Black screen on Mini 3 during mission on Android

Hello,

First of all, I would like to thank the Litchi team for the great app you are working on. It will indeed bring many new possibilities to drones like mine, the Mini 3. Congratulations on your dedication and efforts!

This is what happened to me:

Yesterday, when I was performing a mission in grid mode, the camera view simply disappeared, the screen went black. The map view with the icon of the drone completing the mission was ok, working in real time, but no images. In fact, randomly and very rarely, you could say that a frame was loaded, but then it disappeared.

When I switched to the camera view, at least to check if the camera settings were good, at one point, my flight was paused in the app because it froze so badly that I thought I was going to close the app, actually.

On October 19th of last year, I last flew the app and everything worked perfectly, which indicates that the problem was with the update of one of the versions since then.

As for the images captured, everything is fine.

My drone is a Mini 3, using the screenless controller on a Galaxy S20 FE (SM-G780G/DS) smartphone, Android 13, One UI version 5.1.

If you need more information, I am at your disposal.

Thank you!

It is strange that it was working and then stopped. Normally this would mean that your signal quality was not good, but that may not be the case here. If DJI Fly is running in the background, that can also interfere with your video feed. Make sure that DJI Fly is “force closed” before running the Litchi Pilot app.

I have also seen one other case were someone was having a similar problem with the latest version of the Litchi Pilot app.

Hello,

Yes, I always check if DJI Fly is really closed because otherwise my drone won’t even connect to Litchi. In fact, if I want to switch from one app to another, I need to disconnect the cable that connects the controller to the phone and connect it again. It’s as if the smartphone only connects to one of them at a time.

These “blackouts” happen even when the drone is literally right next to me. It’s something intermittent, but it shows the black screen more than the image itself. I would say that 99% of the time I used it yesterday I didn’t see the image on the screen, just trusting the “instrument flight”. In fact, when I needed to return with the drone to change batteries, I did so just based on the map.

I did my flight twice, also to ensure images at 90 and 45 degrees of camera tilt. Right after finishing the second one, I went through the whole process to access the drone again through DJI Fly and everything worked normally in the native app.

I tried to do some tests to see if it would solve the problem, including turning the augmented reality option on and off, but I was unsuccessful.

We are investigating this issue, but it looks like the Mini 3 video transmission issue is a bug from the latest DJI SDK version and if that’s the case then we will need to wait for DJI to fix it. In the meantime, you can download the previous Litchi Pilot build by clicking here
