Okay, I put my Caanoo in my pocket to carry around and stuff and I noticed one day that the joystick was kind of wobbly. I played with it a bit and it went into place and was normal. It has done this a few times now and went back to normal except for today. No matter what I do, the joystick will not quit being wobbly. When I push the joystick all the way to the left, It wont go back to center position without me pushing it there. Is there a trick to getting it back in place?
