Samsung has been championing its own messaging app or potential platform for quite a while now. In the last few months it has added a whopping 50 Million to take its total number of users to over 100 Million. ChatOn comes preinstalled in the majority of Samsung's phones.
Google has recently added the SMS option onto Google hangouts, which is something that Android users have been screaming out for. So Samsung has decided that it should do the same for ChatOn, but it has integrated not only SMS, but also MMS for Samsung devices on Android 4.0+
Users are able to see text messages as part of their usual ChatOn messages. The updates is now available in the Play Store.
