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, and return it to the same settings and information it contained originally.

 

Most people will perform factory resets on their device either to solve persistent software issues or to ensure that all personal data is removed prior to passing the device to someone else.

Google device protectionClick to Expand

If you have a Google account on the device, make sure you know the password before resetting.

Google Device Protect is a safeguard which prevents others from using your device (if lost or stolen for example) if they reset your device to factory settings without your protection. You will be asked to enter your Google password to access the device after resetting.


If you want to turn off device protection, remove your Google account from your device before resetting.


Factory Reset methods

There are three main ways to perform a factory reset: via the Settings menu on your device, using the buttons, or by using the Find My Mobile service.

Performing a Factory Reset via the Settings MenuClick to Expand

PLEASE NOTE: if you have a Google account on your device, you may have Google device protection (this is in place for most later operating systems). This prevents unauthorised persons from being able to use the device by simply resetting it if it is lost or stolen. Make sure you know your google account password before performing the reset.

The location of Factory Reset in your settings will differ slightly depending on the model and operating system of your device.


Settings > General Management > Reset > Factory data reset


Settings > Backup and reset > Factory data reset


Settings > Privacy > Factory data reset

Using Find My MobileClick to Expand

Find My Mobile allows you to locate, lock and/or wipe your device remotely among other features. You will need to have set up the remote controls feature on your device before using the Find My Mobile service.

PLEASE NOTE: if you have a Google account on your device, you may have Google device protection (this is in place for most later operating systems).

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

1 Switch off the device
2 Press and hold the Volume up button, the Power button and the Home button at the same time.

4 A screen menu will now appear. When you see this, release the remaining buttons
5 Use the Volume down button until you are highlighting 'Delete all user data'. Press the Power button to select.
6 Press the Power button again to select the Yes - delete all user data option
7 Press the Power button to highlight, then select the 'reboot' option
