Customizable screen buttons

I don’t know why this never occurred to me as an idea before, but it would be really awesome if we could customize the layout of the screen buttons for in-game play. I’ve always been a galaxy s# owner and player, my s7 edge had the arrows in the bottom left away from the corner and a little bigger. My friend has always had iphones and his buttons were smaller and close to the corner, it was pretty difficult for me to play on this setup. My newer phone, a galaxy s8, has the buttons in the corner and small like the iphone setup I had played on. If I had the option to go in and manually move and resize the buttons that would make the game a LOT more comfortable and player friendly across all devices as you could set it up the way that feels most comfortable per user.
