When I typed in Facebook in the app store, it also displayed Facebook for iphone 6s. I thought this would be specific to iPhone 6s but its not. It is an app called Friendly. I didnt like the way the layout was on the app as I prefer the layout of the "real" FaceBook app. Nevertheless, because of my skeptism with this app, I deleted it and within 24 hours I found a frozen apple icon on my screen. I am now unable to do anything on my iphone. Perhaps a coincidence but it didnt seem so as this whole process occurred within 24 hours and that is why I would consider this a not so friendly app.
