What a Factory Reset Does and When to Use It

A factory reset erases everything on your Galaxy tablet—all apps, photos, messages, settings, and accounts—and returns it to the state it was in when it left the factory. After the reset completes, you will see the initial setup screen, as if you had just unboxed the device.

Factory reset your Galaxy tablet when you plan to sell or give it away, when the device is running slowly and you want a clean start, or when you cannot fix a persistent software problem any other way. Do not factory reset if you have not backed up photos, documents, or other files you want to keep—they will be permanently deleted.

Before you begin, charge your tablet to at least 50 percent battery. A factory reset can take 10 to 30 minutes, and if the battery dies during the process, the tablet may not restart properly.

Key Takeaways

  • A factory reset deletes all data on your tablet and returns it to factory settings, so back up anything you want to keep before you start.
  • You can factory reset through Settings on the tablet itself, or through Find Mobile (Samsung's remote service) if the tablet is locked or will not turn on.
  • The reset process takes 10 to 30 minutes and requires the tablet to stay powered on and connected to Wi-Fi or a mobile network.
  • After the reset, your tablet will display the initial setup screen and you can sign in with a Samsung or Google account to restore some apps and settings.

Back Up Your Data Before You Reset

The easiest way to back up a Galaxy tablet is through your Samsung account or Google account. Open Settings, tap Accounts, and select the account you use (Samsung Account or Google). Tap Sync or Backup and make sure photos, contacts, calendar, and app data are set to back up automatically. If they are already syncing, your data is already saved to the cloud.

For photos and videos you want to keep locally, connect your tablet to a computer with a USB cable, open the file manager on your computer, and copy the DCIM or Pictures folder from the tablet to your computer. You can also use Google Photos or Samsung Cloud to back up photos separately—both services let you restore them later by signing in with the same account.

If you have documents, spreadsheets, or other files in apps like Google Drive, Microsoft OneDrive, or Samsung Notes, those are usually already backed up to the cloud if you are signed in. Check each app's settings to confirm backup is turned on.

Factory Reset Through Settings

This is the standard method if your tablet turns on and you can access the home screen. Open Settings and scroll down to find General Management (on some models it may be labeled System or About Device). Tap Reset or Reset Options.

Select Factory Data Reset or Erase All Data. The tablet will show 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 Samsung account password or Google account password—this is a security step to prevent someone else from erasing your tablet remotely. Enter the password and tap Continue.

The tablet will restart and show a progress bar. Do not turn off the tablet or unplug it during this time. When the reset is complete, you will see the initial setup screen asking you to choose a language and connect to Wi-Fi. The entire process usually takes 10 to 30 minutes depending on how much data was on the tablet.

Factory Reset Using Find Mobile (If Your Tablet Is Locked)

If your Galaxy tablet will not turn on, is frozen, or is locked with a password you do not remember, you can reset it remotely using Find Mobile, Samsung's device management service. Go to findmobile.samsung.com on a computer and sign in with the Samsung account that is registered to the tablet.

Select your tablet from the list of devices. Click More or Options and choose Unlock or Factory Reset. If you choose Factory Reset, the tablet will erase all data and restart. This can take 15 to 45 minutes depending on the tablet's condition. The tablet must be connected to the internet (Wi-Fi or mobile data) for this to work.

If you do not have a Samsung account set up on the tablet, or if you do not remember the account password, you will need to contact Samsung Support or visit a Samsung service center. Bring proof of purchase if possible.

What Happens After the Reset

When the reset is complete, your tablet will display the setup screen. Choose your language, connect to Wi-Fi, and sign in with a Google account or Samsung account. If you sign in with the same account you used before the reset, the tablet will offer to restore some apps and settings automatically—this usually takes a few minutes to an hour depending on how many apps you had.

Your tablet will not automatically restore photos, videos, or documents that were stored locally (not in the cloud). If you backed up photos to Google Photos or Samsung Cloud before the reset, open that app, sign in, and the photos will appear. If you backed up files to your computer, you can copy them back to the tablet using a USB cable.

After setup is complete, you can read apps from the Google Play Store or Samsung Galaxy Store, sign in to email accounts, and restore any settings you remember. The tablet is now in the same state as a brand-new device.

Common Mistakes to Avoid

Do not unplug the tablet or turn it off during the reset process. If the battery dies or you interrupt the reset, the tablet may get stuck on the startup screen and may not boot properly. Always charge to at least 50 percent before you start.

Do not forget your Samsung or Google account password. If the tablet asks for the password during reset and you cannot remember it, you will not be able to complete the reset. If this happens, go to the account recovery page (accounts.google.com or account.samsung.com) on a computer and reset the password before you try again.

Do not assume all your data is backed up. Check your cloud storage (Google Drive, Samsung Cloud, OneDrive) before you reset to make sure important files are there. Photos and videos stored only in the tablet's local storage will be permanently deleted.

Frequently Asked Questions

Will a factory reset remove the Google account from my tablet?

Yes. The reset erases all accounts, including Google and Samsung accounts. After the reset, you will need to sign in again with your Google or Samsung account during the setup process. If you do not remember the password, you can reset it on a computer before you set up the tablet again.

Can I factory reset a Galaxy tablet without a password?

If you can access Settings, yes—you can factory reset without entering a password. If the tablet is locked and you cannot reach Settings, you will need the Samsung account password or Google account password to reset it remotely through Find Mobile. If you do not have access to either password, contact Samsung Support.

How long does a factory reset take?

Most factory resets take 10 to 30 minutes from start to finish. If your tablet has a lot of data or is running slowly, it may take up to 45 minutes. The tablet must stay powered on and connected to Wi-Fi or mobile data during the entire process.

Will I lose my Google Play apps after a factory reset?

Your apps will be deleted from the tablet, but they are tied to your Google account. When you sign in with the same Google account after the reset, you can reinstall them from the Google Play Store. The store will show which apps you owned before, and you can read them again for free.

What if my tablet gets stuck after a factory reset?

If the tablet is stuck on the setup screen or will not respond, try holding the power button for 10 seconds to force it to shut down, then turn it back on. If it still does not respond, plug it in to charge for at least 30 minutes, then try again. If the problem continues, contact Samsung Support or visit a service center.
