What a Factory Reset Does and When You Need One

A factory reset erases everything on your Samsung tablet—all apps, photos, messages, files, and settings—and returns it to the state it was in when it left the factory. After the reset completes, you'll see the initial setup screen, the same one you saw when you first turned on the tablet.

You might reset your tablet if it's running slowly, freezing frequently, or behaving unpredictably. A reset also removes malware or unwanted apps that won't uninstall normally. If you're selling or giving away the tablet, a factory reset ensures the new owner doesn't inherit your personal data.

Before you start, back up anything you want to keep. Photos, documents, and other files will be gone after the reset. If you use a Samsung account, your contacts and some settings can be restored afterward, but apps and their data will not.

Key Takeaways

  • Back up your photos, files, and documents before starting, because a factory reset deletes everything on the tablet.
  • You can reset through Settings on the tablet itself, or through Find Mobile (Samsung's remote service) if the tablet won't turn on or respond.
  • The reset process takes 10 to 30 minutes depending on how much data is on the tablet.
  • After the reset, you'll need to sign in with a Samsung account or Google account to set up the tablet again.
  • If you're locked out by a Samsung account password, you'll need that password to proceed past the setup screen after the reset.

Back Up Your Data Before You Start

The easiest way to back up is through your Samsung account. Go to Settings > Accounts and backup > Samsung account, then tap Backup. This saves your contacts, calendar, and some app data to Samsung's servers. After the reset, you can sign in and restore these items.

For photos and videos, open the Gallery app, tap the menu (three lines or three dots), and look for a backup or cloud option. You can also connect the tablet to a computer with a USB cable and copy files manually to your computer's hard drive. If you use Google Photos, it can back up your photos automatically if you have it installed.

For documents and other files, check whether they're stored in Google Drive, OneDrive, or another cloud service. If they're only on the tablet's internal storage, copy them to your computer or upload them to a cloud service before you reset.

Reset Through Settings (The Standard Method)

This method works if your tablet turns on and responds normally. Open Settings and scroll down to find General management or System (the exact name varies by model and Android version). Tap it.

Look for Reset or Reset options. Tap Factory data reset or Erase all data. The tablet will show a warning listing what will be deleted. Read it, then tap Reset or Delete all to confirm.

If the tablet asks for your Samsung account password or PIN, enter it. This is a security step to prevent someone else from erasing your tablet without permission. The reset will then begin. Do not turn off the tablet or remove the battery during this time. The process usually takes 10 to 30 minutes. When it finishes, the tablet will restart and show the initial setup screen.

Reset Using Find Mobile (If the Tablet Won't Respond)

If your tablet is frozen, won't turn on, or won't respond to touch, you can reset it remotely through Find Mobile, Samsung's device management service. Go to findmobile.samsung.com on a computer and sign in with the Samsung account that's linked to the tablet.

Select your tablet from the list of devices. Look for an option called Unlock, Erase, or Factory reset—the exact wording depends on your account interface. Confirm the action. The tablet will receive the command the next time it connects to the internet, even if it's currently off. When it restarts, it will begin the reset process.

This method requires that you remember your Samsung account password and that the tablet is registered to that account. If you don't have access to the account, you'll need to contact Samsung support or take the tablet to a Samsung service center.

Reset Using Hardware Buttons (If Settings Won't Open)

If your tablet won't start normally or Settings won't open, you can force a reset using the power and volume buttons. The exact button combination varies 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 the recovery menu opens.

If a menu appears with options like "Reboot system now" or "Wipe data/factory reset," use the volume buttons to highlight Wipe data/factory reset and press the Power button to select it. Confirm the action. The tablet will reset and restart.

If you're not sure which buttons to hold, search online for "[your tablet model] factory reset button combination." Different models use different combinations, and pressing the wrong buttons might not work or might do something else entirely.

What Happens After the Reset

When the tablet restarts, it will show the initial setup screen in English (or the language set at the factory). You'll be asked to select a language, connect to Wi-Fi, and sign in with a Google account or Samsung account. If you have a Samsung account, signing in will restore your backed-up contacts and calendar. You'll need to reinstall your apps from the Google Play Store or Samsung Galaxy Store.

If the tablet is locked by a Samsung account (a security feature called Reactivation Lock), you'll need to enter the password for that account to proceed. If you don't remember the password, you can reset it at account.samsung.com on a computer, or contact Samsung support for help.

After setup is complete, the tablet should run noticeably faster if slowness was the reason for the reset. If problems persist, the issue may be hardware-related rather than software-related, and you may need to contact Samsung support or take the tablet to a service center.

Common Mistakes to Avoid

Do not turn off the tablet or remove the battery while the reset is running. This can corrupt the system and leave the tablet unable to start. Let the process finish completely, even if it seems to be taking a long time.

Do not assume you can skip the backup step. Once the reset starts, your data is gone. There is no undo button. If you realize after the reset that you needed something, recovery is difficult and often impossible.

Do not forget your Samsung account password if the tablet uses Reactivation Lock. You will not be able to set up the tablet after the reset without it. If you're not sure, reset your password at account.samsung.com before you start the factory reset.

Frequently Asked Questions

Will a factory reset remove viruses or malware?

Yes. A factory reset erases everything on the tablet, including any malware. However, if you reinstall the same app that contained the malware, you'll get infected again. After the reset, be careful about which apps you install and only read from the official Google Play Store or Samsung Galaxy Store.

Can I recover files after a factory reset?

Recovery is very difficult and often unsuccessful. Once the reset completes, the data is overwritten as you use the tablet. If you need to recover something, stop using the tablet when ready and contact a data recovery service, though they are expensive and not may provide to work. This is why backing up before the reset is essential.

What if I'm locked out by a Samsung account password after the reset?

You'll need to reset your Samsung account password at account.samsung.com on a computer. If you don't have access to the email address linked to the account, contact Samsung support. They may ask you to verify your identity before they help you regain access.

How long does a factory reset take?

Most resets take 10 to 30 minutes, depending on how much data is on the tablet. A tablet with very little data might finish in 10 minutes. A tablet full of apps and files might take 30 minutes or longer. Do not interrupt the process.

Do I need Wi-Fi to reset my tablet?

You don't need Wi-Fi to start the reset, but you'll need it during the setup process afterward to sign in to your accounts and read apps. If you don't have Wi-Fi available, you can complete the reset and set up the tablet later when you have internet access.
