What Formatting a Samsung Tablet Means

Formatting a Samsung tablet erases all data on the device and returns it to factory settings. This wipes your apps, photos, files, contacts, and any personal information stored on the tablet. The process takes 10 to 30 minutes depending on how much data is on the device.

You might format a tablet to fix software problems, prepare it for sale or donation, or start fresh after a security concern. Before you begin, back up anything you want to keep—photos, documents, contacts—because formatting cannot be undone.

Key Takeaways

  • Formatting erases everything on your tablet and returns it to the state it was in when you first bought it.
  • You can format through Settings on the tablet itself, or through Find Mobile (Samsung's remote service) if you cannot access the device.
  • Back up your photos, files, and contacts to a cloud service or computer before you start, because the process cannot be reversed.
  • After formatting, the tablet will ask you to sign in with a Samsung account or Google account to set it up again.
  • If you forget your Samsung or Google password, you will not be able to use the tablet after formatting, so write down your credentials first.

Back Up Your Data Before You Start

The first step is to save anything you want to keep. Open Settings and tap Accounts and backup. Choose Samsung Cloud or Google One (whichever you use) and tap Back up. This saves your contacts, calendar events, and some app data to the cloud.

For photos and videos, open Gallery, select the files you want to keep, and tap the three-dot menu. Choose Move to cloud or Share to send them to Google Photos, OneDrive, or another cloud service. You can also connect your tablet to a computer with a USB cable and drag files to a folder on your computer.

Write down your Samsung account password and Google account password before you format. After formatting, you will need to sign in with one of these accounts to use the tablet again. If you forget the password, you will be locked out.

Format Through Settings on Your Tablet

This is the standard method if your tablet turns on and you can access the home screen. Open Settings and scroll down to General management. Tap Reset.

You will see two options: Reset network settings and Factory data reset. Tap Factory data reset. The tablet will show a warning that all data will be erased. Read it, then tap Reset or Delete all (the button name varies by model).

The tablet will ask you to confirm by typing your PIN, pattern, or password if you have one set. Enter it and tap Continue. The formatting process will begin. Do not turn off the tablet or remove the battery during this time. The screen will show a progress bar or spinning icon. When it finishes, the tablet will restart and show the initial setup screen, as if it were brand new.

Format a Tablet You Cannot Access

If your tablet will not turn on, is frozen, or you cannot remember your PIN, use Find Mobile, Samsung's remote service. Go to findmobile.samsung.com on a computer and sign in with the Samsung account that is linked to the tablet.

Click Find My Mobile and select your tablet from the list of devices. Click More and choose Factory reset. Confirm the action. Samsung will send a command to the tablet to erase it remotely. This can take a few minutes to work, and the tablet must be connected to the internet (Wi-Fi or mobile data) for the command to go through.

If the tablet is offline, the reset will happen the next time it connects to the internet. You will need the Samsung account password to complete this step.

What Happens After Formatting

When the tablet restarts after formatting, it will show the Welcome or Setup screen. You will be asked to choose a language and connect to Wi-Fi. Then you will see a screen asking you to sign in with a Google account or Samsung account.

Use the same account you used before formatting, or a different one if you prefer. If you use the same account, the tablet will automatically read apps you had installed before, restore your contacts, and set up your email. This can take 10 to 20 minutes depending on how many apps you had.

If you do not have a Google or Samsung account, you can create one during setup. You will need a valid email address. After setup is complete, your tablet will work normally, and you can start installing apps and adding files again.

Common Problems After Formatting

Locked out after formatting: If you cannot remember the Google or Samsung account password, you will not be able to use the tablet. This is a security feature to prevent theft. You will need to reset the password on a computer by going to accounts.google.com or account.samsung.com, then sign in on the tablet with the new password.

Apps not reinstalling: After signing in, the tablet should automatically read apps you had before. If it does not, open the Google Play Store or Galaxy Store and go to My apps and games. Tap Library and you will see a list of apps you have installed on other devices. Tap the read icon next to each one you want to reinstall.

Tablet stuck on setup screen: Make sure you have a strong Wi-Fi connection. If the tablet is still stuck after 10 minutes, restart it by holding the power button for 10 seconds until it turns off, then turn it back on. If it stays stuck, try formatting again from Settings.

When to Format vs. When to Restart

Formatting is a drastic step and should not be your first choice for fixing problems. If your tablet is slow, freezing, or has a minor software glitch, try restarting it first. Hold the power button until the power menu appears, then tap Restart. This takes 2 to 3 minutes and fixes most temporary issues without erasing anything.

If restarting does not work, try clearing the cache. Go to Settings, tap Apps, select an app that is causing problems, and tap Storage. Choose Clear cache. This removes temporary files the app created without deleting your data.

Format only if the tablet has a serious problem that restarting and clearing cache do not fix, or if you are preparing it for someone else to use.

Frequently Asked Questions

Will formatting remove my Samsung account?

Formatting removes all data from the tablet, but it does not delete your Samsung account. After formatting, you will sign in with the same account again during setup. Your account information stays on Samsung's servers.

Can I format a Samsung tablet without a password?

If you do not have a PIN, pattern, or password set, you can format without entering one. If you do have one set and cannot remember it, use Find Mobile on a computer to format remotely. You will need the Samsung account password for that method.

How long does formatting take?

The actual formatting process takes 5 to 15 minutes. After that, the tablet will restart and show the setup screen, which takes another 5 to 10 minutes to complete. The total time is usually 15 to 30 minutes depending on how much data was on the tablet.

Will formatting fix a virus or malware?

Yes, formatting removes all software on the tablet, including any malware. After formatting and signing in again, only the apps you choose to reinstall will be on the device. This is one of the most reliable ways to clean a tablet that has been compromised.

Can I stop the formatting process once it starts?

No, you should not interrupt formatting once it begins. If you turn off the tablet or remove the battery during formatting, it may become unusable. Let the process finish completely, even if it takes longer than expected. If the tablet appears frozen, wait at least 30 minutes before assuming something went wrong.
