Barely hours after the Facebook Messenger app launched, hackers managed to find traces of a video chat feature that appears to be under construction.

The finding was first reported by 9-to-5 Mac; How to Arena later confirmed similar video chat findings in the Android version, PCWorld reported.

The video chat does not seem to be functional yet. It was only Tuesday that Facebook announced Messenger for Android and iPhone devices, which features instant messaging to friends or groups and photo and location sharing. A Blackberry version will be available soon, Facebook said.

It is speculated that the mobile video chat service would be linked to the Skype-powered video chat feature built into the Facebook Web site, but there is no official word from Facebook regarding any plans for such a mobile app addition at the moment. In July, Facebook launched video chat in partnership with Skype for Windows and OS X users.
