Why won`t my flight mode turn off??

[Windows Central Question]

My nokia Lumia 520 won`t turn flight mode off! any help

Have you tried restarting your phone? How about performing a soft reset?

This happened to my phone (a different one) and a simple restart resolved the issue.

Restart = power off then power on
Soft Reset = press and hold volume down button and power button until your phone reboots
