Turn your iPhone camera into a blinking alert light iOS tip: Turn the iPhones camera flash into a blinking alert lightWant to see rather than just hear that your iPhone is ringing? You can, with a little help from the iPhone’s camera flash.

In just a few taps, you can set the LED flash for the iPhone’s rear-facing camera to blink anytime a call comes in, whenever a text pops into your message inbox, or for any other iPhone event that would normally set off an alert tone or vibration.

iPhone LED flash alert setting 300x223 iOS tip: Turn the iPhones camera flash into a blinking alert light

Just flick the “On” switch to turn the iPhone camera flash into an alert light for incoming calls, texts, and more.

It’s a handy feature for iPhone users (particularly hard-of-hearing ones) who can’t rely on audio alerts to screen notifications; keep in mind, though, that you will (of course) have to lay your iPhone face-down to see the camera flash blinking.

Also, you can’t set the camera LED to flash for specific alerts. Instead, it’s an all-or-nothing deal.

Here’s how to do it:

  • Go to the iPhone home screen, then tap Settings, General, Accessibility.
  • Scroll down until you see the “LED Flash for Alerts” setting, then flick the switch to “On.”
  • Test it by asking a friend to call your iPhone—and when they do, the flash on the rear iPhone camera will start blinking in time to the ringer.
