I Just replaced the top glass not the whole digitizer and all. I didn't have anything on the paper towel but I think some oil from my hands. Then I tried to clean it with water so it looked like a really big smudge of oil. When I watch fix it videos all the digitizer looks black and mine looks silver. Also from reading on Google lots of people had this happen to them. It seems maybe the hair dryer made the phone too hot, if extreme heat could damage it. Or just too much pressure. Since I did put some scratches on it maybe I applied too much pressure. Lot of people are saying even the slightest bit too much pressure can damage it. But I still don't get why mine looks silver and not black.
