Set iPhone Camera LED to Flash on Incoming Calls and Alerts

The iPhone camera LED flash can be used to alert you to incoming calls, messages, and other alerts to your device. With this feature enabled, anytime a call or messages comes in the devices LED will flash repeatedly, even when the iPhone is on silent mode.

This great feature offers an obvious visual cue with a bright flashing light for when any alert or notification comes in to the iPhone. LED alerts on iPhone are an excellent feature that is not well known, but we’ll show you how to enable this on your iPhone.

How to Enable LED Flash Alert for iPhone with iOS

Using LED flash for alerts is possible in most versions of iOS and with most iPhone devices, here is how you can set this feature for your iPhone:

1. Tap on the “Settings” app and then on “General”
2. Select “Accessibility” in settings
3. Locate “Tap LED Flash for Alerts” and tap on that
4. Now toggle the ON switch next to “LED Flash for Alerts”

Once you get an incoming message, phone call, or alert, the LED flash on the iPhone camera will blink and flash, offering a visual indicator that a notification or alert is coming through to the device.

Undeniably useful for those with hearing difficulties, but flashing the LED alert when an iPhone gets a call or message is also genuinely useful for those of us who regularly keep their phones on mute, lower volume, or who just want the iPhone to be a bit more obvious when an alert comes through.

This setting is supported by all modern iPhone and most versions of iOS, though it has been around for quite some time and the setting may look a little different on newer versus older iPhone models.

For some background, this idea actually started as an old jailbreaking tweak, but Apple adopted it as an accessibility feature for iOS 5 and it persists in all modern versions and added a secondary “flash on silent” option in later versions like iOS 10. The flash LED alerts ability is agreat feature for just about everyone with an iPhone, try it out if it sounds like something you may appreciate.

By the way, desktop users can enable a screen flash on the Mac for alerts which is sort of similar offering a visual clue for alerts and notifications.
