...and Niko for the third half of the world (y'know, the old one).
Have some spotty biz going on over here also - it's not like the Milky Way, but was noticeable. Some of this may be because of a spotty windshield - it's not 100% scrubbed clean - but some are definitely rogue white pixels - microtrash that got inside during the manufacturing process? Some sort of "calibration" issue?
Didn't have an arrow template handy, so spots are located at the top part - upper and to the left - of the red lines. Everything else are lights, bug spots on windshield, reflectors and reflections.
Please re-install Firmware. This will auto-calibrate bright pixels.
I've begun to notice hot pixels once again. What makes a properly calibrated GC with the latest firmware and no hot pixels go out of calibration all of a sudden? Maybe it's the cosmic ray business?
they will change over time which is why the auto calibration is the preferred method where possible as it will keep recalibrating dynamically rather than just using a static value
it's not the nature of Sony sensors, all of these camera sensors do it, the reason it is apparent on the Sony sensors is the auto calibration process in the Novatek SDK initially was not working very well for the Sony sensors so it was elected to use a manual calibration process instead while Novatek were working on improving it
auto calibration doesn't require reinstalling of the firmware, if it has a manual calibration version installed though it's a matter of updating to get that function, updated version will be released soon, will have to wait until later this week though when I'm back in China, I'm in Hong Kong right now and don't have access to what I need to get that sorted
yeah you wouldn't see it in other sensors as the auto calibration was already working well for most popular sensors already, it is something which is easier to see in the Sony also due to larger individual pixel size
The Latest beta firmware should be posted soon with latest optimized auto calibration. (After we are done with the shows in Hong Kong)
It's not obnoxious or bugging the heck out of me - just random specks of a low count, low visibility. I'll just wait until there's a new firmware update that may include a whole spread of tweaks. And scrub the heck out of the windshield in the meantime.Please re-install Firmware. This will auto-calibrate bright pixels.

Think I got some of that stuff around here. Actually it could probably use a good professional polish job.Steel wool #0000 is best. https://www.amazon.com/0000-steel-wool/s?ie=UTF8&page=1&rh=i:aps,k:0000 steel wool
Clean the window as good as you can, then if you have any chrome polish or automotive polish clean and buff the outside of the window and you will be good. Requires some thorough rubbing, but it will be worth the effort. I use Beyond Clay Paint Polish by Surf City Garage and it works great.Think I got some of that stuff around here.

I have to say, until I started playing with dashcams, I've never seen so many hot pixels - and I've handled many different devices in 20 or so years.
Are the dashcam manufacturers using B-grade or rejected sensors?
