Moving character with touch buttons (Android)

Hello friends I am developing new 2d game. (The game is like a flappy bird but it's just left-right button that goes to itself)

But compared to the problem: the game on the keyboard does not work on touch to the left or right with the arrow keys.

I looked at Har source. Nor are solutions to previous issues. I'm glad you helped me.

 using UnityEngine;
 using System.Collections;
 using UnityEngine.SceneManagement;
 
 public class CharacterControl : MonoBehaviour
 {
 
     // Use this for initialization
     void Start()
     {
 
     }
 
     // Update is called once per frame
     void Update()
     {
 
         float h = Input.GetAxisRaw("Horizontal");
         transform.Translate(new Vector2(h * Time.deltaTime * 5, 0));
 
         
     }
 
     void OnCollisionEnter2D(Collision2D col)
     {
         SceneManager.LoadScene(SceneManager.GetActiveScene().buildIndex);
     }
 }
