With the system update from Android 4.4 to Android...

With the system update from Android 4.4 to Android 5.1.1, the technically assured features of the Bluetooth SIM Access Profile (SAP) connectivity disappeared on my S5-mini.
From Samsung Germany I learned by phone in drastic terms that I had bought an "EU device", and that I should contact Samsung Austria.
Samsung-Austria announced by mail: "As of update 5.1, the rSAP profile has been removed from the system by Google. Unfortunately, it is not possible for us to retrofit this function on your Austrian device.
The colleagues in Germany have bypassed this using an app.
For more detailed information, please contact our colleagues in Germany.
You may be able to download them on your Samsung Galaxy S5 Mini. "
(See also my review on Samsung-Austria.)

For the fact that Samsung downgraded technically assured performance features simply by "update?", And leaves the customer in the rain, the one star is already too much.

Samsung itself offers at least one distinctive example of high customer satisfaction and sustainable and efficient customer loyalty.

In order to use my hands-free kit, I can buy a new (different) phone.
Thanks a lot to Sam Sung.
