Phone DIMMING on its own ----
I have only had the iPhone 5 for about 2 weeks and this has happened to me twice already. The screen will start dimming on its own, while I'm using it and even if it's on lock screen, even when I put in my pw and the screen unlocks it's still dim. So then I'd manually lock the screen by clicking the power button on top and then it will be ok again. Though this has happened to be twice already in the past 2 weeks.
Facetime Acting Up ----
I've had people try facetiming me a few times and it continues to tell them that I am unavailable. I would literally take my sister's iPhone, my Mom's iPhone, my Fiance's iPhone to facetime me and all would say that I'm unavailable. I'd go to my settings and would have to turn on/off my facetime for it to work again.
What is going on and should I bring this defected device into Verizon? Please help! Suggestions?
