Hi Guys,
I am having these green and red patterns as soon as I switch to video mode in the dji go app.
I am using a Phantom 3 Advanced together with a Samsung 3GS.
Photomode is working fine, the patterns only appear in video Mode.
Also, when I record the video that comes out is fine, too, so it should be a problem with the app.
Hope you guys can help me!
Need to fly tomorrow.

I don't think your device has the processing power to make the GO app work correctly. You can also try to lower the "Video Transmission Quality" in the HS settings tab.
