Unity3D Android Lockscreen does not appear when the screen turns off. (Wakelock?)

Question

I am building an Android app using Unity and it is going very well. However, I have a strange problem with the screen timeout, and the lock screen does not appear.

What is going to happen

• User stops playing
• Screen Timeout and Shutdown
• Later, the player returns and returns his phone to
• Lockscreen indicates whether the user can enter their password or otherwise unlock their phone.
• The application restores focus and continues

What's happening

• User stops playing
• Screen Timeout and Shutdown
• Later, the player returns and returns his phone to
• Lockscreen does NOT show! The application is right in focus, bypassing all screen locks.
• Users go crazy that their security is compromised :(

Unity # script, Java:

public static void InvokeAndroidLockScreen()

    #if UNITY_ANDROID
    using (AndroidJavaClass cls_UnityPlayer = new AndroidJavaClass("com.unity3d.player.UnityPlayer"))
    {
         using (AndroidJavaObject obj_Activity = cls_UnityPlayer.GetStatic<AndroidJavaObject>("currentActivity"))
         {

         }
    }
    #else
    Debug.LogWarning("Cant invoke lockscreen on a non Android Device");
    #endif
