After getting the update 4.3 i tried to connect via Kies. When i connected to my Laptop Kies asked to upgrade Kies to 3.0 as Ver 2.6 is not supported by my device. I updated Kies and my S4 i9500 got connected. But now when i tried to connect my Note II an error message appears "the device is not supported by Kies 3.0". Why Samsung cannot think about it? Now i will have to wait till my Note II is upgraded to 4.3. Also same for my S3. Great work Samsung.
