i try do test with normal box and a title room and when i run it on mobile everything was looking smaller not like my game view i don’t know why !

if anyone have any info please share it with me

Often mobile devices have extremely high resolutions for their screen size. If you want it to look the same on your PC as it does on your mobile device you’ll have to run at the same resolution on the PC, or force a specific resolution on the mobile device. By default on your mobile device your game will run at the device’s native resolution.
