Imagine this: you have to switch your iPhone to the silent mode, and there can’t be any vibration alert either. How do you, then, know if there’s a call coming in or if someone messaged you?
Kind of tough without the vibration mode, right? Well, actually, it ain’t.
Accessibility features in the iPhone make it an easy thing with the LED flash alert. The LED flashlight on the iPhone is quite powerful (and sometimes enormously so, if you’re staring right at it). By configuring this accessibility setting, you can actually let your iPhone go into stealth mode – no volume, no vibration – but still, know if there’s a call or a message.
This feature can be helpful – very much – in situations where you can’t let the iPhone be in the vibrate mode too. Just put your iPhone face-down, and when there’s call coming in (or text), the LED flashlight will indicate it with three quick, sharp flashes.
How to enable LED flashlight alerts for texts and calls on iPhone
Step #1. Tap on Settings → Tap on General.
Step #2. Scroll down the line to find “Accessibility” and tap it.
Step #3. Tap on “LED Flash for Alerts.”
Step #4. Toggle the switch next to “LED Flash for Alerts.”
Now, every time you get a message or a call, you’ll be notified of it with a sharp burst of lighting from the flashlight.
An interesting thing to notice, however, is that you’ll have to keep your iPhone face-down so you can see the flashlight. By default, the home screen lights up every time there’s a notification or a call alert but then, that’s easily missed.
I found this feature quite useful because often, I can’t let the iPhone be on vibrate mode either (besides silencing the sounds) because the vibration motor is just too powerful.
