I am a little surprised that you, who have extensive working knowledge about the A119S and have provided videos on such, would advocate using firmware version 1.01 for the A119S instead of the latest firmware V2.2. Is the image quality of V1.01 really so much better as to negate the improvements that have happened since? If you think so, I have to disagree.
Image quality is a very subjective observation. I've observed the complaints and many times been unable to verify complaints by looking at the photos/videos. My old eyes can't see the significant Image Quality differences that some seem to complain about. If the difference cannot be recognized, then it is questionable. If you do see it, then keep complaining. Yes some improvements were false starts, like the XXXXX-Box problem, but all-in-all, there have been pretty impressive improvements from Viofo, including Parking Mode and maybe a real solution to the XXXX-Box problem after encouragement. There has since been only one reported incidence of a similar problem by
@harsh, but without the X-boxes. You don't use Parking Mode with V1.01, because there is none, as Parking Mode wasn't introduced in the A119S until Version 2.1 (maybe a Beta version in V2.0 I think). All in all, I think the A119S image quality is still pretty good in V 2.2 and I will take it over V1.01, considering all the other improvements that have been made.
Parking Mode certainly isn't perfect but was an add-on for the A119 and A119S and a free-bee for users that bought their cameras before the release of the new firmware. Many were happy to have it as the newer high capacity microSD cards were just being proved in dashcams like the A119S at about that time. I have Parking Mode enable all the time. If I choose not to power the camera when parked, I can't tell the difference between Parking Mode and Normal Mode. Improvements between firmware V1.01 and V2.2 include: What
