Cant find where the screenshots are saved or if they are even taken

heres the script

 using UnityEngine;
 using System.Collections;
 using UnityEngine.SceneManagement;
 using System.IO;
 
 public class scene2 : MonoBehaviour
 {
 
     
     private int Screen_Shot_Count = 0;
     private bool Shot_Taken = false;
     private string screenshot;
 
 
     WebCamTexture webcamTexture = new WebCamTexture(); // Plane gets camera texture
 
     public GameObject plane;
     public Texture2D back;
     public int activeButton = 1;
 
     void Start()
     {
         Renderer renderer = plane.GetComponent<Renderer>();
         renderer.material.mainTexture = webcamTexture;
 
         plane.SetActive(false);
     }
     void Update()
     {
 
     }
     void OnGUI()
     {
         if (activeButton == 1)
         {
             if (GUI.Button(new Rect(0, 740, 60, 60), back))
             {
                 SceneManager.LoadScene(0);
             }
             if (GUI.Button(new Rect(420, 740, 60, 60), "camera"))
             {
                 plane.SetActive(true);
                 activeButton = 2;
                 {
                     webcamTexture.Play();
                 }
             }
         }
         if (activeButton == 2)
         {
             if (GUI.Button(new Rect(420, 740, 60, 60), "atgal")) //back button when camera is active
             {
                 webcamTexture.Stop();
                 activeButton = 1;
                 {
                     plane.SetActive(false);
                 }
 
             }
             if (GUI.Button(new Rect(420, 360, 60, 60), "photo"))
             {
                 Screen_Shot_Count++;
                 screenshot = "Screenshot__" + Screen_Shot_Count + System.DateTime.Now.ToString("__yyyy-MM-dd") + ".png";
                 Application.CaptureScreenshot(screenshot);
                 Shot_Taken = true;
                 Debug.LogError("works123"); //works on pc
             }
 
             if (Shot_Taken == true)
             {
                 string Origin_Path = System.IO.Path.Combine(Application.persistentDataPath, screenshot);
                 // This is the path of my folder.
                 string Path = "/storage/emulated/0/Calculator/" + screenshot;
                 
                 if (File.Exists(Origin_Path))
                 {
                     File.Move(Origin_Path, Path);
                     Shot_Taken = false;
                 }
             }
         }
     }
 }

everything seem to work ,even when i press ''photo'' button to take screenshot, it lags for half a second as if it was taking screenshot ,but it just doesnt appear anywhere.Maybe someone know what might be the problem? i am also using plane to render live input from camera. heres 2 pictures so maybe its easier to imagine what this script looks like: http://imgur.com/a/YaDsz ,i used this post as an example http://answers.unity3d.com/questions/845836/saving-path-for-screenshot.html
