I just reliazed the All Call option on Phone - setting - Call to show is missing. I checked on others Note9, the option is available. I found also, many contacts saved on samsung account disappread. Please help.
I don't know about the All Call Option. I've got 2.1 on mine and it's there. As for the other deal about some of your contacts missing. Open the Contact App > 3Dashes Left Side > hit top button and make sure that "All Contacts" is selected.
