How do I Delete all my Personal Information from my Samsung Galaxy S III?
Your mobile device enables you to delete all of your personal information from the device (the memory card is not affected). This lets you ensure your data are removed before sending the device in for replacement or repair, properly disposing of the device, or giving the device to a friend or family member to use.
• Your personal information cannot be recovered after using this feature.
• Please save any personal information you need to your computer prior to using this feature.
Deleting All Personal Information
To delete all of your personal information from your device, from the Home screen, touch Apps > Settings > General > Backup and reset > Factory data reset.
