Comments: Needed someones help in enabling the double coin booster for Subway surfers. I already have the 1.5.2 version of the game which has unlimited money and all characters enabled but it doesnt have the double coin booster enabled. The game is not in my play store list as i have installed the unlimited money version via a file explorer i cant buy the double coin booster. My phone (galaxy nexus) is not rooted hence i cant use any cheat engine for the moment. Can anyone help me out. All help will be appreciated
