What a factory reset does and when you need one

A factory reset erases everything on your Samsung tablet — all apps, photos, files, accounts, 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, as if you'd just unboxed it.

You might need a factory reset if your tablet is running slowly, freezing often, or behaving erratically. It's also the right move if you're selling or giving away the device and want to remove your personal data. A reset can sometimes fix software problems that restarting alone won't solve.

Before you start, understand that this action cannot be undone. Back up anything you want to keep — photos, documents, contacts — to cloud storage like Google Drive, Samsung Cloud, or your computer. Once you begin the reset, those files will be gone from the tablet.

Key Takeaways

  • A factory reset wipes all data from your tablet and returns it to factory settings, so back up your files first.
  • You can reset through Settings on most Samsung tablets, or use hardware buttons if the tablet won't turn on or respond.
  • The process takes 5 to 15 minutes depending on how much data is on the device.
  • After reset, you'll need to sign in with a Google account or Samsung account to set up the tablet again.

Reset through Settings (the standard method)

If your tablet turns on and responds to touch, this is the easiest route. 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 you a summary of what will be deleted and ask you to confirm. Read it carefully — this is your final note to back out.

Tap the button to confirm (usually labeled Reset or Delete all). If you've set up a PIN, pattern, or password on the tablet, you may need to enter it to proceed. The tablet will then restart and begin the reset process. Do not turn it off or unplug it during this time.

The screen will go dark, show the Samsung logo, and display a progress bar. This can take anywhere from 5 to 15 minutes. When it finishes, you'll see the initial setup screen with language and Wi-Fi options, just as if the tablet were brand new.

Reset using hardware buttons (if the tablet won't respond)

If your tablet is frozen, won't turn on, or won't respond to touch, you can force a reset using the physical buttons on the device. The exact button combination depends on your model, but the most common method on Samsung tablets is to hold the Power button and Volume Up button together for 10 to 15 seconds.

Keep holding until the Samsung logo appears and the tablet vibrates. Then release both buttons. A menu with white text on a black background will appear — this is called Recovery mode.

Use the Volume Down button to highlight Wipe data/factory reset (or Factory reset). Press the Power button to select it. A confirmation screen will appear. Highlight Yes using Volume Down, then press Power to confirm. The reset will begin.

If this menu doesn't appear or the buttons don't work, your model may use a different combination. Check your tablet's model number (usually on the back) and search for "[your model] recovery mode buttons" to find the exact sequence.

What happens after the reset is complete

When the reset finishes, your tablet will restart and show the setup screen. You'll be asked to choose a language, connect to Wi-Fi, and sign in with a Google account. This account is required to use most Samsung tablets — you cannot skip this step.

If you remember the Google account you used before, sign in with that. If you don't, you can create a new one during setup. After you sign in, the tablet will read and reinstall your apps from the Google Play Store automatically, though this can take a while depending on how many apps you had.

Your photos, messages, and files will not return — they were permanently deleted during the reset. If you backed them up to Google Drive, Google Photos, or Samsung Cloud before the reset, you can read them again after setup is complete.

Preparing your tablet before a reset

The most important step is backing up your data. Open Settings, go to Accounts and backup or Accounts, and look for Backup and restore or Samsung Cloud. Sign in with your Samsung account and tap Back up data. Select what you want to save — contacts, messages, app data, and settings are common options.

For photos and videos, open the Gallery app, tap the menu (three dots or lines), and look for Settings or Cloud sync. Enable syncing to Google Photos or Samsung Cloud so your media is saved to the cloud.

If you have documents or files in folders, connect your tablet to a computer via USB cable and copy them to a folder on your computer. You can also upload them to Google Drive, OneDrive, or Dropbox through the tablet's file manager.

Write down any usernames and passwords you use on the tablet — you'll need them to sign back in after the reset. If you use two-factor authentication on any accounts, make sure you have access to the phone number or email address associated with those accounts.

Troubleshooting a stuck or failed reset

If the reset starts but the tablet gets stuck on the Samsung logo or a loading screen for more than 20 minutes, try a force restart. Hold the Power button for 10 seconds until the tablet vibrates and restarts. If it's still stuck, repeat the hardware button reset process from the beginning.

If you see an error message during reset, note what it says. Common errors include "E: failed to mount /cache" or "E: failed to mount /data" — these usually mean the tablet's storage is corrupted. Try the reset again. If the same error appears, the tablet may need professional service.

If the tablet resets successfully but won't let you sign in with your Google account, check that you're connected to Wi-Fi and that your account credentials are correct. If you've forgotten your Google password, use another device to visit accounts.google.com, click Sign in, and follow the recovery steps. Then try signing in on the tablet again.

When to call a professional instead

If your tablet won't turn on at all, doesn't respond to button presses, or shows error codes during reset, the problem may be hardware-related rather than software. A cracked screen, water damage, or a failing battery can prevent a reset from working.

If the reset completes but the tablet still freezes, crashes, or behaves erratically, there may be a deeper issue with the device's storage or processor. Contact Samsung support or visit an authorized repair center. Bring your proof of purchase if the tablet is still under warranty.

Frequently Asked Questions

Will a factory reset remove my Google account?

Yes, the reset removes your account from the tablet. However, your Google account itself still exists — you can sign back in with the same username and password after the reset. Your Google account data (email, contacts, calendar) will sync back to the tablet once you sign in again.

Can I cancel a factory reset once it starts?

No. Once you confirm the reset in Settings or select it in Recovery mode, the process cannot be stopped. This is why backing up your data first is so important. Do not turn off the tablet or remove the battery during the reset.

How long does a factory reset take?

Most resets take 5 to 15 minutes, depending on how much data is stored on the tablet. A nearly full tablet may take longer than an almost-empty one. The progress bar will show you how far along the process is.

Will a factory reset fix my tablet if it's running slowly?

Often yes, especially if the slowness is caused by too many apps, cached files, or conflicting software. However, if the tablet is slow because of a hardware problem — like a failing storage drive or overheating processor — a reset won't help. If it's still slow after the reset, the issue is likely hardware.

Do I need to charge my tablet before resetting?

Yes. Make sure your tablet has at least 50% battery before you start. If the battery dies during the reset, the tablet may not restart properly. Plug it in and let it charge fully before beginning.
