Hi. The best solution for me is to use the theorem of intersecting lines so that there is neither a cut off on the sides nor a distortion auf the game view. That means that you have to step back or forward in dependency of the different aspect ratio.

If you like, I have an asset on the unity asset store which automatically corrects the camera distance so you never have a distortion or a cut off no matter which handheld device you are using. it is available here:

can someone update the code?

Hello plzzz help me i used this code but it never works on camera i add this script in my main camera ..... Answer me plzzzzz.... @ siddharth3322 is this script need to add only for one camera or every camera in different scenes ???
