You may want to reset your phone to the original factory settings if you are trying to resolve issues with your phone (for example, you sometimes experience a frozen screen) or if you are giving the phone to someone else.
CAUTION: This should only be done as a last resort. Resetting your phone deletes your ringtones, contacts, pictures, messages, and other downloaded content.
- From the Home screen, press Menu.
- Press # for Settings.
- Select Phone Settings.
- Select Reset Settings.
- Select Master Clear.
- Select Phone.
- Select Yes to confirm.
- The phone is reset to the original factory settings.
