My phone is in my pocket often as i leave my desk at work; no need to leave my gem out in the open alone... When I set the phone down on hard surfaces, i can hear a bit of a noise almost like two screws tapping together. What I think is, it may be the device that makes the phone vibrate... my real question is if i can feel the phone hitting against my leg as i walk around, is that going to break anything overtime?? or did that create this rogue noise i hear when i set the phone down? Leaning towards paranoia, but wanted to see what i could get!
