Need to choose a new mobile device for work.  I am strongly considering an S8 after a lifetime of iPhone use, but procrastinating.  The new iPhone 7 or 8 just doesn't do it for me, as much as I like iOS and the security and consistency it provides, the handsets and screens on casual observation pale in comparison to the S8 offering.  Expandable memory and a headphone jack (which I use regularly in different situations) are also dragging me towards the S8.  

An iPhone 10 is out of the budget, and not sure I would choose it anyway. Apple are very 'meh' these days (as my kids say).      

I have read the other threads on here about changing and they have been very helpful, thanks to those that contributed, some really constructive suggestions and honest feedback, and I now understanding the benefits and pitfalls better. 

One question I cannot find an answer to...the rest of my family is heavily invested in iOS devices and everyone else will be using an iPhone or iPad.  A big value with iOS is having the 'find my iPhone' app which we all regularly use.  Is there a way for an iPhone user to track the location of an Android user, and vice versa (providing permissions are given of course)? 

My Google-fu reveals both yes and no answers.  I would have thought a browser with appropriate access to the Apple or Google account would have been able to do this but apparently Apple iCloud won't work with any Android browser.  There are a couple of app suggestions but they don't look like anything I would immediately trust.    

Any suggestions how this could work?  Can it work?  If I can get over this barrier I think I am there.
