How do I switch shooting modes or set the camera?

To change the shooting mode or settings, press and hold the WiFi(Up) button for 2-3 seconds for easy switching. It takes a little more patience than the touchscreen. But after using the action camera for a while, you will get used to its operation.

The camera doesn't stay connected to the phone APP. How can I fix this problem?

I recommend that you turn off cellular data on your phone and then connect to the camera via WiFi. This will ensure that the WiFi connection is not affected by the phone's network and will improve the stability of the WiFi connection.

The SJ4000 action camera is inserted a micro SD card(TF card), but it still prompting "Please insert SD card".
