The first thing you should do with your new Android device | AndroidGuys. When I left my Android phone in a restaurant while attending CES in Las Vegas several years ago, SWMBO and I had a great adventure following its location on my notebook computer during a fun taxi ride through the busy late night downtown traffic. I was using Lookout Mobile Security at that time; but, Google has since allowed the tracking of a lost Android device through the FindMyPhone app. You should download this app first if you have a new Android phone; but, it is never too late. At least, unless your phone has already been lost or stolen. Do it now. Do it today. Just do it.
