Regarding the smaller screen: Its exactly as big as before (Samsung S8). now the edge just matches the color of the edge of the screen, before the update it was just black, i can remember because thats where the Zoom factor is on the left side, its made more optically pleasing.
About RTH: I can confirm that i didnt see the RTH hight and some other options on my android phone as well, until i was actually connected to the powered on drone.
I am quite happy with this update. it might be my imagination but i believe the live video got more stable as well.
