Mute Incoming Call By Turning The Phone Doenst Work On Mi4c ( Stable Version )

[kekol]

Hi to all,

i received my Mi4c yesterday.
I just flashed the stable version 7.1.6.0 and also tried 7.2.1.0 but muting a incoming call by turning the phone doesnt work.
Phone->settings->settings for incoming calls->turn to mute ( enabled )
Any solution? or flash the weekly rom?

Thanks
