Issue Descriptions
After the app enters the camera view or during flight, the app may prompt “No image transmission signal,” or the image transmission screen turns black.
Cause 1: Incompatible Firmware
The app version is not supported by the device firmware version. For example, the remote controller firmware previously installed is not supported by the aircraft.
Solution
After updating the firmware of the aircraft and remote controller to the latest version using the latest DJI GO 4 or DJI Fly app, check if this issue is fixed.
Cause 2: Signal Interference
The image transmission is easily affected by signal interference, such as . For example, radio signals.
Solution
First, check the current channel status in the app.
