Rhythm Game - When I touch an object with mobile in only activates 80% of the time...

Hello, -

I am using android. -

I have a rhythm game where notes fall. This script it attached to the notes so that when you touch them on mobile they disappear. It works well but sometimes it doesn't work.. I touch them but they do not go to the blank sprite and I have no idea why..

I have 2 touches registered below as there is sometimes 2 that spawn at ones so you need to touch them both. Without the second section of code it would only let me press one at once.

 void Update()

{

 foreach (Touch touch in Input.touches)
     {
     if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Began)
     {
         touchPosWorld = Camera.main.ScreenToWorldPoint(Input.GetTouch(0).position);
         touchPosWorld2D = new Vector2(touchPosWorld.x, touchPosWorld.y);
         RaycastHit2D hitInformation = Physics2D.Raycast(touchPosWorld2D, Camera.main.transform.forward);

         if (hitInformation.collider.tag != "Button")
         {
             touchedObject = hitInformation.transform.gameObject;
             touchedObject.GetComponent<SpriteRenderer>().sprite = blank;
         }
     }

     if (Input.touchCount > 0 && Input.GetTouch(1).phase == TouchPhase.Began)
     {
         touchPosWorld1 = Camera.main.ScreenToWorldPoint(Input.GetTouch(1).position);
         touchPosWorld2D2 = new Vector2(touchPosWorld1.x, touchPosWorld1.y);
         RaycastHit2D hitInformation2 = Physics2D.Raycast(touchPosWorld2D2, Camera.main.transform.forward);

         if (hitInformation2.collider.tag != "Button")
         {
             touchedObject1 = hitInformation2.transform.gameObject;
             touchedObject1.GetComponent<SpriteRenderer>().sprite = blank;
         }
     }
 }    
 }

I hope you can help.

Thank you very much.
