AT&T customers who install the new Google Hangouts application on Android devices cannot use one of the main features: video chats.
The feature won't work on AT&T's
AT&T explained that
AT&T customers are free to download any third-party video chat app
they wish and they'll work fine.
Apps that come preloaded, however, must
be enabled by the developer for use over AT&T's cellular network. Google did not follow
the proper protocols required by AT&T in order for the app to
function over its cellular network.
Google Hangouts for iOS, which
qualifies as a third-party download on the iPhone, functions properly
over AT&T's cellular network.
Google Hangouts for Android works fine
on all other cellular networks except AT&T.
