It seems its absoultely crazy question but really i cannot find answer: after update my phone to android 6, it seems in the call forwarding setting is missed in setting menu! i also search it using filed button but i cannot find it, could anyone help me about the situation in this version? i have Huawi P8Lite. Thanks a lot.
Look in the Dialer/Phone app settings itself to see if the option is there. On my S7 Edge the option is there, but that Dialer/Phone app is most likely different from Huawi's.
