Today got strange phone behavior. Phone was near me, lying on the table. Then someone called me. I heard ringtone, but screen is off. I took phone in hands and pressed vol-up to mute call ringtone. Tried to switch on display by power button and display didn't switch on. Vibro is working, i tried (in blind) to push some buttons on screen and it gave some vibro haptics. I tried to push power button twice (it is set to flashlight/torch) - and nothing. Phone didn't turn on flashlight. Then I pressed continously power button and tap to right top corner (reboot) and then phone rebooted.
Had no such behavior on .83 FW and earlier. Have no idea why it happened.
