I'm loving my new iPhone 5c (blue with16gb) but I notice that when I call sometimes the phone shows the apple symbol like its about to turn off. It shows it only when I have it up to my ear making a call to another person. Then the apple screen goes away and it asks my to type my passcode in and it hangs up the call. Any ideas about that??? Also I have very good hearing but I can hardly hear the 5c when I'm on the phone with someone because it's so quiet even with the volume all the way up. I do however love the actual speakers on the bottom they sound amazing on games and garage band and they can get pretty loud.
