I can't believe it, how they manage to be in play store and beat all the security process? That's very odd, to think that the real chat deny having any app and yet their app is on play store, this should be reported immediately before lots of people fall victim.
Back in my XDA forums days and being an Android enthusiast, it's because when the app is uploaded, it has no dangerous or alarming code***.
After approval and a successful listing, developers will now put a mandatory update to that application and that contains those malicious codes.
But that knowledge of the mind was around 5-6 years ago and GooglePlay should at least improved their system now to track down
sh*t applications. GooglePlay is not really a 100% safe platform. Because of this, users themselves should need to adjust.
