Looks like issue 2) is also discussed here

I also found a video describing the issue
Dear all,
I purchased one month ago the Viofo Camera, and I'm very happy with it.
I'm facing two issues when I get in the car after parking.
Please note that theseissues persists also when the car is turned on.
1)
I see that the camera is unresponsive.
The screen is dark, no led is blinking...
