What a factory reset does and when you need one

A factory reset erases everything on your Android tablet — all apps, photos, documents, settings, and accounts — and returns it to the state it left the factory. This is useful when your tablet is running slowly, you are selling or giving it away, you forgot your lock screen password, or an app has corrupted your system. The reset itself takes 10 to 30 minutes depending on how much data is stored.

Before you reset, understand that this action cannot be undone. Everything not backed up to the cloud or a computer will be gone. If you use Google Drive, Google Photos, or another cloud service, your files there are safe — they live on Google's servers, not on the tablet itself. But anything stored only on the device will disappear.

Key Takeaways

  • Back up your photos, documents, and any files you want to keep to Google Drive, Google Photos, or your computer before you start the reset.
  • You can reset through Settings > System > Reset options > Erase all data, or by holding Power and Volume Down together during startup if you cannot access Settings.
  • The tablet will ask you to enter your Google account password after the reset completes, so have that password ready.
  • A factory reset takes 10 to 30 minutes and will erase all apps, photos, and personal settings stored on the device itself.

Back up your files before you reset

Open Google Drive on your tablet and upload any documents, spreadsheets, or other files you need to keep. Tap the plus icon, select Upload, and choose the files from your tablet's storage. Google Drive gives you 15 GB free; if you have more than that, you can buy more storage or delete files after the reset.

For photos and videos, open Google Photos and tap your profile icon in the top right. Select Photos settings, then Backup and sync, and turn it on. Google Photos will upload everything to your account. This runs in the background, so you can start the reset while it finishes uploading — your photos will be there when you sign back in.

If you use a computer, you can also plug your tablet into it with a USB cable and copy files directly to a folder on your hard drive. This is faster for large amounts of data and does not depend on your internet connection.

Reset through Settings if you can access your tablet

Open Settings and scroll down to find System or About tablet (the exact name varies by manufacturer). Tap System, then look for Reset options or Factory reset. Tap Erase all data or Factory reset.

The tablet will show a warning that everything will be deleted. Read it, then tap Erase or Confirm. It will ask you to enter your PIN, pattern, or password to confirm you really want to do this — this is a safety step to prevent accidental resets. Enter it and tap Confirm again.

The tablet will restart and show a progress bar. Do not turn it off or unplug it during this time. When it finishes, it will ask you to set up the tablet as if it were new. You will need to enter your Google account email and password so you can read your apps and access your backed-up files.

Reset using hardware buttons if you cannot access Settings

If you forgot your password, your tablet is frozen, or Settings will not open, you can reset using the power and volume buttons. Turn off the tablet completely. Then hold down the Power button and the Volume Down button at the same time for about 10 seconds until you see the Android logo or a menu appear.

Release the buttons. You should see a menu with options like Reboot system now, Wipe data/factory reset, or similar text. Use the Volume Down button to move to Wipe data/factory reset and press the Power button to select it. A second menu will appear asking you to confirm — select Yes and press Power.

The reset will begin. This method is slower than using Settings and may take 20 to 30 minutes. Do not interrupt it. When it finishes, the tablet will restart and ask you to set it up again.

Set up your tablet after the reset

When the tablet restarts, it will ask you to choose a language and connect to Wi-Fi. Do that first. Then it will ask for your Google account email and password. Enter the same Google account you used before — this is important, because it will let you read your apps again and access your backed-up photos and documents.

After you sign in, the tablet will read and reinstall your apps automatically. This can take 15 minutes to an hour depending on how many apps you had and how fast your internet is. You can use the tablet while this happens, but it will be slower.

Your photos from Google Photos and files from Google Drive will appear once you open those apps and sign in. Apps that store data in the cloud — like email, calendar, and note-taking apps — will sync your information once you sign in to them.

What to do if the reset fails or gets stuck

If the reset starts but the progress bar does not move for more than 30 minutes, or if the tablet restarts but still shows your old data, the reset may not have completed. Try again from the beginning, making sure to back up first.

If the tablet will not turn on after a reset, plug it in and let it charge for at least 30 minutes. Some tablets shut down if the battery is too low during a reset. Then try turning it on again.

If you are still stuck after a second attempt, the tablet may have a hardware problem. Contact the manufacturer's support line — you will need the tablet's model number, which is usually on the back or in Settings > About tablet.

Frequently Asked Questions

Will a factory reset remove my Google account?

The reset erases your account from the tablet, but your Google account itself still exists. After the reset, you sign back in with the same email and password, and your apps and backed-up files reappear. Your account is not deleted.

Can I stop a factory reset once it starts?

No. Once you confirm the reset, it will complete. Do not turn off the tablet or unplug it. If you change your mind before you tap Confirm, you can cancel and go back to Settings.

What if I forgot my Google password?

Go to accounts.google.com on a computer and click Forgot password. Follow the steps to reset it using your recovery email or phone number. Once you have a new password, use it to sign in to your tablet after the reset.

Will resetting my tablet make it faster?

Yes, usually. A reset removes old app data, temporary files, and settings that can slow the system down. However, if the tablet is old or has a small amount of storage, the speed improvement may be small.

Do I need to remove my SD card before resetting?

No, but the reset will erase files on the SD card too if you choose the option to erase all data. If you want to keep files on the SD card, remove it before you start the reset.
