Hi my watch started going haywire during a run. I was unable to stop it scrolling left or right or up and down with the joystick if I can call it that. Eventually it ran out of power then would not take any charge through my mains adaptor. I got it connected to my laptop when I got home from holiday and it seemed to download Okay but does not display the recharging symbol. It must be taking some charge as I can disconnect without showing the fully discharged symbol. When disconnected however the joystick does not work so its stuck just in watch display mode. Any thoughts anyone?
