Excuse me, some mobile phone software, what is the use of obtaining permission to modify short messages?

It must be clear whether it is the right to "modify the short message" or the right to "obtain the content of the short message"

It is reasonable to say that there will be no permission request methods such as modifying short messages, and some systems will not allow applications (software) to use relevant permissions. For example, Android 6.0 has banned third-party applications (software) from getting short messages.

Only the lower version of Android (6.0 below 6.0) will have such a requirement, depending on the application (software). Some security software needs SMS verification-such as (QQ, security manager). General software will give corresponding prompts before requesting permission.

But be sure to pay attention to the request to modify the message. Many malicious software (applications) modify the content of short messages to deceive users.
