Safe Mode for Android phones is a diagnostic mode that helps you determine the source of the error that is causing your Android device to get stuck, restart, go on a boot loop, run slow, or freeze. If you have just installed a third-party app on your HTC phone and you are experiencing problems, then trying to fix these issues by booting into Safe Mode is recommended before performing a reset or having your device checked by a service center. This tutorial shows how to put your HTC phones in Safe Mode.
