If you forget your Samsung Gravity Smart's password, you can perform a master reset. A master reset clears all data on the device, including call history, contacts, emails, photos, music and apps. You can also use a master reset to fix errors such as periodic crashes or freezes. In addition, you should reset your phone to erase all personal information from the device before you sell it or give it away. Data deleted during the reset cannot be recovered. Data on the SD card should remain intact, but it's generally a good idea to remove the SD card and the SIM card before you reset the Gravity.
