Function well, no compatibility with my S4

Have bought the remote control for my KDL-50W805B.
The remote itself is very good. Fits comfortably in your hand and is very responsive.
The main reason of my purchase, however, was the One Touch NFC connection to the smartphone and there, unfortunately I had to realize that it was not working with my Samsung Galaxy S4.
The device is first detected, there is no connection until he made.
According to the Sony Support the remote control will only work with Sony phones to 100%. For other manufacturers would have to try it.
Therefore, the FB is unfortunately back.
