Owners of Xiaomi, Redmi and POCO smartphones often face a frustrating situation: after upgrading the system or buying a new device from Europe or a global version of firmware, the automatic call recording feature disappears, due to stricter privacy laws in several countries, which forces the company to implement regional restrictions on the software.
Fortunately, even if the default Phone app is missing a setup slider, there are proven ways to get that back, depending on the version of the MIUI shell or the new HyperOS, and the region in which your device is registered, solutions can range from simply changing locations to installing third-party utilities. It's important to understand that recording conversations at the system level provides the best audio quality, because it uses a direct audio stream rather than a microphone.
In this article, we’ll look at all the current ways to activate the feature, including changing the region through an engineering menu and using specialized substitute applications.You’ll learn why recording quality depends on the method you choose and which models, such as the Redmi Note 12 or Xiaomi 13, may have hidden limitations.
Why the recording function in the phone application disappeared
The main reason for the disappearance of the regular feature lies in the legislation of the European Union, in particular in the GDPR (General Data Protection Regulation), which strictly regulates the processing of personal data, which includes the voice of the interlocutor.To avoid violating laws and avoid multi-million dollar fines, Xiaomi software blocks the recording function for devices sold in certain regions.
When you buy a smartphone, a Global version or a European version (EEA), The default setting is the region, and even if you're in a country where recording is allowed (e.g. Russia, Ukraine or Kazakhstan), the system thinks it should comply with European standards, which is why there's no switch in the call settings menu.
⚠️ Warning: Forced activation of hidden functions by changing system files can cause the Phone app to run in an unstable way. Always back up important contacts.
It is worth noting that this is a rare problem on CN Version devices, as China has different rules for regulating the digital space, but flashing the Chinese version to the global version often results in a loss of functionality if you do not manually change the region immediately after the first turn on.
In addition, in the latest updates to Android 13 and Android 14, Google also implements its own core-level restrictions, which means that even third-party apps from the Play Market may not work properly or require complex accessibility settings to intercept the audio stream.
Replacement of the region through system settings
The easiest and safest way to do this, which works on most Xiaomi and Redmi models without getting root permissions, is to change the region in the general settings of the smartphone. The logic is simple: we tell the system that we are in a country (for example, India, Singapore or Russia) where recording calls is legal and allowed.
You don't need a computer or a special cable to do this, you do it directly in the interface of your smartphone, you first have to open the settings menu and find the location of the device, which is usually in the "Advanced" section or right in the list of basic parameters.
After changing the region, the system may require a reboot or simply update the list of available features in the applications. If the method works, the Phone application will be able to turn on the record automatically or on a button during a conversation.
It's important to understand that changing your location may affect some services, such as Mi Pay or your browser feed, but for basic phone functionality, this change is unnoticed, and if you don't have a record slider after you change your location, your firmware version is more restrictive and you'll need to use alternate methods.
Activation via Engineering Menu and ChangeLocale
If a simple change of region didn't help, you can try a deeper method, which is changing the system locale through an engineering menu or a special utility, which allows you to change the country code at the system level, which often causes the Phone application to redraw the interface and add elements.
One popular way to log in to the engineering menu is to type ##4636## in the call app. If the menu opens, look for the section that is associated with phone information or network settings. However, newer versions of HyperOS often block this entry by developers.
And then the ChangeLocale app or its analogues come to the rescue, and it allows you to force the system locale to, for example, be placed on a computer. en_IN (India) or ru_RU (Russia, even if the region is not selected in the main settings, after the changes are applied, the phone must be restarted.
| Region | Locale code. | Probability of success | Impact on the system |
|---|
| India | en_IN | Tall. | Minimum |
| Singapore | en_SG | Medium | Minimum |
| Vietnam | vi_VN | Tall. | Possible font bugs |
| Indonesia | id_ID | Medium | Minimum |
The use of this method requires caution: the wrong region can cause some system labels to become unreadable or disappear. India is considered the most stable region for activating a record without side effects.
What to do if the engineering menu code doesn’t work?
If you don't open the menu with #4636##, you're blocking the access from your firmware version. In this case, use a third-party ChangeLocale app from the Play Market or Mi Store that emulates the process softwarefully.> Using third-party applications to record When the feature fails to be activated by built-in tools, third-party developers come on to the scene. Call recording apps use various audio interception technologies. Some write sound from the microphone (which is worse in quality), others try to infiltrate the system call process. One of the leader in this niche is Call Recorder's application - Cube ACR. It has a powerful engine that can access to the phone, but it needs extensive permissions to use. 📱 Cube ACR — Supports VoIP calls (WhatsApp, Telegram, Viber) and regular calls, has cloud storage. 🎙️ Automatic Call Recorder – simple interface, automatic recording, ability to mark important calls. 🛡️ TapeACall – works via conference call (requires subscription), is suitable for iPhone and Android. 📼 Blackbox Call Recorder is a minimalist design, support for Google Drive, work in the background. It should be noted that on Android 11, 12, 13 and 14, Google actively fights these applications. The system can block the recording of sound during a conversation, and you will hear only your voice or silence. In such cases, applications may suggest using hands-free mode to improve the quality of recording through the microphone. If an application requires access to contacts, microphone, phone and storage, that's OK for its functionality. However, avoid questionable low-ranking programs that can transfer your conversations to third parties. Set up automatic recording and formats If you managed to activate the embedded record (through a change of region or initially), it is crucial to properly configure its behavior. The standard MIUI Dialer or Google Dialer application allows you to flexibly manage the process of saving audio files. First of all, you should turn on the "Write automatically" function. This will save you from having to search for the recording button at the beginning of an important conversation every time. You can configure filters: you can configure its behavior: you only to record a certain format, you need to record all the list of the list of the number. Usually available options MP3 and WAV (or AAC). Format MP3 It takes up less space but may slightly reduce quality. WAV It makes for better sound, but the files will weigh more. ⚠️ Attention: When you turn on automatic recording, make sure that the device has enough free memory. Long, high-quality conversations can quickly fill the internal storage. Remember to check the records folder regularly. In the file manager, they are usually on the way. MIUI/sound_recorder/call_rec or in a folder Recordings/Call_rec. It is recommended to periodically transfer important files to the cloud or computer, so as not to lose them when resetting settings. 💡Use Google Drive, Mi Cloud to automatically sync your call records folder. This will save your data in case of loss or breakdown of your smartphone. Problems with recording in messengers (WhatsApp, Telegram, Viber) Special attention deserves recording of calls over the Internet (VoIP). Embedded Xiaomi tools, as a rule, can not record conversations in WhatsApp, Telegram or Viber. This is due to the fact that these applications use an encrypted data channel other than conventional telephony. To solve this problem again will require third-party applications, such as the Cube ACR. However, even they do not guarantee 100% success. On new versions, the security system can block recording of sound from Android in other applications using the voice-based phone or the second voice-onerving method in the background. Some users also resort to screencasting (screen recording with sound), but this is inconvenient, as it requires a constant on screen. Use this feature only for personal purposes and subject to the laws of your country. Frequently Asked Questions (FAQ) Does recording of conversations affect the quality of communication? No, the recording process itself does not affect the quality of voice communication. Recording occurs locally on the device and does not consume additional traffic (unless real-time cloud synchronization is used). However, using third-party applications with a microphone and screen on can slightly increase battery consumption. Where do call recordings after a reset affect the quality of communication? Pre-copy important files to your computer or to the cloud. Can you record calls to Xiaomi with global firmware without changing the region? With regular funds, it is almost impossible. Global firmware is strictly sharpened under the laws of GDPR. The only option without changing the region is the use of third-party recorder applications, but their effectiveness on new Android is limited. Why does the record break or the file is empty? This is a frequent problem on Android 10 and above. The system blocks access to the audio stream. Try in the settings of the application recorder to enable the mode "Bying restrictions" or "Write through the microphone", although the quality of the official applications, if you use MiPlays, if you use them from the official stores. These apps only change the system flag of the region and do not have access to your personal data, passwords or banking applications, and once the record is activated, they can even be deleted, the setting is often saved.
