So if i don’t use my phone for about a day or two then i can use it for a long time atleast 15 mins of usage then the screen starts to corrupt. I suspect it is due to overheating of gpu but last time it got really hot but i got about 12 minutes of usage from the phone. I am planning to go to a repair center but i want to know if there’s another option thank you for your answers or even trying to think about a solution.
Pretty much only thing can be tried is another screen. If that does not work it would simply be too expensive for further diagnosing and board-level repair as the worth of this phone has dropped so much that buying a new one would be the better option.
Have you replaced the screen?
