I'm not sure why that would be happening, but I can certainly investigate that for you.
Which version of the game are you playing? The Demo or full game?

Sorry, I've loaded up the game in an android test environment, and then again on a physical android phone but I haven't been able to replicate your issues. The best I can really do is advise you to redownload and reinstall the game, and see if that helps. If issues persist, please try the demo instead and see if the same issues occur, because it may just be your device.
Cheers.
