If every action gets an equal — though perhaps not precisely an opposite reaction, at least via social video — then at least some part of that equation will be settled with the release of Samba for Android.
With Samba, you get a video from someone you know, and immediately you can use your front-facing camera to shoot back your up-to-15-second reaction to it.
You don’t need to have Samba installed to receive a Samba message, though in the past, you could not reply in kind unless you were a Samba user. That meant all Android and Windows Phone users were left out.
And now that will change. Starting Thursday Android users can be bona fide members of the Samba club and tell their friends how they really feel — right then and there.
Windows Phone users will have to wait a bit longer. The company says there’s no immediate plan to port the app to that platform, but left open the possibility that it might eventually do so.
