I exchanged my first 1020 for freezing, rebooting, and Bluetooth issues. When I took off screen protector and case to return I noticed that dust had made its way under the screen glass on the bottom edge and had begun to separate the glass from the phone, showing silver air pockets. One speck made its way about 1/16" up the glass just under back button. Now, a few weeks later with replacement, its beginning again. Anybody else experiencing this? Don't want an otterbox case!!!
