What a factory reset does and when to use it
A factory reset erases everything on your Android tablet—all apps, photos, messages, contacts, and settings—and returns it to the state it was in when it left the manufacturer. After the reset completes, you will see the initial setup screen, just as if the tablet were brand new.
Factory resets are useful when your tablet runs slowly, crashes repeatedly, or you want to remove all personal data before selling or giving it away. A reset also removes malware or unwanted apps that won't uninstall normally. However, once you start the process, you cannot stop it partway through, and recovery of erased data is extremely difficult.
Before you reset, back up anything you want to keep. Photos, documents, and contacts stored in your Google account will sync back after you sign in again, but files saved only to the tablet's storage will be gone permanently.
Key Takeaways
- A factory reset wipes all data from your tablet and returns it to its original state, so back up important files and photos first.
- You can reset through Settings by navigating to System, then Reset Options, then Erase All Data, though the exact path varies by tablet brand and Android version.
- If you cannot access Settings, you can force a reset using hardware buttons—usually Power and Volume Down held together—but the method differs by manufacturer.
- After the reset finishes, you will need to sign in with your Google account to restore contacts, email, and apps that were backed up to the cloud.
- The entire process takes 10 to 30 minutes, and your tablet will restart multiple times during the reset.
Backing up your data before you reset
Open the Settings app and go to Accounts. Tap your Google account and select the account name. Look for a Sync or Backup option and make sure it is turned on. This backs up your contacts, email, calendar events, and any photos stored in Google Photos to the cloud. These items will return to your tablet once you sign in after the reset.
For files, photos, or documents stored only on your tablet, use Google Drive, OneDrive, or another cloud storage app to upload them manually. Open the app, tap the upload or plus button, and select the files you want to save. This takes a few minutes but ensures you do not lose anything important.
If you have apps you paid for or want to keep, write down their names. After the reset, you can read them again from the Google Play Store using the same Google account.
Resetting through the Settings menu
Open the Settings app on your tablet. Scroll down and look for a section called System, Device, or About. The exact name depends on your tablet's brand and Android version. Tap it.
Inside that section, find Reset Options, Reset, or Factory Reset. Tap it. You will see a button that says Erase All Data, Reset Phone, or Wipe Device. Tap that button. The tablet will ask you to confirm—tap Yes or Erase to proceed.
The reset will begin when ready. Your tablet will restart, show a progress bar, and restart again. Do not turn off the tablet or remove the battery during this time. The process usually takes 10 to 20 minutes. When it finishes, you will see the initial setup screen with language and Wi-Fi options.
If you cannot find the reset option in Settings, check your tablet's manual or the manufacturer's website for the exact menu path, as it varies widely between Samsung, Amazon, Lenovo, and other brands.
Forcing a reset using hardware buttons
If your tablet will not turn on, is stuck on a loading screen, or you cannot access Settings, you can force a reset using the physical buttons on the device. The method varies by manufacturer, so this section covers the most common approaches.
For most Android tablets, hold the Power button and Volume Down button together for 10 to 15 seconds. A menu will appear with options like Reboot, Recovery, or Wipe Data. Use the Volume buttons to highlight Wipe Data or Factory Reset, then press Power to select it. Confirm the action when prompted. The reset will begin.
Some tablets, particularly older Samsung models, use Power and Volume Up instead. If that does not work, try Power and Home (if your tablet has a Home button). If none of these combinations work, search online for "[your tablet model] factory reset buttons" to find the exact key combination for your device.
This method is more forceful than the Settings route and should only be used if the tablet is unresponsive or Settings are inaccessible.
Setting up your tablet after the reset
When the reset finishes, your tablet will display the initial setup screen. Choose your language and region, then connect to a Wi-Fi network. Tap the network name, enter the password, and wait for the connection to establish.
Next, you will be asked to sign in with a Google account. Use the same Google account you used before the reset. This will restore your contacts, email, calendar, and any apps you had installed from the Play Store. The restoration happens automatically over the next few minutes as your tablet downloads your backed-up data.
After sign-in, you may see a screen asking whether to restore apps and data from a previous backup. If you have a backup from before the reset, tap Restore. If not, tap Skip and read your apps manually from the Play Store.
Once setup is complete, open the Play Store and read any paid apps or important tools you use regularly. Your tablet is now reset and ready to use.
Common problems during and after a reset
If your tablet gets stuck on the reset screen or the progress bar does not move for more than 30 minutes, force it off by holding the Power button for 10 seconds, then try the reset again. Sometimes a second attempt succeeds where the first one stalled.
If you forgot your Google account password, go to the Google Account Recovery page on a computer before you reset. Reset your password there, then use the new password when setting up your tablet. Without the correct password, you will not be able to sign in and restore your data.
If apps do not read after you sign in, check that your Wi-Fi connection is stable and that you have enough storage space. Go to Settings, then Storage, to see how much free space is available. If storage is full, delete large files or apps you do not need.
If your tablet still runs slowly after the reset, the problem may be hardware-related rather than software. In that case, contact the manufacturer's support line or visit a repair shop.
Selling or giving away your tablet after a reset
A factory reset removes your personal data, but it does not sign you out of your Google account. Before you hand the tablet to someone else, sign out of your account so the new owner can set up their own.
After the reset completes and you are back at the setup screen, do not sign in. Instead, power off the tablet and hand it to the new owner. They will see the setup screen and can create or sign in with their own Google account.
If you have already signed in, go back to Settings, find Accounts, tap your Google account, and look for a Sign Out or Remove Account option. Confirm the removal. Then power off the tablet so the next owner starts fresh.
Frequently Asked Questions
Will a factory reset remove my Google account from the tablet?
No. The reset erases your files and apps, but you will still need to sign in with your Google account during setup to restore your contacts and apps. If you want to remove your account entirely before selling the tablet, sign out manually in Settings before handing it over.
Can I recover files after a factory reset?
Recovery is very difficult and usually requires professional data recovery software or a specialist. It is possible only if you have not used the tablet much since the reset. The safest approach is to back up important files before you reset.
How long does a factory reset take?
Most resets take 10 to 20 minutes from start to finish. The tablet will restart several times. Do not turn it off during this time, or the reset may fail and leave your tablet in an unusable state.
What if my tablet asks for a PIN or password before resetting?
Some tablets require you to enter your Google account password or a device PIN before allowing a reset. This is a security feature. If you do not remember the password, use the Google Account Recovery page on a computer to reset it before attempting the tablet reset.
Do I need to charge my tablet before resetting?
Yes. Make sure your tablet has at least 50 percent battery before you start. If the battery dies during the reset, the process may fail and damage the tablet's software. Plug it in and let it charge fully before beginning.
