Sorry DJI to add to the list of bugs, but here's one I found.
When switching to POV camera and back to gimbal camera, the screen turns dark and flickers. The only way to bring back the gimbal video feed is to return to the DJI Go 4 app main screen, and re-enter the app. (This doesn't happen on my iPhone 7 loaded with the latest DJI Go4 app)

See the video below:

Hi there. I am having the same issue & posted a thread a few days ago regarding it but still heard no fix. a quick workaround rather than having to restart the app is to set a c button to switch between POV & waveform. when it is showing waveform you can switch the pop off and it doesn't cut the feed (in my case) then you can toggle it on again, switch to camera view, switch back to waveform, switch it off. hope that helps but defiantly need a proper fix to this soon.

Hello,

I followed you link but can't find the v02.06.03.00 firmware you referenced in your post.

Do you have a link to it?

Hi CantRepeat, sorry for the late response. The issue has been fixed via the APP update, you may upload the APP to V4.2.20 or later version to see whether it works.

Currently, the APP in CS is available to update seperately, you may go to DJI GO/DJI GO 4 App> "Me"> "Settings" and click "Check for Update", then follow the steps to update to check.
