Cam is recordong black screen. Video problem Black screen

I got 70mai Smart dash cam pro today. not installed in car yet. just checking the setup but   

it's recording black screen and when i try to open the Video file both in cam and on the Laptop via a card reader. It says the video file is corrupt.

Basically in short term, I think the camera is recording but the image is nor capturing. any suggestions is it a known problem or hardware malfunction?

But i do notice on the first bootup camera worked before installing the SD card. 

I used Sandisk 64GB class 10 brand new memory card for it. later in order to verify it's not a memory card issue. i used 32GB Class 10 card from my cell phone. but still, the issue persists mentioned above.

    1st try to reset device first, 2nd connect with app phone then cek update
    otherwise there is probably hardware failure
