Hey guys, got my 4 on launch day and I absolutely love it. It's great! I do have a few reception issues but it's not bad, I deal with it and should be better when I get an otter or the ballistic hc( can't decide). Anyway enough bull. I really don't make or receive a lot of calls but when I do I hate to be interrupted. The last few calls I have noticed my 4 switches to speaker out if nowhere!!! Crazy!! I read some of you are having the same problem.(proximity )??? I want my issue resolved. I got it from AT&T and my ?? Is whom should I talk to about replacing or fixing my device??? I did get the apple protection plan if that makes any difference and I'm still in my 30 day mark. Hell my phone still has the factory screen and back plastic on it. Anyway if you guys can steer me in the right direction it would be gladly appreciated. Thanks.
