Yes. I have a Samsung Android and since the expansion, the virtual joystick goes nuts and the charge buttons fire erratically when you hold the charge down. I complained about this immediately after the expansion and nothing has been done to fix the issue. I know several people in the guild I'm in that are having the same issues, and have met dozens of people in the game zones that are experiencing it as well. It has caused me to die tons of times and causes unnecessary potion usage to survive. It's ridiculous.
