This is basically malware designed to trick the non-tech savvy -- who either don't know where their SMS app is, or are looking for Facebook Messenger -- into installing this utter garbage. Most Android users don't know what a "launcher" is, so when they find this application, they ignore that part. And they don't notice the fine print that says "contains ads and in-app purchases." This is the Android equivalent of a scumware browser-hijacking extension. It should be banned from Google Play.
