Had it when using the camera for a couple of minutes in manual mode and then taking a 3 minute 4k video. Took it back to CPW this afternoon and they asked me to show them the problem, happened again within 3 minutes of just using the camera. They tried it on another Z5 and same thing. This is with absolutely nothing else running on the phone.
Nope, not on mine, not sure where CPW would get a spare z5 from either. Stock of new phones is treated like gold dust.
Funny how none of the reviews mentioned it either...
