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 senior citizen parents are using the same apple id as they don't know how to access id's etc. now the calls I am receiving the same is showing in my parents phone, my missed calls are showing in my parents phone and they are giving them call back by thinking that they missed somone's call. How come apple belives that this isn't an issue or how apple intended to work it like this way by sharing your call details with other devices? There must be some settings or some sollution regarding the same. Even i have done all the resolution regarding this by turning off icloud drive, contants in icloud as well as airplay and handoff, even though it is sharing the same.

Yes I was trying that too, toggle off contacts for example, even if I don't share my ID with other people only with my devices. The iCloud sync means what is on your iPhone can also be saved on the iCloud server so in case you need to reset the iPhone is not going lost, you can chose what you want to sync, like Photos, mail, notes etc all listed in Show All

Sign in and use iCloud.com – Apple Support

Yes but the thing is, I can own 2 iphones, one private and one for business. I don't want them to share Call history but I have the right to use my apps and other thing on both of them since I am the owner.

Your absolutely right. You do have the right and Apple even gives you the ability to share apps across devices on different Apple IDs. That's exactly why Apple created Family Sharing.

Me neither. And all other users don’t even acknoledge that if me, myself and I are not a family. I as one person do not want to pay for the family use of Apple Music. The argument that Apple does not want sharing is absolute nonsense. As Apple even indicates this option as a uniques selling point for their AirPods. Easy to use on all devices with the same Apple ID.

Instead of arguing your point with other users, many of whom are in agreement with you, yet none of whom can change this, surely you've told the only entity that could possibly do anything about this? You can tell Apple what you think here --> Feedback - iPhone - Apple

I did not say two iphones, I said devices, mac, ipad, apple tv, etc. So as per this topic argument, all users should have a different ID for every device they own, than whats the point in owning apple products anymore.


It seems to me that apple’s latest choice to sync data between all devices uncontrolled by the user. So do all households go to one Apple device going forward?

After reading that article I did not think a security breach like that was even possible. So family sharing functionality of the ID is at risk as well.

Not at all. I have an iPad, iPhone, Apple Watch, MacBook Pro. All with the same Apple ID. I can do banking on any of those devices, because they are mine and I expect my data to be accessible on all of them.


You're taking this off on another topic altogether. This thread is because people who are sharing the same Apple ID on two iPhones (regardless of why they are) are seeing their call logs and voicemail messages on both devices.


I'd suggest you stay on topic because your banking analogy has nothing to do with this thread. But if you are concerned about your banking data being accessible on your two iPhones, then you shouldn't use the same Apple ID on both iPhones. Still, that's a completely different topic.

This is interesting. I remember resetting network settings on both phones in the first weeks after updating to iOS 17, but the issue came back after a few hours - or maybe the next day - anyway, it didn’t solve it.

I cannot test this now because my second phone is in a non-sync state (thanks a million to Caper1111) and I don’t want to risk syncing again, as it took me days of logging off and on in iCloud to finally get the “Some iCloud data isn’t syncing” message.

Please let us know if something changes in the following days, maybe something has changed with the latest updates.


Thank you!

Same issue I am facing. Since more than 7 years I am using same iCloud on all devices and not facing this kind of confusing! I can't see the reason behind not giving the option to allow this or not. Its really annoying and creating a headache as I have personal work and other things which should be separated. We need a quick solution for this issue as soon as possible!
