Still testing.
I'm not sure this is a new bug or it's related to other similar bugs.
Start my car engine, Viofo A119 REC light is on AND Viofo is not recording at all. No beeps, display off, no blinking leds. This is a serious bug: any user thinks Viofo is recording but it isn't.
How you could reproduce it (maybe).
1. Set loop interval to off
2. Format SD
3. Start recording
4. Wait until SD is full, then Viofo will stop recording and start beeping
5. Press menu button to stop beeping
6. Power off the car (and so Viofo)
7. Power on the car (and so Viofo)
8. Look at Viofo: now REC button light is on, display auto power off after few seconds (as usual), no blinking leds and no beeps. BUT Viofo is not recording. If you press menu: display power on and you will see no red circle icon in the header bar
Maybe I disable format warnings, but this is not the point. In my opinion, REC button should never be on when Viofo is not recording. And when Viofo is not recording you should every time listen a loud beep (user can stop it pressing menu, but beep must restart when user restart his car).
Notes:
1. I know you says never set loop interval to off (and I agree with you) BUT if Viofo gives this option we should test it over and over
2. I still don't understand why loop interval off doesn't delete old files. It's a fat32 format, so files can't be bigger than 4gb. With modern huge sd card old files could/should be deleted with no hassle (as when you set 10 min time interval)
