Hi i dunno why this happening now. When i play my game in my android phone i cant jump while i’m using the joystick to move. they interfere each other. This didnt happen before :S. Im using the mobile single stick prefab from the standard asset.
For those that are having the same problem: You have to delete de EventSistem and make a new one.
This happens becouse they changed that in one of the new versions.
I hope that helps
