Factory resetting a device like a tablet essentially puts it back to the state it would be if it was still in the box. It erases your assigned Google account, system and application data and settings and files contained on internal or removable storage such as photos, music and videos.

Performing a factory reset can be useful for a number of reasons and situations. You might want to sell the tablet and make sure all your personal data is removed from the device, for example. It can also be useful if your device has become too clogged up with apps, files and different accounts which may be compromising the performance.

A factory reset is a simple task to carry out but can be tricky to find in the settings menu.

Step One
Navigate to the settings of your tablet either via the icon within the apps menu or by the pop-up Notifications and Setting menu in the bottom right corner of the screen.

Step Four
You will be presented with a warning about the reset and sometimes a tick box to include any present SD card. If you don’t want to erase the data contained on the SD card then make sure you remove it before performing the reset. When you’re ready to take the plunge hit the Reset Device button.
