How do I fix random contact blocking after iOS 27 update?

Hi there

Please try this

Unblock Manually via Settings: Go to Settings > Apps > Phone > Blocked Contacts (or Settings > Privacy & Security > Blocked Contacts on some versions). Swipe left on your mom or best friend's name and tap Delete or Unblock. 

Refresh iCloud Contact Sync: Go to Settings > [Your Name] > iCloud, tap See All or Show All under Saved to iCloud, and turn Contacts OFF. Choose Keep on My iPhone when prompted. Wait about 30 seconds, turn Contacts back ON, and tap Merge. 

Delete and Re-add the Contact: Completely delete the contact card for the affected person from your Contacts app, restart your iPhone, and then create a brand-new contact entry for them with their phone number and email. 

Reset All Settings: If the glitch keeps returning, go to Settings > General > Transfer or Reset iPhone > Reset > Reset All Settings. This will not erase your personal photos or messages, but it will return system preferences, Wi-Fi passwords, and network layouts back to default, clearing out corrupted update caches. 

Check Focus Modes: Ensure an active Focus mode isn't accidentally configured to silence or restrict notifications from specific people. Check your configuration under Settings > Focus. 

This has something to do with the google and apple turf war.

Re-enable or Refresh Gmail Contacts Sync

If your Gmail contacts are missing or not syncing after an update:

• Go to Settings > Apps > Mail > Mail Accounts (or Settings > Mail > Accounts on some versions).
• Tap your Gmail account.
• Toggle Contacts OFF, choose "Delete from my iPhone", wait a few seconds, and toggle Contacts back ON.
• Pull down to refresh your Contacts app, or restart your iPhone. https://www.youtube.com/watch?v=N4Yc8kCVLpU

Clear Out Blocked Contacts (If You Hit the Limit)

If you see a "Blocked Contacts Limit Reached" message or cannot block new senders, you may have exceeded Apple's maximum cap (around 3,000 blocked phone numbers and email addresses)

Go to Settings > Apps > Phone > Blocked Contacts (or Settings > Privacy & Security > Blocked Contacts).

Swipe left on old or unnecessary blocked entries and tap Delete or Unblock to bring your total below the limit.

3. Refresh iCloud Contact Sync Database

If blocking or contact search feels stuck or unresponsive:

Go to Settings > [Your Name] > iCloud and tap See All under "Saved to iCloud".

Turn Contacts OFF and select "Keep on My iPhone" when prompted.

Wait about 30 seconds, turn Contacts back ON, and tap Merge.

Unblock or Manage Gmail-Specific Blocks via Gmail App

If a contact or sender is blocked directly through Google rather than iOS:

• Open the Gmail app on your iPhone.
• Tap the Menu icon (three lines) in the top left and go to Settings.
• Select your Gmail address, tap Manage blocked users, and unblock the desired account.

Both my mom and I had this issue. We had to contact the phone company (tmobile for us) and they showed that when the phone updated some setting got switched so that it caused that problem, as well as blocking verification codes from certain businesses. Once they took the setting off, it was fixed.

this is happening to me to and it is a contact I communicate with multiple times a week if not daily. I even got a new phone (because it was time) and it is happening. please help if any of you have figured it out.

It happens to me too. It's v. annoying & damaging! It's not acceptable! And it's getting worse. We believe Apple uses lousy technicians who ruin the system

when taping "unblock", it doesn't do it!

Did all that, still blocked… it’s annoying, any other ideas?

Even after Reset all Settings? Really?

It happens to me too. It's so annoying and frustrating It's not acceptable! And it's getting worse. Apple should do something better!!!

for 1000 ppl??

I have done all the recommendations and the issue persists. If this many people are experiencing the same issue...the common denominator becomes the device itself.

I’m having the same issue and it’s for a delivery that I’m expecting. I went through and tried manually unblocking and I literally watched it re-block the contact by itself.
