Android touch and drag GUItexture problem

Hi to all. Im new to Unity and Android and im making a race game using guitexture for buttons. When I touch and drag a single gui works fine but when i got two or more guitextures touched at the same time and after this i try to drag one of them (pressing the two guitextures drag my finger out of range of one guitexture) unity do not detect the phase "TouchPhase.Ended". Im looking for some one that know better way to do this or how to fix it. Here is a simple script where I was testing:

 using UnityEngine;
 using System.Collections;
 
 public class touch : MonoBehaviour {
     
     public GUITexture gas;
     public GUITexture breake;
     public GUIText text;
     private int b = 0;
     private int g = 0;
 
     
     void FixedUpdate () {
     
         //print text
         text.text = "gasGUI = " + g + " breakeGUI = " + b;
         //detect touches
         if(Input.touches.Length > 0) {
             for(int i = 0; i < Input.touches.Length; i++) {
                 if (breake.HitTest(Input.touches[i].position)) {
                     if(Input.touches[i].phase == TouchPhase.Stationary) {
                         g = 1;
                     }
                     if (Input.GetTouch(i).phase == TouchPhase.Ended) {
                         g = 0;
                     }
                 }
                 if (gas.HitTest(Input.touches[i].position)) {
                     if(Input.touches[i].phase == TouchPhase.Stationary) {
                         b = 1;
                     }
                     if (Input.GetTouch(i).phase == TouchPhase.Ended) {
                         b = 0;
                     }
                 }
             }
         }
         else if (Input.touches.Length == 0) {
             g = 0;
             b = 0;
         }
     }
 }
