What Happens When You Factory Reset Your Android Tablet
A factory reset erases everything on your tablet and returns it to the state it was in when it left the factory. This means all your apps, photos, videos, documents, messages, and settings disappear. Your tablet will restart with only the pre-installed apps that came with it, and you will need to sign back into your Google account to read your apps again.
Factory resets are useful when your tablet is running slowly, freezing often, or behaving strangely. They also work if you are selling or giving away your tablet and want to make sure no personal information remains on it. Before you start, understand that this process cannot be undone — once the reset completes, the data is gone.
Key Takeaways
- Back up any photos, documents, or files you want to keep before starting, because a factory reset deletes everything on your tablet.
- You can factory reset through Settings by going to System, then Reset Options, then Erase All Data — the exact path varies slightly by manufacturer and Android version.
- You will need your Google account password after the reset, because Android requires you to sign in before the tablet fully boots up.
- The reset process takes 5 to 15 minutes depending on how much data is on your tablet, and your tablet will restart several times during this time.
- If your tablet is frozen or won't turn on, you can force a factory reset using hardware buttons, though this method varies by tablet model.
Back Up Your Files Before You Reset
Before you erase your tablet, save anything you need. Photos and videos can be backed up to Google Photos, which stores them in your Google account. Open Google Photos, tap your profile picture in the top right, go to Photos Settings, and turn on Backup and Sync. Your photos will upload automatically over Wi-Fi.
Documents, spreadsheets, and other files can be saved to Google Drive. Open the Files app on your tablet, select the files you want to keep, tap the three dots, and choose "Save to Drive." You can also email important documents to yourself or copy them to a computer using a USB cable.
If you have notes, contacts, or calendar events, these are usually saved to your Google account automatically if you set up your tablet with a Google account. You can check by opening Settings, tapping Accounts, selecting your Google account, and looking for what is synced. Anything checked is already backed up.
Factory Reset Through Settings (Standard Method)
This is the easiest way to reset your tablet if it is working normally. Open Settings and look for a System option — on some tablets it may be called "About Tablet" or just appear at the bottom of the Settings list. Tap System, then look for Reset Options or Reset.
You will see an option that says "Erase All Data" or "Factory Reset." Tap it. Your tablet will ask you to confirm and may ask for your PIN, pattern, or password to make sure you really want to do this. Enter it if prompted. The tablet will then begin erasing data, which takes 5 to 15 minutes. Do not turn off your tablet during this time.
When the reset finishes, your tablet will restart and show a welcome screen, just like when it was brand new. You will be asked to set up your language, connect to Wi-Fi, and sign into your Google account. Use the same Google account you used before — this lets you read your apps again and access your backed-up photos and files.
Factory Reset Using Hardware Buttons (If Your Tablet Won't Start)
If your tablet is frozen, won't turn on, or won't respond to touch, you can force a factory reset using the power and volume buttons. The exact button combination depends on your tablet model, but the most common method is to hold the Power button and Volume Down button together for 10 to 15 seconds until you see a recovery menu appear on the screen.
Once the recovery menu appears, use the volume buttons to move up and down through the options and the power button to select. Look for an option that says "Wipe Data" or "Factory Reset." Select it, then confirm when asked. The tablet will erase everything and restart. This process takes longer than the Settings method — sometimes 20 to 30 minutes — because the tablet is working harder to recover.
If you are not sure what buttons to press for your specific tablet model, search online for "[Your Tablet Model] factory reset buttons" or check the manufacturer's support website. Pressing the wrong buttons will not harm your tablet, but it may not start the reset process.
What to Do After the Reset Completes
When your tablet restarts, you will see the initial setup screen. Choose your language and region, then connect to Wi-Fi. You will be asked to sign into a Google account — use the same one you used before the reset. This is important because it lets you restore your apps, contacts, and backed-up files.
After you sign in, your tablet will read and reinstall your apps automatically. This can take 30 minutes to an hour depending on how many apps you had and how fast your Wi-Fi is. Let it finish without interrupting. Once the apps are installed, your photos and files from Google Photos and Google Drive will be available again.
If you do not remember your Google account password, go to the Google Account Recovery page on a computer before you reset your tablet. You can reset your password there, and then use the new password when setting up your tablet.
Common Problems and How to Fix Them
If your tablet gets stuck on the setup screen after a reset, try turning it off completely by holding the power button for 30 seconds, then turning it back on. If it still does not move forward, try connecting to a different Wi-Fi network or using a mobile hotspot from your phone.
If you forgot your Google account password and cannot sign in, you will need to recover your account from a computer. Go to accounts.google.com, click "Find My Account," and follow the steps to reset your password. Once you have a new password, use it to sign into your tablet.
If your tablet is very slow after the reset, wait a few hours for it to finish installing apps and indexing files in the background. If it is still slow after a full day, try restarting it once more. A tablet that has just been reset sometimes needs time to settle.
When to Factory Reset vs. When to Try Other Fixes
A factory reset solves most problems caused by software — apps crashing, the tablet freezing, or the system running slowly. However, if your tablet has a hardware problem like a cracked screen, a battery that does not hold a charge, or buttons that do not work, a factory reset will not fix it.
Before you reset, try restarting your tablet first. Hold the power button until "Power Off" appears, tap it, wait 10 seconds, then turn it back on. Many problems go away after a restart. If restarting does not help and you do not need the data on your tablet, then a factory reset is worth trying.
If your tablet is still under warranty and you suspect a hardware problem, contact the manufacturer's support before resetting. A factory reset may void your ability to return the tablet for repair, depending on the warranty terms.
Frequently Asked Questions
Will I lose my Google account after a factory reset?
No. Your Google account is stored on Google's servers, not on your tablet. After the reset, you sign back in with the same email and password, and your account is restored. Your apps, contacts, and backed-up files will be available again.
Can I undo a factory reset?
No. Once a factory reset completes, the data is permanently erased and cannot be recovered. This is why backing up before you reset is so important. If you have backed up your files to Google Drive or Google Photos, you can restore them after signing back in.
Do I need to charge my tablet before I reset it?
Yes. Make sure your tablet has at least 50 percent battery before you start. If the battery dies during the reset, your tablet may not restart properly. Plug it in and let it charge fully before beginning.
How long does a factory reset take?
The reset itself takes 5 to 15 minutes. After that, your tablet restarts and asks you to set up your account, which takes another 5 to 10 minutes. Downloading and installing your apps can take 30 minutes to an hour depending on how many apps you had and your Wi-Fi speed.
What if I do not remember which Google account I used on my tablet?
Before you reset, open Settings and tap Accounts to see which Google account is signed in. Write down the email address. If you reset without checking and cannot remember, you can try common email addresses you use. If none work, you will need to create a new Google account and set up your tablet as if it were brand new.
