I like using Litchi to fly. I think I found that the front Vision Positioning Sensors do not work or work properly when using Litchi. I can stand directly in front of the Spark when hovering and it does not make a sound or move to avoid me. Does anyone know if the VPS are disabled or do not function correctly when using Litchi to fly the Spark?

I believe that the VPS is the sensor set on the bottom, and used for location and landing, particularly precision landing. The front sensors, above the camera, are used for obstacle avoidance, and can be turned on and off in the DJI Go4 app. It should be similar in the Litchi app.

Thanks for the information. I am aware of the downward facing sensors. I tested yesterday with DJI Go4 app. The front facing sensors emit a loud beep then controller will not move forward. That is the proper function on the sensors. I will do same test today with Litich. I have found I have to delete the GO4 app from my device to get the camera to connect to Litchi. I have not found a simple way to use both apps on my device. I get map and all other features just no camera signal to my mobile device.

You need to force close the Go app via the phone/tablet settings prior to opening up Litchi. No need to remove Go from the device. Assuming your in Android, once opened, a program remains in memory, even though you close it, thus needing to force close the app prior to using Litchi.
