Over the weekend, after I just upgraded to the new iOS7, my phone shut off more then (5) times. If I was texting or at the unlock screen or getting map direction in the car the iPhone would just shut off completely. Even if I held down the power button for (5) minutes it wouldn't turn back on. Very frustrating specially when I use my phone for everything. Is there something I'm doing wrong because I'm about to turn in this phone.
I just had a refurbished phone sent to me because my iPhone5 was having another data leak. Now the replacement is operating on iOS7 and it has shut off randomly for 5 to 10 minutes three times in three days. I'm going to contact technical support again and ask for another replacement.
