What a factory reset does and when you need one

A factory reset erases everything on your Samsung tablet — all apps, photos, messages, contacts, and settings — and returns it to the state it left the factory. The tablet itself keeps working; you are just clearing the storage and starting fresh. This is useful when you are selling or giving away the device, when it is running slowly and you want a clean start, or when you have forgotten your lock screen password.

A factory reset is permanent. Once you start the process, you cannot undo it. Before you begin, back up anything you want to keep — photos, documents, contacts — to a cloud service like Google Drive or Samsung Cloud, or to a computer.

The steps differ slightly depending on whether you can unlock the tablet or not. If you remember your password or pattern, the process takes about five minutes. If you are locked out, it takes longer and requires a Samsung or Google account.

Key Takeaways

  • A factory reset erases all data on your tablet and returns it to factory settings, and the action cannot be undone.
  • If you can unlock your tablet, go to Settings > General Management > Reset > Factory Data Reset and confirm.
  • If you are locked out, you will need to enter your Samsung account or Google account credentials to complete the reset.
  • Back up your photos, documents, and other files to Google Drive or Samsung Cloud before you start.
  • After the reset completes, the tablet will restart and ask you to set up as if it were new.

Factory reset when you can unlock the tablet

Open Settings on your home screen or by swiping down from the top and tapping the gear icon. Scroll down and tap General Management. Tap Reset, then tap Factory Data Reset.

The tablet will show you a summary of what will be deleted. Read it, then tap Reset at the bottom. You may be asked to enter your lock screen password or pattern to confirm — this is a safety step to prevent accidental erasure. Enter it and tap Reset again.

The tablet will restart and begin erasing data. This can take five to fifteen minutes depending on how much is stored. Do not turn off the tablet or remove the battery during this time. When it finishes, the tablet will restart and show the initial setup screen, as if it were brand new.

Factory reset when you are locked out

If you cannot unlock your tablet because you forgot the password or pattern, you can still reset it, but the process is longer. Turn off the tablet completely. Press and hold the Volume Up button and the Power button at the same time until the Samsung logo appears, then release both buttons.

You will see a menu with options in white text. Use the Volume Down button to navigate to Wipe data/factory reset and press the Power button to select it. A confirmation screen will appear. Navigate to Yes using Volume Down and press Power to confirm.

The tablet will erase and restart. When it finishes, it will ask you to sign in with a Samsung account or Google account. You must have the credentials for whichever account was set up on the tablet originally — the tablet will not let you proceed without it. If you do not remember the account details, you will need to recover that account through Samsung or Google's account recovery process before you can use the tablet again.

What happens after the reset is complete

Your tablet will restart and show the setup screen you saw when it was new. You will be asked to choose a language, connect to Wi-Fi, and sign in to a Google account or Samsung account. You do not have to use the same account as before — you can set up a new one if you wish.

After you sign in, the tablet will read and reinstall any apps that were associated with that account. This can take several minutes depending on how many apps you had and your internet speed. Your photos and files will not return unless you restore them from a backup you made before the reset.

If you are giving the tablet to someone else, stop after the setup screen and hand it to them. They can then sign in with their own account and set it up as their own device.

Backing up before you reset

The easiest way to back up is through Google Drive. Open Settings, tap Accounts, then Google, select your Google account, and tap Account sync. Make sure Photos, Contacts, and Calendar are toggled on. These will sync automatically to your Google account and will be there when you sign back in after the reset.

For photos and videos, you can also use Samsung Cloud. Open Settings, tap Accounts, then Samsung Cloud, and tap Backup. Select what you want to back up and tap Back up now. You will need a Samsung account to use this service.

For documents and files, upload them to Google Drive, OneDrive, or Dropbox through the file manager or the app itself. These will stay in your cloud account and you can read them again after the reset.

Troubleshooting a stuck reset

If your tablet is stuck on the reset screen or the Samsung logo for more than twenty minutes, it may have frozen. Try a force restart: press and hold the Volume Down button and the Power button together for about ten seconds, then release. The tablet should vibrate and restart.

If the force restart does not work, plug the tablet into a computer with a USB cable and leave it plugged in for at least thirty minutes. This allows the battery to charge fully, which sometimes fixes a frozen reset. Then try the force restart again.

If the tablet still will not respond, the reset may have failed due to a hardware issue or corrupted software. At this point, contact Samsung support or visit a service center. Do not attempt to disassemble the tablet or try other fixes on your own.

Frequently Asked Questions

Will a factory reset remove my Google account?

The reset erases the account from the tablet, but the account itself still exists. When you set up the tablet after the reset, you can sign back in with the same Google account and your contacts, calendar, and synced photos will return.

Can I cancel a factory reset once it starts?

No. Once the reset begins, it will run to completion. This is why it is important to back up anything you want to keep before you start. Do not turn off the tablet during the reset.

What if I do not remember my Samsung account password?

Go to Samsung's account recovery page on a computer or another device, enter your email address, and follow the steps to reset your password. You will need access to the email address associated with the account. Once you reset the password, you can use it to sign in after the factory reset.

How long does a factory reset take?

Usually five to fifteen minutes, depending on how much data is on the tablet. Larger tablets with more storage may take longer. The tablet will restart automatically when it is done.

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

You do not need Wi-Fi to erase the data, but you will need it after the reset to sign in to your account and read apps. If you do not have Wi-Fi available, you can reset the tablet and set it up later when you have internet access.
