Samsung's ChatOn messaging app is already available across multiple platforms, but it faces stiff competition from similar services such as Kakao Talk, which remains hugely popular in its native South Korea. Samsung could be stepping up its game in this space, however — according to DDaily, the company is developing a video chat service that will let you talk to your ChatOn contacts over 3G or 4G mobile networks as well as Wi-Fi. The video functionality is reportedly set to debut on Android first, but Samsung could subsequently bring it to other platforms.

While it wouldn't be the first cross-platform 3G video chat service, with apps like Fring having provided similar functionality for years, it could make a splash even if restricted to Android. An anonymous Samsung employee told DDaily that "nothing has been decided" about the possibility of pre-installing ChatOn on the company's smartphones, but it'd be an obvious rejoinder to Apple's cellular-compatible FaceTime in iOS 6.
