So after all the hype about the new iPhone I am just fed up with it and am considering returning it and taking my business elsewhere even though I loved my other iPhones this one is just plain disappointing me, the signal issue and yellow spots were bad enough. I am tired of my cheek hanging up on people or putting them on speaker or muting the phone, I now feel I have a proximity sensor problem or maybe it is just plain out to sensitive on this phone I am not sure yet. Is anyone else having these problems with the proximity sensor? What a disappointment this phone has been to me. I am hoping for some solutions if not I am off the iPhone wagon for now.
