Texture2D not destroying in Android player

Hi,
I built a system that downloads images from web and store them in the local storage. The game uses a lot of textures and while the player progress I have to delete old textures to make room for new ones.
The way I implemented works fine in Unity Editor, but the Android build is crashing. I look in the profiler and realize that the textures are not been disposed. I'm using Unity 2019.2.12f1.

I create the texture from web like this:

Code (CSharp):

1. UnityWebRequest www = UnityWebRequestTexture.GetTexture(Reference.URL);
2. yield return Timing.WaitUntilDone(www.SendWebRequest());
3. if (www.isNetworkError || www.isHttpError) {
4.     throw new Exception(www.error);
5. } else {
6.     LoadedTexture = ((DownloadHandlerTexture)www.downloadHandler).texture;
7.     LoadedTexture.name = fileName;
8. }

Then I save in the file system. The next time it is requested, it's loaded this way:

Code (CSharp):

1. byte[] fileData = File.ReadAllBytes(FilePath);
2. LoadedTexture = new Texture2D(2, 2);
3. LoadedTexture.name = fileName;
4. LoadedTexture.LoadImage(fileData);
5.  

I have to compress in runtime to decrease the file size:

Code (CSharp):

1. LoadedTexture.Compress(true);

I realize that the asset was related with the scene, so I set the hideFlag to hide and don't save. It changes where the asset is located in Profiler from Scene Assets to Not Saved, but they are also not deleted:

Code (CSharp):

1. LoadedTexture.hideFlags = HideFlags.HideAndDontSave;

The code that I use to delete is:

Code (CSharp):

1. if (LoadedTexture != null) {
2.     UnityEngine.Object.Destroy(LoadedTexture);
3.     LoadedTexture = null;
4. }

The last thing that I tried was to call this functions:

Code (CSharp):

1. Resources.UnloadUnusedAssets();

But it still not releasing memory.

Is it a bug in Unity or am I doing something wrong?

 

I also had that problem. The memory is not really freed on android
