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 restores it to the state 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 no personal information remains. If you forgot your PIN or password and cannot get past the lock screen, a reset is sometimes the only way forward — though Samsung has added protections that make this harder than it used to be.

Before you start, understand that this action cannot be undone. Back up anything you want to keep: photos, documents, contacts, and any data from apps you care about. If you have a Samsung account linked to the tablet, sign out of it first, or you may be locked out after the reset.

Key Takeaways

  • A master reset erases all personal data and returns your tablet to factory settings, and the process cannot be reversed.
  • Back up your photos, documents, contacts, and app data before starting, because everything will be deleted.
  • The easiest method is through Settings > General Management > Reset > Factory Data Reset, which takes 5 to 15 minutes.
  • If you are locked out of your tablet, you may need to use Samsung Find Mobile or contact Samsung Support, because newer tablets require your Samsung account password after a reset.
  • After the reset completes, your tablet will restart and ask you to set it up as if it were new.

How to Reset Through Settings (The Standard Method)

This is the most straightforward path if you can unlock your tablet and access the Settings app. Open Settings by swiping down from the top of the screen twice to open the Quick Settings panel, then tap the Settings icon (usually a gear). Alternatively, find Settings in your app drawer.

Once Settings is open, scroll down and tap General Management. The exact name varies slightly by model and Android version — you might see "System" or "About Phone" instead on some tablets. Inside General Management, look for Reset or Reset Options. Tap it, then select Factory Data Reset or Erase All Data.

The tablet will show you a warning listing what will be deleted. Read it, then tap Reset or Delete All to confirm. You may be asked to enter your PIN, password, or Samsung account password as a final safety check. After you confirm, the tablet will restart and begin the reset process. This usually takes 5 to 15 minutes. Do not turn off the tablet during this time.

Resetting a Tablet Locked by a Forgotten Password

If you cannot unlock your tablet because you forgot the PIN or password, you have limited options. Samsung tablets made in the last few years require your Samsung account credentials after a factory reset, so straightforward wiping the device does not get you back in.

Your best option is Samsung Find Mobile (findmobile.samsung.com). Sign in with the Samsung account that is linked to the tablet. If you remember the account email and password, you can use Find Mobile to remotely lock, locate, or wipe the tablet. After a remote wipe, the tablet will ask for the Samsung account password when it restarts — so you must know that password to proceed.

If you do not have a Samsung account linked to the tablet, or you do not remember the account password, contact Samsung Support directly. They can verify ownership and may be able to help you regain access. Have your proof of purchase or the tablet's serial number ready. This process is slower than a self-service reset, but it is the legitimate path when you are locked out.

Using Recovery Mode for a Stuck or Unresponsive Tablet

If your tablet will not turn on, is frozen on the startup screen, or will not respond to normal commands, you can force a reset using Recovery Mode. This method works even if the tablet is not responding to touch or buttons.

First, turn off the tablet completely. If it is frozen, hold the Power button for 10 to 15 seconds until it shuts down. Once it is off, press and hold the Power button and the Volume Up button at the same time. Keep holding both buttons until the Samsung logo appears, then release them. The tablet will enter Recovery Mode, showing a menu with white text on a black background.

Use the Volume Down button to navigate to Wipe Data/Factory Reset and press the Power button to select it. The tablet will ask you to confirm by selecting Yes — use Volume Down to highlight it and Power to confirm. The reset will begin. Do not interrupt it. When it finishes, the menu will return. Select Reboot System Now to restart the tablet.

What Happens After the Reset Completes

When your tablet restarts after a master reset, it will look and feel like a brand-new device. You will see the initial setup screen, which asks you 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 accounts you used before, but using your Google account is helpful because it can restore some app data and settings that were backed up to Google's servers.

After setup, your tablet will be empty. Your apps are gone, so you will need to read them again from the Google Play Store or Samsung Galaxy Store. Any photos, videos, or documents that were stored only on the tablet are permanently deleted. If you backed them up to Google Photos, OneDrive, or another cloud service before the reset, you can read them again.

Take your time setting the tablet back up. Install only the apps you actually use, and avoid rushing through security settings. If you are setting up a tablet to give to someone else, stop after the reset and before the setup — let the new owner complete the setup with their own account.

Backing Up Before You Reset

The time to back up is before you start the reset, not after. Open Settings and look for Accounts and Backup or Cloud and Accounts. Tap Samsung Cloud or Google Account and make sure backup is turned on. Let it run to completion — this may take several minutes if you have a lot of data.

For photos and videos, open the Google Photos app and make sure it is set to back up your library. You can also manually copy files to a computer using a USB cable, or upload them to OneDrive, Dropbox, or another cloud storage service. For contacts, make sure they are synced to your Google account or Samsung account — open Contacts, tap the menu, and look for an option to export or sync.

If you use apps that store important data locally (like note-taking apps, banking apps, or fitness trackers), check each app's settings for a backup or export option. Some apps let you export data as a file you can save to cloud storage. Taking 20 minutes to back up now saves hours of frustration later.

Troubleshooting a Reset That Does Not Work

Occasionally a reset fails or gets stuck. If the tablet is frozen on the reset screen for more than 30 minutes, try a hard restart: hold the Power button for 10 to 15 seconds until the screen goes black, then wait 30 seconds and turn it back on. This does not undo the reset — it just restarts the tablet if the process stalled.

If the tablet keeps restarting in a loop or will not get past the setup screen, the reset may not have completed properly. Try entering Recovery Mode again and running the reset a second time. If that does not work, the tablet may have a hardware problem or corrupted system files that a factory reset cannot fix. At that point, contact Samsung Support or visit a service center.

If you reset the tablet and now cannot sign back in because you forgot your Samsung account password, use the Samsung account password recovery tool at account.samsung.com. You will need access to the email address or phone number linked to the account. This process usually takes a few minutes.

Frequently Asked Questions

Will a master reset remove the Android operating system?

No. A master reset only removes your personal data and apps. The Android operating system and Samsung's system apps stay in place. Your tablet will still run the same version of Android it ran before the reset.

Can I undo a master reset after it is done?

No, a master reset cannot be undone. Once the data is erased, it is gone unless you backed it up beforehand. This is why backing up before you reset is so important.

Do I need to remove my Samsung account before resetting?

It is a good idea to sign out of your Samsung account before resetting, especially if you are giving the tablet to someone else. If you do not sign out, the new owner will be locked out after the reset and will need your Samsung account password to proceed. If you forget to sign out, you can use Samsung Find Mobile to remove the account remotely.

How long does a master reset take?

A typical master reset takes 5 to 15 minutes from start to finish. Larger tablets with more storage may take longer. Do not turn off the tablet or interrupt the process while it is running.

What if my tablet is stuck on the lock screen and I cannot access Settings?

Use Recovery Mode to force a reset. Hold Power and Volume Up together until the Samsung logo appears, then navigate to Wipe Data/Factory Reset using the Volume buttons and Power button to select. This works even if the tablet is completely unresponsive to normal touch commands.
