I spend some more time trying to find my Android savefiles. But thats´s tricky on Android. You need to root your system first to have full access on filesystem. Rooting Android is a security risk, you also loose your warranty, some other apps could deny their work and updates could be more work to do. There is also a way without rooting by using the ADB (Android debug bridge) and control the Android from another computer. But i have noticed, when i start from a savegame it takes same time to start, so it´s no different here, if you start a new game or try to load a new game.
