Touch camera movement isn't smooth on Android

Hey!

I got the following code that is supposed to move the camera up and down in my game:

 using UnityEngine;
 using System.Collections;
 
 public class TouchControl : MonoBehaviour {
     public float speed = 0.5F;
     void Update() {
         if (Input.touchCount > 0 && Input.GetTouch(0).phase == TouchPhase.Moved) {
             // Get movement of the finger since last frame
             Vector2 touchDeltaPosition = Input.GetTouch(0).deltaPosition;
 
             // Move object across XY plane
             transform.Translate(0, -touchDeltaPosition.y * speed, 0);
         }
     }
 }

The code works fine but on my phone it's not smooth at all when swiping up and down, does someone have any idea how I can fix this?
