There are a few important things that depend on the flashlight. For example, looking for a thing in a dark room requires a flashlight, making your way through a dark passage needs a flashlight, and importantly LED flashlight (if enabled) also indicates the notifications by blinking twice when iPhone is locked.

Some may think it is not an important feature to be bothered about. It is only when it stops working, they realize that it is quite an important feature. Anyway, don’t be worried too much if your iPhone’ LED flashlight stops working suddenly. It is a common issue reported by many users. It also has been acknowledged by Apple and therefore solutions have been provided already.

Remove Cover

The first step you should take is to remove your iPhone from the protective cover (if any). It is often the case that your cover moves too much and blocks the path of LED Flash or even the rear camera. After removing the case, physically inspect your phone too.

There could be some dust particles that might be playing their part. Clean your iPhone with a soft cloth and check if this method has addressed the issue or not. If it works fine then it is recommended that you change your protective cover/case. If not, move to the next step.

Check Settings

When it comes to settings, the iPhone gets a bit trickier to deal with. Regular updates keep changing the settings section and hence it is no coincidence that users get confused. Your LED flash not working may be entirely down to the settings of your iPhone. You can check your settings to address this issue. Here is how you will be able to do that.

1. Go to the Settings of your iPhone.

2. Tap on the option General.

3. Locate the option Accessibility and tap on it.

4. Scroll down to the section Hearing. Locate the option LED Flash for Alerts.

5. Make sure this option is toggled on. If it is disabled then LED flash won’t work.

Once done, go back to your home screen. Lock your phone as the LED flash will only work when your screen is locked (dark). Now check if LED flash works whenever a notification hits your phone.

Do Not Disturb

Do Not Disturb often brings peace to iPhone users. You will use this feature frequently during the busy hours as you might not want any distraction. However, enabling the DND feature also disable features that many users do not know about. The LED flash is one of the features that gets turned off if DND is enabled. Same goes with the Airplane mode as it delivers the same purpose.

Enabling the DND isn’t an issue if the settings are adjusted appropriately. You can enable DND for a specific time. It will turn off as soon as the set time period ends. In order to do so, you can:

1. Go to the Settings of your iPhone.

2. Locate the option Do Not Disturb.

3. Now toggle on the option Scheduled; it would be the second option on your screen.

4. Now adjust the timings for Schedule. Set them up only for the time when you do not want to receive calls, messages, or LED notifications.

5. Do Not Disturb will automatically get disable as soon as the Schedule ends.

Cool Down

If your phone’ usage is too much then it is likely that it will get heated up and features like Camera and LED Flashlight will stop working. This happens especially when you take too many pictures or record a long video with your flash on.

In that case, your iPhone will show you a warning sign (pop-up) stating Flash is Disabled; The iPhone needs to cool down before you can use the flash. Simply tap ok and then leave your phone to cool down for 20-30 minutes.

Low Power Mode

iPhone asks your permission to enable Low Power Mode whenever your battery goes as low as 20%. Enabling it will save battery by disabling many features. The LED flash isn’t one of them, but yet it stops working when this feature is enabled. It happens rarely, but if it does, then you can disable Low Power Mode to check if flash starts working. Here is how you will be able to do that:

1. Go to the Settings of your iPhone.

2. Tap on the option Battery.

3. Now the second option on this screen would be Low Power Mode. Make sure you toggle it off.

Now go back to your home screen, lock the phone, and check if LED flash works when notification hits your phone.

Reset All Settings

The methods mentioned above usually work for most of the users. However, if you are one unfortunate user that didn’t get any help from these methods then you may have to reset your phone. Here is how you can do it:

1. Go to the Settings of your iPhone.

2. Tap on the option General.

3. Scroll down to the bottom of your screen and tap on the option Reset.

4. Now tap on the option Reset All Settings. Provide your passcode and let iPhone complete the process.

5. Once the phone is ready, check if your phone’ LED flash has started working or not.

This is an evergreen method that usually makes your iPhone as good as new. This method should work for you. You can also restore your iPhone via iTunes as it delivers the same results as Resetting All Settings.
