1) I use the VIOFO USB cable-cigarette lighter that originally came with my A119 v3 (died) with a mini-USB to USB-C adapter - basically just tagged on the USB-C adapter.
2) I'll check the Boot Delay setting. It seem that the cam always boots up couple seconds after the car is started, at least it seems that the A119M Pro starts a bit slower comparing to my old v3.
3) I have the Samsung Pro Endurance - I don't remember if I changed the bitrate setting from medium to high after watching new firmware bitrate test above. I'll check to be sure.
This has only happened twice, and now I just make sure the cam is up and running before starting to drive. I probably should double-check the card to make sure everything is recorded properly. I'll update in another couple weeks or so. Thank you Chuck.

Thanks for the update.
Well I think we just got it figured out.
If you want to go full bore for the next week or so, try using the CLA Charger & Power Cable that came with A119M Pro.
It’s probably still in the box right?
The #1 & #2 cause of all dash cam malfunctions is;
1.) “Incompatable” SD Card
2.) “Incompatable” Power Supply
The malfunction you report is most likely a combination of;
1.) A119V3 CLA Charger (A119M Pro uses 5V/3.1A) maybe your A119V3 is 5V2.4A
2.) A119V3 Power Cable (A119M Pro uses 20AWG) maybe your A119V3 is 22AWG, or smaller, (it’s written on the cable).
3.) Mini-USB to Type-C Adapter
4.) “Unapproved” Samsung Pro Endurance SD Card.
Just out of curiosity, did you re-use the A119V3 CLA Charger & Power Cable because it was already installed in you car, (power cable tucked behind headliner, A-Pillar trim, under carpet, etc.)?
I learned this the hard way.
When we got the original A119 Mini (IMX335) 2022 it came with 22AWG Power Cable.
After testing that camera, I left the power cable installed, and started testing A139 Pro 3CH.
A119 Mini uses around 3 Watts of power.
A139 Pro 3CH can spike to over 10 Watts of power draw.
That’s when I experienced “power starvation malfunction” for the first time.
I see this happen all the time in Amazon reviews, and in the comment section of YouTube video reviews.
A first time customer buys a Viofo “budget” 1CH dash cam for $100.
After a year, they like it so much they buy a “flagship” 3CH model.
They move the budget 1CH to a second car, and install the flagship 3CH re-using the CLA Charger & Power Cable from the budget 1CH.
They have nothing but problems, blame the brand new 3CH flagship, and say they’ll never buy another Viofo product ever again.
I tried explaining this to Bill in 2022.
I suggested to “standardize” all CLA Chargers & Power Cables with the highest power output, and thickest power wire.
But we have 7 different CLA Chargers & Power Cables currently for sale on the official website.
https://www.viofo.com/collections/charger-cable
1.) D6000
2.) D5000
3.) D3000
4.) D2000
5.) D1500
6.) A119 Mini / A119 Mini 2
7.) VS1
Power cables come in 3 different thickness;
1.) 24AWG
2.) 20AWG
3.) 20AWG
4.) 18AWG (coming soon)
I also suggested including a “small” 64GB VIOFO Brand SD card inside the box of every Viofo Dash Cam, just like BlackVue & Thinkware.
So the customer has a “known good card” to aid troubleshooting when they report a recording malfunction using an unapproved SD Card.
But that melted away faster than an ice cube in you know where. lol
Now with the cost of SD Cards skyrocketing, I bet that will never happen.
Sorry for the rant.
