I think I literally sweat my phone to death...
Long story short, I was working on my GF's grandmas car, and she calls so I was talking to her. I sweat a lot, and the phone screen usually gets covered in sweat. I guess some of it got INTO the phone, and broke my god damn screen. At night, the screen was flickering brightness. I rebooted the phone and it went away, so I figured nothing of it. This morning, I woke up and the screen was flickering bad and then it went black and now it randomly draws purple. the phone works as I can hear it open and run apps. The screen is just black. zero physical damage, water marks on the phone are white. I can see where it was wet on the bottom of the phone inside. Tried taking out the mobo and looking, no signs of corrosion.
help... I don't want to throw a ~$150 LCD screen at it.
