X, formerly Twitter, introduces audio and video calls on Android. Previously available for iOS, this feature now extends to Android users. Users with an X Premium subscription can make outgoing calls, while those on the free tier can receive incoming calls only. The calling settings, found in the DM settings tab, allow users to manage call preferences, such as restricting calls to people in their address book, verified users, or accounts they follow. More information on audio and video calls is available in the X Help Center.
