Problem 2: APP video file is empty, no video is loaded. Solution: 1.Please open the App settings to format the memory card and then record the video. 2.If the App album still has no video, please insert the memory card into a computer, check whether the memory card is damaged, or not compatible with the camera, if so you need to replace the memory card. 3.It is recommended to use Class10 specification SanDisk/KIOXIA/Samsung memory cards of 32GB or 64GB capacity. (Maximum size supported is 128GB) Problem 3: Why doesn't my computer play the videos? Or why is the playback video not smooth? Solution: 1.We recommend the use of PotPlayer and KMplayer players. 2.If the computer configuration is too low, it may cause the playback to not be smooth, especially for 4K resolution videos. Problem 4: Why can't you connect 2 phones at the same time? Solution: WiFi only supports connecting one phone at the same time; if another phone needs to be connected, you must first disconnect the WiFi of the first phone. Problem 5: Why is the timestamp of the video wrong, or there is no recorded video during some time periods, or there is video when the phone is connected, but no video when the phone is not connected? Solution: Please check if the timestamp error is caused by a complete power failure of the camera. After car repair, maintenance or battery replacement, you need to reconnect the camera's WiFi with your phone to synchronize the camera's time with your phone's time. Please regularly check that the camera is working properly. Problem 6: What should I do if I forget the WiFi name or password? Solution: Press and hold the camera key for 20 seconds, or use a paperclip to press the reset button. Problem 7: Do I need to connect the camera WiFi and open the App every time I drive? Solution: No need, the camera is automatically turned on and off. The camera will automatically turn on when the car is on and turn off when the car is off. Problem 8: What should I do if I can't find the WiFi? Solution: 1.First, remove the memory card and then search for WiFi, because memory card failure will cause the camera to have no WiFi. 2.Press and hold the camera button for 20 seconds, or use a paper clip to press the reset button. Restore factory settings. 3. Check whether the camera's light is always on. If there is no light, it means there is no power supply, then there will be no WiFi.
