Synchronizing calls on Xiaomi: how to work, configure and solve errors

Xiaomi’s current smartphones offer a lot of features for easy communication, and one of the most useful is call synchronization, which allows you to automatically transfer your call history between devices connected to a single Mi Account account, or even synchronize incoming calls on multiple gadgets at once, for example, you can start a conversation on a smartphone and continue it on a tablet or smartwatch without interrupting communication.

However, not all users understand how this feature works, where to find it in the settings and why it sometimes refuses to function correctly. In this article, we will discuss in detail how call synchronization works, consider the step-by-step instructions for setting up on different Xiaomi models (from Redmi Note 10 to Xiaomi 14 Ultra), and analyze typical errors and how to fix them.

What is call synchronization and why is it necessary?

Call sync is a feature that automatically combines call history between devices linked to a single Mi Account.It runs on the Xiaomi Cloud service and allows you to:

• 📱 See incoming/outgoing calls on all connected gadgets (smartphone, tablet, Mi Band or Xiaomi Watch smartwatch).
• 🔄 Continue the conversation on another device without breaking the connection (for example, switch from smartphone to tablet).
• 📊 Keep a unified call history across all devices, even if you’ve made calls from different devices.
• 🔔 Receive notifications about missed calls on all synchronized devices.

The feature is especially useful for those who use multiple Xiaomi devices at the same time.For example, you can take a call on a Redmi smartphone. K70, And then switch to the Xiaomi Pad 6 tablet if you want to turn on speakerphone or share a screen, and the user doesn't even notice the switch, and the conversation will continue without pause.

Importantly, call synchronization is different from Continue on Another Device (which runs via Mi Share), which is about automatically transferring call data between devices in real time, rather than manually transferring an active call.

How to synchronize calls on Xiaomi: technical details

To understand how synchronization works, let's look at the technical side of it, and it's built on three key components:

1. Xiaomi Cloud, which stores the history of calls and allows them to be transferred between devices, is encrypted, but the function requires a stable Internet connection.
2. Mi Account: All devices must be linked to one account, and without that, synchronization is impossible.
3. Module "Synchronization of calls" in firmware MIUI — It's responsible for the exchange of data between gadgets. MIUI 12, the function became more stable, but in early versions, bugs could occur.

When you make a call from one device, the call information is sent to the Xiaomi cloud and then distributed to all other gadgets associated with the account.

• 📶 Internet (Wi-Fi or mobile network) is required for work).
• 🔒 Data is transmitted in encrypted form, but Xiaomi can theoretically view it (like any cloud service).
• ⏱ The synchronization delay is usually 1-3 seconds.

If the Internet goes down, the call history syncs later, when you first connect to the network, but active calls (such as switching conversations between devices) require a constant connection.

💡

If you often lose your Internet connection, turn on Mobile Data in your settings. → Always active, which will help you avoid synchronization breaks.

Step-by-step: how to enable call synchronization

You can activate the function in two ways: through the phone's settings or through the Mi Cloud app. Let's look at both.

Method 1: Using the phone settings

This method works on most Xiaomi models, including the Redmi Note 12, POCO X5, Xiaomi 13T and others with firmware MIUI 12–14:

1. Open the Settings.
2. Go to the Accounts section → Mi Account.
3. Select Data Sync (or Xiaomi Cloud in some versions).
4. Find the call synchronization and activate the switch.
5. Wait until the first synchronization is completed (it can take up to 5 minutes).

Method 2: Using the Mi Cloud App

If there is no separate call point in the settings, try this method:

1. Open the Mi Cloud app (if not, download it from Google Play).
2. Sign in with your Mi Account.
3. Go to the Synchronization section.
4. Find the Call Log and enable synchronization.

Once activated, check that the feature is working: call from one device and make sure the call is displayed in a story on another.

What Xiaomi devices support call synchronization

The feature is not available on all Xiaomi models, but here are the basic requirements:

• 📱 Smartphones: All models on MIUI 12 and newer (e.g. Redmi Note 11, Xiaomi 12, POCO F5).
• 📱 Tablets: Xiaomi Pad 5/6 last-fixed.
• ⌚ Smart watch: Xiaomi Watch S3, Mi Band 8 Pro (Call Support).

On older devices (e.g. Redmi) 9A or Mi A3) The feature may be missing or unstable, and call synchronization is not supported on custom firmware devices (such as LineageOS) unless Xiaomi services are integrated into them.

If your device doesn’t support the feature, but you want to sync calls, you can use third-party solutions like Google Contacts (for history) or apps like Call Sync. However, they won’t be able to switch active conversations.

Typical problems and their solutions

Even if synchronization is enabled, users often encounter errors.

1.Synchronization doesn't work at all

If the call history is not updated between devices:

• 🔄 Reboot both devices.
• 📶 Check the Internet connection (synchronization requires a network).
• 🔧 Update. MIUI last-minute.
• 🔄 Manually run synchronization in Mi Cloud → Synchronization → Update.

2.Calls duplicate in history

This happens if the same device sends data to the cloud several times.

• 📱 Turn off sync for 10 minutes, then turn it on again.
• 🗑 Clear the cache of the phone application in the settings.
• 🔧 Reset your Mi Cloud settings (as a last resort).

3. Active call switching is not working

If you can’t switch the conversation to another device:

• 📞 Make sure both devices support Wi-Fi Calling (required for smooth switching).
• 🔄 Reconnect to the Mi Account.
• 📡 Check that both devices are connected to the same Wi-Fi network.

⚠️ Warning: If sync is still not working after all the manipulations, check if your operator or firewall is blocking access to Xiaomi Cloud.

Security: Call Synchronization Risks and How to Minimize Them

Sharing your call history to Xiaomi’s cloud raises privacy concerns, and here are the key risks and ways to mitigate them:

1. Access to third party data

In theory, Xiaomi employees or hackers (in case of a leak) can access your call history to reduce the risks of:

• 🔐 Use two-factor authentication for Mi Account.
• 🔄 Change your account password regularly.
• 🚫 Do not connect devices to your account that you do not trust.

Data leakage during transmission

While Xiaomi claims that data is encrypted, it is impossible to completely rule out the risk.

• 📵 Do not use synchronization on public Wi-Fi networks.
• 🔒 Turn it on. VPN When connected to questionable networks.
• 📱 Turn off sync if you don’t use it temporarily.

3 Unauthorized access through the Lost Device

If your smartphone is stolen, an attacker can access your call history through the cloud to avoid this:

• 🔄 Set up remote data erasure in Mi Cloud.
• 📱 Turn on the lock. SIM-PIN-code.
• 🔐 Use the settings. → Security → Blocking applications for the Phone application.

If privacy is critical to you, consider disabling call sync and using local backup (e.g., via Google Drive or Titanium Backup).

💡

Call synchronization is convenient but not secure, and if you're working with sensitive information, it's best to opt out of cloud sync or use it selectively (for example, for history only, without switching active calls).

Alternative ways to synchronize calls

If the built-in Xiaomi feature does not suit you, you can use third-party solutions:

1. Google Contacts and Call Log

Google offers its own synchronization of call history through Google Contacts and Google Dialer.

• 🌍 It works on all Android devices, not just Xiaomi.
• 🔒 Data is stored in Google Cloud, which may be more secure for some users.
• 📱 Easy to set up through your Google account.

Cons: There is no way to switch active calls between devices.

2. Third-party applications

There are specialized applications for synchronization, for example:

• Call Sync syncs the history between devices through the cloud.
• Sync.ME – additionally shows information about callers from social networks.
• Truecaller synchronizes calls and blocks spam.

However, these solutions have drawbacks:

• 🚫 Additional permissions (access to contacts, calls).
• 💰 Often contain advertising or paid features.
• 🔒 It can be less secure than the solutions from Xiaomi or Google.

Manual backup

If you only need a call history (without automatic synchronization), you can manually export the data:

1. Open the Phone app.
2. Go to the Call Journal. → ⋮ → Exports.
3. Save the file (e.g., on Google Drive or on your computer).

This method is inconvenient for regular use, but it guarantees complete control over the data.
