What a factory reset does and when you need one

A factory reset erases everything on your Samsung tablet and returns it to the state it left the factory — all apps you installed, photos, documents, messages, and settings are deleted. The operating system itself stays the same. You would do this if the tablet is running slowly, freezing often, or you are selling it and want to remove your personal data before handing it over.

A factory reset is different from a straightforward restart. A restart clears the tablet's temporary memory and often fixes minor glitches. A factory reset is permanent and should be your last step after trying a restart and clearing the cache. Once you start a factory reset, you cannot stop it partway through.

Before you reset, back up anything you want to keep. Samsung tablets can back up to a Samsung account, Google account, or a computer. If you do not back up first, that data is gone.

Key Takeaways

  • A factory reset deletes all your apps, photos, documents, and settings, so back up anything you want to keep before you start.
  • You can back up to a Samsung account, Google account, or connect the tablet to a computer via USB cable.
  • The reset process takes 5 to 15 minutes and the tablet will restart several times — do not turn it off during this time.
  • After the reset completes, you will see the initial setup screen as if the tablet is brand new.

Back up your data before resetting

Open Settings and tap Accounts and backup (the exact name varies slightly by model and Android version, but it is always in Settings). Look for an option that says Back up my data or Samsung Cloud. If you use a Samsung account, sign in and toggle the backup on. The tablet will back up your contacts, calendar, messages, and some app data to Samsung's servers.

If you prefer to use Google instead, go to Settings > Google > Manage your Google Account > Data & Privacy and turn on Web & App Activity. This backs up fewer things than Samsung Cloud, but it is tied to your Google account, which you will set up again after the reset anyway.

For photos and documents, connect the tablet to a computer with a USB cable. The tablet will appear as a removable drive. Drag your files to a folder on your computer. This is the safest method if you have large files or anything you absolutely cannot lose.

How to factory reset through Settings

This is the standard method and works on all Samsung tablets. Open Settings and scroll down to find General management or System (the name depends on your Android version). Tap it, then look for Reset or Reset options.

You will see several reset choices. Tap Factory data reset or Erase all data. The tablet will show you a warning that all data will be deleted. Read it, then tap Reset or Delete all to confirm. You may be asked to enter your PIN, pattern, or password — this is a safety step to prevent accidental resets.

The reset will begin. Your tablet will restart, show a progress bar, and restart again. This can take 5 to 15 minutes. Do not turn off the tablet, remove the battery, or disconnect the charger during this time. When it finishes, you will see the initial setup screen.

How to factory reset if you cannot access Settings

If your tablet is frozen, will not turn on, or you cannot get to Settings, you can force a reset using hardware buttons. The button combination varies by model, but for most Samsung tablets it is: hold the Power button and Volume Up button together until the Samsung logo appears, then release. The tablet will boot into recovery mode.

Use the volume buttons to navigate to Wipe data/factory reset and press the Power button to select it. Confirm the reset when prompted. Again, do not interrupt this process. It will take several minutes and the tablet will restart multiple times.

If the button combination does not work for your specific model, look up your tablet's model number (usually on the back) and search for "[your model] factory reset buttons" to find the correct combination.

What happens after the reset completes

When the reset finishes, your tablet will boot into the initial setup screen, just as if it came from the box new. You will be asked to choose a language, connect to Wi-Fi, and sign in to a Google account. If you backed up to a Samsung account, you can sign in with that account and restore your data during setup. If you backed up to Google, your contacts and calendar will restore automatically when you sign in.

After setup, your tablet will be clean and fast. Apps you installed are gone, but the built-in Samsung and Google apps remain. If you backed up photos and documents to your computer, you can reconnect the tablet via USB and copy them back.

Troubleshooting a reset that goes wrong

If the tablet gets stuck on the Samsung logo or a progress bar for more than 30 minutes, it may have encountered an error. Try a force restart: hold the Power button for 10 seconds until the screen goes black, then release and turn it back on. If it still does not respond, try the hardware button reset method described above.

If the reset completes but the tablet will not turn on, or keeps restarting in a loop, the operating system may be corrupted. This is rare but can happen if the tablet loses power during the reset. In this case, you will need to contact Samsung support or visit a service center — they can reinstall the operating system using specialized tools.

When to call a professional instead

If your tablet is physically damaged, has a cracked screen, or will not charge, a factory reset will not fix it. If the tablet overheats, smells like burning plastic, or the battery is swollen, do not attempt a reset — turn it off and contact Samsung or a repair shop.

If you have forgotten your Google account password or the PIN you set up on the tablet, you may not be able to complete the reset without proving your identity to Google. This is a security feature. You can recover your Google account through Google's account recovery page, but it can take time. If you are stuck, Samsung support can walk you through the options.

Frequently Asked Questions

Will a factory reset remove the operating system?

No. A factory reset removes only the apps and data you added after you got the tablet. The Android operating system stays in place. Your tablet will still run the same version of Android it had before the reset.

Can I stop a factory reset once it starts?

No. Once you confirm the reset in Settings or recovery mode, it cannot be stopped. This is why backing up first is so important. If you realize you made a mistake, turn off the tablet when ready — but even then, some data may already be erased.

How long does a factory reset take?

Most factory resets take 5 to 15 minutes from start to finish, including the restarts. Older tablets or those with a lot of storage may take longer. The progress bar will show you how far along the reset is.

Do I need to charge the tablet before resetting?

Yes. Make sure the battery is at least 50 percent charged before you start. If the tablet runs out of power during the reset, the operating system can become corrupted and the tablet may not turn on again. Plug it in and let it charge fully before you begin.

What if I forgot to back up my photos?

Once a factory reset completes, your photos are gone and cannot be recovered through normal means. This is why backing up before you reset is critical. For the future, use Google Photos or Samsung Cloud to back up automatically — both services back up as you take photos, so you do not have to remember to do it manually.
