Actually figured it out. Thanks!
How did u figured it out Can u please help us.
Problem :- I am making a Android and IOS Platformer game in landscape mode and i have a problem with the resolutions.
My initial resolution (Viewport size) is 854 x 480 (i.e the Aspect ratio is 16:9). and the layout size is (25,000 X 480, 27500 X 480 and so on..)
I tried many different ways of fullscreen mode and etc. and none seems to work perfectly for all devices.
Please help me to make my project work on all multiple screen size devices (i.e. IphoneX, Ipad, Iphone 5s, Iphone 6, Iphone 6Plus, & all IOS devices & All Size Android Devices).
