iOS 27.1 issue blocking contact

A Previous user mentioned that deleting the affected contacts and re adding them fixed the issue for them. Another mentioned that turning "Contacts" off in cloud then purging the Icloud backup of contacts (Wont delete contacts on your actual phone) and then turning contacts back on in icloud (If you wish) ensures the issue wont come back

Thank you.

I did deleting and re adding but it not working. now, I try hit the unblock and then add the contact to Favorite. It work!!!

but anyway this not supposed to happen!!!

• From the Phone app, tap Recents, then tap the phone number or contact you want to block or the Info button  in Classic view. Scroll down, then tap Block Caller.

Block phone numbers, contacts and email addresses on your iPhone or iPad - Apple Support (IN)

Classic and Unified View

• I use the classic view to block callers. Tap the More Info button  next to the name of the Contact in the Recent list of calls.

After updating to iOS 27.1,

Not every issue an individual encounters on their device can be attributed to an iOS update. iOS 27 or later may have coincided with what you are experiencing, but that does not mean the issue was triggered by iOS. Coincidence in timing is not, by itself, evidence of causation.

If the update itself were the root cause, then every device running that same version of iOS would exhibit the identical problem. In such a scenario, the forums would be flooded with countless posts reporting the same malfunction, creating an unmistakable wave of complaints that no one could possibly overlook.

The absence of such widespread reports strongly indicates that the issue is not a general, system-wide problem with iOS 27 or later, but rather something specific to the individual device, its configuration, installed apps, settings, hardware, or another interacting factor.

In short: iOS 27 or later may be a coincidence in timing, but there is no basis to conclude that iOS itself triggered the problem simply because the issue appeared after the update.

See what each update does: About iOS 27 Updates, About iOS 26 Updates, About iOS 18 Updates, About iOS 17 Updates, About iOS 16 Updates, About iOS 15 Updates, About iOS 14 Updates, About iOS 13 Updates, About iOS 12 Updates, and so on...
