How to use Galaxy S20 recovery mode?Galaxy S20 recovery mode allows you to access some very special and advanced features to manage, hack and reset Galaxy S20.

This Galaxy S20 guide explains what Galaxy S20 recovery mode is, when you need to use it, how to reboot into the recovery mode, and how to navigate and exit the recovery mode.
