Screean gamr shrink

I new to this.I just test platformer tamplate and camera just shrink. It show player and just 1 button. I can’t see well in front of player. I have same problem with my new project. I set resolution to mobile and after i tes play. It show upper left from scene screen. Is there any solution to this like scroll my screen or something. Thanks

You flip your phone? And also, use PC if you have one. Its easier.

No flip. Just lock in portrait screen.
I agree with pc. But due to some reason i mainly use phone for now
