Why do many Android softwares read SMS records, call records and contact information?

Android devices need to obtain device information, read location information, read call records and read SMS records. This is a function that the software can use. For example, navigation software will use positioning. If positioning is turned off, the related functions of navigation and positioning cannot be used. Communication software sometimes needs to read call records and SMS records. Information refers to the objects transmitted and processed through audio, news and communication systems, and generally refers to all the contents spread by human society. People can distinguish different things by obtaining and identifying different information from nature and society, so as to understand and transform the world. In all communication and control systems, information is a common form of communication.
