While flying, i just recently started having problems with the apps video feed lagging, and glitching/pixelating. This is all while still very close to the drone, all background apps closed, phone in airplane mode etc. It happens in different locations, so its not interference in one spot. i have a full hd and controller signal to the drone when it happens. The drone responds flawlessly to me controlling it, the problem seems to be the app itself. This is getting very irritating. What can I do?
