IPhone 6 running 9.3.1 no airplane mode
After updating my iPhone 6 to 9.3.1 it will not go into airplane mode.
I can toggle the switch on the settings menu and the switch on the lock screen fine but the phone does not turn off bluetooth, wifi or cellular activity. All 3 stay active. If I force quit the settings app after turning on airplane mode and then re-enter it, it shows as turned off. May also be related but my macbook also said there was an error and the phone couldn't be backed up.
iPhone 6, iOS 9.3.1
