What a factory reset does and when to use it

A factory reset erases all data on your Galaxy tablet and returns it to the state it was in when it left the factory. This means your apps, photos, files, passwords, and accounts all disappear. The operating system itself stays the same version, but every personal setting and piece of content you added gets removed.

You should reset your tablet if it runs slowly, freezes often, has a virus or malware, or you plan to sell or give it away. If you just want to delete a few apps or clear space, a reset is overkill—you can uninstall apps or clear the cache instead. Before you reset, back up anything you want to keep: photos, documents, contacts, and any data from apps you care about.

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 by going to General Management, then Reset, then Factory Data Reset.
  • If your tablet is frozen or won't turn on, you can force a reset using the power and volume buttons together.
  • After the reset completes, you will need to sign in with your Samsung account and set up the tablet again from scratch.
  • The reset process takes 5 to 15 minutes depending on how much data is on the tablet.

Reset through Settings (the normal way)

This method works when your tablet turns on and responds normally. Open the Settings app—usually a gear icon on your home screen or in the app drawer. Scroll down and tap General Management. Look for Reset and tap it.

You will see several reset options. Tap Factory Data Reset. The tablet will show you a warning that all data will be erased and ask you to confirm. Read it carefully. Tap Reset or Delete All (the exact wording varies by model). If your tablet is password-protected, you may need to enter your PIN, pattern, or password before it proceeds.

The tablet will restart and begin erasing data. You will see a progress bar. Do not turn off the tablet or remove the battery during this time. The process usually takes 5 to 15 minutes. When it finishes, the tablet will restart and show the initial setup screen, as if it were brand new.

Force reset when the tablet is frozen or won't respond

If your Galaxy tablet is completely frozen, won't turn on, or does not respond to touch, you can force a reset using the hardware buttons. The exact button combination depends on your model, but the most common is holding the Power button and Volume Down button together for 10 to 15 seconds.

Keep holding both buttons until you see the Samsung logo or a recovery menu appear. This may take longer than you expect—keep holding. Once the menu appears, release the buttons. You will see options like "Reboot System Now" or "Wipe Data/Factory Reset." Use the volume buttons to move up and down, and the power button to select. Highlight Wipe Data/Factory Reset and press the power button to confirm.

The tablet will erase data and restart. This process is more disruptive than a normal reset because the tablet is not running normally, but it works when nothing else does. Again, do not interrupt the process—let it finish completely.

What to do after the reset is complete

When the tablet restarts after a factory reset, it will show the setup screen you saw the first time you turned it on. You will be asked to choose a language, connect to Wi-Fi, and sign in with a Google account. You must sign in with a Google account to use most Galaxy tablet features.

If you have a Samsung account, you can also sign in with that to restore some settings and apps you had before. However, your personal files, photos, and documents will not come back unless you restored them from a backup before the reset. If you backed up to Google Drive, OneDrive, or Samsung Cloud before resetting, you can read those files after you sign in.

Reinstall any apps you need from the Google Play Store. This takes time if you had many apps, so be patient. Your tablet is now clean and should run faster than before.

Back up your data before resetting

The safest way to back up a Galaxy tablet is to use Samsung Cloud or Google Drive. For Samsung Cloud, open Settings, go to Accounts and Backup, and tap Samsung Cloud. Sign in with your Samsung account and choose what to back up: contacts, calendar, messages, and some app data. Tap Back Up to start.

For Google Drive, open the Google Drive app, tap the menu (three lines), go to Settings, and choose which folders to back up automatically. Photos and videos can also be backed up through Google Photos—open the app, tap your profile picture, go to Photos Settings, and turn on Backup and Sync.

For files and documents, connect your tablet to a computer with a USB cable and copy files to your computer's hard drive. This is the most reliable method for large amounts of data. Take a few minutes to do this before you reset—it takes far less time than trying to recover data afterward.

Common mistakes to avoid

Do not interrupt a reset once it has started. Turning off the tablet, removing the battery, or unplugging it during a reset can damage the system and make the tablet unusable. Let the process finish completely, even if it seems to be taking a long time.

Do not assume you can undo a reset. Once the data is gone, it is gone. There is no "undo" button. If you have not backed up your photos, contacts, or files, they will be lost forever. Take the time to back up before you reset.

Do not reset just to free up storage space. A reset will free up space, but so will uninstalling apps you do not use, clearing the cache, and deleting old files. If your tablet is running out of space, try these steps first. Only reset if the tablet is slow or has other problems that clearing space will not fix.

Frequently Asked Questions

Will a factory reset remove the password from my tablet?

Yes. A factory reset erases all passwords, PINs, and patterns. After the reset, you will set up a new password during the initial setup. However, you will still need to sign in with your Google account, which requires the password to that account.

Can I reset my Galaxy tablet if it is locked with a PIN I forgot?

Yes, but you will need to sign in with your Google account after the reset. If you forgot your Google password as well, you will need to recover that account first through Google's account recovery page on a computer before you can use the tablet again.

How long does a factory reset take?

Most factory resets take 5 to 15 minutes, depending on how much data is on the tablet and how old the tablet is. Older tablets or those with a lot of data may take longer. Do not turn off the tablet during this time.

Will my apps come back after a reset?

No, you will need to reinstall them from the Google Play Store. However, if you signed in with the same Google account you used before, some app data may be restored automatically. You will still need to read the apps themselves.

What if my tablet still does not work after a factory reset?

If the tablet still has problems after a reset, the issue may be a hardware problem rather than a software one. Contact Samsung support or visit a repair shop. Do not attempt multiple resets—one is usually enough.
