I updated with the recent iOS update and I checked if my carrier had an update and they do not currently. Initially it seemed to be doing better at first. Then out of the blue yesterday it started showing numbers only instead of contacts, where as the day before it was doing fine with certain contacts. After dealing with this for close to a month I have noticed a couple of things...
- I have two sets of contacts in my phone - Google and iCloud. Some are duplicates, but this has never been a problem before.
- how the phone number is listed may determine whether the my phone shows the contact name. Example, at first the phone didnt show the contact name if the phone number was listed as XXXXXXXXXX or (XXX) XXX-XXXX it had to be listed in the contact as +1 (XXX) XXX-XXXX, but the only way to get the number to be formatted that way is if I ADDED the number to the contact. I couldn't simply edit the contact number to that format. But once I started working on updating my contacts to this format a couple of days latter it reverted back to where the phone seemed to want the number in another format with no area code parenthesis.
- Most recent new things is what user below mentioned about showing in group messages where I reply it shows my reply and then shows it as received as well. So I see it twice. Also, now on some contacts it may show the contact name in my call list but that same person and number it only shows the number in messages.
For the last month, it has been really screwy and seems to change from every other day how it was going to handle the contacts. And again, I only have this issue on my phone. No issues on my iPad or Mac (iPad updated using 14.2 and Mac on current Big Sur)
The only thing that I know that I can do, but not sure the best way to do it, would be to merge my contacts from Google to iCloud and only use iCloud contacts. I really dont think that will help because the issues are not regulated to just one contact source or the other but it would take one element out of the situation. It will take a lot of work as I have a ton of contacts.
