Performing factory reset on smartphones are often the last resort when worst comes to worst. When you do factory reset, all downloaded apps and phone settings will be deleted. Then you'll have a clean phone just like the first time you opened it from its box. Make sure that you back up important files before you perform this. All data saved on your memory card will not be deleted though. Here's how you do a factory reset on Motorola Droid Razr Maxx HD.
1. On your device's screen, tap on Appsand go to Settings menu.
2. Then go to Privacy.
3. Select on Factory Reset and choose Reset Phone.
