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 stopped recording, video corrupted, etc.
