How to record a call on Xiaomi Redmi Note 9: a detailed guide

Modern Redmi smartphones often come with a MIUI shell that has its own features in managing multimedia and calls. Redmi Note 9 users often face a situation where the standard voice recorder function during a conversation is not activated or hidden by developers due to the legislative restrictions of individual regions. Recording telephone conversations can be critical to retain important information, confirm agreements or fix fraudulent actions, so the absence of an obvious button is puzzling.

In this article, we will take a closer look at all the available methods for activating this feature on your device, we will look at both the built-in features of the system and proven third-party solutions that bypass software limitations, you will learn where to look for hidden settings and how to properly adjust the quality of audio files.

To begin with, Xiaomi can implement different versions of the firmware to access the microphone during a call. In some cases, the function is simply disabled software, in others, you need to change the region or install a special patch. Understanding these nuances will help you avoid installing malicious software.

Built-in recording function in the Phone application

The first and logical step is to check if a native feature is present in a standard call. The MIUI shell that the Redmi Note 9 has is often equipped with, but it may be inactive by default. To check, open the Phone app and look for the gear icon or three dots in the corner of the screen.

Go to the Settings menu and carefully review the options list. If you're lucky with the firmware version or region, you'll see Call Record. Inside this section, you'll usually have automatic write settings for all numbers or only for selected contacts from the phone book.

However, if there is no such item, it does not mean that the feature is not available; often it is hidden deeper or requires region switching; in some MIUI builds for the global market, this option is removed completely due to strict privacy laws in Europe (GDPR), in which case it will not be possible to activate it systematically without changing the region.

⚠️ Warning: Automatically recording all incoming files can quickly fill the device's internal memory. Check the storage regularly or set up cleaning old files.

If you find the settings but the recording button doesn't appear during a conversation, check to see if the microphone is blocked for the system application. In modern versions of Android, access rights are strictly regulated, and any failure in the permissions can block the voice recorder.

Set up the region and the hidden capabilities of MIUI

One of the most effective ways to unlock functionality not available in your region is to change the region in your system settings.This is a secure procedure that does not require root rights and often returns features such as themes, widgets and, of course, call recording.

To do this, go to Settings of your Xiaomi Redmi Note 9, then select Additional and find Region. In the list of countries that opens, select India, Singapore or Russia. These regions have historically had more advanced functionality in standard Xiaomi applications.

Once you change region, the system may need to reboot or simply update the lists of available services. Go back to the Phone app and check the settings again. Often, after this manipulation, you can enable automatic recording or manual activation through the call menu.

• 🌏 Changes in region only affect system services and content, your personal data stays in place.
• 📞 The recording function can only appear after the device is fully restarted.
• ⚙️ Some features (e.g. Mi Pay) may become unavailable when selecting certain countries.
• 🔄 If changing the region didn’t help, try clearing the cache of the Phone app».

It is worth noting that in the latest versions of MIUI 12 and MIUI 13, the company began to actively hide these capabilities even when changing the region, in which case the system can ignore the choice of country or force the default settings to return after the update.

Use of third-party applications for recording

If the built-in tools failed to activate the feature, third-party developers come to the rescue. Google actively fights recording conversations in Android 10, 11 and higher, closing access to the microphone during a call to third-party applications.

One of the most popular and reliable applications is Call Recorder - ACR or TapeACall. When installing such programs on the Redmi Note 9, you must be prepared for the fact that the MIUI system will aggressively try to close the background process.

The process of setting up is usually this: once installed, the app will request access to contacts, microphone and phone, and then it will suggest calibrating the sound source, which is an important step, because choosing the wrong source will lead to you hearing only yourself and the other person not.

Settings → Applications → Application Management → [Your recorder] → Autostart (On) → Battery Savings (No Limits)

Some applications require the installation of a special plugin or even use of a plugin. ADB-This is a more complex method that requires connecting the smartphone to the computer, but it guarantees stable operation even on new versions of Android.

Solving problems with sound quality and lack of voice

The most common problem when recording calls on Android 10+ is the lack of voice in the file, due to changes in Google’s security policy that prohibit apps from intercepting audio streams during a conversation. On Xiaomi Redmi Note 9, this problem is solved by choosing the right sound source in the voice recorder settings.

In the recording app settings, look for Audio Source. Try to go through the options: Voice Call, Mic, Voice Communication. Each model and firmware version may have a different working source. Often, turning on the hands-free mode during a conversation helps, allowing the microphone to pick up the sound of the dynames.

It's also worth checking if the noise reduction mode is too high. Aggressive noise cancellation MIUI can treat the voice of the interlocutor as background noise and cut it out of the recording. Experiment with the equalizer settings or turn off the sound improvement in the Settings → Sound and vibration menu.

If nothing helps and the voice of the person remains quiet, try using a headset. Connecting wired headphones with a microphone often changes the path of the audio signal, which allows the recorder to correctly capture both sides of the conversation.

⚠️ Attention: Using hands-free to record reduces the privacy of the conversation, as you can be heard by others.

Where records are stored and how to manage them

Once you've successfully written files, you have to store them somewhere. Depending on the method you choose, the path to audio files may be different. For a built-in voice recorder, the standard way is a folder. MIUI/sound_recorder/call_rec internal storage.

Third-party applications often create their own directories in the root of memory or in the Android/data folder, and you can find them through the standard Explorer by sorting files by date of change. The file format is usually.m4a or.mp3, which ensures good compatibility with any player.

For easy record management, it is recommended to regularly transfer important files to the cloud or to the computer. MIUI has a built-in synchronization function with Mi Cloud, but the amount of free storage is limited. The alternative is to automatically download the folder with records to Google Drive or Yandex.Disk.

💡

Configure the file manager to display hidden files if you can't find the folder with the records. Sometimes the system directories are hidden by default.

Remember, audio files take up space. One minute of good quality conversation can take up from 0.5 to 1 MB of storage. When you use your phone actively, it can be hundreds of megabytes per month, which is critical for models with little internal storage.

Legal aspects and ethics of recording conversations

Before you start recording all your conversations, it is worth reading the legislation of your country. In the Russian Federation, recording your conversation for personal use is usually not prohibited if you are a participant in the conversation. However, publishing or transmitting such recording to third parties without the consent of the interlocutor may violate the law on personal data.

In other countries, such as some states in the US or the European Union, the laws may be much stricter, requiring the other party to be warned that the conversation is being recorded, and ignoring this rule can lead to serious legal consequences.

Use the record function responsibly. Keep your data confidential, especially if you record conversations with banks, government agencies or doctors. Don't transfer files with records over open channels without encryption.
