Factory Reset Options When Your Samsung Is Locked

If your Samsung phone is locked and you need to wipe it back to factory settings, you have three main paths: using Find My Mobile (Samsung's account recovery service), performing a hard reset using hardware buttons, or using Android Device Manager if you set it up before the lock. The method that works depends on whether you remember your Samsung account password, whether the phone will still power on, and what you set up before it locked.

A factory reset erases everything on the phone — all photos, messages, apps, and settings. Once you start the process, you cannot stop it partway through. Make sure this is what you actually need to do, because the data cannot be recovered afterward.

Key Takeaways

  • Find My Mobile is the fastest route if you remember your Samsung account email and password — it can unlock and reset the phone remotely without using the phone itself.
  • A hard reset using the power and volume buttons works on any Samsung phone that turns on, even if you do not remember your password, but it erases everything.
  • Android Device Manager can unlock and reset your phone remotely only if you turned it on before the lock happened and you still have access to the Google account linked to the phone.
  • After any factory reset, the phone will ask you to sign in with a Google account before you can use it — this is a security feature called Factory Reset Protection.
  • If the phone will not turn on at all, a hard reset using buttons is your only option, but it requires holding specific button combinations for several seconds.

Using Find My Mobile to Unlock and Reset Remotely

Find My Mobile is Samsung's own account service, and it is the simplest route if you remember your Samsung account credentials. Go to findmymobile.samsung.com on any computer or another phone, and sign in with the email address and password you used to set up your Samsung account on the locked phone.

Once you are signed in, you should see your locked phone listed. Click on it, then look for the option labeled "Unlock My Mobile" or "Factory Reset" depending on your phone model and the current firmware version. Samsung will send a confirmation to your registered email address — check that email and confirm the action. The phone will unlock and reset within a few minutes, even if it is powered off.

If you do not see your phone listed on Find My Mobile, it means the phone was never registered to your Samsung account, or the account was set up on a different Samsung account. In that case, move to the hard reset method below.

Hard Reset Using Power and Volume Buttons

A hard reset works on any Samsung phone that will power on, regardless of whether you remember any passwords. The button combination varies slightly by model, but the most common sequence is: power off the phone completely, then hold the Power button + Volume Up button + Bixby button (or just Power + Volume Up on older models) until the Samsung logo appears. Keep holding for about 10 seconds after the logo shows, then release.

The phone will boot into Recovery Mode, which shows a menu with white text on a black background. Use the Volume Down button to navigate to the option that says "Wipe data/factory reset" or "Factory reset," then press the Power button to select it. The phone will ask you to confirm — navigate to "Yes" and press Power again. The reset will take 2 to 5 minutes.

After the reset completes, you will see "Reboot system now" highlighted on the screen. Press Power to restart the phone. It will boot normally and ask you to set up as a new phone, including signing in with a Google account. This is Factory Reset Protection, a security feature that prevents someone else from using your phone after a reset — you will need to sign in with the Google account that was on the phone before the reset.

Using Android Device Manager for Remote Reset

If you set up Android Device Manager (now called Find My Device in newer Android versions) before the phone locked, you can use it to reset remotely. Go to google.com/android/find on a computer and sign in with the Google account that was linked to the locked Samsung phone.

Select the locked phone from the list of devices. You should see options including "find your device" or "Erase your device." Click "Erase your device" to wipe the phone and reset it to factory settings. The phone does not need to be powered on — Google will send the command and the phone will execute it the next time it connects to the internet.

After the erase completes, the phone will ask you to sign in with a Google account during setup, just as it does after a hard reset. You will need the Google account that was on the phone before the erase to proceed past this screen.

What Happens After Factory Reset: Factory Reset Protection

Once your Samsung phone resets, it will power on and ask you to set up as a new device. Before you can use the phone, you must sign in with a Google account. This is Factory Reset Protection, a built-in security feature that locks the phone to the Google account that was on it before the reset.

If you remember the Google account email and password that was on the phone before the reset, sign in with that account and the phone will unlock completely. If you do not remember it, you have a few options: try common passwords you may have used, check your email recovery options if you have access to the recovery email address, or contact Google's account recovery service at accounts.google.com/signin/recovery.

If you cannot recover the Google account and the phone is yours, you can contact Samsung Support with proof of purchase. They may be able to help you remove the protection, though the process varies by region and Samsung may require documentation.

Troubleshooting When the Phone Will Not Power On

If your Samsung phone is completely dead and will not turn on, try charging it for at least 30 minutes before attempting a hard reset. Some phones will not respond to button presses until the battery has enough charge. Use the original Samsung charger if you have it, or any USB-C charger if your phone uses that port.

If the phone still will not power on after charging, try a hard reset anyway — hold the button combination for 15 to 20 seconds instead of 10. Some phones will boot into Recovery Mode even when the screen appears completely dark. If nothing happens after 20 seconds, the phone may have a hardware problem and will need service from Samsung or a repair shop.

When to Contact Samsung Support

Contact Samsung Support if you have tried both Find My Mobile and a hard reset and neither worked, if the phone will not power on at all after charging, or if you are locked out by Factory Reset Protection and cannot recover your Google account. You can reach Samsung Support through their website at samsung.com/us/support (or your country's Samsung site), or by calling the number on the back of your phone or on your original receipt.

Have your phone's serial number or IMEI ready — you can find the IMEI by dialing *#06# on any phone, or by looking at the original box or receipt. Samsung may ask for proof of purchase before they can help you remove Factory Reset Protection or unlock the phone.

Frequently Asked Questions

Will a factory reset remove the lock screen password?

Yes. A factory reset erases all settings, passwords, and data, including the lock screen PIN or pattern. After the reset, the phone will ask you to set up as new and sign in with a Google account, but there will be no lock screen password until you create one during setup.

Can I factory reset a Samsung phone without losing my data?

No. A factory reset erases everything — photos, messages, contacts, apps, and all settings. There is no way to reset the phone and keep the data. If you need to keep your data, you must find another way to unlock the phone without resetting it, such as contacting Samsung Support or the phone's original owner.

What is Factory Reset Protection and why does it ask for a Google account?

Factory Reset Protection is a security feature that prevents someone from stealing your phone, resetting it, and using it as their own. After a reset, the phone locks to the Google account that was on it before the reset. You must sign in with that account to use the phone, which protects your data even if someone else performs a factory reset.

How long does a factory reset take?

A hard reset using buttons takes 2 to 5 minutes from the moment you select "Factory reset" in Recovery Mode until the phone reboots. A reset through Find My Mobile or Android Device Manager may take up to 10 minutes if the phone is powered off, because it must wait for the phone to connect to the internet to receive the command.

Can I undo a factory reset?

No. Once a factory reset completes, the data is gone permanently. There is no undo button and no way to recover the erased files. If you have a backup of your phone from before the reset, you can restore from that backup after the phone is set up again, but only if you backed up to Samsung Cloud or Google Drive before the reset happened.
