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 returns it to the state it left the factory. This means all your apps, photos, videos, messages, contacts, and settings disappear. The operating system itself stays intact—you are not removing Android or Samsung's software, just the data and customizations you added after you unboxed it.

You should master reset your tablet if it is running slowly, freezing constantly, or behaving erratically in ways that restarting has not fixed. A reset also helps if you are selling or giving away the tablet and want to make sure no personal information remains on it. If you forgot your Samsung account password or PIN and cannot get past the lock screen, a reset may be your only way forward—though Samsung has added protections that make this harder than it used to be.

Before you reset, back up anything you want to keep. Photos, documents, and other files can be copied to a cloud service like Google Drive or Samsung Cloud, or transferred to a computer via USB cable. Once you start the reset, there is no undo button.

Key Takeaways

  • A master reset wipes all your personal data and returns the tablet to factory settings, but you should back up important files first.
  • You can reset through Settings on most Samsung tablets, or use hardware buttons if the tablet will not turn on or respond to touch.
  • If you are locked out by a Samsung account, the tablet will ask you to sign back in after the reset—you will need that password to proceed.
  • A reset takes 10 to 30 minutes depending on how much data is on the tablet; do not interrupt it or remove power.
  • If the tablet still does not work after a reset, the problem is likely hardware-related and you should contact Samsung support or a repair shop.

Reset Through Settings (The Standard Method)

This is the easiest path if your tablet turns on and responds to touch. Open Settings and scroll down to find General Management or System—the exact name varies by tablet model and Android version. Tap it, then look for Reset or Reset Options.

You will see Factory Data Reset or Reset to Factory Settings. Tap it. 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 to proceed. The tablet will restart and begin wiping itself. This usually takes 10 to 30 minutes. Do not turn it off, unplug it, or interrupt the process—if power cuts out mid-reset, you may end up with a tablet that will not start.

When the reset finishes, the tablet will restart and show you the initial setup screen, the same one you saw when you first turned it on. You can now set it up as a new device or sign into your Samsung account to restore some settings and apps.

Reset Using Hardware Buttons (If the Tablet Is Frozen or Locked)

If your tablet will not respond to touch, is stuck in a boot loop, or is locked and you cannot reach Settings, you can force a reset using the power and volume buttons. The exact button combination varies slightly by model, but the most common is: hold the Power button and Volume Up button together for 10 to 15 seconds until the Samsung logo appears or a menu shows up.

Release the buttons. You should see a screen with options in white text on a black background. This is called recovery mode. Use the volume buttons to navigate and the power button to select. Look for an option like Wipe Data / Factory Reset or Factory Reset. Highlight it and press power to select it. The tablet will ask you to confirm—select Yes. The reset will begin. This can take longer than a Settings reset, sometimes 30 to 45 minutes.

If you do not see a recovery menu and instead see a boot animation or the Samsung logo, try the button combination again. If the tablet has a physical Home button, some models use Power + Home + Volume Up instead. Check your tablet's model number (usually on the back) and search for "[Your Model] recovery mode" if the first combination does not work.

What Happens After Reset: Samsung Account Lock

After the reset completes and the tablet restarts, it will ask you to sign in. If you previously set up a Samsung account on this tablet, you will need to sign back in with that account's email and password. This is called Reactivation Lock or Find My Mobile protection, and Samsung uses it to prevent theft.

If you remember your Samsung account password, sign in and you are done. If you do not remember it, you can reset the password through Samsung's website before you reset the tablet, or you can use a recovery email or phone number linked to the account to regain access. If you do not have access to the account at all, you will be stuck at this screen. Contact Samsung support with proof of purchase—they can sometimes help you regain access or remove the lock.

If the tablet was not previously linked to a Samsung account, it will skip this step and go straight to the Google account sign-in screen. You can sign in with any Google account, or skip this step and set up the tablet later.

Backing Up Your Data Before You Reset

The safest approach is to back up your important files before you reset. If your tablet is still responsive, open Settings, find Accounts, and look for Samsung Account or Google Account. Tap it and look for a Backup or Sync option. This will copy your contacts, calendar, and some app data to the cloud.

For photos and videos, open the Gallery app and look for a backup option, or use Google Photos—it can back up your entire photo library to your Google account automatically. For documents, use Google Drive or OneDrive to upload files you want to keep.

If the tablet is not responding well enough to do this, you can connect it to a computer via USB cable and copy files manually. On a Windows computer, the tablet will appear as a removable drive in File Explorer. On a Mac, you may need to install Android File Transfer first. Copy your photos, videos, and documents to a folder on your computer, then proceed with the reset.

Troubleshooting: What to Do If the Reset Does Not Fix the Problem

If your tablet still runs slowly, freezes, or behaves oddly after a factory reset, the problem is likely not software—it is probably a hardware issue. A reset removes all apps and data, so if the problem persists, it points to a failing storage drive, a battery that no longer holds charge, or a hardware component that is failing.

At this point, contact Samsung support through their website or call their customer service line. Have your tablet's model number ready (usually on the back or in Settings under About Device). They can walk you through additional troubleshooting or arrange a repair. If your tablet is still under warranty, the repair may be free or low-cost. If it is out of warranty, ask for a repair estimate before you authorize any work.

If you do not want to go through Samsung, a local phone or tablet repair shop can often diagnose and fix hardware problems. Get a quote from at least two shops before deciding, and ask whether they can recover any data if the storage drive is failing.

Frequently Asked Questions

Will a master reset remove the Samsung operating system?

No. A master reset only erases your personal data and settings. The Android operating system and Samsung's software stay on the tablet. After the reset, the tablet will still run the same version of Android it had before.

Can I stop a reset once it has started?

You should not interrupt a reset once it begins. If you turn off the tablet or unplug it mid-reset, you risk corrupting the system and making the tablet unusable. Let it finish, even if it takes 30 minutes or longer. If the reset seems to be taking much longer than an hour, the tablet may have frozen—wait another 10 minutes, then try a hard restart by holding the power button for 30 seconds.

What if I do not remember my Samsung account password after the reset?

Go to Samsung's Find My Mobile website and use the password reset option. You will need to verify your identity using a recovery email or phone number. If you do not have access to those either, contact Samsung support with proof of purchase—they can help you regain access to the account or remove the lock so you can use the tablet.

How long does a master reset take?

A typical reset takes 10 to 30 minutes. Tablets with a lot of data or older models may take longer. Do not turn off the tablet or remove power during this time. The screen may go black or show a progress bar—this is normal.

Will I lose my apps after a reset?

Yes, all apps you installed will be removed. However, if you sign into your Google account after the reset, Google Play will remember which apps you had installed and offer to reinstall them automatically. Apps you purchased will still be in your account and can be reinstalled for free.
