I was trying to mirror my Android smartphone to my Samsung TV to show a webpage to someone. This feature is called "Smart View" in the TV's menu, but I didn't know how to connect, so I searched that name in the Google Play store. There are dozens of results, only one of them is the official app that has any chance of working. There are two apps[1][2] that actually appear to be the same app just with slightly different names presumably so they appear twice in the search results. One app[3] has some very suspicious ratings and I can't help but notice that the publisher's name is "SmartThings.net" which appears to add more credibility until you see the domain has nothing to do with the app. I understand it can be hard for Google to vet these apps but some of these failures (like verifying you actually own the domain you are pretending to be affiliated with) seem like they could be automated.
