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 a reset, the tablet will ask you to set up as if it were brand new.
You need a factory reset if the tablet is running slowly, freezing repeatedly, or behaving erratically after months of use. A reset also clears out malware or unwanted software that uninstalling alone won't remove. If you are selling or giving away the tablet, a reset ensures the next owner cannot access your personal data.
A reset is not the same as a restart. Restarting just turns the tablet off and back on. A reset wipes the storage. Once you start a factory reset, you cannot stop it partway through, so back up anything you want to keep first.
Key Takeaways
- Back up your photos, documents, and any files you want to keep before starting a reset, because the process erases everything on the tablet.
- The fastest method is Settings > General Management > Reset > Factory Data Reset, which takes five to ten minutes.
- If the tablet is frozen and you cannot open Settings, hold the power button and volume down button together for ten seconds to force a restart, then try the Settings method again.
- After the reset completes, the tablet will ask you to sign in with a Samsung account or Google account, just as it did when new.
How to reset through Settings on a working tablet
If your tablet is responsive and you can open the Settings app, this is the standard path. Open Settings by swiping down from the top of the screen, tapping the gear icon, or finding Settings in your app drawer.
Once Settings is open, scroll down and tap General Management. Look for the option labeled Reset or Reset Options — the exact wording varies by Samsung model and Android version. Tap it, then select Factory Data Reset or Erase All Data.
The tablet will show a warning that all data will be erased and ask you to confirm. Read the warning carefully. If you have a PIN, pattern, or password set on the tablet, you will need to enter it to proceed. Tap the button to confirm the reset. The tablet will restart and begin the process, which usually takes five to ten minutes. Do not turn off the tablet or remove the battery during this time.
What to do if the tablet is frozen or unresponsive
If the tablet is frozen, stuck on a loading screen, or will not open Settings, you can force a restart first. Press and hold the power button and the volume down button at the same time for about ten seconds. The tablet will vibrate and the screen will go black. Release both buttons.
Wait a few seconds, then press the power button alone to turn the tablet back on. Once it restarts, try opening Settings again and follow the standard reset steps above. If the tablet still will not respond after a forced restart, you can perform a reset using the recovery menu instead.
Resetting from the recovery menu
If the tablet is too frozen to use Settings, you can access the recovery menu directly. Turn off the tablet completely. Then press and hold the power button and volume up button together until the Samsung logo appears on the screen — this usually takes ten to fifteen seconds. Keep holding until you see the recovery menu, which shows white text on a black background.
Use the volume buttons to navigate the menu and the power button to select. Look for an option that says Wipe Data, Factory Reset, or Erase All Data. Highlight it and press the power button to select it. The menu will ask you to confirm. Select Yes to proceed. The reset will begin and may take several minutes. When it finishes, the menu will show a Reboot System Now option. Select it to restart the tablet.
Backing up your files before a reset
Before you reset, move anything you want to keep to cloud storage or an external device. Photos and videos can be backed up to Google Photos, Samsung Cloud, OneDrive, or Dropbox — all of these have free tiers. Open the app, sign in with your account, and let it upload your files. Once the upload is complete, the files will still be there after the reset.
Documents, spreadsheets, and other files can go to Google Drive, OneDrive, or Dropbox the same way. If you have files stored only on the tablet's internal storage, connect the tablet to a computer with a USB cable, open the file manager on the computer, and copy the files to a folder on the computer.
Contacts and calendar events are usually tied to your Google account or Samsung account, so they will come back when you sign in again after the reset. To be certain, open Contacts, tap the menu, and look for an option to export or back up. The same applies to calendar — open the calendar app and check the menu for backup options.
Setting up the tablet after a reset
When the reset finishes and the tablet restarts, it will show a setup screen similar to the one you saw when you first bought it. You will be asked to choose a language, connect to Wi-Fi, and sign in with a Google account or Samsung account. Use the same account you used before if you want your apps, contacts, and settings to return.
If you sign in with Google, the tablet will offer to restore apps from your Google Play account. Select the apps you want and let them read. If you backed up files to Google Drive, Google Photos, or another cloud service, open that app after setup and sign in to read your files back to the tablet.
The tablet will be noticeably faster after a reset because it no longer has months of cached data, temporary files, and background processes slowing it down. This speed boost usually lasts several months before the tablet gradually accumulates clutter again.
Frequently Asked Questions
Will a factory reset remove my Google account?
The reset erases the account from the tablet, but the account itself still exists. When you set up the tablet after the reset, you can sign in with the same Google account and the tablet will restore your apps and settings from that account's backup.
Can I undo a factory reset?
No. Once a factory reset completes, the data is gone. This is why backing up before you reset is important. If you backed up to cloud storage, you can restore from there after the reset finishes.
How long does a factory reset take?
Most resets take five to fifteen minutes from start to finish. Older tablets or those with very full storage may take longer. Do not interrupt the process by turning off the tablet or removing the battery.
What if the tablet asks for a Google account after the reset?
This is a security feature called Factory Reset Protection. Sign in with the Google account that was on the tablet before the reset. If you do not remember the account or no longer have access to it, you will need to contact Samsung support with proof of ownership.
Should I reset my tablet if it is running slowly?
A reset often helps if the tablet has been slow for months, but try these steps first: restart the tablet, uninstall apps you do not use, clear the cache in Settings > Apps, and delete old files and photos. If the tablet is still slow after these steps, a reset is worth trying.
