When Apple released iOS 26 in September 2025, the update included a call screening feature that blocks spam calls to your iPhone. The update also includes a feature that can screen texts from unknown senders to keep your inbox spam free.
With this feature enabled, those messages will be filtered to their own folder in Messages without altering you. Once these messages are in their respective folders, you can look through them at your own pace to make sure you haven't missed anything important, or you can delete them without a second thought.
Here's how to enable the new text screening features on your iPhone in a few easy steps.
