2 years ago i bought a yi dashcam from here. This few weeks, my dashcam got some issue, it always say memory card got problem.. i thought the memory card that i bought together with the dashcam from the seller has issue and i go to digital mall to get a new one.

Once i insert the card into the dashcam, it work for sometimes but same error message that I get before this pops up again. May I know what is the issue? Is my dashcam malfunction already?
