Code Version - Version Name -[/code:b95yfztd]
I tried it on a samsung galaxy S2 (pretty old phone, will test on a HTC HERO tomorrow (released 2010)) and game works fine and I don't experience any issues with "I cannot press home button"
you can test any devices, with the android SDK that is available for any developer for free, you just set your device in settings there should be a popup before testing, select the android device in this case the xperia A4 and should work, you then have a controler next to it to simulate the phones buttons and all
some xperia-z-emulator link so it puts you on the track you need.
the weird part is gplay should show you the version he downloaded unless he initialized the download then cancel it and then reviewed it. gplay has a bug on that part, noticed it on my mobile long time ago, so it might be its the first "competition" issue we avoided to take to serious in consideration, its just making more sense at this point.
however you can report the review you should have a report button. if not contact gplay support.
