ok so i decided to test out a rumor about bathing your smartphone in isopropyl alcohol beings my phone had a bunch of grit/dirt in it. it work just fine before the bath. now it turns on and it functions with 2 problem tho.1) it has dark blotches all over the display.2) it has trouble reading the sim card(as in it still reads the sim card just poorly) and ideas would be great.
Replace the logic board and display assembly. And never put your phone in a liquid, as it will seriously damage it.
