Owners of Xiaomi smartphones and Poco sub-brand often face an unexpected limitation: after updating the operating system, the automatic recording of conversations can disappear or stop working correctly. This is due to the transition to the standard Google Dialer, which in some regions blocks the ability to save audio files without notifying the interlocutor or even prohibits the function. For Poco X3, running on the shell of MIUI 12 or the newer HyperOS, this issue remains one of the most pressing among users who value control over communication.
There are several proven ways to return the ability to capture dialogs in automatic mode, some of which require minimal manipulation in the settings, others involve deeper intervention in the system through the use of a system. ADB-It is important to understand that the choice of method depends on the firmware version (Global, European or Chinese) and the specific version of Android.
In this guide, we will take a look at all the options available, evaluate their safety and effectiveness, learn how to activate hidden functions of a staff caller, whether to install third-party programs, and what are the risks when changing the region in the device settings. Permanent recording is not just a convenience, but an important tool for maintaining the evidence base in business and personal conversations.
MIUI and Google Dialer capabilities
You should start by checking the basic settings, as in some cases the function is simply disabled by default or hidden in the menu. X3 The global firmware uses the Google Phone app, unlike the old caller. MIUI, It has strict restrictions depending on the geolocation of the account and SIM-map.
To start checking, open the Phone app and click on the three dots in the top right corner, then select Settings. Find "Talk Record." If that's not available, the feature is software-locked by the developer for your region. If there is one, you can activate the Auto Record switch.
⚠️ Note: When you use Google Dialer in most regions, when you turn on the recording, you hear a loud beep warning the interlocutor to fix the conversation.
If you have a record menu, you can choose the numbers you want to use, so you can set up a record of all the numbers that are coming and going, only certain numbers, or only unknown subscribers, and it's a flexible tool to save space in the memory of the internal drive.
- 📱 Open the Phone app and go to settings via the menu.
- 🔍 Find the "Talk Record" section and activate the switchboard.
- 📂 Specify a folder to save if the system offers a choice between local storage and the cloud.
Note that files are saved in.m4a or.mp3 format in the Recordings/Call folder, accessed through a standard conductor, and the sound quality depends on the codec used by the carrier, but is usually high enough to parse speech.
Replacement of the region to activate the function
One of the most popular and safest ways to unlock a Poco X3 recording without installing third-party software is to temporarily change the region in your system settings. The logic is simple: in some countries (for example, India, Indonesia, Vietnam), the law allows recording calls, so for these regions Google and Xiaomi will unlock the functionality.
To use this method, go to Settings → Additional settings → Region. From the list of countries, select, for example, Indonesia or Vietnam. After changing region, you must completely close the Phone application through Task Manager and open it again. Often after that, the desired item appears in the call settings.
But this approach has its nuances: a region change could affect some system applications, such as Explorer, Themes, or Mi Video, that will start showing country-specific content, and may change the set of stickers in the keyboard.
If changing the region didn’t help the first time, try clearing the cache of the Phone app. Go to Settings → Apps → All Apps → Phone → Memory and click Clear Cache. Don’t confuse it with the Clear All button, otherwise you’ll lose your call history.
- 🌏 Go to the system settings and change the region to Indonesia or India.
- 🔄 Forced to close the phone app and run it again.
- 🗑️ If necessary, clear the call cache through application management.
In most cases, the recording setting is maintained even after the return, but sometimes the procedure is required to be repeated, which is considered the most stable method for users who do not want to obtain root rights.
Use of third-party applications for recording
If the standard methods don't work or the quality of the recording doesn't suit you, third-party solutions come to the rescue. The market offers a lot of applications, but due to the limitations of Android 10, 11, 12 and above, their work can be unstable.
One of the most famous solutions is the Call Recorder app - Cube ACR. It can bypass many restrictions using special accessibility services (Accessibility Service). To work properly on the Poco X3, you need to give the application the maximum set of permissions, including access to the microphone, phone and overlays on top of other windows.
⚠️ Warning: Third-party recorders often require the battery optimization to be disabled. MIUI/HyperOS «Kill the recording process in a few minutes to save energy.
Installation of such applications requires care. Only download software from trusted sources, such as the Google Play Store or the official developer's website. Avoid modified versions (Mod) from questionable forums, as they may contain malicious code that steals your data.
In the settings of a third-party recorder, it is important to choose the right source of sound, usually a Voice Call or a Microphone, and you need to experimentally choose a version in which the interlocutor will be heard clearly, without echoes or extraneous noises.
- 📥 Download a reliable recording app like Cube ACR Automatic Call Recorder.
- ⚙️ Provide all the permissions requested and turn off battery savings for this app.
- 🎙️ In the settings of the sound source, select the option that provides better audibility of the interlocutor.
The downside of the method is the possible availability of advertising in free versions and periodic crashes after Android updates. However, for those who need to record calls via messengers (Viber, WhatsApp, Telegram), this is often the only working option, since the regular call does not write them.
Advanced Method: Changing Regions Through ADB
For users who want to avoid visually changing the region throughout the system, but need to activate the recording function, there is a more subtle method: changing the region parameter only for a specific Google Phone application via a computer and ADB debugging bridge.
This way requires preparation. You'll need a computer (Windows, macOS or Linux), USB-cable and on-line debugging USB POCO X3. The developer menu is activated by seven times pressing the build number in the About Phone section».
☑️ Preparation for work with ADB
After connecting the phone to the PC and authorizing debugging, you need to enter a special command in the command line, which will force you to set the region for the call.
adb shell pm grant com.google.android.dialer android.permission.READ_CALL_LOG
adb shell am broadcast -a com.android.phone.SET_REGION --es region ID_ RegionWhere ID_A region is a country code, for example, ID for Indonesia or VN The exact command may vary depending on the Android version and shell, sometimes it's enough to change the system variable through a device. ADB:
adb shell settings put global region IDThe main advantage of the method is that the rest of the system stays in your home region, stores and services do not change the content. However, this is a technically complex way, requiring caution. A mistake in typing a command can lead to unpredictable behavior of the system.
| Parameter | Changing the region in settings | The method through ADB | Third-party annexes |
|---|---|---|---|
| Difficulty | Low. | Tall. | Medium |
| Impact on the system | Global (content, services) | Local (only call) | Minimum |
| Stability | Tall. | Medium | Depends on the OS. |
| Warning of the recording | There are (in most cases) | Depends on the version. | Often not. |
Using ADB allows you to get into deep settings without obtaining superuser rights. This is a middle ground for advanced users, but requires careful study of the current commands for your version of firmware.
Problems with sound quality and their solution
A frequent complaint of Poco X3 users is the low volume of recording or the complete absence of sound from the interlocutor, due to the peculiarities of VoLTE and modern codecs that encrypt voice traffic.
To improve the situation, try to disable VoLTE in the settings SIM-Cards if your operator allows you to make calls through 2G/3G. The quality of the communication may fall, but the recording will become legible, and it will also help to turn on the speaker during the conversation - the sound will be written through the main microphone.
💡
If you can't hear the other person, try to turn on speaker while you're talking, and that's guaranteed to make the microphone record the voice through the speaker, although the quality can get a little worse because of the echo.
In some cases, cleaning the dynamic speaker grid and microphones helps. In six months of operation, the Poco X3 gets clogged with dust, which critically affects sensitivity. A gentle brush can do wonders.
If you use a headset or Bluetooth headphones, you may not be recording at all. Android system restrictions often prohibit recording audio from going through Bluetooth, and in such cases, the only way out is to transfer the call to the phone speaker.
- 🔊 Check if the microphone holes are covered with a protective cover or dirt.
- 📶 Try temporarily disabling VoLTE in mobile network settings.
- 🎧 When using a headset, transfer the conversation to speakerphone for recording.
It's also worth checking the noise reduction settings. Aggressive noise cancellation MIUI can treat the voice of the interlocutor as background noise and cut it out of the recording. Experiment with the sound settings in the engineering menu, if you have access.
Legal aspects and data storage
Not only is it important to implement the recording technically, but it is also important to understand the legal implications: the laws on recording telephone conversations differ from country to country, for example, recording a conversation by a participant for personal purposes is generally allowed, but the use of the recording in court or online may be limited.
Under current law, the use of a recording of a conversation as evidence in court is only possible if you are a participant in this conversation and the recording was not obtained in violation of the law.
Record files take up space. One minute of good quality conversation can weigh about 100-200 KB. With active automatic recording, Poco X3 memory can quickly fill up, and it is recommended to regularly audit the Recordings folder or configure sync with the cloud.
Where are the records stored?
Keep your data safe. Conversation files can contain sensitive information, such as passwords, SMS codes, personal data, and make sure that access to your phone's file system is protected by a strong password or biometrics.
⚠️ Attention: Regularly check the available space on the device. Overloading memory can cause the recording of new conversations to stop or even crash the system.
Automating the cleaning process is also possible, and some third-party applications allow you to set up deletion of records beyond a certain period of time (for example, 30 days), which helps maintain order without constant manual intervention.
