I bought my HTC Evo 4G off of eBay a month ago. It was perfectly fine until I dropped it on my bathroom floor. My phone did not get a scratch and you cannot even tell it was dropped. However when I picked it up it almost looked as if their was a big stain in the middle of my phone a group of dead pixels that practically covers my whole screen! I have ran pixel fixer many times, and I DO NOT want to have to send it back..Is their anything I can do to fix this issue?
