My S7E has been water damaged, the power button doesn't work properly.

Just for reference, the phone is running a custom ROM, Pixel Experience Plus Hero 2 Lte.

So the back glass has some holes in it after i dropped it, and water got into the internal components of the phone when my bottle leaked in my bag.

I have tried to dry off the phone as much as possible by first taking everything i could easily remove off (backglass, thoses black panels on top of the mobo, the mobo itself, and the battery) and using a hair dryer and leaving it open overnight to dry out by itself.

After this, the phone works pretty normally except the power button will open up the power menu on a short press, and the screen times out by itself randomly, even while I am actively using it.

It also feels slower than normal but maybe not.
