Hi there,

Thank you for performing the battery test.

You've confirmed and provided proof that the root cause of the issue is neither the SD card or a battery issue.
Due to this, it is most likely to be a mechanical sensor issue within the Camera.

The best course of action would be to exchange the Dash Cam with E-Galaxy for a functioning 412GW. However, if you have any issues with this exchange in any kind of way, or they will not accept the exchange, please message me directly and I will be able to provide assistance.

Kind regards,
Millie- Nextbase
