Have you tried turning it off?
If that doesn't work then try this below and see if that helps.
You perform the soft reset by having your phone turned on. Then press and hold the volume down and Power until your phone vibrates and restarts. Note that you should not touch the device screen during the process (not even when the 'slide down to power off' prompt appears).
How are you getting on with this @shell666? Is your phone still stuck in flight mode?
