I have an Android device and like a lot of other people, with the June firmware update djo go 4 now has extremely low video and lots of lag. Now if you want to have quality flight time you have three options. Buy an iOS device, ir use a different software, I would choose the latter. Now if you try a different software, you could buy litchi for 30 dollars, or you could get AIRNAP, which not only allows you to fly your drone, but also provides a live airspace map, and automatic wavers and authorization.
