Video not working with iPhone 5S

[fotiDim]

Video is not working right with iPhone 5s (Romo X app). I do get a video feed but it is very glitchy. I see mostly green frames and only occasionally frames from the camera feed. It seems that the behaviour is dependent on where Romo is facing. On some orientations in my room the camera feed goes normal but as soon as I move Romo a bit it goes green again.

At the same time my iPhone SE works fine, so it must be something with the 5s hardware encoding.
