What phone? Android version? How many RAM? What version of the game?
Also if you have time please visit our discord and contact benq666, you will need to do a couple of actions that will help identify the problem, it willl require installing developer tools and should probably take about 10 to 15 minutes in total. We can't sadly check this on our own since the game works fine on all our devices that we used to test the android version on.
