I have only been on iOS 9 for two days, but wondering if there are any suggestions or similar experiences in eliminating them. Day 1: Alarm set for 6:00am - Nothing happens. No sound, no vibrate, no screen activity - Go to phone and it is "off". No response from power button, no response from home button. Phone would not respond from holding power button to turn on. Had to hold power + home button to make apple logo appear Day 2: Alarm set for 6:00am - Phone vibrates, but does not respond from home button press or power button press. Screen is black. Had to hold power + home button to make apple logo appear. Any thoughts ? Suggestions ?
