Its my first time asking so I hope its the right place
I am trying to make a game by using cocoonjs for android but I got serious problems about its screen scaling. I made my layouts 640px x 480 px and used fullscreen scale mode but its doesnt scale it for my Samsung Galaxy S Advance. Its screen size is 800px x 480px and when I import the game, a lot of gap appears. I searched through the forum and read all the tutorials but I dont want to strech or make my sprites bigger because there are pretty lot of them.
Also, I got another problem with layout transition. During the transition, the layout doesnt smoothly takes the place of the last one. It shakes and a little bit of whiteness appear for a sec then the other layout comes in. I checked everything but nothing seems wrong.
I would really appreciate if you can help me
