I recently bought Grand Theft Auto:Vice City for Android and installed it on my Samsung Galaxy S2 (SGH-T989) running Samsung's release of Android 4.1.2.
The game hangs as soon as I try to drive a vehicle. It will resume after a few seconds, but the end result is two to three seconds of drive time between 30 and 50 second freezes. Adjusting the video options fails to change this behavior. Rock Star has a thread about this bug on their support site that admits this is a known problem with several phones, including the T989. Frankly, I consider it false advertising to claim the Galaxy S2 is supported when it clearly is not.
