Your iPhone will vibrate, ring when you get a notification (a new text, a new message on your Facebook Messenger, …), nothing fancy, all phones do that BUT it can be cool-er with the LED Flash for Alerts.
The LED in the back of your phone will blink like the lights on your xmas tree on 24th of December.
How to configure your LED Flash ?
- Go to Settings
- Then choose General
- Then click on Accessibility and scroll down to LED Flash for Alerts
