It’s been a good run, but any device running Android 2.2 through Android 2.3.7 (all versions of 2.2 – 2.3) will no longer be supported in future updates of any of my games. It’s not actually me, it’s Google that doesn’t support it as of August 1st, those phones are 6 years old (ancient in technology!) .. so if you still have one of those, there are two options for you: upgrade to a newer phone, or see about adding a custom OS to your phone. Options ARE available, and I’d be willing to lend a hand in links for phones, if you need help upgrading or getting a custom OS like ClockWork Mods working, I might be able to point you in the right direction. On the other hand, you can get a phone cheap at Walmart, Best Buy and Target (in the USA) so it’s not a whole lot out of your pocket to upgrade.
Phones should be running a MINIMUM of 4.0 for future game releases. (Tablets 3.0 and above)
