Why are random contacts disappearing?
Today at lunch I called someone in my contacts list. I looked up their number and called them from the data I had stored.
This evening I went to call them again, and their name wasn't in my recent calls. When I searched contacts again, they weren't in my contacts. Neither was their husband's number. Their numbers were in recent calls, not their names.
Then later tonight I went to call my wife from my favourites list and she and 3 others have had their names disappear. Their numbers are in my favourites list, but they too have disappeared from my contacts.
All of these people have been in my contacts for months or years.
I do have 10 other favourites who are in my favourites, and 1200 other contacts in my contacts list, but for some reason, today, I've begun to lose people at random.
Anyone have the same, or know a solution?
