LED Flash for Alerts
If you can’t hear the sounds that announce incoming calls and other alerts, you can have iPhone 
flash its LED (next to the camera lens on the back of the iPhone). This works only when iPhone is 
locked or asleep.
Turn on LED Flash for Alerts. Go to Settings > General > Accessibility > LED Flash for Alerts.
Mono audio and balance
Mono Audio combines the left and right stereo channels into a mono signal played on both 
channels. You can adjust the balance of the mono signal for greater volume on the right or 
left channel.
Turn Mono Audio on or off and adjust the balance. Go to Settings > General > Accessibility > 
Mono Audio.

new voicemail, new mail, sent mail, Tweet, Facebook Post, and reminders. Choose from existing 
patterns, or create new ones. See
