The Google Phone app introduced a feature called Calling Cards in August, allowing users to create a personalized screen with a photo and custom text that appears when a contact calls. As of March 3, an update enables these Calling Cards to be visible to the people being called, rather than just the creator. Users can create their Calling Cards by accessing the settings in the app, selecting a photo, customizing text with various fonts and colors, and adjusting sharing preferences. The rollout of this feature may be staggered across devices, and users should ensure their app is updated to the latest version to access it.
