HELP!!!!!!!! I am an old lady and having this issue. I did crack my screen and had it replaced at Office Depot. Exactly where is this proximity sensor and how do I remove he screen to scratch paint off? And what does "jailbreak " mean? I am sorry, but I can not afford to take my phone to be fixed but this beeping every time I try to have a call is making me crazy. I swear it makes me so embarrassed I want to cry.
Any advice????
