Is the video recording divided into 3-minute clips? Why there are video clips less than 3 minutes (images missing between different clips)?
The problem is caused by manual settings on YI Smart Dashcam when the camera is in use. For example, pausing the video, watching the video replay or changing settings on the camera without the APP connection would pause the recording process, producing clips less than 3 minutes. Besides, when the camera is connected to the APP, viewing the album or setting the camera in the APP would also cause the problem. Also, the reading/writing speed of your microMicroSD card influence the quality of the recording. It is advised that you format the microMicroSD card or replace it by a new Class 10 80MB/s read speed microMicroSD card to see if this problem is solved.
