What the notification flash does and how to disable it

The notification flash is the bright LED light on the back of your iPhone that blinks when you get a call, text, or alert. It's meant to get your attention when your phone is face-down or silent. If you find it distracting or don't need it, you can turn it off in Settings in about 30 seconds.

The flash works independently from your ringtone and vibration settings, so turning it off won't affect how your phone alerts you in other ways. You'll still hear sounds and feel vibrations if those are turned on.

Key Takeaways

  • The notification flash is controlled in Settings under Accessibility, not in the main notification panel.
  • You can turn off the flash for all notifications at once, or keep it on for calls only.
  • Disabling the flash does not affect your ringtone, vibration, or any other alert method.
  • The setting works the same way on all recent iPhone models.

Steps to turn off the notification flash

Step 1: Open Settings. Tap the gray gear icon on your home screen or in your app library.

Step 2: Go to Accessibility. Scroll down and tap "Accessibility." It's usually about halfway down the Settings menu.

Step 3: Tap Audio/Visual. Under the Accessibility menu, look for "Audio/Visual" and tap it. This section controls how your phone uses lights and sounds to alert you.

Step 4: Find LED Flash for Alerts. Scroll down until you see "LED Flash for Alerts." The toggle next to it will be green (on) if the flash is currently enabled.

Step 5: Turn off the toggle. Tap the toggle so it turns gray. The flash will now stop blinking when you receive notifications.

That's it. Your phone will no longer flash its LED light for incoming alerts. If you change your mind later, you can turn it back on by following the same steps and tapping the toggle again.

What happens when you turn off the flash

Once the flash is disabled, your iPhone will stop using the LED light to alert you to notifications. You'll still receive all your alerts — your phone will just use other methods to notify you instead.

If you have sound turned on, you'll still hear your ringtone or notification sound. If you have vibration enabled, your phone will still vibrate. The flash simply removes one layer of notification; it doesn't silence your phone or hide your alerts.

Some people turn off the flash because they find it jarring in dark rooms, or because they don't need the extra alert when they're already looking at their phone. Others keep it on because they want every possible way to notice an incoming call or message.

Keeping the flash on for calls only

If you want the flash to blink for phone calls but not for text messages or other notifications, you'll need to adjust your notification settings for each app individually. The LED Flash for Alerts toggle is all-or-nothing — it either flashes for everything or nothing.

To control which apps can send you notifications at all, go back to Settings, tap "Notifications," and then tap each app. From there you can turn off notifications for specific apps, which will prevent them from triggering the flash.

This approach takes longer than a single toggle, but it gives you more control over what gets your attention and what doesn't.

The flash doesn't work on all iPhone models

Older iPhones, particularly models before the iPhone 11, had a dedicated LED flash for notifications. Newer models use the camera flash or screen flash instead, which is why the setting is in Accessibility rather than in a dedicated camera section.

If you have an iPhone 12 or newer, the "LED Flash for Alerts" setting may use your screen to flash instead of a traditional LED. The effect is similar — a bright flash to grab your attention — but it uses different hardware.

If you don't see the "LED Flash for Alerts" option in your Accessibility menu, your iPhone model may not support this feature, or it may be labeled differently on your device.

Troubleshooting: The flash is still on after you turned it off

If you've turned off the toggle but the flash still blinks, restart your iPhone. Sometimes the setting doesn't take effect until you power the phone off and back on. Hold the power button until "Slide to Power Off" appears, swipe to turn off the phone, wait 10 seconds, then press the power button again to turn it back on.

If the flash still appears after a restart, check that you're in the right menu. The setting is in Settings > Accessibility > Audio/Visual, not in the main Notifications panel. Many people look in the wrong place first.

If the flash continues even after you've confirmed the toggle is off and restarted, your phone may have a hardware issue with the flash itself. In that case, contact Apple Support or visit an Apple Store to have it checked.

Frequently Asked Questions

Will turning off the flash stop me from seeing my notifications?

No. The flash is just one way your phone alerts you. You'll still get sounds, vibrations, and notifications on your lock screen and in your notification center. Turning off the flash only removes the blinking light.

Can I turn off the flash for some apps but keep it for others?

Not directly. The LED Flash for Alerts setting is global — it's either on for everything or off for everything. If you want to stop notifications from specific apps, you can turn off notifications for those apps in Settings > Notifications.

Does the flash use a lot of battery?

The LED flash uses very little battery power. Turning it off won't noticeably extend your battery life. Most people turn it off for comfort or preference, not to save power.

Why is the flash setting in Accessibility and not in Notifications?

Apple groups the flash setting with other accessibility features because it's designed to help people who may not hear sounds or feel vibrations. It's an alternative way to receive alerts, which is why it lives in the Accessibility menu.

Can I make the flash brighter or dimmer?

No. The flash brightness is fixed and can't be adjusted. Your only options are to turn it on or off.
