Now my game is currently use 3:4 aspect ratio ,which is 480*640 , so my game has the letterbox (I don't like stretch) on my android mobile and my friend mobile. I don't like letterbox, so I have just change color of my letter box to the color that blend with my game background, but I don't like it either. So now I think about change aspect ratio and screen resolution of my game.
how about 480x800 ?
