If your phone’s flashlight won’t turn on, you may need to take the following steps:
- Check if your flashlight/flashlight app is enabled in your phone’s Settings.
- Check if the flashlight function is set as the default action for the power button (if your phone has one).
- Check if there is a physical button on the side of your phone that corresponds to the flashlight function.
- Check the flashlight app and/or make sure it is up-to-date if you are using a third-party flashlight app.
- Restart your phone completely and check again.
