My XZ1 Physical shutter button suddenly misbehave. Was fine in the morning and then, took out to take a picture in the evening but I was only able to launch the camera using the physical button, i am unable to half press to focus and full press to take the picture. Tried to restart and shut down and run diagnostics. Diagnostics say the physical shutter works perfectly but it doesn't. Anybody know what happened? I need help!!!
