Pity about the quality

I have bought because of the many positive reviews of 0801 and loved it. Now, since I wanted to buy a second, for the front and back, I have decided for 0803.
Which errors are noticed:
- On the case was held 0801 0803
- The video quality left a lot to be desired, automatic white balance (too dark compared to 0801)
- On the screen of 0803 I saw the brake lights flicker from the front man, thought to myself at nothing until I've looked at the video. On the video, the brake lights have also flared.
So the dashcam went back again
Either only the part was defective or the entire 0803 series ... are just speculations ...
