Image Retention (Ghosting): This is a well-known IPS LCD flaw where faint images from previous screens linger. It is often a hardware limitation, but apps like Night Screen or Twilight can mitigate it by applying a slight color filter.
Static Boot Screen: Often caused by custom ROMs and proximity sensor conflicts. This can sometimes be temporarily fixed by covering the proximity sensor for 30 seconds during boot.
Total Black Screen: If the phone vibrates or makes sounds but stays black, the LCD or digitizer has likely failed and requires physical replacement.
Unresponsive Touch: This can be caused by loose internal cables or debris. For water-damaged units, cleaning the logic board connectors with isopropyl alcohol and a stiff brush may restore function. 2. Required Tools and Parts
