What software does Android phone have to control SMS sending?

Android phones have security auxiliary software that can control the sending of short messages, and need to obtain root permission. Security auxiliary software includes Baidu Guardian, mobile phone housekeeper and so on.

Root privilege is a kind of system privilege, which can be understood as the concept of having system privilege, but it is higher than administrator privilege. Root is a super administrator user account in Linux and unix systems, which has the supreme power of the whole system and can operate all objects. Therefore, when many hackers invade the system, they should upgrade their permissions to root permissions, that is, use windows to add their illegal accounts to the Administrators user group.

Administrator is a super administrator user account in Windows NT kernel SYSTEM, and also has extremely high authority, and the system user group can be understood as the authority of the computer system itself. You can manipulate all objects and all processes.
