Back screen is completely cooked. Turns on by itself, flashes Apple logo, then turns off (doesn't reach home screen). It used to be black and the Apple logo in the middle but then it turned green with the Apple logo in the middle. Dipped in rice and now I only see a small bit of the screen light up. The back is cracked as hell but the main issue is water damage not the crack itself (was showering and water got into the phone, it's back has been destroyed for months). There's also this tiny black strip coming out of the bottom (2nd picture). I really don't care about getting the back fixed, I care more about replacing the battery but obviously to do that I have to replace the back. Atp i'm considering doing a housing replacement myself or getting an entirely new phone. Would it be better to go to a repair shop, get a new phone, or housing replacement?
