Android system is developed based on linux, and also has root permission, which can access and operate all system files.

Benefit 1: After root, you can delete some unused or less used mobile phone's own software, so as to avoid those software enabling background update, occupying the mobile phone's memory and slowing down the mobile phone's running speed. Benefit 2: Many applications can only be used after root. Using these applications after root makes it more convenient for us to use and manage mobile phones. There are still many benefits, because the power to become a super user after root is too great, and any software can be deleted, so when using it, be careful not to delete some necessary software of the system, resulting in system errors or instability. The disadvantage is insecurity.
