Dash cam observation

For the sleuths out there, we are used to our Vantrue. No complaints, true 4K, older Starvis sensor, have a front/rear setup in my daily driver that is off the road right now.

Flash forward when our vehicle was destroyed in May 2025, another Vantrue was destroyed.

When we got a replacement vehicle, got the ROVE which is super popular, newer 4k sensor, and nice price $99 with front and rear 1080, never installed rear.

Everything was happening similar to the Vantrue.

One day I go to pull video, and nothing is there. Nice. Improbable. Windows says card is full.

I did trick #1 look for a protected folder, empty. Look for hidden files, none.

Baffled and seeming to read complaints, I broke down and spent 2X on their proprietary micro SD card. But in doing all of this, I decided to install the smartphone app and read the dash cam.

ALL OF THE VIDEOS ARE SEEN BY THE APP!

What's going on? lol

I mean seriously, in my mind the idea is there is usually 256 gb of useless 3 min videos. But if something is noteworthy, I want to pop the micro SD, and upload to my laptop. In this scenario, my laptop can't see anything. But it's there, since the Rove app sees all, and Windows did recognize the micro sd is full (constant rewrite).

Again, with the Vanture, everything works as I expect it to. The Rove, no. I don't want to download videos onto the smartphone. I haven't the space.

Whaddya all think? thx!

p.s. let me add this info....mid year yes, my laptop did see all the ROVE videos on the micro SD. So this is a newer development, but it is confirmed to repeat, even upon reformatting of the micro sd card. my hunch is people out there did report similar and the answer was to buy their own proprietary card
