How to test my microSD card?

You may download h2testw_1.4.zip attached to test the cam.

3. Open h2testw, select your target and choose write+verify.


Note:

It is important to choose a MicroSD card with good quality. We recommend choosing a microSD card with high endurance and UHS-U1/U3 or above class.

Bad-Quality microSD cards have short life endurance and may cause various problems when you use your dashcam. Most of the recording issues are caused by bad-quality microSD cards like randomly stop recording, video corrupted, etc.
