The iPhone has a great feature which can automatically detect if the phone is up against your ear during a call. It is called the “Proximity Sensor”. It works well, however you may find yourself mysteriously muting a phone call. Your ear can sometimes play tricks on you! Here is a great tip if you have a habit of not putting the phone all the way on your ear during a call.
1. Dial your call normally.
2. Once phone call is made, click the “keypad” and resume your conversation. No more “muting” calls from the ear!
