Sometime we are busy in a meeting. The phone rings and you have to press the unlock button and then cut the phone to mute it. In Samsung Galaxy Note 3 this is more easy. There are two ways through which you can mute the phone. The same function also pause a video or audio playback.
Step 1: Enable Control Motions settings from Settings > Controls > Motions.
Step 2: Under Turn Over tap on Mute/Pause.
Step 3: When the phone rings keep it upside down on the table.
Step 4: At the time of ringing phone press the down volume key to mute it.
