I have the VAVA 1080P Dual Dashcam. I installed a 64GB microsd card and it worked fine. But after it filled up the camera stopped recording and the solid red LED came on. I attempted to reformat the card, both using the VAVA app and also on my computer. Both claimed the card was reformatted, but it still showed up as full, with all of the old video files still intact. When I then installed in the dashcam the solid red light persisted. I put in a fresh sd card and it worked until it too filled up and the same solid red LED light came on. I am using the latest firmware. How can I really clear all of the up?
