I read document about the UIRoot component and I found:
Scaling Style: The following are the available scaling styles:
° PixelPerfect: This will ensure that your UI will always try to remain at the same size in pixels, no matter what resolution. In this scaling mode, a 300 x 200 window will be huge on a 320 x 240 screen and tiny on a 1920 x 1080 screen. That also means that if you have a smaller resolution than your UI, it will be cropped.
° FixedSize: This will ensure that your UI will be proportionally resized depending on the screen's height. The result is that your UI will not be pixel perfect but will scale to fit the current screen size.
° FixedSizeOnMobiles: This will ensure fixed size on mobiles and pixel perfect everywhere else.
and I'm using FixedSizeOnMobiles with Manual Height: 720. Minimum Height: 320. But when app run in tablet, all button, background,.... it look not good!
What shoud I do?
