After using the photo mode after about 5 times, whilst driving, same session, it stops working, trying to enter photo mode when driving a train, or on foot....once in BCC and now in LNER, it just not want to function. I have noticed when photo mode is reset, and you try to adjust the focus, it does not work at all, not even when you reset it. OK it does not happen all the time, but I would say about 30-40%
