How to Reset the Samsung Galaxy Tab to Factory Settings
When the Galaxy Tab acts up and you’ve tried everything possible to fix it without success, you can do the drastic thing and reset all Galaxy Tab software, essentially returning it to the state it was in when it first popped out of the box. Obviously, you need not perform this step lightly. In fact, consider finding support before you start the following process:
Start the Settings app, found in the Apps Menu.
Choose Factory Data Reset.
Touch the Reset Tablet button.
Touch the Erase Everything button to confirm.
All the information you’ve set or stored on the Samsung Galaxy Tab is purged. That includes apps you’ve downloaded, music, synchronized accounts, everything.
Again, do not follow these steps unless you’re certain that they will fix the problem or you’re under orders to do so from someone in Tech Support.
You can also choose to reset the Galaxy Tab’s software and erase everything should you ever return or sell your Samsung Galaxy Tab. Of course, you probably love your Galaxy Tab so much that the mere thought of selling it makes you blanch.
