Firmware 03.21.03, configurator 0.14.5.27701_C.052 or 0.16.1.17313_C.004; it doesn't make a difference. With a freshly rebooted device and no other configuration changes, I go to User Interface and change Outgoing call -> Vibration from Enable to Disable, and then hit Save to device. Result: "Error Failed to save configuration : SETPARAM_RESULT does not match". The same happens if I try to change any other vibration setting.
I'm almost sure that this problem did not exist on FW 03.21.01.
