Why is my screen glitched out?
Hello, recently I've used my s7 to take some underwater shots. The phone has been maybe 20s max under water and ever since then I've been having problems with it's screen. If left for a couple of hours the screen will turn on normally and display everything. But after a few seconds it will start to glitch out. Every single pixel starts changing its colour and the screen becomes rainbow like, then it stays like that until I turn off the screen. If turned on again without the pause the pixels will again glitch out. Anyone have any ideas?
PS: The phone is not under warranty protection so there's that, I can take it to the repair shop, but I'm wondering if I can do anything to fix it without paying.

Is this a good question?
