I’ve searched the forums on the topic and I have only found the opposite issue.
When I am playing the game on mobile, during long cascades by the enemy or times I take a moment to do things, my phone will go to sleep instead of staying on the game. I have checked and the power save option is unchecked… I have even checked it just to see if the setting might be backward.
Other mobile apps (games mainly) do not allow the phone to time out, this only happens in Gems of War. Any ideas why this is happening?
