What a factory reset does and when you need one

A factory reset erases everything on your Android tablet — all apps, photos, files, accounts, and settings — and returns it to the state it was in when it left the factory. This is different from a straightforward restart, which just turns the device off and back on without deleting anything.

You might need a factory reset if your tablet is running slowly, freezing constantly, or behaving erratically after installing an app. A reset also solves problems where you've forgotten your PIN or pattern lock, or when you're preparing to sell or give away the device. If your tablet is stuck in a boot loop (turning on and off repeatedly without loading), a factory reset may be the only way to fix it.

Before you reset, understand that you cannot undo it. Back up anything you want to keep — photos, documents, contacts — to cloud storage like Google Drive, OneDrive, or your manufacturer's cloud service. Once you start the reset, those files are gone.

Key Takeaways

  • A factory reset deletes everything on your tablet and returns it to its original state, so back up your files first.
  • The most common reset path is Settings > System > Reset options > Erase all data, though the exact menu names vary by manufacturer and Android version.
  • If you're locked out of your tablet, you may be able to reset it from the boot menu (the screen that appears before Android loads) without entering your PIN.
  • After a reset, your tablet will ask you to sign in with a Google account; use the same account you used before to restore some apps and settings automatically.
  • If your tablet won't turn on or is stuck in a boot loop, a factory reset from the boot menu is often the only option, but it requires patience and precise button timing.

Reset through Settings if your tablet turns on normally

If your tablet starts up and you can navigate the menus, this is the simplest reset method. Open the Settings app (usually a gear icon) and look for a section called System, About, or Advanced. The exact name depends on your tablet's manufacturer — Samsung calls it Device care, while Google Pixel tablets use System.

Once you find the right section, look for Reset options, Factory reset, or Erase all data. Tap it, and the tablet will show you a warning that all data will be deleted. Read this carefully to make sure you understand what's about to happen. The tablet will ask you to confirm by typing a word like "delete" or by entering your PIN one more time. After you confirm, the reset begins — this usually takes 5 to 15 minutes, and your tablet will restart several times on its own.

Do not turn off your tablet or remove the battery during a reset. Let it finish completely, even if it seems to be taking a long time. When it's done, you'll see the initial setup screen asking you to choose a language and sign in with a Google account.

Reset from the boot menu if you're locked out

If you've forgotten your PIN, pattern, or password and can't get into Settings, you can still reset the tablet using the boot menu — the screen that appears before Android loads. This method works on most Android tablets, though the button combination varies by manufacturer.

Power off your tablet completely. Then hold down the Power button and the Volume Down button at the same time for about 10 to 15 seconds. You should see a menu with options like "Recovery mode" or "Reboot bootloader." Use the Volume buttons to highlight Recovery mode and press Power to select it. The tablet will load into a different menu with white text on a black background.

From this recovery menu, use the Volume buttons to navigate to an option that says "Wipe data/factory reset" or "Format data." Press Power to select it. The tablet will ask you to confirm — usually by highlighting "Yes" with the Volume buttons and pressing Power. The reset will take several minutes. When it's done, select "Reboot system now" to restart your tablet.

The exact button combination and menu names vary: Samsung tablets often use Power + Volume Up, while others use Power + Volume Down. If the first combination doesn't work, try the other. If neither works, search for your specific tablet model and "recovery mode" to find the right buttons.

What to do if your tablet is stuck in a boot loop

A boot loop means your tablet keeps turning on and off without ever fully loading Android. This usually happens after a failed software update or a corrupted system file. The only fix is a factory reset from the boot menu, since you can't access Settings.

Follow the boot menu reset steps above, but be prepared for the process to take longer than usual — sometimes 20 to 30 minutes. The tablet may appear to be frozen or unresponsive, but resist the urge to force it off. Let it sit and complete the reset without interruption. If it's still looping after a full reset, the problem may be a hardware issue, and you should contact the tablet's manufacturer or a repair shop.

Signing back in and restoring your data

After the reset completes, your tablet will walk you through the initial setup. You'll choose a language, connect to Wi-Fi, and then sign in with a Google account. Use the same Google account you used before the reset — this allows Google to restore some of your apps, contacts, and settings automatically.

The restoration process happens in the background over the next few hours, especially if you have many apps. You'll see a notification that says "Restoring your apps and data" or similar. Don't be alarmed if some apps don't return — apps you sideloaded (installed from outside the Google Play Store) won't restore automatically and must be reinstalled manually.

Files you backed up to Google Drive, OneDrive, or another cloud service can be downloaded again once you install the relevant app. Photos and videos backed up to Google Photos will reappear in the Photos app once you sign in. Contacts synced to your Google account will also return automatically.

Troubleshooting a reset that won't start or complete

If you tap the reset button in Settings and nothing happens, restart your tablet first — sometimes the Settings app becomes unresponsive. Hold the Power button until you see a shutdown menu, tap Power off, wait 30 seconds, then turn it back on.

If the reset starts but gets stuck on a loading screen, wait at least 30 minutes before assuming it's frozen. Factory resets on tablets with large storage can take longer than expected. If it's still stuck after an hour, force a shutdown by holding the Power button for 10 to 15 seconds, then try the boot menu reset method instead.

If the boot menu won't appear, your tablet's buttons may be damaged, or the device may have a hardware problem. At this point, contact the tablet's manufacturer (Samsung, Apple, Lenovo, etc.) or take it to an authorized repair center. Do not attempt to open the device yourself.

Preparing your tablet before selling or giving it away

If you're passing your tablet to someone else, a factory reset is essential — it removes your accounts, files, and personal data. After the reset completes and the tablet shows the initial setup screen, do not sign in with your own Google account. Let the new owner complete the setup with their own account instead.

If you're selling the tablet online, take a photo of the setup screen to prove the reset was successful. This reassures the buyer that the device is clean and ready for their use. Some buyers may ask you to leave it at the setup screen rather than completing the setup yourself.

Frequently Asked Questions

Will a factory reset remove my Google account?

Yes, a factory reset removes all accounts from your tablet, including Google, email, and social media accounts. When you set up the tablet again, you'll need to sign in with a Google account — ideally the same one you used before, so your apps and settings restore automatically.

Can I stop a factory reset once it starts?

No. Once you confirm a factory reset, it cannot be stopped or undone. This is why backing up your files beforehand is so important. If you change your mind before confirming, tap Cancel or the back button.

How long does a factory reset take?

Most factory resets take 5 to 15 minutes if done through Settings. Boot menu resets can take 20 to 30 minutes, especially if your tablet is stuck in a boot loop. Do not interrupt the process — let it complete fully even if it seems slow.

What if I don't remember my Google account password after the reset?

Visit the Google Account Recovery page on a computer or another device and follow the steps to reset your password. You'll need access to a recovery email or phone number you set up with the account. Once you've reset your password, use it to sign in on your tablet.

Will resetting my tablet fix a cracked screen or broken button?

No. A factory reset only fixes software problems — slowness, freezing, or corrupted files. Physical damage like a cracked screen or broken buttons requires hardware repair and cannot be fixed by resetting. Contact the manufacturer or a repair shop for hardware issues.
