I thought apple devices were perfect and never freaked out like this?
I had been using it then put it in my pocket. Was fine. Took the phone out of my pocket and it wouldn't come back to life. Tried plugging it in to a computer and also the wall charger. Still wouldn't work.
Had to hold down menu + power before it would reboot. After it came back up all my own personal apps are trashed on the phone and won't start up. They flash and go away. So looks like a restore from backup.
