It looks like one of my DR970X Plus' is toast. The one I'm running up front power cycles regularly while driving and most of the footage has these pink lines that keep scrolling through the now very jerky footage.

This happens both when driving or when parked, with both firmware 1.000 and 1.001 (which has since been pulled from Blackvue's site for some reason), and regardless of memory card (including several Blackvue cards). The dashcam is basically unusable and needs to be replaced. This was my sharper copy of the two and hopefully the replacement unit has an in focus lens.
At this point I'm feeling pretty frustrated with these dashcams. They have consistent lens focus issues for both the front and rear cams, exposure flickering issues, reliability issues, periodic security vulnerabilities for the cloud features, I can sometimes connect to my dashcams with my iPhone but not my Android, Blackvue has removed some features that I really liked on previous models including the ability to connect to multiple hotspots and to have fine tuned control over voice notifications, etc.
I've run Blackvues as my primary dashcam for about a decade now, but given the issues that I and others have been reporting with these latest models, I don't think I can justify recommending it any longer given the high pricepoint and compromised video quality and reliability. Cloud stuff is great, but you gotta nail the basics.
