Our iPhone SE has been missing calls intermittently over the last month. The 'do not disturb' feature is turned off and the ringer switch is in the on position (the orange bar is not showing.)
We know when we have missed a call because the phone beeps to indicate voice mail, even though the phone has been with us at the time the call was made.
We fix it simply by rebooting the phone but there is no predicting when it will stop working. It usually lasts about a week before the problem reoccurs.
Anyone else have this problem or familiar with the problem? Any long term fixes other than rebooting the phone?
