WARNING! Applying a master reset on your smartphone will return its settings to original factory values. All software updates prior to the reset will be lost, and all personal data stored on the phone's internal memory will be deleted. This includes custom ringtones, apps, images, downloaded content etc. (Remember that data stored on the SD and SIM cards will not be affected)

NOTE: Before factory resetting your smartphone, you should visit this link assuming that you're looking for instructions on how you can back up your personal data stored on the device. For a full guide on restoring the data after the backup, follow this link.
