Unity2d android detecting touches

How to detect touches and long touches on buttons in unity for android? I have already tried this function but it returns true if i touch any place on screen:

bool checkTouch()
    {
        for(int i = 0; i < Input.touchCount; i++)
        {
            TouchPhase tp = Input.GetTouch(i).phase;
          if(tp == TouchPhase.Began || tp == TouchPhase.Ended || tp == TouchPhase.Stationary)
            return true;  
        }
        return false;
    }

One way to achieve Buttons that allow that, is to create your own button, implementing the necessary interfaces like IPointerDownHandler, IPointerUpHandler.

That way you could manage how will the button act, here is an example:

using UnityEngine;
using UnityEngine.EventSystems;

public class LongClickButton : MonoBehaviour, IPointerDownHandler, IPointerUpHandler
{
    private bool pointerDown;
    private float pointerDownTimer;

    [SerializeField]
    private float requiredHoldTime;    

    public void OnPointerDown(PointerEventData eventData)
    {
        pointerDown = true;
        Debug.Log("OnPointerDown");
    }

    public void OnPointerUp(PointerEventData eventData)
    {
        Reset();
        Debug.Log("OnPointerUp");
    }

    private void Update()
    {
        if (pointerDown)
        {
            pointerDownTimer += Time.deltaTime;
            if (pointerDownTimer >= requiredHoldTime)
            {
                //do your LongClick stuff
                Debug.Log("LongClick");
                Reset();
            }
        }
    }

    private void Reset()
    {
        pointerDown = false;
        pointerDownTimer = 0;
    }    
}

Remember to attach the script to a GameObject that can be interactable, like an Image.
