another person checking in here to assure you that, if you find a stripped screw (or more) at this step, you’re not crazy. I have one as well! I’m in dis-effing-belief. This phone has NEVER been serviced by anyone, and was allegedly brand new when purchased.
To the person suggesting a dremel tool to remedy this…. *blink**Blink*. Are you kidding me right now? *slap*. Vibrating the !&&* out of all those sensitive parts - not to mention what one slip could end in your phone being effectively sawed in half.
