Galaxy s4 missing calls and texts.
I've been having this problem for about two months now, every now and then someone will tell me that they have tried to text me, if I shut the phone off when its back on the the texts will come through, sometimes not till a hour or so later. When someone calls me it wont come through, if I shut the phone off it wont even show up in missed calls when turned back on.
Im not sure what the problem is, when I got my phone it was brand new, there is no damage to it at all. I figured I would ask on here first before trying to call at&t and see if anyone knows what is wrong and if I can fix this.
