Trying to figure out if this is an issue with restoring from backup, or just an iOS 9 issue with the 6S and 6S Plus.
Sometimes when unlocking the phone, the screen freezes, apps take a few seconds to open, etc. It goes away for a while, then comes back (especially if phone has not been used for a few minutes before unlocking again).
