Why is the third party's right to read short messages gone?

The reasons why the third party's permission to read short messages is gone are as follows:

1, the root privilege obtained on the mobile phone is an unstable version. Reuse the tool to obtain permission. Just go to your cell phone.

2. After entering the advanced center, find the security protection of the verification code, and slide the button next to it to turn green to open the third party to receive information.
