What a factory reset does and when you need one

A factory reset erases everything on your Android tablet — all apps you installed, photos, documents, accounts, and settings — and returns it to the state it left the factory. The tablet itself stays the same; you are not changing the hardware or the version of Android it runs.

You might reset your tablet if it is running slowly, crashing repeatedly, or behaving strangely after installing an app. You might also reset it before selling or giving it away, or if you forgot your PIN or password and cannot unlock it. A reset is a last resort when troubleshooting has not worked, because you lose everything that is not backed up.

Before you start, back up anything you want to keep. Photos, documents, and contacts can be backed up to Google Drive, OneDrive, or your email. If you are locked out and cannot access those services, a reset is sometimes the only way forward — but you will lose the data on the tablet.

Key Takeaways

  • A factory reset erases all apps, photos, documents, and settings, so back up anything you need before you start.
  • You can reset through Settings on most tablets, or through recovery mode if the tablet will not turn on or respond.
  • The reset process takes 5 to 15 minutes and the tablet will restart several times during it.
  • After the reset, you will need to sign in with a Google account to set up the tablet again.
  • If you are locked out of the tablet, you may need to use recovery mode or contact the manufacturer for help.

Reset through Settings if the tablet turns on and responds

This is the simplest path if your tablet is working well enough to navigate. Open Settings, then look for System or About tablet — the exact name varies by manufacturer and Android version. Scroll down and tap Reset options or Reset.

You will see Erase all data or Factory reset. Tap it. The tablet will ask you to confirm and may ask for your PIN, password, or Google account password. Enter it, then tap Erase or Reset. The tablet will restart and begin erasing. This takes 5 to 15 minutes. Do not turn it off or unplug it during this time.

When the reset finishes, the tablet will restart and show a setup screen. You will need to sign in with a Google account to continue. If you do not have one, you can create one during setup. After you sign in, the tablet is ready to use, and you can reinstall your apps from the Play Store.

Reset through recovery mode if the tablet will not start or respond

If your tablet is frozen, will not turn on, or will not respond to touch, you can reset it through recovery mode. This is a special menu that runs before Android loads. The button combination varies by manufacturer, but the most common is: hold Power and Volume Up together for 10 to 15 seconds until you see a logo or menu.

Once you are in recovery mode, you will see a menu with options like Reboot system now, Wipe data/factory reset, and Wipe cache partition. Use the volume buttons to move up and down, and the power button to select. Highlight Wipe data/factory reset and press power to select it.

The tablet will ask you to confirm. Select Yes using the volume and power buttons. The reset will begin. When it finishes, you will see Reboot system now highlighted. Press power to restart. The tablet will boot into the setup screen, and you will sign in with a Google account as described above.

If the button combination does not work, check the manufacturer's support page for your specific model — Samsung, Amazon, Apple, and others have different combinations. If you cannot reach recovery mode, contact the manufacturer's support line.

What to do if you are locked out and cannot reset through Settings

If you forgot your PIN, pattern, or password and the tablet will not let you into Settings, recovery mode is your next option. Follow the steps above to enter recovery mode and select Wipe data/factory reset. This will erase the lock screen along with everything else.

If recovery mode does not work or you cannot reach it, you may need to contact the tablet manufacturer's support line. Some manufacturers can help you unlock the tablet remotely or provide a master reset code. Have your proof of purchase or serial number ready — they may ask for it.

If the tablet is very old or the manufacturer no longer supports it, a repair shop may be able to help, though they will likely charge a fee. This is a last resort when all other options are exhausted.

Backing up before you reset

If your tablet is still working, take 10 minutes to back up before you reset. Open Settings, then Google or Accounts. Tap your Google account and look for Backup or Sync. Make sure Backup is turned on. This backs up your contacts, calendar, and some app data to Google Drive.

For photos and videos, open the Google Photos app, tap your profile picture, and make sure Backup and sync is on. This uploads your photos to Google Drive. For documents, use Google Drive, OneDrive, or Dropbox to upload files you want to keep.

After the reset, sign in with the same Google account, and your contacts, calendar, and backed-up photos will return. Apps will not return automatically — you will need to reinstall them from the Play Store, but your app data (like game progress or saved settings) may restore if the app developer backed it up.

What happens after the reset is complete

When the tablet restarts after the reset, it will show a welcome screen in the language you set during the initial setup. You will be asked to sign in with a Google account. Use the same account you used before if you want your backed-up contacts and photos to return.

After you sign in, the tablet will read and install updates, which may take 10 to 30 minutes depending on your internet connection. Let it finish before you start using the tablet. Once updates are done, you can open the Play Store and reinstall your apps.

The tablet will feel like a new device — it will be faster if slowness was the problem, and it will have no trace of the old setup. If the problem you were trying to fix returns, the issue may be with a specific app or a hardware problem, and you may need to contact support.

Frequently Asked Questions

Will a factory reset remove the version of Android on my tablet?

No. A factory reset only erases your data and settings. The version of Android stays the same. If you want to update Android, you do that through Settings after the reset is complete.

Can I stop the reset once it starts?

Not safely. If you turn off the tablet during a reset, it may not start again or may get stuck. Let it finish, even if it takes longer than expected. Do not unplug it or remove the battery.

What if I do not have a Google account?

You can create one during setup for free at google.com. You need a Google account to use the Play Store and to back up your data. If you do not want to create one, you can skip it during setup, but you will not be able to install apps.

Will my apps come back after I sign in with my Google account?

Not automatically. You will need to open the Play Store and reinstall them. However, if the app developer backed up your data, your settings and progress may restore when you reinstall the app.

How long does a factory reset take?

Usually 5 to 15 minutes, depending on how much data is on the tablet and how fast it is. The tablet will restart several times. Do not turn it off during this time.
