iPhone 5s water damage screen not working
My parter accidentally dropped his iphone5s into the toilet for literally seconds. He said it was working fine so he dried it off and put a towel on the radiator and putting the heating on low : / instead of rice trick etc... He kept phone on and then didn't really think but decided to put it on charge that night as battery was on the verge of dying. He put the phone on to find the screen was completely unresponsive and not working with one vertical line to the left if the screen and little white blocks right at the top of the screen again like I said the screen does not work.
I have switched the phone off and put it in rice for 24hours and switched phone on still got the same problem. I have brought a replacement screen refitted and still the same problem.
Any ideas how to fix this the phone does seem to hold a charge but I have brought another battery just incase
