My iPhone screen flickers and corrupts after a period of time of usage

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.

you might want to get a better quality screen. another tip is that always turn the phone off before unplugging the battery. on those 4/4s models, alot of the screen flickering comes from what i assume is a bad grounding of the screen with the frame itself. we dealt with that problem alot in my shop and the fix was to make sure the phone is turned off before unplugging the battery. if at all possible, you always want to disconnect the battery before unplugging ANYTHING else. If you don't you will have all sorts of problems with backlights, cameras, etc.
