On Saturday in the morning on November 23, my Samsung Galaxy Tab S7+ screen suddenly flashes out of nowhere when I was watching on YouTube. When I tried to close and open it, it remained unresponsive and flashes before opening again. I tried resting it but then the flashes suddenly go to a specific area (bottom left side in landscape format) and left me an unresponsive tablet. I tried doing diagnostics multiple times and it passed, I removed any APKs and checked if my software is up to date. It seems to have a temporary fix before it starts flashing again.
ANOTHER NOTE: During a flash, the tablet seems to have a faint green line just over the control bar. It reappears suddenly but also goes away when I have tried resetting and forced resetting my tablet. I don't know what to do since I'm just a student using my tablet for school. Right now, I have laid down my tablet for a few hours after forced resetting it. It doesn't seem to have any problems while I'm typing this, but it seems to me it's just a temporary relief.
Hello, Riverious! Since you've already run diagnostics and updated your software, try booting into Safe Mode to rule out third-party apps, or consider doing a factory reset (after backing up your data). If the problem continues, reaching out to Samsung Support or visiting an authorized service center might be the best next step. Hope this helps!
Due to a late response (which is not your fault), my tablet seems to be unresponsive and the screen only flashes near the rear camera. I cannot be sure if it is in safe mode especially it had gone worse. The nearest authorized service center is at Manila, and I'm from Imus, Philippines. It's quite hard to be able to repair this especially that I am a student.
