The new android update vanished the pad buttons and touch is is not working on saved file (23+ hours gameplay) only show if I start a new one and if I load the file it vanishes....
You should be able to reset the mobile control using the wrench icon in the phone
Or just start from the latest content when starting a new game
I tried the wrench icon, didn't worked, said was nothing to use it...
Seems like the new game will be the only choice
