I\'m using SignaturePad with Xamarin.Forms and it works fine even on basic hardware devices, but I\'ve struggled with a weird behavior with just one device: Samsung

    I've implemented the SignaturePadView in the following way.

    MainActivity.cs:

    protected override void OnCreate(Bundle savedInstanceState)
    {
        base.OnCreate(savedInstanceState);
        // Set our view from the "main" layout resource
        SetContentView(Resource.Layout.Main);
    
        Xamarin.Forms.Forms.Init(this.ApplicationContext, savedInstanceState);
    
        signatureView = new SignaturePadView(this);
        signatureView.StrokeWidth = 4;
    
        LinearLayout signatureLayout = (LinearLayout)FindViewById(Resource.Id.signatureLayout);
        signatureLayout.AddView(signatureView);
    
        Button btnSave = FindViewById

    Here is the layout in my Main.axml:

    
        
    

    I just have a hunch that you are creating a new SignaturePadView object or adding it to the layout after some event happens by the user.
