I play on android OS quite offten. My advise is not to download mobile app because all features are not available there. Install Puffin browser and by using it browse for normal FoE web site, and play game with all features like you would use to do by playing on home PC. It will take you few hours to get use to it, but after that you will play normaly. If you have any other question once you start, feel free to ask.
