I'm running a two year old Droid Razr Maxx with Android v4.1.2 (Jelly Bean). I'd like to be able to take advantage of some of the new fitness devices out there, but they all require minimum v4.4 (KitKat). Can I upgrade my phone to the new version, or am I stuck replacing this two year old phone with a new one? If I can upgrade, anybody know how to make the phone do it? When I run the normal update routine it comes back saying everything is up to date.
