@jokiin I'm wondering is there's a combination of causes bringing the file corruption. I know power loss to the processor such as bad caps or LiPo can do this, but could a FW bug be involved if the cam shuts down properly on button-press but not on power loss?
There are some cases of apparently loose out-of-spec MMCX coax connectors for the secondary cams. I can understand that causing issues but it shouldn't relate to file corruption on shutdown when there's no movement involved. Or could it?
Presumably this cam is selling at a normal rate, yet we're getting only a very few who are reporting issues that aren't apparently FW caused or related to the loose coax connectors. It may be exacerbated by higher heats, yet it's been seen to occur at lower heat levels which are not normally a problem. I'd suspect a bad solder joint but with the way this is done just about eliminates that possibility. About all that's left is some bad components in some cams, or am I missing something?
Definitely one of the hardest things to diagnose which I've seen in my half-decade of dashcamming.
