How do I perform a factory reset on my mobile device?

A factory reset, sometimes called a hard reset or a master reset, will remove all personal information, changes, and data from your device, returning it to the same settings and data that it had when it left the factory. The most common reasons to perform a factory reset are to solve persistent software issues or to ensure that all personal data is removed before giving the device to someone else. There are three main ways to perform a factory reset: via the Settings menu, using the buttons on your device or by using the Find My Mobile service.

Please note: Most Android devices are secured with Factory Reset Protection. This is a feature designed by Google to prevent your phone from being reset without your permission. If you intend to give your device to someone else once it has been reset, please ensure that you remove your Google account from the device first. Follow the steps under Google Device Protection for more details.

A factory reset will permanently delete all of the following from your phone:

 

  • All personal data
  • Customised settings
  • Applications downloaded from the Play Store
  • Messages
  • Contacts
  • Photos

 

Therefore, before performing a factory reset, it is recommended that you first back up the data.

Google Device ProtectionClick to Expand

Most Android devices are protected by Google's Factory Reset Protection (FRP) feature. If your device has been reset using buttons, you will be asked to enter your Google password before you are allowed access. This feature is designed as a safeguard to prevent unwanted people from using your device if they managed to reset it without your permission, for example, if it was lost or stolen.

 

If you want to remove FRP you will need to follow the instructions below to remove your Google account from your device before resetting.

 

If you want to remove FRP but you are locked out of your device, you can send your device, along with proof of purchase, to an authorised Samsung Service Center.

Please note: The steps described in this example should be followed if your device is running Android Nougat, Oreo, Pie or 10. If your device is running an older version of Android, you may need to navigate using one of the following paths:

  • Apps > Settings > Cloud and accounts > Accounts
  • Apps > Settings > Accounts > Google
1 Go to "Settings", then tap "Accounts and backup".
Tap Accounts and backup in the Settings menu
2 Tap "Accounts".

Factory reset on a smartphone using the buttonsClick to Expand

If you are locked out of your device, you can perform a factory reset using the buttons on your device.

Please note: Most Android devices have security measures in place to stop them from being factory reset if they are stolen. One of these security measures is called Google Device Protection. This means that if you have a Google account on your phone, when your phone is reset using the buttons it will ask you for your Google account information. Make sure you know the email and password before resetting. These details will be the same password and email you use for the Play Store. If you're locked out and you don't remember your Google account details, you have a couple of options:

1. If you know your email but don't know the password, use the Google account recovery tool to recover or reset it. Then, use your new password to unlock your Galaxy device. You might need to wait 24 hours (or longer) for the new password to become active.

2. If you cannot remember any of your Google account information, you can send your device, along with proof of purchase, to an authorised Samsung Service Center.

1 Switch off the device. If your device is locked, in order to power down your device you will be asked to enter your PIN, password or pattern. If you don't remember your PIN, password or pattern, your device will switch off when it runs out of battery.
2 Open the recovery menu using the buttons on your device. The button combination required to open the recovery menu differs depending on your device.

If your device has a physical home button (for example, S6 or S7), press and hold the Volume UpHome and Power buttons simultaneously.
When you feel the device vibrate, release the Power button. Your device will vibrate again and a menu will appear. When you see this, release the remaining buttons.

If your device does not have a physical home button but does have a separate Power button (for example, S8, S9, S10/S10+), press the Volume Up,
Bixby, and Power buttons simultaneously until your device vibrates and the Samsung logo appears. You can then release all buttons.

5 Your device will process the factory reset. Once complete you will see "Data wipe complete" at the bottom of the screen. Press the Power button to select "Reboot device".

Please note: It may take a few minutes for your device to reset. Wait while it reboots. It will power on automatically when it is ready to be set up. When it switches on, you will be prompted to go through the steps to set up the device as if it were the first time it has been used.

6 Once your device has rebooted, you may be asked to enter your Google password. Enter your details to access your device.
