What a Master Reset Does and When You Need One

A master reset, also called a factory reset, erases everything on your Samsung tablet and returns it to the state it was in when it left the factory. This means all your apps, photos, videos, documents, contacts, and settings disappear. The operating system itself stays the same — a tablet running Android 12 will still run Android 12 after the reset, but without any of your personal data or customizations.

You might need a master reset if your tablet is running slowly, freezing constantly, or behaving erratically. A reset can also help if you are selling or giving away the tablet and want to make sure the next owner cannot access your information. If you forgot your PIN or password and cannot get past the lock screen, a master reset is sometimes the only way forward.

Before you start, understand that this process cannot be undone. Once you confirm the reset, your data is gone. Back up anything you want to keep — photos, documents, contacts, app data — to cloud storage like Google Drive, Samsung Cloud, or OneDrive before you proceed.

Key Takeaways

  • A master reset wipes all personal data from your tablet and returns it to factory settings, and the process cannot be reversed.
  • You can reset through Settings on most Samsung tablets, but you will need your Google account password if you set up a Google account on the device.
  • If you cannot access Settings because you are locked out, you can force a reset using hardware buttons, though the exact button combination varies by model.
  • After the reset completes, your tablet will restart and ask you to set it up again, just as if it were brand new.
  • Back up your photos, documents, and other files to cloud storage before starting, because all data on the tablet will be permanently deleted.

Reset Through Settings When You Can Access Your Tablet

If your tablet turns on and you can navigate to the Settings app, this is the straightforward route. Open Settings, then scroll down and tap General Management (on some older Samsung tablets, this section may be called System or About Device). Look for an option labeled Reset or Reset Options.

Tap Factory Data Reset or Reset Device. The exact wording depends on your tablet model and Android version. Samsung will show you a summary of what will be deleted and ask you to confirm. Read this carefully — it is your last warning before the data disappears. Tap the button to confirm, usually labeled Reset or Delete All.

Your tablet will restart and begin the reset process. This can take several minutes. Do not turn off the tablet or remove the battery during this time. When it finishes, the tablet will restart again and show you the initial setup screen, as if it were brand new out of the box.

What Happens If You Are Locked Out of Settings

If you cannot unlock your tablet because you forgot the PIN, pattern, or password, you cannot reach Settings to perform a reset through the normal route. In this case, you will need to use a hardware reset, which forces the tablet to reset without needing to unlock it first.

The button combination for a hardware reset varies by Samsung tablet model. For most recent Samsung tablets, hold the Volume Up button and the Power button together until the Samsung logo appears, then release both buttons. Some older models use Volume Down and Power instead. A few models require you to hold all three buttons: Volume Up, Volume Down, and Power.

When you hold the buttons, your tablet will vibrate and show the Samsung logo. Keep holding until a menu appears with options like Reboot System Now, Wipe Data/Factory Reset, and others. Use the volume buttons to navigate to Wipe Data/Factory Reset and press the Power button to select it. Confirm the reset when prompted. The tablet will then reset and restart.

Handling Google Account Lock After Reset

After a master reset, Samsung tablets running Android 5.1 and newer have a security feature called Factory Reset Protection (FRP). This means that after the reset completes and your tablet restarts, it will ask you to sign in with a Google account. If you do not remember which Google account was on the tablet before the reset, you will not be able to proceed past this screen.

If you are the original owner and remember your Google account email and password, sign in with those credentials. Your tablet will then finish setting up and you will have access to it. If you cannot remember the account details, you have a few options: try common email addresses you may have used, check your email recovery options if you have access to a recovery email or phone number, or contact Google's account recovery service to regain access to the account.

If you are setting up a tablet you received from someone else and do not have access to their Google account, you will need to contact the previous owner and ask them to remove the device from their Google account before you can use it. Some carriers and retailers can also help with this if you have proof of purchase.

Preparing Your Tablet Before You Reset

Before you start a master reset, take time to back up the data you want to keep. Open the Settings app and look for Accounts or Cloud and Accounts. Check which accounts are synced — typically your Google account, Samsung account, and any other services you use. Google automatically backs up contacts, calendar events, and some app data if you are signed in.

For photos and videos, open Google Photos or Samsung Gallery and turn on backup if it is not already on. This uploads your media to cloud storage so you can read it later on another device. For documents and files, use Google Drive, OneDrive, or Dropbox to upload anything important. Make a note of any apps you have paid for or customized heavily, because you will need to reinstall them after the reset.

If you have a Samsung account, sign in to Settings and check Samsung Cloud to see what is being backed up there. Samsung Cloud can store photos, videos, contacts, and some app data. Once you have confirmed that your important data is backed up somewhere, you are ready to proceed with the reset.

What to Do After the Reset Is Complete

When your tablet restarts after the reset, it will walk you through the initial setup process. You will be asked to choose a language, connect to Wi-Fi, and sign in with a Google account. Use the same Google account that was on the tablet before if you want to restore your backed-up data — contacts, calendar events, and some app data will sync automatically.

After setup finishes, open the Google Play Store and go to My Apps and Games to see your installed apps. Any apps you had before the reset will appear in the Library section. You can reinstall them by tapping the read icon next to each one. This process can take a while if you had many apps, so be patient.

Restore your photos and videos by opening Google Photos or Samsung Gallery and signing in with the account you used for backup. Your media should appear and begin syncing to the tablet. For documents and files, open Google Drive, OneDrive, or whichever service you used and read the files you need.

Troubleshooting a Reset That Will Not Complete

Occasionally a reset gets stuck or fails to finish. If your tablet is frozen on the reset screen or the progress bar has not moved in several minutes, try a force restart. Hold the Power button for 10 to 15 seconds until the tablet vibrates and restarts. This will interrupt the reset, but it may allow you to try again.

If the reset keeps failing, the tablet may have a software problem that a straightforward reset cannot fix. Try connecting the tablet to a computer and using Samsung's Smart Switch software to perform a reset from the computer instead. You can read Smart Switch from Samsung's website for Windows or Mac. This sometimes works when the tablet's own reset function fails.

If the tablet still will not reset or will not turn on after a reset attempt, the hardware may be damaged or the storage may be failing. At this point, contact Samsung support or visit a service center. Do not attempt further resets, as they may cause more damage.

Frequently Asked Questions

Will a master reset remove the Android operating system from my tablet?

No. A master reset only removes your personal data and settings. The Android operating system stays on the tablet. Your tablet will still run the same version of Android it had before the reset.

Can I stop a master reset once it has started?

Once you confirm the reset in Settings, the process begins and cannot be stopped. Do not turn off the tablet or remove the battery while the reset is running, as this can cause serious problems. Let it finish, even if it takes several minutes.

What if I reset my tablet but forgot to back up my photos?

Once a master reset completes, your photos are permanently deleted from the tablet. However, if you had Google Photos or Samsung Gallery set to back up automatically before the reset, your photos may still be in cloud storage. Sign in to Google Photos or Samsung Cloud on another device to check.

Do I need a password to do a master reset?

If you can access Settings, you do not need a password — just your confirmation. If you are locked out and using a hardware reset, you do not need a password either. However, after the reset completes, you will need your Google account password to sign back in and finish setup.

How long does a master reset take?

A master reset usually takes 5 to 15 minutes from start to finish, depending on how much data is on the tablet and how fast the storage is. Larger tablets with more data may take longer. Do not interrupt the process.
