ANDROID TOUCH look around with camera

What is up!

So I looked around for some questions in answers.Unity and it seems no one has asked this question. I highlighted within the code of me using the Quaternion.Vector3 method to rotate the camera when a person move their fingers on the touch screen.

My problem is the object direction as you can see it returns x and y values but both are changing, i.e. when you move your finger across the screen, x and y values changes dramatically

So when I try to rotate on the x axis the camera rotates at an angle while moving y axis as you can see this is way too CHOPPY for a First Person shooter.

Any advice?

Thank you in Advance, Sixbreaker

 if (Input.touchCount > 0) {
         var touch: Touch = Input.GetTouch(0);
         // Handle finger movements based on touch phase.
         switch (touch.phase) {
             // Record initial touch position.
             case TouchPhase.Began:
 
                 startPos = touch.position;
                 directionChosen = false;
                     
                 break;
                 // Determine direction by comparing the current touch position with the initial one.
             case TouchPhase.Moved:
             
                 
                 //the following code for rotation via Y.
                 direction = touch.position - startPos;
                 yAxis = maincam.transform.localRotation.y;
              
                 **if (direction.y > 0) {
                     maincam.transform.localRotation = Quaternion.Euler(Vector3(0, n++, 0));
                     }
                 else if (direction.y < 0) {
                     maincam.transform.localRotation = Quaternion.Euler(Vector3(0, n--, 0));
                 }
 
                 if ((n > 360) || (n < -360))
                     n = 0;**
 
                 
 
                 break;
                 // Report that a direction has been chosen when the finger is lifted.
             case TouchPhase.Ended:
                 directionChosen = true;
               //  n = 0;
               //  neg = 0;
                 break;
         }
