[Question] [Help] waterdamaged iphone 15 pro max
Hey guys, my mom’s iPhone 15 Pro Max got saltwater damage at the beach. I opened it up, cleaned everything with 99.9% isopropyl alcohol, including under the board and all the connectors, which had visible salt residue on them. The phone would still turn on but the screen was completely black, so we ordered a cheap €30 LCD from Amazon just to get her photos off and move the eSIM to her old iPhone 11.
The screen arrived yesterday and everything actually works like WiFi, mobile data, the camera even randomly started working again. The only thing that doesn’t work is Face ID.
The big issue though is that the phone freezes every few minutes, the screen flashes pink, and then it restarts.
Could this be purely a display compatibility issue, or does it sound like board damage? I’m considering buying a proper OLED replacement from iFixit for €180 but I don’t want to spend the money if the board is actually damaged. Any advice would be appreciated!
