Hello, my iPhone 5 running iOS 7.0.3 has been acting very weird lately and I'm looking for some advice on how to solve my issue. It has been turning itself off every now and then for a week and a half now. Yesterday the time between the restarts just became less and less for every restart and now it doesn't even finish the startup process. When I connect my charger it's stuck in a loop of trying to startup for 3 seconds then shutting off and trying again. Why is the phone restarting all the time? I tried doing a reset a week ago but it's not any different. I can't get the phone to start so I can't do anything in itunes or on the phone. Is it hardware or software related? If hardware related what part is messed up?
