What a factory reset does and when you need one
A factory reset wipes your Samsung Galaxy tablet back to the state it left the factory — all your apps, photos, messages, and settings are removed. The operating system stays the same, but everything you added or changed is gone. You should back up anything you want to keep before you start.
People reset tablets for a few reasons: the device is running slowly and clearing out accumulated data helps, you are selling or giving away the tablet and want to erase your personal information, you forgot your PIN or password and need a way back in, or an app is crashing repeatedly and a fresh start fixes it.
A reset takes 10 to 30 minutes depending on how much data is on the device. Your tablet will restart several times during the process. Plug it in before you begin — if the battery dies mid-reset, you may have serious problems restarting it.
Key Takeaways
- Back up your photos, documents, and any data you want to keep before starting, because a factory reset removes everything except the operating system.
- You can reset through Settings on most Samsung tablets, or use the hardware button combination if you cannot access Settings.
- If you are locked out by a forgotten PIN, you may be able to reset using your Samsung account or Google account instead of wiping everything.
- The reset process takes 10 to 30 minutes and requires a full battery charge or a plugged-in power adapter.
- After the reset completes, your tablet will restart and ask you to set up as if it were new — you will need to sign in to your accounts again.
Backing up your data before you reset
The fastest way to back up a Samsung tablet is through your Samsung account. Go to Settings > Accounts and backup > Samsung account and sign in. Tap Backup and choose what you want to save — photos, contacts, messages, app data, and settings all have separate toggles. The backup uploads to Samsung's servers and you can restore it after the reset.
If you use Google services, your Google account already backs up some things automatically: Gmail, Google Drive files, Google Photos, and contacts linked to your Google account. You do not need to do anything extra for those. If you have photos or files stored only on the tablet itself, move them to Google Drive or Google Photos before you reset.
For documents or files in other apps, check whether those apps have their own backup or sync options. Microsoft OneDrive, Dropbox, and similar services let you upload files directly from the app. If you use a banking app or other sensitive account, write down your username and recovery codes before you reset — you will need them to sign back in.
Resetting through Settings if you can access your tablet
Open Settings and scroll down to find General management (on some models it is called System). Tap it, then look for Reset or Reset options. You will see Reset all settings and Erase all data — choose Erase all data (also called Factory data reset or Format device depending on your model and Android version).
The tablet will ask you to confirm. It may also ask for your PIN, password, or Samsung account password as a security check — this prevents someone else from wiping your device without permission. Enter it and tap the button to start the reset. Your tablet will restart and show a progress bar. Do not turn it off or unplug it during this time.
When the reset finishes, your tablet restarts and shows the initial setup screen, the same one you saw when you first turned it on. You can now sign in to your accounts and restore your backup if you created one.
Resetting using hardware buttons if Settings is not accessible
If your tablet is frozen, will not turn on, or you cannot reach Settings, you can force a reset using the power and volume buttons. The exact combination varies by model, but the most common method on Samsung tablets is: turn off the tablet completely, then hold the Power button and Volume Up button together until the Samsung logo appears (usually 10 to 15 seconds). Release both buttons.
Your tablet enters Recovery mode, which shows a menu with options in white text on a black background. Use the Volume Down button to scroll to Wipe data/factory reset and press the Power button to select it. A confirmation screen appears — scroll to Yes and press Power again. The reset begins and takes several minutes.
If the button combination does not work on your model, search online for "[your exact tablet model] recovery mode" — Samsung uses slightly different combinations for different tablets. Some newer models use a different method entirely, so checking your specific model saves frustration.
Getting back in if you forgot your PIN or password
If you are locked out of your tablet, you have options before you resort to a full factory reset. After you enter the wrong PIN or password several times, the tablet offers Forgot password? or Forgot PIN? — tap it. You will be asked to sign in with your Samsung account or Google account instead. If you remember either of those passwords, you can unlock the tablet without erasing anything.
If you do not remember your Samsung account password, go to the Samsung account website on a computer and use the password reset tool there. If you do not remember your Google account password, use Google's account recovery page. Once you reset the password on a computer, come back to your tablet and try signing in again with the new password.
If you cannot recover either account, a factory reset is your only way forward. Use the hardware button method described above since you cannot access Settings. After the reset, you will set up the tablet fresh and can create new accounts.
What to do after the reset is complete
Your tablet restarts and shows Welcome or Hello with language and region options. Go through the setup steps: choose your language and region, connect to Wi-Fi, and sign in to your Google account (you will need this to read apps from the Google Play Store). You will also be offered the chance to restore from a backup — if you created a Samsung account backup before the reset, choose Restore and sign in to your Samsung account to bring back your photos, contacts, and settings.
After setup finishes, your tablet is ready to use. If you backed up to Google services, your Gmail, Drive files, and Google Photos will sync back automatically once you sign in. Apps you had before will not reinstall on their own — you can read them again from the Google Play Store, but you will need to sign in to any accounts those apps use (banking apps, social media, email, etc.).
If the tablet is still slow or crashing after the reset, the problem may be hardware-related rather than software. Try using it for a few days to see if performance improves as the system settles. If problems persist, contact Samsung support or visit a repair shop.
Frequently Asked Questions
Will a factory reset remove the Android operating system?
No. A factory reset only removes your personal data, apps, and settings. The Android operating system that came with your tablet stays in place. Your tablet will work exactly as it did when you first bought it, except without your accounts and files.
Can I stop a factory reset once it starts?
Not safely. Once the reset process begins, stopping it mid-way can damage the tablet's system files and make it unusable. Always plug in your tablet and make sure the battery is full before you start. If the tablet loses power during a reset, you may need to contact Samsung support to recover it.
What if I restore my backup and the problem comes back?
If the tablet was slow or crashing before the reset, and the problem returns after you restore your backup, the issue is likely caused by a specific app or file you backed up. Try restoring only your accounts and settings instead of your full backup, then read apps one at a time to find which one is causing the problem.
Do I need a Samsung account to reset my tablet?
You do not need a Samsung account to reset the tablet itself. However, if you want to back up your data before resetting, a Samsung account makes it easier. You can also back up to Google Drive or Google Photos without a Samsung account — just sign in with your Google account.
How long does a factory reset actually take?
The reset process itself takes 10 to 30 minutes depending on how much data is on your tablet. The initial setup after the reset (signing in to accounts, downloading apps) can take another 30 minutes to an hour. Plan for the whole process to take at least an hour from start to finish.
