Incoming calls break it – Airport Mania: First Flight XP Free Review

Addictive game, but if a call interrupts your game you no longer have any sound when you resume the game. The only way I've found to restore the sound is to reset the entire phone since there's no way to reset the game itself. But when you reset you lose anything you've bought for your airport so it returns you to the same level you were playing but with only 2 gates and 1 parking space etc.
