Game design is scaled when exporting to iOS/Android

Hi,

I am new to unity and trying to build a simple game. When I work on unity Editor it seems to work fine.

Say in unity I am checking with dimension 750x1334:



And in phone it looks different - iphone7 - 750*1334




I tried so many solutions like setting the screen.setresolution, camera.aspectRation, etc but not fixed this issue. can anyone please help me ?
