I have it on my S3, is very stripped down (No team talks, press conferences etc), Training is just I think 6 options, Tactics are cut down (Have all positions, roles, and then about 6 team instructions), and you can only load one nation (Due to having to support older Android phones, Marc is looking at making 2 Android versions in future).
I really enjoy it though, have played through three seasons in the A-League, and also a few more seasons in other leagues, it is quick and also still a lot of the fun from the full game is there. If there is anything you want to know then ask away and I'll try answering.
