Supporting multiple mobile screen sizes?

I made a game with window and viewport size set to 480X800 and i export it by setting the full screen mode as "Scale Inner". The game works fine in 5.5 inch display but when i test it in 6 inch display, some game elements go outside the screen. i dont know why this is happening. can anyone guide me?
