Hi everyone, i have a weird problem: my phone's screen works perfectly, i can use it in recovery mode and download. It shows also the boot logo and the battery level while charging (if turned off). But when it loads the os the screen turns black and i don't know what to do. I wiped data by recovery and flashed an official rom with odin but the screen remains black.
The phone is 1 year old, does warranty cover this?

I flashed a custom ROM into my 2din android device and it turned to black screen and nothing appears on it, just a black screen. I tried to go to the recovery mode and I couldn't see anything on the screen , black all the time. I noticed the side buttons of the 2din blinks for a fraction of a second every minute.
Please help me to solve this issue .
Greetings.
I've recently been struggling with a problem with my Galaxy S6 and I've searched far and wide on the interwebs for a solution, with no avail.
You see, whenever I turn my phone on, or wake it up from the lock screen, the screen flickers one or two times, but doesn't always turn on.
They keys are active, touchscreen is active, but no image.
Sometimes I have to try and unlock my screen two or three times to get an image, sometimes it turns on after the first flicker.
An example of what I am experiencing is at https://www.youtube.com/watch?v=CyiDgpUSkaE
[edit] Another example is this: when switching the display brightness, the screen goes to crap and starts flickering like crazy, and at minimum brightness text goes unreadable and small (video) https://www.youtube.com/watch?v=HIMFaCy_KVY
I am not rooted, everything is stock FW, I had android 6 stock and recently upgraded to 7 stock OTA and the same issue persists.
I cannot access download mode or recovery because the screen won't turn on. Only time it turns on is when Android is booted. Even when booting, the blue led flashes because the device is booting but I have no image.
Please contribute with some ideas, I cannot wipe cache from recovery because I can't see anything even if I try to boot recovery (or download).
Thank you in advance!
Did you resolve this issue? If so, how? Mine started to do the same after a short fall. My initial thought was hardware but I can get into recovery and the screen functions just fine there.
So, first I thought my brother's A51 was water damaged because it was wet a little bit and charging was being interrupted. I left the phone turned off for the night and wanted to look at it again the next morning. The problem is that the screen or something else stopped working.
The screen works fine in Download mode, Recovery mode, or at splash screen with phone's model name, the problem begins when it's booting to Android. It's still stuck at the splash screen. no boot animation, no lock screen visible, just a model name. It's not bricked, because I can still unlock the phone (didn't have a password) and I can hear the unlock sound or charging sound (it started working again).
I tried factory reset through recovery - didn't help, flashing fresh firmware from Frija - didn't help. The only thing that changed is now the splash screen brightness goes down a bit and I noticed that until I am touching the screen so the phone can't lock itself it doesn't turn off the splash screen, but when I press the lock button it turns off the screen and I can't turn it back on, but the phone still works because I can hear charging sounds and it shows up in Device manager.
I also opened it because I wanted to see if there's any water damage, but I didn't see any water marks or burnt components. I cleaned the charging board with alcohol and let it dry but that didn't help.
I'm worried that there's something wrong with the motherboard or the charging board because it has a screen connector.
I can also see that some people here have similar issues:

I should also add that I don't have access to settings so I can't unlock OEM and flash custom recovery / ROM. I also cannot downgrade to Android 10 (duh)
I have exactly the same behaviour here.
I ordered a "defect" A51 on Ebay which was not working. I opened it an saw a water damage at the USB-C charging board. Since there was a lot of oxydated parts I ordered a replacement for this board.
After cleaning an replacing the charging board I have the same issue as szerbi. I see the charging screen (while powered off), I can enter download mode and transfering stock firmware using Odin, I can enter recovery mode. While all these states the display works well and I cannot see any damages like a broken display.
I even got it working correctly after several Odin firmware update and recovery mode / factory reset attempts and I could install some apps and set up my google account. I was very happy. But after some hours again: no screen while Android is running.
Now, when Android is running I hear the charging and the screen shot (pressing volume-down + power buttons) sounds and the phone will be visible as a storage device while connecting to a PC.
Conclusion: The display is black while Android is running. Since it was shortly active I assume either a loose contact on one of the flex cable connetions or a water damage at the displays flex board. Unfortunately latter cannot be checked without dividing the display from the display frame. I assume this is an irreversible process.
Hello everyone,
So I bought this one Samsung Galaxy S7 off the flea market for 3€ and when I plugged it in, it showed no signs of life. Then I plugged it in to my powerbank and suddenly, it showed the battery and even the charging animation. I left it charging for a while and then booted it up. It showed the Setup screen as usual, except it had an FRP lock on it. After bypassing that, I got told that I should reset it through settings because the installation is broken or something. After that, all it did was show the Samsung Galaxy S7 screen, then showed the Samsung boot animation screen, after that it showed the "Optimizing apps" and after that the "Installing apps" screen and after that it went black and restarted. From that point on all it did was show the Galaxy S7 screen followed by the Samsung boot animation which sometimes got cut off. After that, I wiped the cache partition hoping that would fix the problem but it did not. After that, I reflashed stock ROM with Odin and it didn't fix the issue either. After that, I flashed TWRP and tried factory resetting it through TWRP because out of nowhere the stock recovery stopped working. It showed the blue screen and then got stuck. In TWRP, after trying to factory reset, it gave me a bunch of errors. (view the image) After that, it got stuck in TWRP and froze. I tried force shutting it off but after that, the notification LED stayed on and the screen stayed black. I left it as it was for a while until the LED shut off. Now, it wont show any signs of life and wont boot in to recovery or download mode. After plugging in the micro USB again, it showed the Samsung Galaxy S7 screen but doesnt go past it. I tried booting it in to download mode but it doesnt want to. Now the screen is completely black and it shows no signs of life at all.
