How to Enable Call Recording on POCO X3 NFC

Owners of POCO smartphones often face a situation where the usual automatic fixing of incoming and outgoing calls ceases to work or does not work at all after an operating system update. This is due to changes in Google Android security policy that restrict access to the microphone by third-party programs and system modules during a conversation. For the POCO X3 NFC model, the issue remains especially relevant, since the device came with different versions of the MIUI shell depending on the region.

There are several proven methods to get back the ability to save audio recordings of dialogs. The key is to understand which version of firmware (Global, EEA or China) is installed on your gadget, because the availability of native tools depends on it. In some cases, you will have to resort to installing specialized software that can bypass system restrictions through the availability service.

In this article, we will discuss all the current ways to solve the problem, from hidden system settings to installing modified versions of a standard call, you will learn why standard applications from the Play Market store may not work correctly and how to properly configure the device to work smoothly for this important function in everyday life.

Native MIUI settings and regional restrictions

The first thing to check before installing additional software is the built-in capabilities of the MIUI shell. In some regions, such as India or China, the recording feature is built into the system phone and does not require additional permissions, however, for users in Europe and Russia using global firmware, this tool is often hidden or removed due to the GDPR regulations.

To check for hidden options, you can use the Phone settings menu. Open Settings → App System → Phone. If you see Call Record on the list, you are lucky enough to activate the Call Record automatically slider and select the mode (all numbers or only favorites), in which case you use a built-in audio codec that provides the best sound quality without interference.

⚠️ Note: If the phone’s settings menu does not include the Call Record section, it means that your firmware version forcibly blocks this feature at the system level, and it will not work to activate it through the standard interface.

Sometimes, changing the region in the basic settings of a smartphone helps. Go to Settings → Additional settings → Region and select India or Singapore. Once you change the location, the interface may change, and a recording button will appear in the standard call during a conversation. However, this method does not work on all versions of Android, as Google gradually unifies the requirements for all markets.

Use of third-party recorder applications

If system constraints prevent the use of embedded tools, third-party development comes to the rescue, and the most effective solution at the moment is the Appliqato Automatic Call Recorder app or its counterparts, such as Call Recorder - ACR. These programs use special access mechanisms to intercept the audio stream.

Once installed from Google Play or an alternative store, you need to give it extended rights. Android will be persistently alerted about the risks, but to work properly, the recorder needs access to a microphone, phone and, most importantly, a special accessibility service. Without activating this service, recording in new versions of Android (10, 11, 12, 13) will not be maintained.

• 📱 Download a proven recorder application from an official store or a reliable source.
• 🔐 Provide all requested permissions, including access to contacts and microphone.
• ⚙️ Activate the availability service for the application in the system settings.
• 🎙️ Enable VoIP or Alternative Recording in the recorder settings if the standard one doesn’t work.

It's important to understand that recording quality through third-party applications can vary. Often, the interlocutor is heard quieter than the owner of the phone, or vice versa. To improve the situation in the settings of the recorder, you should experiment with the sound source, choosing the option of Voice Call or Voice Communication. It is also worth turning off the energy savings for the recorder application so that the system does not "kill" the process in the background.

Replacement of the standard application "Phone"

One of the most radical, but effective methods is to replace the standard Google Dialer application with a modified version of it or a call from MIUI. The standard dialer from Google has strict restrictions and does not allow you to record without warning the interlocutor about the beginning of the recording of the conversation (hear the characteristic sound).

Installation of modified APK-Google Dialer file with unlocked recording function allows you to return the native interface, but with a working write button, 4PDA or XDA When installing, it is important to download the version that matches your version of Android, otherwise the application may not start or work incorrectly.

An alternative is to install the MIUI’s Phone system application. This method requires deeper system intervention and is often impossible without root rights or an unlocked bootloader, as system applications are protected from overwriting. If you have access to a file system with superuser rights, you can replace the com.google.android.dialer package with the com.miui.global.packageinstaller (or similar for a call) package by making a full backup.

⚠️ Attention: Replacement of system APK-Files can lead to unstable operation of the communication module, loss of call history or even cyclical restart of the device.

Configuring sound sources and codecs

The quality of the recording depends on the source of the audio signal chosen. In modern smartphones, including the POCO X3 NFC, the sound architecture has become more complex, and simple capture from a microphone often gives a quiet result. In the settings of advanced recorders, you can find various sources such as Mic, Voice Call, Voice Communication and Voice Downlink.

The optimal choice for most scenarios is Voice Communication mode, which forces the system to process the sound as if there is a video call or conversation through the messenger, which often allows you to bypass the restrictions on capturing the audio stream during normal audio streams. GSM/VoLTE If you hear yourself well but you don't, try to switch to Voice Downlink, which only captures the incoming stream.

You also need to look at noise reduction settings. Sometimes aggressive noise cancellation of a smartphone cuts off the voice frequencies of the interlocutor, considering them as background noise. Some recorders have the option to turn off the sound processing or select a particular microphone (main or secondary), Experimenting with these parameters can take time, but the result of a clean record is worth it.

Below is a table to help you choose the right sound source depending on your symptoms:

💡

For better microphone recording (Mic mode) during a conversation, do not close the lower part of the screen where the main microphone is located with your palm, and try to keep the phone in a standard position near the ear.

Problems with VoLTE and telecom operators

VoLTE (Voice over LTE) technology, which allows calls to be made over 4G networks, makes its own adjustments to the recording process. Because voice is transmitted as digital data packets rather than an analog signal, it becomes technically more difficult to intercept it. Some operators encrypt this stream, making it impossible to record with standard software methods without deep modification of the system.

If you notice that the recording is working through 3G, but disappears when switched on 4G, The problem is VoLTE, and the temporary solution is to force the smartphone to switch to mode. 3G/2G (Prefer 3G) through the engineering menu or network settings (Settings) → SIM-maps and mobile networks → Network type) However, this will result in reduced communication quality and Internet speed during the call.

In some cases, it helps to disable the function «HD-call-ups SIM-Go to the settings. → SIM-maps and mobile networks → Choose. SIM → Use VoLTE and disable this setting. After that, the phone will use standard channels. 2G/3G for voice communication, which are easier to record by software.

⚠️ Warning: Disabling VoLTE can lead to the fact that in areas of uncertain reception 3G The communication will be cut off as modern operators actively redistribute frequencies in favor of the new system. 4G/5G.
