The symptoms were confirmed with the cable connected to the USB port replaced.
In either case, only the rear camera image crashes, and then K2S restarts.

A video of a terrible bug I encountered.

K2S cannot decode the incomplete encoding of the rear camera, causing the process tree to hang.
Since the process tree hangs up, it is in a state of repeated restarts by the watchdog timer.
The cause of the broken rear camera encoding is due to an accidental defect in the camera element or an incidental defect in the encoding LSI built into the camera unit.
However, both the seller and the manufacturer insist only on the opinion that the product is perfect. And it doesn't admit any initial failure of the camera unit.
Even if you request replacement and reshipment of the camera unit that is causing the initial failure, the official seller will only ask for additional costs.
Manufacturer and seller opinion
=====
The camera was tested very careful and several times, sensor is not so easy to have problem.We still think that the issue is the connection
=====
My opinion
=====
An expensive product that does not move due to malfunction.
Therefore, I feel anxious.
Since the mini0805 that I used regularly was too perfect, I will compare the completeness of the products.

The fact that a personal shipping fee is required to replace the rear camera that stops when connected is also a cause that I do not understand.
I want you to understand.

@Rayman
If you are an engineer, you should be able to understand from this situation that the initial failure of the camera unit (probably the encoding processor) is the trigger for the crash of this video.

There are also other potential defects.
He claims "There are 4pcs K2S run without GPS in our testing vehicle".
It only claims that the product is normal, but has not performed various verifications.
Highly reproducible bug I confirmed
Front EV 2/3, Rear EV 1/3
Front: 720p 60fps Rear: 720p 60fps
Situation: When K2S is turned on in the dark at night.
In this case, if the front and rear are at 720p 60fps, the rear gain will be much higher than at 1080p 30fps, and the LCD will be in white noise only.
With the current firmware, the parameters for rear exposure are fixed with the power on in this situation.
Since all rear camera exposure compensation is disabled, the camera's video output gain is increased and the LCD is in a state of white noise only.
However, I do not know the relevance of this bug.
***
When I point out a bug, most sellers and manufacturers dislike it.
(Don't accept the truth, leave it alone)
From the manufacturer's point of view, i may look like a “technical claimer”, but this shows that it can be a good product if improved.
In the first place, I don't point out bugs in products that have no future, so I find this product worthy.
I want various people to understand.
Thank you carefully.
