Google Play Services Login isn't working

Hey,

I implemented the Google Play Services into my Unity Project. But if I want to run on my physical android device, the user hadn't been logged in. I don't know what I'm doing wrong but I'm really desperate now.

This is my code:

 using GooglePlayGames;
 using GooglePlayGames.BasicApi;
 using UnityEngine;
 using UnityEngine.UI;
 
 public class GooglePlayManager : MonoBehaviour {
 
     public Text txtGPSinfo;
     public Button btnSignIn;
 
     // Use this for initialization
     void Start () {
         PlayGamesClientConfiguration config = new PlayGamesClientConfiguration.Builder().Build();
         PlayGamesPlatform.InitializeInstance(config);
         PlayGamesPlatform.Activate();
 
         btnSignIn.onClick.AddListener(delegate
         {
             txtGPSinfo.text = "calling SignIn Method.";
             SignIn();
         });
         
     }
     
     
 
     void SignIn()
     {
         txtGPSinfo.text = "trying to sign in...";         // stucks here: this is the text which is only shown
         Social.localUser.Authenticate(success => {
             txtGPSinfo.text = "success: " + success;
         });
 
         if (Social.localUser.authenticated == true)
         {
             txtGPSinfo.text = "User is already authenticated!";
         }
     }
 
 //...

It looks like it stucks here: Social.localUser.Authenticate(success => { because my info text just shows
