Xiaomi smartphone owners, including the popular Poco X3, often face an unexpected problem: the regular feature of recording telephone conversations is either missing or not working correctly. This is due to changes in the security policy of the Android operating system, which in recent versions restricts access to the microphone during a call. For many users, the ability to record important agreements, witness testimony or just order details is critical.
To make matters worse, the interface and feature set may differ from region to region and across MIUI or HyperOS firmware, and if the global versions have a loud-notice Google Phone pre-installed, the Chinese builds or older versions of MIUI Dialer recorded automatically and unobtrusively to the other person, and understanding the differences between these components is the first step to solving the problem.
In this guide, we will discuss in detail all the available ways to activate recording on Poco X3. We will consider not only standard settings, but also methods of circumventing restrictions through the installation of alternative versions of applications, as well as the use of third-party software.
Features of the call on Poco X3
The biggest challenge is which call app is installed by default, and today's Poco smartphones are most commonly used by Google Phone, which is a very strict privacy standard, so when you start recording, you hear a loud beep that both people hear, and you can't turn off that notification by standard methods.
The alternative is MIUI Dialer (or HyperOS Dialer), which was originally developed for the Chinese market but is often installed by enthusiasts, and in this version, the recording functionality is built deep into the system and allows you to record automatically, without warning the other party, but the installation of this component requires caution, since replacing system applications can lead to conflicts.
⚠️ Note: Install modified versions of system applications (such as: MIUI Dialer on global firmware can lead to unstable interface operation or inability to make calls. Before any manipulations, make a full backup of the data.
And then there's the Android version. Since the eleventh version, Google has implemented strict restrictions on access to audio, and even if the app formally supports recording, the system can block the capture of the audio of the other person by recording only silence or your own voice through the microphone, which is why the choice of method depends on the specific software build of your device.
Use of built-in MIUI and HyperOS functionality
Before resorting to complex methods, you need to check the standard features of your system. In some regions (for example, Indonesia, Vietnam, Russia in individual builds), the recording function is built into the native call. To check, open the Phone application and go to settings through the menu or button with three dots.
If you're lucky, you'll see Call Record, and in this section you can activate automatic recording of all incoming and outgoing calls, or select specific numbers, and the files are stored in the device's internal memory, usually in a folder. MIUI/sound_recorder/call_rec. Access to these files is through a standard conductor.
However, if the call settings menu doesn’t have the appropriate items, your region or firmware version doesn’t support this feature out of the box, and then attempts to activate it through hidden codes or engineering menus are often unsuccessful on newer versions of MIUI.
💡
Check the region of the device in the settings "Additional" → "Region." Sometimes changing the region to Indonesia or India can activate hidden call functions without flashing.
Replacement of calls with MIUI Dialer (Method for Advanced)
The most effective way to get a full recording without sound signals is to replace the standard Google Phone with a new one. MIUI Dialer: This method requires removing updates to the standard application and installing a special application. APK-The process requires care, as the steps may vary depending on the version of Poco. X3.
First, remove updates to the standard Phone app. Go to Settings → Apps → All apps, search for Phone (Google) and click “Delete Updates”. After that, find and download the current version of MIUI Dialer for your Android version (11, 12 or 13).
After installation APK-You can have the file and you can give all the permissions you need, you can have a write button in the call interface, you can set the new application to automatically record. MP3 or M4A and will be available for listening immediately after the conversation is over.
☑️ Checklist for the replacement call
It is worth noting that Google periodically blocks older versions of the call, requiring an update, so it is recommended to find a modified version of MIUI Dialer with a blocked update or use tools to freeze system updates, which will preserve the recording functionality in the long run.
Third-party applications for recording conversations
If you think it’s too risky to replace your system call, you can use third-party apps from Google Play. However, the choice is limited: most of them stopped working correctly on Android 11+. However, some developers have found workarounds using Accessibility Service to manage the record.
One of the most popular solutions is the Call Recorder app, Cube ACR, which can bypass system limitations but requires careful adjustment, and once installed, you need to give the application the maximum set of permissions, including access to a microphone, phone and, most importantly, a special feature service, without which the interlocutor will not be recorded.
Other applications, such as TapeACall or Automatic Call Recorder, can use a conferencing recording method, in which case, when you start recording, the system connects you to the recording server, creating a conference, the disadvantage of which is that you have a paid subscription and a third-party number on the call list.
| Annex | Working on Android 12/13 | Root is required. | Features |
|---|---|---|---|
| Cube ACR | Partial (to be adjusted) | No. | Uses accessibility service |
| Call Recorder - SKVALEX | Yes (paid) | No (but need ADB) | High quality, flexible settings |
| Blackbox Call Recorder | Depends on the device. | No. | Trying to use system APIs |
| TapeACall | Yes. | No. | Recording through the conference (paid) |
⚠️ Warning: Third-party applications can consume a significant amount of Poco battery power X3 Check your energy consumption statistics regularly to avoid rapid discharge.
Customization of quality and format of recording
The quality of the recording directly affects the intelligibility of speech. In the settings of MIUI Dialer or third-party applications, you can choose the coding format. The optimal choice is MP3 with a bit rate of at least 128 kbit / s or AAC. WAV format provides the best quality, but files take up much more space, which can be critical for long conversations.
It's also important to adjust the sound source. Ideally, you should choose Voice Call (VoIP) or Microphone. If you hear yourself well and the person you're talking to can barely hear, try changing the source to Dynamic and holding the conversation in hands-free mode, which will allow the microphone to capture the sound from the speaker, although the quality may be lower due to the echo.
For users who often record important conversations, it is recommended to set up automatic cleaning of old files or synchronizing them with the cloud. Record files can quickly fill the internal Poco X3 drive, especially if high-quality recording is enabled. Regular archiving of data will help avoid memory shortages.

Legal aspects and ethics of recording
The use of the telephone recording function is regulated by the legislation of your country. In many countries, including the Russian Federation, recording of the conversation is allowed and does not require warning of the interlocutor, unless this data is transmitted to third parties and published.
However, if you plan to use the recording as evidence in court or make it public, the rules may be stricter, and some jurisdictions require the other party to be notified of the recording, and ignoring these rules can lead to legal liability.
Technically, having a record can protect your rights in disputes with banks, delivery services or unscrupulous sellers, so having a working recorder on Poco X3 is an important element of user digital security.

Recording a conversation without notice is allowed for personal use by the participant in the conversation in most CIS countries, but the publication of such recordings may be illegal.
