What a factory reset does and when you need one

A factory reset erases everything on your Samsung Galaxy Tablet A and returns it to the state it left the factory. This means all your photos, videos, apps, messages, and settings disappear. The operating system stays the same — you do not downgrade or upgrade Android — but every personal file and configuration goes.

You might factory reset because the tablet is running slowly, an app keeps crashing, you are selling or giving it away, or you forgot your PIN or password. If you are troubleshooting a problem, try restarting the tablet first; many issues clear without a full reset. If you are preparing to hand it to someone else, a factory reset is the right step to protect your privacy.

Before you start, back up anything you want to keep. Photos and documents stored in Google Drive, OneDrive, or Samsung Cloud will still be there after the reset. Files saved only to the tablet's internal storage will not be.

Key Takeaways

  • A factory reset removes all personal files, apps, and settings but keeps the Android operating system version intact.
  • You can factory reset through Settings, or by holding Power and Volume Up together if the tablet will not turn on normally.
  • The process takes 5 to 15 minutes and the tablet will restart several times during the reset.
  • After the reset, you will need to sign in with a Google account to set up the tablet again.
  • Back up photos, documents, and other files to Google Drive or Samsung Cloud before you start, because they will be deleted.

Factory reset through Settings (the standard method)

Open Settings on your tablet. Scroll down and tap General management (on some models this is called System). Look for Reset or Reset options and tap it.

You will see several reset choices. 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 change your mind. Tap Reset or Delete all to proceed.

If the tablet asks for your Samsung account password or Google password, enter it. This is a security step to prevent someone else from wiping your device remotely. The reset will then begin. Your tablet may restart several times and show a progress bar. Do not turn it off during this time. The whole process usually takes 5 to 15 minutes.

When the reset is complete, the tablet will restart and show the initial setup screen, the same one you saw when you first turned it on. You will need to sign in with a Google account to continue.

Factory reset using hardware buttons (if the tablet will not start)

If your tablet is frozen, will not turn on, or will not let you access Settings, you can force a factory reset using the physical buttons. Power off the tablet completely. If it is stuck, hold the Power button for 10 seconds until it shuts down.

Once it is off, hold down the Power button and Volume Up button together for several seconds. Keep holding them until the Samsung logo appears or you see a menu with text. Release the buttons.

You should now see a screen with options in white text on a black background. This is called recovery mode. Use the Volume Down button to scroll to Wipe data/factory reset and press the Power button to select it. The tablet will ask you to confirm. Scroll to Yes using Volume Down and press Power to confirm.

The reset will begin. This method takes longer than the Settings method — sometimes 20 to 30 minutes — and the tablet will restart multiple times. Let it finish without interruption. When it is done, you will see the setup screen again.

What to do if you are locked out of your Google or Samsung account

After a factory reset, your Samsung Galaxy Tablet A will ask you to sign in with a Google account. If you do not remember your Google password, go to accounts.google.com on a computer or another device and click Forgot password? Follow the steps to recover your account. You will usually need access to a recovery email or phone number you set up with Google.

If you do not have access to any recovery method and cannot sign in, you may not be able to use the tablet. Google's security system is designed to prevent someone else from accessing your account, even if they have your device. Contact Google Support through their website to explain your situation; they can sometimes help you regain access.

For Samsung accounts, the process is similar. Go to samsung.com, find the sign-in page, and look for Forgot password? or Find your ID. You will need to verify your identity using a recovery email or phone number.

Backing up your files before the reset

The easiest way to back up is through Google. Open Settings, tap Accounts, then Google. Select your Google account and tap Account sync. Turn on the toggle for Photos, Drive, Contacts, and any other data you want to save. Your tablet will sync these to your Google account automatically.

For Samsung devices, you can also use Samsung Cloud. Open Settings, tap Accounts, then Samsung Cloud. Sign in with your Samsung account and tap Backup. Select what you want to save — photos, contacts, settings, and app data are common choices — and tap Back up now.

If you have files in the tablet's file manager that are not in Google Drive or Samsung Cloud, connect the tablet to a computer with a USB cable and copy them to a folder on your computer. This is the only way to save files that live only on the tablet's internal storage.

Setting up your tablet after the factory reset

When your tablet restarts after the reset, you will see the initial setup screen. Choose your language and region, then connect to a Wi-Fi network. The tablet will ask you to sign in with a Google account. Use the same account you used before, or a different one if you prefer.

After you sign in, the tablet will ask whether you want to restore from a backup. If you backed up to Google or Samsung Cloud, select Restore and choose which backup to use. Your photos, contacts, and app data will read back to the tablet. This can take several minutes depending on how much data you have.

You will then be asked to set up additional features like fingerprint or face recognition if your model supports them. You can skip these and set them up later in Settings if you prefer. Once setup is complete, your tablet is ready to use.

Frequently Asked Questions

Will a factory reset remove the Android operating system?

No. A factory reset only removes your personal files, apps, and settings. The version of Android that came with your tablet stays the same. If you want to update Android to a newer version, you can do that after the reset through Settings > About tablet > Software update.

How long does a factory reset take?

Through Settings, most resets finish in 5 to 15 minutes. Using the hardware button method (recovery mode) usually takes 20 to 30 minutes because the tablet restarts more times. Do not turn off the tablet during the reset, even if it seems stuck — let it finish.

Can I stop a factory reset once it starts?

If you are using the Settings method and have not yet confirmed, you can go back. Once you tap the final confirmation button, the reset begins and cannot be stopped. If you are using the hardware button method, the reset cannot be interrupted. Let it complete.

What happens to apps I installed from the Google Play Store?

They are deleted during the reset. After you sign back in with your Google account, you can reinstall them from the Play Store. Apps you purchased will still show as purchased under your account, so you will not have to pay again.

Do I need to remove my SD card before a factory reset?

No, but files on an SD card are not affected by a factory reset anyway. The reset only clears the tablet's internal storage. If you want to keep files on the SD card separate, you can leave it in. If you want to wipe the SD card too, remove it first, then reset the tablet, then format the card separately.
