Apple provides the option to make iPhone Flash its LED light (located next to the Camera), whenever a Call or Text Message is received on your device.
This can help in preventing the possibility of an important call or message being missed, while your device is placed in silent mode and it is also not set to vibrate during silent mode.
Enable LED Flash Alerts on iPhone
Depending on your requirements, you can make iPhone to Flash its LED light only when it is placed in silent mode or make iPhone to both Ring and Flash, whenever a call is received.
The latter option can be useful, if you are visiting or working in a noisy environment, studying or working with music on and also if you prefer keeping the ringer volume on your iPhone to a very low level.
1. Make iPhone Both Flash & Ring When Call is Received
1. Go to Settings > Accessibility > Audio/Visual.
2. On the next screen, scroll all the way down and move the toggle next to LED Flash for Alerts to ON position.
After this setting, you will find the LED light located at the back of your iPhone Flashing multiple times, whenever a Call or Message is received on your device.
Note: Ideally, iPhone should be placed Face Down, so that you can see the LED next to the rear camera flashing.
2. Make iPhone Flash On Calls in Silent Mode
1. Go to Settings > Accessibility > Audio/Visual.
2. Scroll down and move the toggle next to Flash on Silent to ON position.
This will make iPhone Flash its LED light on Calls and Messages, only when it is placed in silent mode.
Here it needs to mentioned that LED Flash Alerts work only when your device is locked, you won’t find iPhone Flashing when it is unlocked or being used.
