What flash notifications do and where to find the setting
Flash notifications are a visual alert that makes your iPhone's camera flash or screen brightness pulse when you get a call, text, or other notification. This feature exists mainly for people who are deaf or hard of hearing, or who work in environments where sound alerts won't work. If you have it turned on and want to turn it off, the setting lives in your Accessibility menu, not in your general notification settings — which is why many people can't find it.
The flash notification feature is separate from your regular notification sounds and vibrations. You can have sound and vibration on, flash notifications on, or any combination of the three. This means turning off flash notifications won't silence your phone or stop it from vibrating.
Key Takeaways
- Flash notifications make your camera flash or screen brightness pulse when you receive alerts, and the setting is in Accessibility, not Notifications.
- You can turn flash notifications on or off for all alerts at once, or control them separately for calls, texts, and other notifications.
- Turning off flash notifications does not affect your sound or vibration settings.
- The exact menu path depends on your iPhone model and iOS version, but the setting is always under Settings > Accessibility > Audio/Visual.
Steps to turn off flash notifications on any iPhone
Open the Settings app on your home screen. Tap Accessibility — it's usually near the bottom of the list. Then tap Audio/Visual.
You will see a toggle labeled LED Flash for Alerts. This is the main flash notification control. Tap the toggle to turn it off. The toggle will turn gray when it's off. That's the fastest way to disable flash notifications completely.
If you want more control, stay in this menu. Below the LED Flash toggle, you'll see options to choose which types of alerts trigger the flash — calls, texts, or both. You can leave the main toggle on but uncheck specific alert types if you only want to disable flash for certain notifications.
Why the setting is hard to find
Flash notifications live in Accessibility because they were designed as an accessibility feature for people who cannot hear audible alerts. Apple groups all accessibility features together, which makes sense from an organization standpoint but means people looking for notification settings in the Notifications menu won't find it.
Many people discover flash notifications by accident — they turn on Accessibility features to test them, or they enable it without realizing what it does, and then see their camera flash when their phone rings. Once you know it's in Accessibility, the setting is straightforward to manage.
What happens after you turn it off
Once you turn off the LED Flash for Alerts toggle, your camera will no longer flash when you receive notifications. Your screen will not pulse or brighten as an alert either. Your phone will still make sounds and vibrate according to your notification settings — turning off flash notifications only removes the visual flash component.
If you change your mind later, you can turn the setting back on the same way: Settings > Accessibility > Audio/Visual > LED Flash for Alerts. The toggle will turn blue when it's on.
Controlling flash notifications for specific alert types
In the Audio/Visual menu, below the main LED Flash toggle, you'll see checkboxes for Phone Calls and Repeated Calls. You can uncheck either of these to stop the flash from triggering on calls while keeping it on for texts, or vice versa. This gives you fine control if you want the flash for some alerts but not others.
If you want the flash to trigger only on repeated calls — when someone calls twice in a row — you can uncheck Phone Calls and leave Repeated Calls checked. This is useful if you want to notice urgent calls but don't want the flash every time your phone rings.
Troubleshooting: the flash still triggers after you turn it off
If your camera is still flashing after you've turned off the LED Flash toggle, first check that the toggle is actually off — it should be gray, not blue. Go back to Settings > Accessibility > Audio/Visual and confirm the toggle is in the off position.
If the toggle is off but the flash still happens, restart your iPhone. Hold down the power button and volume down button together until you see the power-off slider, then slide to power off. Wait 10 seconds, then press the power button again to turn it back on. After the restart, check the Audio/Visual menu again to make sure the setting stuck.
On rare occasions, a buggy app can trigger the camera flash independently of iOS settings. If restarting doesn't work, check which app was active when the flash happened. You may need to uninstall and reinstall that app, or contact the app's support team.
Frequently Asked Questions
Can I turn off flash notifications just for text messages?
The LED Flash for Alerts setting controls all notifications together — you cannot separate texts from calls in the main toggle. However, you can uncheck the Phone Calls option in the Audio/Visual menu to stop the flash for calls only, leaving it on for texts and other alerts.
Will turning off flash notifications affect my emergency alerts?
No. Emergency alerts like Amber Alerts and weather warnings have their own notification system and are not controlled by the LED Flash for Alerts toggle. Those alerts will still come through with sound and vibration according to your settings.
Does flash notifications drain my battery?
Flash notifications use minimal battery power — the camera flash fires for less than a second per alert. Turning it off will not noticeably improve battery life. If you're trying to extend battery, focus on reducing screen brightness or closing background apps instead.
Why would someone want flash notifications on?
Flash notifications are essential for people who are deaf or hard of hearing and cannot rely on sound alerts. They're also useful in loud environments like concerts or factories, or in situations where you need silent alerts, like during meetings or while sleeping.
Is there a way to make the flash brighter or dimmer?
iOS does not offer brightness control for the LED flash alert. The flash uses your camera's standard flash intensity. If the flash is too bright or too dim for your needs, your only option is to turn it on or off entirely.
