touch 2d sprite collider

i googled, i looked, i copied, i pasted, but i can not find a solution and i don't know whats wrong!

i have a sprite with a 2d circle collider. i have a game object with a script attached to it

the script contains this code in update

 Touch touch = Input.GetTouch(i);
 Vector2 mousePosition = Camera.main.ScreenToWorldPoint(touch.position);
 Collider2D hit = Physics2D.OverlapPoint(mousePosition);
     
 if (hit != null && hit.tag == "PlayerBuilding") {
   print("ASDFASDF");
 }

when i run it on android, touching the sprite doesn't print my print..

so i then put in this code..

         if(Input.GetMouseButtonDown(0)){
             Vector2 mousePosition = Camera.main.ScreenToWorldPoint(Input.mousePosition);
             Collider2D hitCollider = Physics2D.OverlapPoint(mousePosition);
             if (hitCollider != null && hitCollider.tag == "PlayerBuilding") {
                 print(123);
             }
         }

run it inside unity, mouse clicked my sprite and print works... they are both exactly the same with the exception of one is using mouse position and the other is using touch position.. why doesn't it work????
