Dim ftp As FTP
    ftp.Initialize("FTP", "IP", 21, USER", "PASSWORD")
    ftp.PassiveMode = True
    If ftp.IsInitialized=True Then
        Log("OK FTP!") '
    End If

I am uploading an image from my server / host and saving it in my smartphone

My suspect was right
Use (from FTP)
DownloadFile (ServerFilePath As String, AsciiFile As Boolean, DeviceFolder As String, DeviceFile As String) As Object
You have events DownloadProgress and DownloadCompleted

In addition to what @udg said i suggest to get familar with the terms and how FTP works.

Your App is using the FTP-Client.
So getting anything from the FTP-Server is a DOWNLOAD.
Putting something into the FTP Server is a UPLOAD.

There is no such thing like "the server send anything". The Client REQUEST something and then the server sends the file.
But it is the CLIENT who tell the server to send something.

Download and Upload does have different Parameters. And for sure different meanings.

as I can see I have to remove all permissions on my application and the "RuntimePermissions" library
