So on a few message boards i bragged about not having issues with the new update until yesterdays flight where karma bit my ***, my x4s will not turn on. I still have control of the movement of the camera but I have a black screen. I also had an issue with the perimeter sensors which was beeping as i was bring in towards me, it was notifying it was close to something, me, but it kept drifting towards me until I switched to sport mode and was able to back it up. The reverse control would not work until i switched modes. Anyone else know this issue??? Help with any advise. Be nice if I missed something too.
