display www.texture from url causes crash in some devices

Hi! I need to download an image from a url and display it in a UI.Image component as sprite. I wrote the code below, but it doesn't work in my Samsung Galaxy Tab 3, while it works with a Samsung Galaxy S4 phone. So, why with some devices it works and with others the application crash?

     public void Start () {
         StartCoroutine(RealLoadImage());
     }
         
     private IEnumerator RealLoadImage () {
         string url = "http://www.MY_URL_IMAGE...";
         WWW imageURLWWW = new WWW(url);  
         
         yield return imageURLWWW;        
         
         if(imageURLWWW.texture != null)
         {
             Sprite sprite = new Sprite();     
             sprite = Sprite.Create(imageURLWWW.texture, new Rect(0, 0, imageURLWWW.texture.width, imageURLWWW.texture.height), Vector2.zero);  
             GetComponent<UnityEngine.UI.Image>().sprite = sprite;
         }
         yield return null;
     }
