Safe Mode allows your phone to run as normal but restricts third-party apps or services from being used. If you put your phone in Safe Mode and no longer experience the issue(s), you've determined that the problem is not in your phone's operating system. Instead, it’s likely from an app that’s been downloaded onto your device.
While in Safe Mode, your phone will only have access to core apps that were pre-installed in the phone at the factory.
Once your device has powered on, you should see the words "Safe Mode" in the lower right/left corner of your screen.
If the problem no longer occurs while in Safe Mode, you've determined that the problem is caused by a third-party app that was downloaded to your phone.
