Apple 1 1 Set to block harassing messages.

Open "Info" and you can see the obvious changes:

1) information classification class;

2) Click the "Information" setting at the bottom to jump to "Filter Information".

On iOS 13.3, the specific changes include:

1) Inbox grouping

Turn on the information function and you will see this change. This interface is a bit like email, and the information is divided into several categories: all information; Known sender (talking to contacts in the address book or replying to the sender's conversation); It's not in the address book

2) Add spam inbox

It is similar to the junk inbox of the mail system, but it is not separately placed under the information function. Click the "Information" setting at the bottom to enter this junk inbox.

What kind of information will enter this junk inbox? A) an iMessage sent to you by an Apple ID (that is, a stranger) that is not in the address book or the user has not replied; b) an iMessage sent by a user (that is, a person who has refused) who has sent a message to the receiver before but the receiver has deleted the previous conversation; -These two kinds of spam are very common in "Macau Casino".

In order to prevent misjudgment, in the above cases, the sender will receive a prompt telling them that the recipient may not have seen his information. This is done to prevent normal information from being intercepted by misjudgment.
