Hello,
I have an identical problem. The manufacturer claims that you should take the camera from the car with the holder (!), Because there is a battery there. But .... a friend bought the same camera in May 2017 and there is no problem with it. I contacted the producer again and said that they improved something and now he supports me, but I have an old version (from December 2016) and I am not entitled to an exchange. I advertise with the warranty at the seller, let him "buja" with the producer. According to me, two identical cameras can not work differently, and the producer tries to shirk.
Please note the important thing. If the memory card is full if you do not set the clock and after removing the camera will return to the initial settings (at me 1.1.2016), the next videos will be erased immediately because they have (!) The oldest date. I realized just when it turned out that I did not have an evidence film, and all the films I had from a few months ago.
I recommend stubbornly advertising at the manufacturer or seller, because not all copies have it.
Greetings.
