GoKawiilWhen Apple released iOS 26 in September 2025, the update brought a useful call screening feature to your iPhone that can help block spam calls on your device. The update also includes a feature that can filter out texts from unknown senders, which can help keep your inbox spam-free.
With this feature enabled, those messages will be filtered to their own folder in Messages without notifying 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 text screening feature on your iPhone in a few easy steps.
