Hunch Media, a market analysis company based in the US, made an infographicc in which it details the personality of users of the Android OS and iOS operating systems. The infographic represents the corroboration of studies that cover over 80 million responses, but the company does not say how many people actually participated in the survey. In essence, the survey says that users of terminals with the iOS operating system are richer, smarter, have traveled more, are more intelligent, "have more fingers", etc.
There are indeed methods of doing such studies, but from my point of view, I think that some of them present information that could be completely different from reality.
