A superuser is a person who has access to all the features of the Android operating system. And to be a little more precise, this term is also called special rights. Usually, they significantly expand the possibilities of interaction with the smartphone. With their help, you can easily install new firmware on the phone, uninstall the system applications, work with the bootloader, and access the system folders.
You need to perform some actions to get such an honorable status as a superuser. But before starting the procedure, you should understand that the phone, after obtaining root rights, is automatically removed from the warranty and, as a result of improper actions, can turn into a “brick”. If such consequences are not frightening, more details about obtaining root rights are described here. Carefully read the possible restrictions, and only then proceed to perform the actions from the instructions!
