The past 2 days my phone has gone into flight mode 3 times. I've tried to change the setting but I keep getting a message saying that the settings can't be reached. I've tried putting my bluetooth on and off, but I still can't change flight mode. I also sat in places where I would normally get full signal to see if it would change but it hasn't. I've had to hard reset my phone each time but I can't keep doing that. Is there any way I can delete the flight mode feature? or prevent flight mode from enabling?
