Deleting All Personal Information from Your Galaxy Tab A (SM-P550, SM-T550, and SM-T350)
Your device lets you perform a factory reset to delete all of your personal information from the device (the microSD™ card is not affected). This feature lets you ensure your data is removed before sending the device in for replacement or repair, properly disposing it, or giving it to a friend or family member.
Perform a Factory Reset
Your personal information cannot be recovered after using this feature. Please save any information you need prior to using this feature.
From the Home screen, touch Apps > Settings > Backup and reset.
Scroll to touch Factory data reset.
Review the information provided. If available, mark the Format SD card checkbox if you also want to delete the information on your microSD™ card, and then touch RESET DEVICE.
Formatting your microSD™ card will remove all personal information from the card. This information cannot be recovered.
If you have a security lock set on the device, you will be prompted to enter the lock information before proceeding. Touch CONTINUE to proceed.

The process may take a few minutes while your device removes your personal data and restores the Android platform to its original state. You can reinstall any downloaded or purchased apps from Google Play store.
Perform a Remote Factory Reset
Google offers an Android Device Manager app that lets you track your Android device's location and reset its memory remotely. Both Location services and the erase feature must be turned on and active on the device.
From your computer, sign into the Android Device Manager webpage using the Google Account associated with the device you want to locate.
Click Accept to allow the location data to be sent to Google.
An interactive dialog box displays in the top-left corner.
Click Erase again to confirm deletion.
