I got a galaxy s off craigslist used (dumb idea i know). worked great for the past 2 weeks. then today (this is ironic) i was changing out the power supply on my computer and was playing with my phone in between futzing around with internal computer parts. finished up, went to grab my phone and the screen started to f up. now i can only see literally the top of it. And I dont mean a half. Literally just the top where it shows the time, icons, and a tiny bit of the wallpaper. the rest of my screen (3/4 of it) is black. there is also a blue pixel dot to the right so yes my phone is still ON and working, I can see the top half.
