Gravity speed slows down when increasing screen size

Hello guys!
I’m working on 2D mobile game and my player is falling slower when i increase screen size in unity editor, also same thing happens on different sized phones - bigger phone screen size, slower falling speed. why is this happening?

You need a screen independent gravity. Gravity doesn’t change actually. what changes is the height when your screen gets taller. You need something like:

float designScreenHeight = 960f; // design screen height. change this to your value
void OnAwake()
{
    Physics2D.gravity = new Vector2(0, -9.8.0f) * Screen.height / designScreenHeight;
}

Hope that is helpful.
