The issue I have is the OS levels and the Android levels on the older phones including the Z20 and others is not beng updated and from what I can find can be done to allow the phones to use some maybe not all newer apps.
As I have said in other posts the lack of current Android ability with the Z10 and others is allowing Google to block the downloading of newer apps such as the latest Onstar Mylink app. Google will not even allow a download and checks Android version before you can even sign up for service with Goggle at least in my experience
The ability to track and send apps relating to the users location may just be the real reason along with the push to force sales of updated phones on users.
