What a Samsung Galaxy reset does and when to use it

A reset on your Samsung Galaxy phone clears out data, settings, and apps to return the phone to the state it was in when it left the factory. There are two main types: a soft reset, which is a straightforward restart that keeps all your data, and a factory reset, which erases everything on the phone.

A soft reset fixes freezing, slow performance, or apps that crash without losing anything. A factory reset is what you do before selling the phone, giving it away, or when the phone has serious problems that a restart won't fix. Before you do a factory reset, back up your photos, contacts, and any files you want to keep — once they're gone, they're gone.

Key Takeaways

  • A soft reset (restart) fixes most temporary problems and keeps all your data intact.
  • A factory reset erases everything on the phone, so back up your data first using Samsung Cloud, Google Drive, or a computer.
  • You can factory reset through Settings, or use the hardware button combination if the phone won't turn on or respond.
  • After a factory reset, you'll need to sign in with your Samsung account or Google account to restore your apps and settings.
  • If the phone is locked with a PIN or pattern, you'll need that code before the reset will complete.

How to do a soft reset (restart)

Press and hold the power button on the side of your phone until the power menu appears on the screen. This usually takes 3 to 5 seconds. Tap Restart or Reboot — the exact wording depends on your Galaxy model and Android version.

The phone will turn off and back on. This clears temporary data from memory and often fixes apps that are frozen or a phone that feels sluggish. Your photos, messages, contacts, and installed apps all stay exactly as they were.

How to factory reset through Settings

Open Settings and scroll down to find General management or System (the location varies by model). Tap it, then look for Reset or Reset options. You should see Factory data reset or Erase all data.

Tap that option. The phone will show you a warning that all data will be erased and ask you to confirm. If your phone is locked with a PIN, pattern, or password, you'll need to enter it now. Tap Reset or Delete all to confirm. The phone will restart and erase everything — this can take several minutes.

When it's done, you'll see the setup screen as if the phone is brand new. You can sign in with your Google account or Samsung account to restore your apps, photos, and settings from backup.

How to factory reset using hardware buttons

If your phone won't turn on, won't respond to touches, or is stuck in a loop, you can force a factory reset using the physical buttons. The button combination varies by Galaxy model, but the most common is: power button + volume up button.

Turn off the phone completely. Press and hold the power button and volume up button at the same time for about 10 seconds until the Samsung logo appears or the recovery menu shows up. Release the buttons. You should see a menu with options like Wipe data/factory reset or Factory reset.

Use the volume buttons to move up and down in the menu, and press the power button to select. Choose the factory reset option, confirm the selection, and wait for the phone to erase and restart. This process can take 5 to 15 minutes depending on how much data is on the phone.

Back up your data before a factory reset

The easiest way to back up a Samsung Galaxy is through Samsung Cloud. Open Settings, go to Accounts and backup or Samsung account, and tap Backup. Choose what you want to save — contacts, messages, app data, home screen layout, and settings are the main options. Tap Back up and wait for it to finish. You'll need a Samsung account, which is free to create.

You can also use Google Drive to back up photos, documents, and some app data. Open the Google Drive app, tap the menu button (three horizontal lines), go to Settings, and turn on Backup. Or, open Settings, go to Google, tap Manage your Google Account, go to the Data & Privacy tab, and look for backup options there.

For photos and videos, connect your phone to a computer with a USB cable and copy the files from the DCIM folder (where photos are stored) or Pictures folder to your computer. This is the safest way to make sure you don't lose anything important.

What to do after the factory reset is complete

When the phone restarts after a factory reset, you'll see the initial setup screen. Choose your language and region, then connect to Wi-Fi. The phone will ask you to sign in with a Google account or Samsung account — use the same one you used before the reset.

Once you're signed in, the phone will begin restoring your apps, contacts, photos, and settings from backup. This can take 15 minutes to an hour depending on how much data you have and how fast your internet connection is. Don't turn off the phone or disconnect from Wi-Fi during this time.

If you backed up to Samsung Cloud, go to Settings, find your Samsung account, and tap Restore to bring back your Samsung-specific data like home screen layout and system settings. If you backed up photos to your computer, you can copy them back to the phone using a USB cable once the restore is finished.

When to call Samsung support instead

If your phone won't turn on at all, won't respond to button presses, or keeps restarting in a loop even after you try a soft reset, contact Samsung support. You can reach them through the Samsung Members app (if it will open), the Samsung website, or by calling the support number for your country. They can walk you through advanced troubleshooting or discuss repair or replacement options if the phone has a hardware problem.

If you forget your PIN or pattern before doing a factory reset, you'll be stuck — the phone won't let you proceed without entering it. If this happens, contact Samsung support with proof of ownership. They may be able to help you regain access, but the process can take time.

Frequently Asked Questions

Will a factory reset remove my Google account?

Yes, a factory reset removes all accounts from the phone, including your Google account. When you set up the phone again, you'll sign back in with the same Google account, and your apps, contacts, and photos will restore from Google's backup. You won't lose anything as long as you use the same account.

Can I undo a factory reset?

No, a factory reset cannot be undone. Once it completes, the data is gone unless you backed it up beforehand. This is why backing up before you reset is so important. If you didn't back up and need to recover files, contact a data recovery service, though recovery is not always possible.

How long does a factory reset take?

A factory reset usually takes 5 to 15 minutes to complete, depending on how much data is on the phone. The phone will restart and show a progress bar. Don't turn it off or remove the battery during this time. After the reset finishes, setup and restoration from backup can take another 15 minutes to an hour.

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

No, you don't need to remove your SIM card. A factory reset only erases the data stored on the phone itself, not the SIM card. Your phone number and carrier information will stay the same. You can leave the SIM card in the phone throughout the entire process.

What's the difference between a soft reset and a factory reset?

A soft reset (restart) turns the phone off and back on, clearing temporary data from memory but keeping all your files, apps, and settings. A factory reset erases everything and returns the phone to its original state. Use a soft reset first for freezing or slowness; only do a factory reset if you're selling the phone or have serious problems a restart won't fix.
