I walked out of AT&T yesterday 2 phones both covered in ZAGGs front and back and new cases. I noticed phone getting warm, muffled speaker sound and unresposive touch. After reading about the flaws on the back phone I took it out of the case and checked it out. Took off the back Zagg! Love the way it feels and looks. Turned on the sound and 100x better. At this point the white phone started to a striptease. It's not feeling as warm at all anymore but looking pretty hot. I never used my phones bare but I believe these are made just to be naket. Anyway still a bid worried about front screen protector (paid good$ for those) but after seeing the scratch tests WHY not?
