I took my EVO geocaching last week. (We used the c:geo app) Throughout the day it changed hands several times but wasn't dropped or anything. One of my friends has long fingernails and we were out in heat (around 100 degrees) I don't know if that affected it at all, but when we got back I noticed sort of a scratched area of the screen with almost bubbles on it. It isn't exactly bubbles as there are none, but the screenguard has a bumpy feel to it now, and it didn't heal in a few days as advertised. Are there fixes for this? Is mine defective?
