Similar problem reported here https://dashcamtalk.com/forum/threads/settings-not-saving-after-power-off.31322/ resolved by loading boot loader first. Usually boot loader not needed unless version prior was before V2.0, but who knows? Read the thread and decide.i give up with this beta firmware,i have uploaded and re upload multiple times and still won't save my settings, going back to 3.3 for now.
interesting artifacts around the lights caused by the two different exposures... imagine how much worse the offset would be in the car's headlights (and lights on the buildings) if you were going faster - that'd look weird in a freeze frame like this.OK, time for thoughts after few days of using HDR mode.
It definitely improves quality of image in terms of suppressing "blown" sky. Image is more acceptable.
However it does not improve the readability of plates at dark. I drove about 10 km\h and vehicle on my course also about 10 km\h. Both we had together 20 km\h but yet camera was unable even in minimal degree to read plates. It happens at dark and dusk. Generally in all situations where there is not bright day.
I live in EU, where car's plates are quite big.
I think the blur is the problem. 60 FPS won't do much in this case.
The HDR will improve the readability of the plates if you get the plates in the beam of your headlights. If they are bright enough then they will be readable, if they are too dark then it will be using the slow exposure and they will be motion blurred. Without HDR you would only have the slow exposure so they would always be blurred, or over exposed.However it does not improve the readability of plates at dark.

To improve the low light issue, one needs a larger lens, and a larger sensor. Larger sensors are more sensitive to light (more surface area to capture photons), and larger lenses capture more light. There is a trade-off though, a larger aperture will reduce the depth of field, it can only focus at one distance at a time. Things further away, or closer than that distance will be out of focus.
That being said, one could probably double or triple the size of the current lenses without running into depth of field issues.
Unfortunately bigger lenses and sensors are more expensive, and would make the cameras larger.
I'm speaking mostly from the viewpoint of a slow or stopped vehicle
The most noticeable difference will probably be that it doubles the motion blur with the CPL fitted, although when you have plates illuminated by your headlights and HDR turned on, the HDR probably still uses the same exposure time for the bright areas thus resulting in the same motion blur anyway and you would only see a difference to the amount of motion blur in the darker areas which probably doesn't matter much.I just installed the beta firmware yesterday, it saves my settings fine until now and it seems there are no bugs either..
will be trying the HDR function at night and morning.. question tho, is it better to remove the cpl filter at night or just leave it there all time? does it affect the lightning on the video somehow?

Try it on and off and let us know what you find
