
¨
Now what do you think? Is it hardware problem or software problem? Because screen is working but randomly. The black dot of dead pixels on the screen is getting slightly bigger in time (about 1 year) but its like 1.5cm round. Maybe this cause the problem? And why hack with AOD was working for half a year and then stoped working? There wasnt any updates right before, but i tried to install some apps (non display related) so ill try to uninstall them.
Hawe you got any idea if i can repair it on my own even if i loose the waterproofability?
Or can it be replaced for free if i have a warranty? (I dont have insurance)
Thanks for your tips guys.

If you're under warranty it will likely be a free repair, unless they find other damage. Like moisture damage.
As far as fixing it yourself, it's just about as cheap to have Samsung do it than it is to buy the parts yourself. It's $229 for Samsung to do it, and you'll maintain the water resistance rating.
same has happened to me

This has just happened to my note 8 too. I was about to update it and had started it. set my phone down and picked it up and phone screen is black but can hear the haptic feedback.
I can only see the lock screen and the notifications. Everytime I try to unlock my phone I only get to see a glimpse of the notescreen and then the screen turns black. Even when I try to go to camera through the lock screen the screen goes black too. When I charge my phone it heats up so I haven't really charged it as well. Has this also happened to anyone? It seems as if the phone's sensitivity still works in all places but when I unlock it the screen just goes black.
I also have problem of freezings and always rebooting. Tried soft and hard resets/factory reset. Still same problem. This phone has hardware issue. Do not buy.
I realize this thread is quite old but I have this exact same issue now. I have managed to discover some other information by playing around with various settings which are noted below. To begin with, I was able to used the AOD hack posted above for a while but it no longer works. The only way I can get my screen to come back is with a soft reset - but as soon as the screen times out or i turn it off, it goes black, with or without AOD enable. All the on screen buttons still work as well as the haptic feedback - I just can't see anything.
Now on to what I have found:
One thing I have found is if I turn off adaptive screen brightness and crank the brightness slider to the right, when it goes black I can faintly see some of the buttons - enough that I can turn the phone off or restart it from the power menu (If I switch the default setting to night that also helps to see the buttons a bit better). Also, if I enable night mode I can also see the brightness slider faintly but when I slide it left, it just makes the screen completely black and when I slide it right, it only returns it to the very faint brightness level.
So at this point I am stuck. To summarize the issue:
1. When the screen either times out or turns off, it is still "alive" but goes black. It will not return to normal brightness.
2. Turning off adaptive brightness and cranking brightness slider to right allows you to see faint buttons after screen times out but won't return to normal brightness.
3. Enabling night mode helps to see the faint buttons, in particular the brightness slider a bit better. However the screen still cannot return to normal brightness.
4. The only way to get the screen back to full brightness (albeit temporarily until the next timeout) is to turn off the phone or reset from the power menu; or soft reset holding volume down + power simultaneously.
Hopefully someone else has figured out a way to recover this. I am on Android 9 with Samsung UI 1.0
Phone is completely stock, never rooted and completely out of warranty.

Random screen auto turn on with do not turn on display in notification

My red magic 3 will randomly turn the screen on even with the option to not wake up the screen in every settings I could find. I have seen it happen when I'm driving or walking and even just having the phone on my night stand.
Then screen will turn on and there's no new messages or notifications, it just turns on.
Any ideas as to what I could try?
My friend has this exact same issue! We both have the same phone, mine does not do it but his does. Just, randomly the screen turns on, doens't seem to be related to notifications or anything. If anyone knows what's causing this, it would be appreciated. Thanks!

Screen Black and White.

I bought a screen of eBay which said it was OEM but who knows? Anyway I had the screen installed at a phone repair shop and it seemed to work fine until I walked out of the store and turned it on to notice that the screen was black and white. I turned it on and off again and it went back to normal but i went in to tell them anyway when i was walking in I turned the screen in and off a couple times to see if I could get it to go black and white again and sure enough if did. It seems to turn black and white every couple times I turn it on and off. It doesn't flicker back and forth and it doesn't charge when I'm using the phone also i had a custom ROM installed so I got rid of that to see if it would fix it it didn't and I reset the entire device to no avail but I did notice that to this point I haven't had it go black and white while in the boot-loader and i have tried a lot turning it on and off again and again. I also noticed that there are lines bouncing in the background when the screen is black and white which are also visible when the screen is normal but only barely. Apart from that the screen seems to shake when its in black and white and sometimes the touch wont work for a couple seconds its not a big deal because you can just turn the screen on and off to fix it but its a very strange problem i have contacted the seller and I talked to the man who installed it but I was wondering if it was possible that it was some kind of software issue it seems unlikely but the fact that it doesn't flicker on and off its just either on or off and the fact that i cant seem to get it to happen in the boot-loader is making me wonder I also tried recording my screen and the screen was recorded normally when it was black and white to me.
