While this feature was intended for those who are hearing impaired, it’s also a great if you want to keep your phone silent but still be visually notified of new emails, text messages, Facebook updates etc.
- Start out by tapping the Settings icon.
- Tap General
- Scroll down to Accessibility and tap it.
- Now scroll down to the LED Flash for Alerts item, and toggle it to ‘on’.
- Now when you receive a new notification the LED light on your iPhone will blink (very brightly!) even if your phone is set to silent/vibrate.
