While not particularly popular in the consumer sphere as of late, push-to-talk has been a boon to those in industries where direct communication is vitally important. That functionality, however, has so far been limited to a very select number of relatively bulky phones.
But that may be about to change. The Verge has a leaked screenshot that says that Sprint's Direct Connect functionality could soon be coming to Android smartphones in the form of a dedicated client.
With the move, Sprint will not only expand the reach of its push-to-talk offerings, but it will do so to devices with vastly more attractive, touch-based interfaces. It's a smart move, and proof, probably, that Sprint realizes that its push-to-talk efforts are in need of a bit of updating.
