What a Factory Reset Does and When to Use It

A factory reset erases everything on your Samsung tablet — all apps you installed, photos, messages, documents, and settings — and returns it to the state it left the factory. After the reset completes, you will see the setup screen you saw the first time you turned it on. Use a factory reset when you are selling or giving away the tablet, when the device is running so slowly that nothing else has helped, or when you have forgotten your PIN or password and cannot get past the lock screen.

Before you start, understand that this action cannot be undone. If there are photos, files, or other data you want to keep, back them up to a cloud service like Google Drive, Samsung Cloud, or OneDrive before you begin. Also charge your tablet to at least 50 percent battery, because the reset can take 10 to 30 minutes and a dead battery during the process can damage the device.

Key Takeaways

  • A factory reset wipes all your personal data and returns the tablet to its original state, so back up anything you want to keep first.
  • You can reset through Settings on most Samsung tablets, but if you are locked out of your account, you may need to use the hardware button method instead.
  • The reset process takes 10 to 30 minutes and requires the tablet to stay powered on, so charge it to at least 50 percent before starting.
  • After the reset, you will need to sign in with a Samsung account or Google account to set up the tablet again.

Factory Reset Through Settings (Easiest Method)

If you can unlock your tablet and access the home screen, this is the fastest way. Open Settings, then scroll down and tap General Management (on some older models, this may be called About Device or System). Look for an option called Reset or Factory Data Reset.

Tap that option, then read the warning that appears — it will list everything that will be deleted. Tap Reset or Delete All to confirm. The tablet will ask you to enter your PIN, password, or pattern one more time as a safety check. After you do, the reset begins. The screen will show a progress bar or spinning icon. Do not turn off the tablet or remove the battery during this time. When it finishes, you will see the initial setup screen.

Factory Reset Using Hardware Buttons (If Locked Out)

If you cannot unlock your tablet because you forgot your PIN, password, or pattern, you can force a reset using the physical buttons on the device. First, power off the tablet completely. Then press and hold the Volume Up button and the Power button at the same time. Keep holding both buttons until the Samsung logo appears on the screen — this usually takes 5 to 10 seconds.

Release the buttons when you see the logo. The tablet will boot into Recovery Mode, which shows a menu with white text on a black background. Use the Volume Down button to navigate to the option that says Wipe Data / Factory Reset or Factory Data Reset. Press the Power button to select it. A confirmation screen will appear asking if you are sure. Navigate to Yes using Volume Down, then press Power to confirm. The reset will begin and may take several minutes. When it finishes, select Reboot System Now to restart the tablet.

Note: On some Samsung tablet models, the button combination is different. If Volume Up and Power do not work, try holding Volume Down and Power instead, or consult your tablet's manual for the exact combination.

What Happens After the Reset Completes

Once the reset finishes and the tablet restarts, you will see the welcome screen and language selection, just as if the tablet were brand new. You will be asked to connect to a Wi-Fi network, then to sign in with a Google account or Samsung account. If you do not have either, you can create one during setup, or skip this step and create an account later.

After you sign in, the tablet will read and reinstall system updates if any are available. This can take 15 to 30 minutes depending on your internet speed. Once that is done, your tablet is ready to use. You can then reinstall any apps you want from the Google Play Store or Samsung Galaxy Store.

Common Problems and How to Fix Them

If the reset gets stuck on a loading screen for more than 30 minutes, try a hard restart: press and hold the Power button for 10 seconds until the screen goes black, then release and press Power again to turn it back on. If it is still stuck, repeat the hardware button reset method described above.

If you see an error message saying you need to sign in with your Samsung account or Google account before the reset can complete, this is a security feature called Reactivation Lock. You will need to sign in with the account that was originally set up on the tablet. If you do not remember the password, use the "Forgot password?" option on the sign-in screen to recover it through email or phone number.

If the tablet will not turn on after the reset, plug it into a charger and wait 10 minutes — the battery may have drained during the process. If it still will not respond, try the hard restart method above.

Backing Up Your Data Before You Reset

The safest way to back up is to use Google Drive or Samsung Cloud. For Google Drive: open the Settings app, tap Google, then Manage Your Google Account, then the Storage tab. Tap Manage Storage and follow the prompts to back up your photos, contacts, and calendar. For Samsung Cloud: open Settings, tap Accounts and Backup, then Samsung Cloud, and toggle on the types of data you want to back up.

For photos and videos specifically, you can also use Google Photos, OneDrive, Dropbox, or Amazon Photos. Open the app, sign in, and let it upload your media to the cloud. After the reset, sign back in to any of these services and your files will be there to read.

Frequently Asked Questions

Will a factory reset remove the Samsung account from my tablet?

Yes. After the reset, the tablet will ask you to sign in again with a Samsung account or Google account. If you do not remember your password, you can recover it through the sign-in screen using your email or phone number.

Can I stop a factory reset once it has started?

No. Once you confirm the reset, it will run to completion. Do not turn off the tablet or remove the battery. If something goes wrong, wait for it to finish, then try again or contact Samsung support.

How long does a factory reset take?

Most resets take 10 to 30 minutes, depending on how much data is on the tablet and how fast your device is. The hardware button method may take slightly longer than the Settings method.

Do I need Wi-Fi to factory reset my tablet?

No. The reset itself does not require an internet connection. However, after the reset completes, you will need Wi-Fi to sign in with your Google or Samsung account and to read system updates.

What if I forgot my Google password and cannot sign in after the reset?

Go to the Google sign-in screen and tap Forgot password? You can recover your account using a recovery email address or phone number linked to your account. If you do not have access to either, visit the Google Account Recovery page on a computer to verify your identity and regain access.
