Water damage issues after submersion
Yesterday i thought it would be a good idea to take some underwater ab pics with my waterproof phone. After being submerged for about 5 seconds the screen began to get a green hue, and then started flickering. Another few seconds later the whole phone went completely dead. I chucked it in a bowl of rice overnight and the next day it would turn on fine, but face ID wouldn’t work and the screen was still green and flickering. I then used a heat gun on it for a while, and then spent ages shaking it to try to get the water out. This time face id started working, and the green hue was gone but the phone still has a flicker. The haptic feedback is also really loud. Not sure if it has permanent logic board damage or if there’s still some water in there. Any help would be greatly appreciated.
I let it dry for another day, and the next time i powered it on it was functioning as normal excepting the taptic engine. However, about an hour later, the screen suddenly went black with some dim lines flickering across it, and the phone restarted. It was then stuck in a boot loop of showing the apple logo for about ten seconds, then the screen going black and then shutting off. I held all three buttons to shut it off, and then removed the screen and logic board. It’s sitting in isopropyl alcohol for a while, hopefully that will clean it up. The only visible water damage was on the side of the taptics engine and the aluminium cover for the camera module, where you could see some marks from salt water. I couldn’t see anything on the logic board, but i fear the water could have gotten under the processor housing.
