If you’ve ever looked at the installed app list on a Xiaomi smartphone, you’ve probably noticed a strange name: ConfDialer. This system app often raises questions: what does it do, why does it work in the background and can it be safely removed? In this article, we’ll take a closer look at why ConfDialer is needed, how it relates to the functionality of the phone, and give you clear instructions on how to manage this service.
Now, let's just say, ConfDialer is not a virus or a spyware, although it sometimes seems suspicious. It's a MIUI firmware component that handles conferencing and call integration. But it's not always obvious to the user, especially if you don't use group communication. Next, we'll explain how ConfDialer interacts with the system, why it might be wasting traffic or battery, and what to do if you want to turn it off.
What is ConfDialer on Xiaomi and why do you need it?
ConfDialer (Conference Dialer) is a system application in MIUI firmware that is responsible for organizing conference calls and integrating with telephony services. It pairs with the standard Phone application and provides:
- 📞 Creating and managing group calls (conferences) over a mobile network or VoIP.
- 🔄 Integration with Xiaomi Cloud services to synchronize call history between devices.
- 📡 Supports call forwarding and line retention functions (e.g. while waiting for a second subscriber).
- 🔗 Interact with other system services, such as com.android.server.telecom (Android Call Management).
In practice, ConfDialer is activated when you:
- 📱 Combine multiple subscribers into one group call via the standard Phone app.
- 🔄 Use call or retention functions (e.g., when talking to a carrier).
- 🌐 Connect to enterprise telephone systems via SIP (if your carrier supports this feature).
However, many users never use these features, but ConfDialer remains active in the system, because MIUI integrates all possible services in advance, even if they are not in demand, and in some cases, the application can consume traffic in the background (for example, to sync data with the cloud), or drain the battery due to constant activity.
How does ConfDialer connect to other system applications?
ConfDialer doesn’t work in isolation — it’s tightly integrated with other MIUI and Android components.
| Application/service | Role in the work of ConfDialer | Can I turn it off? |
|---|---|---|
| com.android.phone (Phone) | The main call app. ConfDialer extends its conference features. | No (critical system component) |
| com.android.server.telecom | The Android system service that manages all calls.ConfDialer interacts with it to create group calls. | No. |
| Mi Cloud | Synchronizes the history of conference calls between devices. | Yes (can be turned off sync) |
| com.miui.voiceassist | Xiaomi’s voice assistant can use ConfDialer to manage voice calls. | Yes (can disable the assistant) |
If you disable or remove ConfDialer, this may result in:
- ❌ Unable to make group calls through the standard Phone app.
- ❌ Failures in translating calls or holding lines.
- ❌ Loss of synchronizing conference call history with Mi Cloud.
However, for most users, these features are not critical. If you do not use conferencing, ConfDialer can be safely disabled (more on this in the next section).
💡
Before disabling ConfDialer, check if you are using operator services that require group communication (for example, corporate rates with conferences).
How to disable or remove ConfDialer on Xiaomi?
If you decide you don't need ConfDialer, there are several ways to disable it or remove it. Important: removing system applications can disrupt the stability of MIUI, so we recommend trying the mildest methods first.
Method 1: Disconnect via settings (without root)
This method does not remove the application, but stops it from working and prevents it from starting:
- Go to Settings → Applications → Application Management.
- In the search, enter ConfDialer (or Conference call in Russian).
- Click on the application, then select Disable.
- Confirm the action. The application will stop working, but it will stay in the system.
⚠️ Warning: After disabling ConfDialer, some features of the standard Phone application may not work properly (for example, the Add Call button will become inactive).
Method 2: Remove via ADB (without root but with PC)
This method will require a computer and enabled debugging over USB:
Enable debugging on USB In Settings → The phone. → Version. MIUI (press 7 times)|Install ADB-PC drivers|Download Platform Tools from Google|Connect the phone to the PC by USB and allow debugging-->
adb shell pm uninstall --user 0 com.android.confdialerThis command will only remove ConfDialer for the current user (without affecting system files). To return the application, use:
adb shell cmd package install-existing com.android.confdialerMethod 3: Complete removal with root rights
If you have root access, you can delete ConfDialer completely using a file manager (e.g., Root Explorer):
- Go to /system/priv-app/ConfDialer.
- Delete the folder or rename it (e.g., ConfDialer_bak).
- Reboot the phone.
⚠️ Warning: Completely removing system applications may make it impossible to update MIUI over the air (OTA).
What happens if you completely remove ConfDialer?
Why is ConfDialer wasting traffic and battery?
Many users complain that ConfDialer is consuming mobile traffic or draining the battery even without active use.
- 🔄 Sync with Mi Cloud: The app can send call data to Xiaomi’s cloud (if sync is enabled).
- 📡 Background activity: ConfDialer periodically checks for updates for telephony services.
- 🤖 Firmware errors: In some versions of MIUI (especially in beta builds), ConfDialer can "hang" in the active state.
- 📱 Operator Interaction: Some mobile operators use ConfDialer to provide additional services (e.g., default conferences).
To reduce your traffic and battery consumption:
- Turn off synchronization of call history in Settings → Xiaomi Account → Mi Cloud → Synchronization → Call history.
- Limit ConfDialer background activity in the application settings (Settings → Applications → ConfDialer → Battery → Limit background activity).
- Update MIUI to the latest stable version (new builds often fix resource-consuming bugs).
If ConfDialer continues to actively consume resources, try resetting its settings:
- Go to Settings → Applications → ConfDialer → Storage.
- Click Clear the cache and Reset the settings.
💡
If the battery consumption has not decreased after the ConfDialer is turned off, the problem may be in another system application (for example, com.android.phone or MiuiDaemon).
ConfDialer and Security: Should We Be Worried?
Many users fear that ConfDialer could be spyware or collect personal data.
- ✅ Official Component MIUI: ConfDialer is standard firmware and digitally signed by Xiaomi. It's not a third-party app.
If you are concerned about privacy:
- 🔒 Turn off synchronization of call history in Mi Cloud.
- 🛡️ Use alternative calling apps (such as Signal or Google Phone) that are independent of ConfDialer.
- 🔄 Update MIUI regularly to address potential vulnerabilities.
⚠️ Warning: If you notice that ConfDialer is sending data to suspicious servers (you can check through Settings → Traffic → ConfDialer), this may be a sign of infection with a virus masquerading as a system application, in which case, perform a full antivirus check (for example, Malwarebytes) and re-flash your phone if necessary.
ConfDialer Alternatives: How to Do Without It
If you disabled or deleted ConfDialer, but suddenly you need a conference call, you can use alternative solutions:
| The alternative | Advantages | Deficiencies |
|---|---|---|
| Google Phone | Supports group calls, integration with Google Contacts. | Not all functions work on MIUI (e.g., call recording). |
| Truecaller | Spam recognition, group calls, cloud synchronization. | Requires registration, collects contact data. |
| Zoom/Microsoft Teams | Full-fledged conferences with video, recording and chat. | It requires the internet, it doesn’t integrate with phone calls. |
| SIP- Clients (e.g. Zoiper) | Support for corporate telephone systems. | The complex setup requires data from the operator. |
If you need a conference call (not an internet call), check with your mobile operator whether it supports this function without ConfDialer. Some operators (such as MegaFon or Beeline) provide their own group call services that work through USSD- commands.
Example of USSD- conference creation teams (check with your operator):

Let’s look at the common errors associated with ConfDialer and how to fix them:
- 🔴 "ConfDialer stopped" Reason: Conflict with other system applications or cache damage. Solution: Clear the cache and application data in Settings → Applications → ConfDialer → Storage. If it doesn't work, reset your phone to factory settings.
- 🔴 High battery consumption Cause: Background activity due to a firmware error Solution: Limit background activity in battery settings or turn off the app (see section above).
- 🔴 Group calls are not working Reason: ConfDialer is disabled or deleted Solution: Restore the application via ADB (adb shell cmd package install-existing com.android.confdialer) or use alternative applications.
- 🔴 ConfDialer consumes traffic for no reason Reason: Sync with Mi Cloud or an error in operation. Solution: Turn off synchronizing call history or deny the application access to mobile data in Settings → Traffic → ConfDialer.
If the problem persists after all the manipulations, check your phone for viruses or contact Xiaomi support (via the MIUI Feedback app).
💡
Before you call for support, collect ConfDialer logs using the Bug Report app (available in Settings → About Phone → Error Report) to speed up the problem.
