I just got a Mate 20 dual sim (upgraded from Mate 9) and i wanted to assign different ringtones for sim1 and sim2 and to assign different ringtones to particular contacts, as well. but none of this is working as the system only takes the default ringtone for all the calls. These things used to work perfectly on my mate 9.
I already factory reset the phone, wipe cache. Please help.
Thanks in advance.
