TL;DR Version
If you want to maintain private call history between your iOS devices, you need to:
Why Is Your Call History Shared?
The simplest answer to this is that both of your iPhones are using the same iCloud account.
You might wonder why this wasn’t an issue before iOS 17. The answer lies in a bug within iOS 17 that affects the synchronization settings for the Phone app.
This bug causes the system to behave as if iCloud sync for the Phone app is enabled, leading to call histories being shared across devices.
How to Maintain Private Call History Across Devices
1. Update Your iPhone to the Latest Version
The most effective solution is to wait for an official fix from Apple, which will be provided in a software update.
To check for updates:
- Open Settings on your iPhone.
- Go to General > Software Update.
- If there’s an update available, tap Download and Install.
- Follow the on-screen instructions to complete the update.
Important Notes
- The update process may restart your iPhone several times.
- Ensure your iPhone has at least 50% charge, or keep it connected to a charger during the update.
- Major updates (e.g., from iOS 15 to iOS 16) could take about 15 minutes.
To set up automatic updates:
- Go to Settings.
- Navigate to General > Software Update > Automatic Updates.
- Turn on Download iOS Updates and Install iOS Updates.
2. Turn Off iCloud Sync for the Phone App
Another method is to disable iCloud sync for the Phone app. Despite the known issue with the toggle switch, it’s worth attempting to switch it off and then restart your device.
Here’s how:
- Open Settings on your iPhone.
- Tap your Profile at the top.
- Navigate to iCloud.
- In the Apps Using iCloud section, toggle the switch next to Phone to OFF.
- Restart your iPhone.
Note
Be sure to repeat these steps on each iPhone that is linked to the same Apple ID.
3. Switch to a Different Apple ID
If the syncing issue is particularly bothersome, consider using separate Apple IDs for each of your devices. This will prevent the faulty Phone app sync settings under iCloud from affecting you.
Here’s how you can switch to another Apple ID:
- Open Settings on your iPhone.
- Tap on your Profile at the top.
- Scroll down to the bottom.
- Select Sign Out and follow the on-screen instructions.
- After signing out, create and use a different Apple ID for one of your devices.
4. Send Feedback to Apple
One of the most effective actions you can take is to report the issue to Apple. The more users report the problem, the quicker Apple is likely to address it. Submitting feedback is a straightforward way to inform Apple about the call history issue.
