Add a Few Seconds of Silence to Your Ringtone so You Don’t Get Confused
When your phone starts ringing at the wrong time, trying to turn it off is difficult. Build a buffer by adding a few seconds of silence to the beginning of your ringtones so you only feel the vibrations first.
Many phones can be set to both vibrate and sound when a call is received. However, if you are in a meeting or in a movie, the sound can interfere with those around you. By adding a few seconds of silence to the beginning of your ringtone, you will feel like your phone is buzzing before the ringtone actually starts making noise. Those few seconds will (hopefully) be enough time to silence your phone before the glitch gets worse.
Create your own ringtone with five seconds of silence at the beginning. | Reddit
