EA just send an update for android but it does not work. They left the timer on madness events so it crashes. I have two devices and their fix does nothing.
Unistall the game, install again, go to campaigns madness and on 90% chance you will find one icon active. Click on it, and then repeatedly play all your stamina without exiting the event. You can swipe left and right to find 25, 50, 75 stamina.
This works only once but you can always repeatedly install/uninstall.
