Can I choose Classic UI?

I updated my Infinite Flight to new version, and new UI which HDG,SPD…etc) moved to right side is inconvenient for me. Can I select Classic UI which HDG, SPD and Throttle is at left side?

p.s. I’m using Galaxy S4+ which use snapdragon 800, When I update infinite flight, it’s frame drops a lot. Is this App’s problem?

No, you cannot, the positioning of those are based on your screen size, something has changed since the last update to change some of those.
