Samsung Galaxy Mobile: How to perform a factory reset?

Last Update date : Apr 28. 2021

A factory reset, also known as a hard reset or master reset, is an effective, last resort method of troubleshooting for mobile phones. It will restore your phone to its original factory settings, erasing all your data in the process. Because of this, it’s important to back up information before you do a factory reset.

 

There are lots of reasons why you might want to Factory Reset your Samsung device. Whether you're giving your phone to someone else and you don't want them to access your information, or maybe you're having trouble and need to start from scratch.

Forgotten Lock Screen Security:

If you're trying to reset your device because you've forgotten your lock screen security, there are a couple of options to reset your device remotely. With both of the following options however, the device needs to be turned on, and it needs some kind of network connection; whether it's connected to a Wi-Fi network or mobile data. If you're locked out of your device it will mean you'll only be able to restore information that has already been backed up. 

 

Both of these methods will require you to log into your Google account when the device has reset. This security is built in to keep your device and information safe - if your phone is stolen, a simple factory reset will not allow anyone to use your device or gain access to your accounts or information.
