There are three common options for mobile notifications: ring, silent and vibrate or a combination of the three. But there is one more option: the notification light which alerts me to unread texts, incoming or missed calls.
The iPhone doesn’t have a standard notification light, so what options do iPhone users have?
You can actually set your flash to act as a notification light. Here’s how:
Settings > General > Accessibility > LED flash for Alerts and simply slide the button to On.
The LED will flash three times when you receive a standard notification and it will flash non-stop along with an incoming call until the call is answered or ended. Now you don’t need to wake your phone to see if you’ve missed anything!
