My phone keeps showing a line of pixels in random spots on the display before rebooting, it does this randomly with periods of up to like an hour where the phone will work fine, and there’s no outside damage or cracks on the display, Does anyone know what could be wrong?

It sounds like the OLED panel is damaged this usually happens after a drop. As for the reboot issue i suspect that the screen draws too much power causing the phone to semi-randomly reboot.A new display is likely to fix it. but i would take it to a professional who has a warranty on repairs, just in case it’s more than the screen.
