Destroying Android and adding power

Question

I am working on a 2D endless runner. I have the code below to enter screen input to jump, slide and run fast. I provide jumpHeight from the editor, and the value is 500 with a frame rate of 30. The code works fine, but sometimes the player jumps too high for a swipe. Similar code works as expected if input from the keyboard. Why is this happening outside my understanding of unity. Any help is appreciated.

using UnityEngine;
public class PlayerControl : MonoBehaviour
{

    public float ForwardSpeed = 3.7f; //moves player in forward direction
    public float speedOffset = 0.0f; //offset speed of player
    public float JumpHeight = 250; //moves player in verticle direction
    bool grounded = false; //checks if player is grounded or not
    public Transform groundCheck;
    float groundCheckRadius = 0.3f; //radius of groundcheck circle to check grounded bool
    public LayerMask groundLayer;
    Vector2 fingerStart;
    Vector2 fingerEnd;

    void Update()
    {
        foreach (Touch touch in Input.touches)
        {
            if (touch.phase == TouchPhase.Began)
            {
                fingerStart = touch.position;
                fingerEnd = touch.position;
            }

            if (touch.phase == TouchPhase.Moved)
            {
                fingerEnd = touch.position;
                if (Mathf.Abs(fingerEnd.y - fingerStart.y) > 50)//Vertical swipe
                {
                    if (fingerEnd.y - fingerStart.y > 50)//up swipe
                    {
                        Jump();
                    }
                    else if (fingerEnd.y - fingerStart.y < -50)//Down swipe

        //check if circle overlaps with ground layer
        grounded = Physics2D.OverlapCircle(groundCheck.position, groundCheckRadius, groundLayer);

You have 2 problems with your code.

Your first problem is this line of code:

 grounded = Physics2D.OverlapCircle(groundCheck.position, groundCheckRadius, groundLayer);

. grounded true. - , .

 Collider2D playerCollider = gameObject.GetComponent<Collider2D>();
 grounded = Physics2D.OverlapCircle(playerCollider.transform.position, 1, groundLayer); 

Collider2D playerCollider = gameObject.GetComponent<Collider2D>();
grounded = playerCollider.IsTouchingLayers(groundLayer.value);

- false. true, false. LateUpdate, .

, . 0 0,5, . , , . .5 to 1 - . Time.deltaTime. .
