“Trick” allows iPhone users to hide messages sent by unknown senders

Now that you’ve set up this feature, the next time that you’re in the Messages app, click on Filters in the upper left corner. That will result in three different options you can choose to filter your messages: All Messages, Known Senders, and Unknown Senders. If you want to clean out your inbox and hide messages from senders you don’t know, select Known Senders. This will allow you to view only those messages sent by people and organizations that are familiar to you.

If you want to resume viewing all messages regardless of who sent them, tap on All Messages. And if you want to (for some strange reason) view only messages from senders unknown to you, tap Unknown Senders. The option you tap on last before leaving the Messages app will be the default setting unless you go back in and make another change.

If a tidy Messages inbox is important to you, it shouldn’t take you more than a few minutes to enable the feature and set your filter.
