Nexus 2X (N2X) Dash Cam Review LN

[LateralNW]

Swap the MicroSD card to another Vantrue one if available and then repeat testing. See if you encounter any issues. This would be the first step to troubleshoot. If the issue goes away, you've narrowed it down to the SD Card. If the issue persists, then it is either a faulty 12V adapter or the camera may be faulty.

Note: Should you not have a spare Vantrue MicroSD, run Sd Card Formatter and do an overwrite format on existing card.

Please follow these steps and report back your results.

Thanks for your suggestions but I think you have missed the most important part, and that is the files are damaged and need to be repaired otherwise the hours of the trip are lost.

Regarding your suggestions do you realise that the memory card recorded the internal videos without a hitch as I mentioned above? It would be weird that the card is selective in the files it is saving correctly.
I think the sensor or the bits that manage it went a little haywire.

As a user I they would prefer that the files are fixed than to play around with SD-cards, power etc.

If you have a suggestion on how to repair the files I'm all ears. I do have a few ideas up my sleeve that I am going to try.

This was a one off trip and I expected the Vantrue N2X just to do it in its sleep so to speak.
My intention was to make a video about the trip on my YouTube channel with glowing praise. I won't be doing that now.

Regardless of the brand, reliability while recording is expected to be the highest priority.

Nothing you can do. The files are damaged. Recovery software isn't going to repair a corrupted / faulty memory card in this case. It's unlikely the controller card is damaged, as the card is still readable. Even if that were the case, pulling data off a damaged MicroSD requires soldering leads to the actual card to read from the memory directly. Chances are, since the card is likely the issue, the data wasn't written to the card to be "recovered" in the first place.

Well as I said above, firmware bug (you're up to date and no one else has an issue), bad 12V adapter providing intermittent power leading to erratic behavior, or a MicroSD card unable to write at the proper data stream due to bad controller card / not formatted in a while.

Ultimately, if you swap MicoSD cards to a different one and the behavior continues, you'd need to test another 12V Adapter. If the behavior persists, the camera is bad.

As a user I they would prefer that the files are fixed than to play around with SD-cards, power etc.

While possible, the camera is less likely to be the culprit than the MicroSD or Bad Power Adapter. It's possible, but all signs point to a faulty MicroSD or 12V Adapter.....

Per the above, if the data wasn't written, how exactly do you expect to recover the files? Recovery software can only read what was either deleted or overwritten. It's not going to fill in the blanks on your missing / corrupted footage.

Again, if the controller card were bad on the MicroSD and you are having issues pulling off data, the above soldering method COULD WORK but very very unlikely. The card itself can be read and data pulled off.

You have misunderstood what happened.
I never said there where no files.
I have the entire trip from the front camera but the video format seems to be damaged.

And again as i said previously every cabin video is on the memory card, so the memory card is less likely to be the reason.

It's a glitch in the matrix that Neo couldn't fix.

I suggest you try to create an image of the MicroSD card. Download Macrium Reflect and image the entire card. Instead of playing with card itself and risking further corruption, play with the image.

Unless what you uploaded is not representative of the actual problem, your video shows skipping as if the memory card didn't record and then began recording again? Or what exactly have you lost.

Maybe better explain things and I'll try to assist.

Something I just noticed today while trying to recover the videos is the Vantrue Logo is intact in the recorded video.
There an no lines in it.
Given it is an overlay I think it would be fair to assume that if the memory card is slow then it would have also put lines through the logo.
The text at the bottom of the screen is also fine.

This might be a sign what is happening. The video is damaged before the overlay is added and then all of it is saved to the memory card.

Perhaps after 4 hours of continuous use at 15degrees C the internals got hot! IDK

I think this discounts the idea the memory card is corrupted.

This also most likely means I won't be able to recover the correct video as it never recorded it correctly.

I'll share my findings with Vantrue as an observation and not a request to resolve. I'll leave that up to Vantrue.

Thanks to all for their input.

So there's no gap in the video recorded? The issue is white lines going through the entirety of the recorded videos? 15C isn't that hot at all. The MicroSD card shouldn't corrupt at that low of heat.

Not sure how well this would work on video as corrupted as yours, but worth a shot.

Google also showed this as a possibility: No clue from experience

STEPS:
1. Go to invideo.io
2. Click Trends → See All → VFX House
3. Open the Inpaint & Cleanup tool
4. Upload your video
5. Type a prompt like: “remove background people, keep main subject”
6. Match your aspect ratio (9:16 or 16:9)
7. Click generate and you’re done

Replace the MicroSD card. Guessing it's faulty.

Hi,

First, please confirm whether your N2X has been updated to the latest firmware version. I recommend updating the firmware to see if the issue can be resolved or improved.

At the same time, please also check whether there may be any abnormalities with the power supply during use, especially since the unit was connected to constant power for an extended period.

If you notice any other issues or changes, please feel free to keep me updated.

I've done further testing and believe the problem happens when the Nexus2X is goes into looping.

I tested this with a different industrial sdcard and power supply.

The cabin video is fine.
The front camera videos have missing horizontal lines.

When I originally tested this unit it was fine.
I wonder if the latest firmware update may be the cause?

If this were the case on firmware, flash back to an older version, and see if the issue persists.

You simply need to have Vantrue send you a prior revision or locate it online. Then place into the root folder of the MicroSD card.

It's very unlikely a firmware issue though.
