What a factory reset does and when to use it

A factory reset erases everything on your Samsung tablet — all apps, photos, messages, settings, and accounts — and returns it to the state it was in when it left the factory. This is useful when the tablet is running slowly, freezing often, or behaving erratically. It is also the right choice if you are selling or giving away the device and want to remove your personal data.

Before you reset, understand that this action cannot be undone. Everything will be gone. Back up any photos, documents, or other files you want to keep by transferring them to a computer, cloud storage, or an external drive. If you are signed into a Samsung or Google account on the tablet, write down your password — you will need it to sign back in after the reset.

Key Takeaways

  • A factory reset deletes all data on your tablet and returns it to its original state, so back up important files before you start.
  • You can reset through Settings by going to General Management, then Reset, then Factory Data Reset.
  • If your tablet is frozen or will not start, you can force a reset using hardware buttons — the method varies by model.
  • After the reset completes, you will need to sign back into your Samsung or Google account and reinstall your apps.
  • The reset process takes 5 to 15 minutes depending on how much data is on the device.

Reset through Settings (the standard method)

This method works when your tablet is responding normally. Open the Settings app, usually found on your home screen or in the app drawer. Scroll down and tap General Management (on some models this may be labeled System or About Device — look for the option that groups system-level settings).

Inside General Management, look for Reset or Reset Options. Tap it, then select Factory Data Reset or Reset All Settings. The tablet will show a warning that all data will be erased. Read it carefully, then tap the button to confirm — usually labeled Reset or Delete All. If you are signed into a Samsung account, you may be asked to enter your password to proceed. The reset will begin when ready and take 5 to 15 minutes. Do not turn off the tablet during this time.

When the reset finishes, the tablet will restart and show the initial setup screen, just as it did when new. You can now sign into your accounts and restore your data from backups.

Force a reset using hardware buttons (when the tablet is frozen)

If your tablet is frozen, unresponsive, or will not turn on, you can force a reset using a combination of physical buttons. The exact button combination depends on your model. For most Samsung tablets, hold down the Power button and Volume Up button together for 10 to 15 seconds until the Samsung logo appears or a recovery menu shows up.

If a recovery menu appears (usually with options in white text on a black background), use the Volume buttons to highlight Wipe Data/Factory Reset or Factory Data Reset, then press the Power button to select it. The tablet will ask you to confirm — highlight Yes and press Power again. The reset will proceed without erasing your Samsung account information, though you will still lose all apps and personal files.

Some Samsung models use different button combinations — for example, Power + Volume Down, or Power + Home + Volume Up. If the Power + Volume Up combination does not work, try Power + Volume Down. If neither works, check your tablet's model number (usually on the back) and search for "[your model number] factory reset buttons" to find the exact combination.

What happens after the reset is complete

Your tablet will restart and display the setup screen you saw when you first turned it on. You will be asked to select a language, connect to Wi-Fi, and sign into a Google account. Use the same Google account you had before the reset if you want to restore your apps and data from Google's backup.

After you sign in, the tablet will offer to restore apps and settings from your Google account backup. This process can take 10 to 30 minutes depending on how many apps you had. Your photos, contacts, and calendar events will return if they were backed up to Google Photos, Google Contacts, or Google Calendar. Apps that you purchased through the Google Play Store will reinstall automatically, but you will need to sign into any other accounts (email, social media, banking apps, etc.) manually.

If you had a Samsung account, sign into that as well — it may restore Samsung-specific settings and apps. Any files you backed up to a computer or external drive will need to be transferred back manually.

Common mistakes that cause problems

The most common mistake is resetting without backing up first. If you have photos, documents, or other files stored only on the tablet, they will be permanently lost. Before you reset, connect the tablet to a computer via USB cable and copy important files to a folder, or upload them to cloud storage like Google Drive, OneDrive, or Dropbox.

Another mistake is turning off the tablet during the reset. The process can take 15 minutes or longer, and interrupting it can leave the tablet in an unusable state. Plug the tablet into a charger before you start, and let it sit undisturbed until the setup screen appears.

A third mistake is forgetting your Google or Samsung account password. After the reset, you will be locked out of your account and unable to restore your apps and data. If you do not remember your password, visit the Google Account Recovery page or Samsung Account Recovery page on a computer before you reset, and follow the steps to regain access.

When to seek help instead of resetting

If your tablet is running slowly or freezing occasionally, try clearing the cache first — this is faster and safer than a full reset. Go to Settings, then Apps (or process Manager), select an app that is misbehaving, and tap Storage, then Clear Cache. Do this for a few apps at a time, then restart the tablet and see if performance improves.

If the tablet will not turn on at all and the hardware button method does not work, the device may have a hardware problem rather than a software one. In this case, contact Samsung support or visit a repair shop — attempting further resets could make the problem worse.

Frequently Asked Questions

Will a factory reset remove my Samsung account?

No. A factory reset removes your personal data and apps, but it does not remove your Samsung account from the device. You will still be able to sign in with the same account after the reset. However, if you want to completely remove the account, go to Settings, then Accounts, select your Samsung account, and tap Remove Account before you reset.

Can I undo a factory reset?

No, a factory reset cannot be undone. All data is permanently erased. This is why backing up before you reset is essential. If you have backed up your files to Google Drive, Google Photos, or another cloud service, you can restore them after the reset is complete.

How long does a factory reset take?

A factory reset usually takes 5 to 15 minutes from start to finish. If your tablet has a lot of data on it, it may take closer to 20 minutes. Do not turn off the device or remove the charger during this time.

What if I forget my Google password after the reset?

Visit the Google Account Recovery page on a computer and follow the steps to reset your password. You will need access to a recovery email or phone number associated with your account. Once you have reset your password, you can sign into your tablet with the new password.

Do I need to remove my SD card before resetting?

No. A factory reset only erases the tablet's internal storage, not files on an SD card. However, if you want to be extra safe, you can remove the SD card before resetting and reinsert it afterward. Any files on the card will remain untouched.
