iPhone call history shared between devices after iOS 17 Update

on my primary device I have iCloud -> contacts turned off, also handoff is turned off on both devices.


Before iOS 17.0, each of my 2 devices has its private call log & contacts.


After iOS 17.0 on both devices, I started to see the call history of both devices on my primary device.

I carry 2 iPhones with the same Apple id since ages, and I don’t want to get confused by which phone initiated personal or business calls.

Its unreasonable to maintain more than one Apple ID after all of this years.

I already reported a bug to Apple. And I came here to see if anyone else noticed/fixed this.


It's not a bug. If you carry two phones – one for work, and one for personal use – for "security" reasons, then it stands to follow that you should "firewall" your accounts and have two Apple ID accounts, as well.


The call history sharing might be new, but there is all sorts of other sharing linked to having the same Apple ID. Sharing that's been around for a long time. E.g., keychain passwords, photos, contacts, calendars, reminders, notes, and files on iCloud Drive.


iMessages are also linked to your Apple ID, whether you use "Messages in iCloud" or not.

My wife and I have separate ids for messaging and face time but share an id for everything else so we have a shared calendar and notes there is currently no way to separate the phone from the calendar and notes like there is with messaging. Apple needs to fix this ASAP.

There is nothing for Apple to fix. You need to stop sharing gan ID.

There are incredibly simple ways to share things like calendars and notes without sharing an Apple ID/iCloud account.

Sounds like its worth logging calls with Apple and complaining to get this resolved


The resolution has been repeatedly posted here. Shared Apple IDs share data. Always have. Always will. Stop sharing.


Further sharing of other data wouldn’t surprise in some future iOS version, as well.


Y’all can either deconflict your data now, or go through more effort to deconflict your data in the future.


And hopefully, y’all never hit a bump in your relationships here too, and get your devices bricked and your data permanently deleted.

I wanted to share my case as well.


Facts as of 1/2/2024 11:00 AM:

iOS Verion 17.2.1 on iPhone 14 Pro Me iPhone 15 Pro Wife running iOS 17.1.1

iCloud Drive Off both iPhones

iCloud Phone Off both iPhones

iCloud Contacts Off both iPhones

Live Voice Mail Off both iPhones


As of 11:11 I am receiving my wife's missed calls and voice mails. There is a "clue" when I call my wife's cell number the photo associated with my Apple ID profile is displayed. This suggests the issue may be related to shared Apple IDs vs iCloud accounts.

Caper1111 posted a solution multiple times in this thread. It’s a bandaid that result in a frequent reminder that not everything is being sync’s but it works for both those sharing an ID and those not sharing an ID.

It's not a good solution nor a good bandaid. And when people lose things because they were no longer syncing anything, they'll be upset. I know you just don't want to admit it, but the ONLY true solution is to STOP sharing an Apple ID. OR......accept merged call logs/voicemail messages.

I have been reading several Community posts about the call history voice mail history issue post upgrade to IOS 17.x. My wife just texted me a confidential work-related voice mail which landed on her iPhone.


The next thing I will try is to remove my wife as an "emergency contact". I will keep everyone posted in case this works. It would be interesting to know if those observing the "bug" have the other iPhone owner set up as an emergency contact. We share an APPLEID and iCloud ID with my son who is not experiencing the call history and voice mail sharing issue. He is NOT set up as an emergency contact. This is worth a try.
