How does iphone realize automatic sorting of notification messages? Also known as SMS folding function.

1, Apple's mobile phone itself can't be realized, and it needs the help of third-party software. However, under the condition of not jailbreaking, the security of Apple's system will not allow third-party software to organize such private things as short messages. If you escape from prison, your privacy will not be guaranteed.

2. My suggestion is that when users store the number starting with 106 (or some other number) in their address book, it is assumed that users attach importance to the short messages sent by this number. Such numbers stored in the address book should not be folded again.

Similar to the mail system, when the sender is stored in the address book, the sent mail will not be judged as spam.
