What a Factory Reset Does and When to Use It

A factory reset wipes your Android tablet back to the state it left the factory—all your apps, photos, messages, and settings disappear. The operating system stays the same, but everything you added or changed gets deleted. This is useful when your tablet runs slowly, you're selling it, you forgot your lock screen password, or an app keeps crashing and won't stop no matter what you try.

Before you start, understand that this cannot be undone. Back up anything you want to keep: photos, documents, contacts, and any data from apps you care about. If you use Google services, your Google account will restore some things automatically after the reset, but local files and app data stored only on the tablet will be gone.

Key Takeaways

  • A factory reset deletes all your personal files, apps, and settings, returning the tablet to its original state.
  • Back up your photos, documents, and important files to Google Drive, cloud storage, or a computer before you start.
  • You can factory reset through Settings on most tablets, or through recovery mode if the tablet won't turn on normally.
  • The reset takes 5 to 15 minutes, and your tablet will restart several times during the process.
  • After the reset, you'll sign in with your Google account, and some apps and settings will restore automatically.

Factory Reset Through Settings (The Standard Method)

This is the easiest way if your tablet turns on and responds normally. Open Settings, then look for a section called System, About tablet, or Reset options—the exact name varies by manufacturer and Android version. Tap it.

Look for an option labeled Reset, Factory reset, Erase all data, or Reset to factory settings. Tap it. The tablet will ask you to confirm—read the warning carefully, because this step cannot be reversed. Enter your PIN, password, or pattern if prompted. Tap the final confirmation button, usually labeled Erase all data or Reset device.

The tablet will restart and show a progress screen. Do not turn it off or unplug it during this time. The process usually takes 5 to 15 minutes. Your tablet may restart several times. When it finishes, you'll see the setup screen you saw when the tablet was brand new.

Factory Reset Through Recovery Mode (If Your Tablet Won't Start)

If your tablet won't turn on, won't respond to touches, or is stuck on a boot screen, you can reset it through recovery mode. This requires holding down specific buttons while the tablet starts up. The button combination varies by brand: Samsung tablets usually need Power + Volume Up, while others may need Power + Volume Down or a different combination. Check your tablet's manual or search "[your tablet model] recovery mode" to find the exact buttons.

Power off the tablet completely. Hold down the button combination and keep holding it as the tablet powers on. You'll see a menu with options like Reboot system now, Recovery mode, or Wipe data/factory reset. Use the volume buttons to move between options and the power button to select. Choose Wipe data/factory reset or Factory reset. Confirm the choice when prompted. The tablet will erase everything and restart.

This method is slower and more technical than using Settings, so try the Settings method first if your tablet will respond at all.

What Happens After the Reset

When your tablet finishes restarting, you'll see the initial setup screen. Choose your language and region. When prompted, sign in with your Google account—the same one you used on the tablet before, if you had one. This is important: Google will restore your contacts, calendar, Gmail, and some app data automatically.

The tablet will read and reinstall apps that were in your Google Play account. This can take 10 minutes to an hour depending on how many apps you had and your internet speed. You don't have to wait for all of them to finish before you start using the tablet.

Apps that you sideloaded (installed from outside Google Play) will not come back. Files stored only on the tablet—photos you took, documents you created, downloads—will not come back. If you backed these up to Google Drive, OneDrive, or another cloud service before the reset, you can read them again after setup finishes.

Backing Up Before You Reset

The safest backup method is to use Google Drive. Open Settings, tap Google, then Manage your Google Account, then Storage. You get 15 GB free. Tap Back up now to save your contacts, calendar, and app data. For photos and videos, open the Google Photos app, tap your profile picture, then Photos settings, then Backup and sync, and turn it on.

For documents and other files, open Google Drive, tap the + button, then Upload, and select the files you want to save. You can also use OneDrive, Dropbox, or another cloud service the same way. If you have a computer nearby, you can connect your tablet with a USB cable and copy files to your computer's hard drive.

Common Mistakes to Avoid

Do not turn off the tablet or unplug it while the reset is running. If the power dies during a reset, the tablet may not start up again, and you'll need professional help to fix it. If your battery is low, plug in the charger before you start.

Do not assume your Google account will restore everything. It restores contacts, calendar, Gmail, and some app settings, but not photos, videos, or documents stored on the tablet itself. Back these up separately to cloud storage or a computer.

Do not forget your Google account password. After the reset, you'll need to sign in with the Google account that was on the tablet. If you don't remember the password, you can reset it on a computer or phone before you start the tablet reset. If you reset the tablet without signing in with the correct account, you may be locked out.

When to Choose a Partial Reset Instead

If your tablet is slow but you want to keep your apps and files, try clearing the cache first. Open Settings, tap Storage or Apps, then look for Clear cache or Cached data. This removes temporary files that apps create and often speeds things up without erasing anything you care about.

If one app is causing problems, uninstall it instead of resetting the whole tablet. Open Settings, tap Apps, find the problem app, and tap Uninstall. You can reinstall it later from Google Play if you want to try again.

If you just want to erase personal data before selling the tablet but keep the operating system and built-in apps, some tablets have an option called Reset network settings or Erase personal data that is less drastic than a full factory reset. Check your Settings to see if this option exists on your model.

Frequently Asked Questions

Will my Google account restore my photos after a factory reset?

Only if you turned on Google Photos backup before the reset. If you did, open Google Photos after setup and your photos will read. If you didn't back them up, they're gone. Always turn on photo backup before you reset.

What if I forgot the Google account password for my tablet?

Go to google.com/accounts/recovery on a computer or phone and reset your password there. Write down the new password. Then complete the factory reset on your tablet and sign in with the new password during setup.

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 remove the battery. Let it finish, even if it takes longer than expected.

How long does a factory reset take?

The actual reset usually takes 5 to 15 minutes. After that, setup and app reinstallation can take another 10 minutes to an hour depending on your internet speed and how many apps you had.

Will a factory reset remove viruses or malware?

Yes. A factory reset removes everything on the tablet, including any malicious software. However, if the malware came from an app you sideloaded, do not reinstall that app after the reset.
