Microsoft has started testing Xbox party chat in the company’s Xbox mobile apps for iOS and Android. The beta Xbox app for Android is available immediately with the party chat support, and you can sign-up to test party chat on iOS using Microsoft’s form.
Party chat inside the Xbox mobile apps lets you voice chat with friends on Xbox Live, similar to the Discord mobile app. It’s a useful feature if you’re not near your console or PC, or even if your headset isn’t working correctly on those devices. Microsoft typically brings beta features to its main Xbox apps within a few months, so it should be available to both the regular iOS and Android apps shortly.
