Vv7' s 360 screen shows blue on the left and right cameras.

It depends on whether your screen is blue on one side or one side or all of it. If the whole screen is blue, it's usually because there is something wrong with your 360-degree full-screen control module. If only one side or one side is blue, it is mainly because of the camera. This can be restored by considering the camera on the corresponding side. This may be because of the camera's own filter.
