I'm a new user/stranger to Android on my new Samsung phone. I've been using Apple for 7 years and have decided to try out Android phone instead. While I'm starting to like it, at the same time I am concern about my privacy. I have several sensitive information from 3 different companies but it's still on my iPhone for now. If I play it safe by download app from play store only and do not click any links that could be infected with malware, should I be concern using Google or any of their apps due to their advertisement purposes?
