How to set up call recording on Xiaomi Note 10: Full Guide

Owners of the Xiaomi Mi Note 10 smartphone often face an unexpected obstacle: the built-in conversation recording feature may disappear or be unavailable immediately after purchasing the device.This is due to changes in Google’s policy, which since 2022 severely restricts third-party applications from accessing the microphone during a call.

However, there is a solution, and it doesn’t always require complex firmware manipulation. Depending on the region your smartphone’s software is based on, the built-in mechanism may simply be hidden. In this article, we’ll look at all the possible ways to activate the feature, from simple menu settings to the use of specialized applications that bypass Android’s system limitations.

We're going to look at the nuances of how the MIUI shell works and the new HyperOS, because the security algorithms are different. It's important to understand that the methods running on the global version may differ from the Chinese builds. So here are the general instructions adapted to different scenarios of your gadget.

Verification of the built-in function in a standard application

The first thing to start with is to check the standard Phone app thoroughly. In most cases, especially on devices designed for the CIS and Asian markets, the recording feature is already built into the system, but can be disabled by default or hidden in the depth of settings. You do not need to download anything if your region in the firmware allows this option to be used.

Open the call app and find the gear icon, which is usually located at the top of the screen. Go to the settings menu, look for Call Record. If you see this section, you're lucky that your device supports native recording without restrictions, and you can set up automatic recording of all incoming or outgoing calls.

⚠️ Note: If the phone settings menu is completely missing the item associated with recording conversations, then in your current firmware version (Global) ROM) This function is blocked at the system level due to the legal restrictions of the region.

Inside the recording settings menu, you can choose the format to save audio files. You can usually choose between MP3 and WAV formats. The former takes up less memory space, the latter provides higher audio quality, which can be critical if you plan to use the recording as proof or for transcription of text.

Also worth paying attention to is the recording notice. Many countries require that you alert the person that the conversation is being recorded. Xiaomi has an option to play a voice signal or voice message when you start recording. Ignoring this rule can have legal consequences, so it's best to leave the warning on.

• 📱 Open the phone application (green handset).
• ⚙️ Click on three dots or a gear in the corner of the screen.
• 🔍 Find the section "Recording calls».
• ✅ Activate the switch "Automatic recording».

💡

If you've turned on automatic recording, be sure to check for free memory. Audio files, especially in WAV format, can quickly fill up internal storage if you're communicating a lot.

Changing the region as a method of activating hidden functions

If the standard menu doesn't have the right item, the safest and most efficient way to return it is to temporarily change the region of the device. The logic of the MIUI shell is that the feature set depends on the selected country. In some regions, for example, in India, Indonesia or Russia (in certain builds), the recording function is allowed and built into the standard dialer.

To do this, you need to go to the basic settings of your smartphone, find the "Additional" or "Region" section, change the current value to "India" or "Indonesia," and then the system may require you to restart the interface or the device itself, which is the normal reaction of the operating system to change the geographic location.

When you change region, go back to the Phone app and check your settings again. Often, the item you want appears instantly. If it appears, you can set up a record and then, if you want, return the region back. However, be careful: region returns can sometimes (but not always) hide the settings menu again, even though the feature itself often continues to work.

It's important to understand that changing the region doesn't just affect the phonebook, it can change the list of recommended apps in the GetApps store, change the way the XiaoAI or Google Assistant works, and affect the display of news in the feed, so it's best to use this method as a temporary solution to activate the feature if other methods don't help.

Use of third-party applications for recording

When system constraints are too tight and region change doesn’t work, third-party apps come to the rescue. However, starting with Android 10 and up, Google has shut down direct access to the audio stream, which means that older apps that simply recorded sound from a microphone now often record the silence or sound of just your voice, ignoring the other person.

However, some applications have found workarounds, and one of the most reliable solutions right now is Appliqato’s Automatic Call Recorder app or NLL’s ACR app. These programs use special Accessibility modes or require ADB connectivity to gain advanced rights, allowing them to intercept the audio stream before it is blocked by the system.

When installing such software on the Xiaomi Note 10, be prepared for the MIUI security system to aggressively try to shut down the application to save energy. You will have to manually prevent the system from "killing" the recording process. This is done through the Applications menu → Permissions → Auto Start and battery settings.

⚠️ Warning: Third-party apps may not work well after Android security updates. If the record stopped working after the system update, try reinstalling the app or resetting its permissions.

Another option is to use applications that create conferencing, which add a third person to the conversation, a bot recorder that records everything that happens in the conference, and the downside is that both people hear the horn of the connection, and it can be a paid service from your carrier.

• 📥 Download the Call Recorder app - ACR Play Market.
• 🔓 Provide all requested permissions, including access to the microphone.
• ⚙️ In the application settings, select the sound source “Voice Call” or “Mic».
• 🧪 Make a test call to a friend to check the quality of the recording.

Configuring sound sources and microphone

The quality of the recording on Xiaomi Note 10 depends on the right choice of sound source. In the settings of both the built-in recorder and third-party applications, you can often choose where to get the audio stream. The wrong choice will lead to the fact that you get a file that only you can hear, or, conversely, only network noise.

The best choice for modern versions of Android is the source of Voice Call or Voice Communication. If this option is not available, try Microsoft. In the latter case, it is important during a conversation not to close the palm of the lower part of the screen where the main microphone is located, and not to put the phone with the speaker on soft surfaces.

If you use a headset or Bluetooth headphones, the logic of the recording may change, and some applications can't capture the sound from Bluetooth devices and continue to write from the main microphone of the phone, which gives an echo effect, in such cases, it's better to switch to speakerphone so that the microphone accurately captures the voice of the interlocutor through the speaker.

In advanced recorder settings, you can find a Gain or microphone amplification, and if the voice is very quiet, you can try to increase this parameter, but be careful: excessive amplification will add a lot of digital noise and hiss, making the recording unusable for listening.

💡

For best echo-free quality, use the "Loud Communication" mode in combination with the sound source "Microphone" if direct stream capture is not possible.

Where are the records stored and how to find them

Once you've set up successfully, it's important to know where files are saved so you don't lose important information. In MIUI, the file path is standard and usually doesn't change, which makes it easier to find them, and you can find them through standard Explorer or through the Dictator/Call Recorder app.

Physically, the files are located in the root directory of internal memory: MIUI/sound_recorder/call_rec. If you connect your phone to your computer through USB-cable, you can easily copy these folders to your hard drive for archiving.

In the file manager of the smartphone, the path can be displayed slightly differently, for example: Internal shared drive → MIUI → sound_recorder → call_rec. Here, files are usually sorted by date and time of the call, making it easier to find the right conversation. The naming format often contains the phone number and date in the format of the GGMDD Time.

Remember that audio files take up space. If you record all calls actively, memory can run out unexpectedly. It is recommended to transfer archives once a month to the cloud storage (Google Drive) or to the computer, making room for new photos and applications.

• 📂 Open the "Conductor" application».
• 📁 Go to the folder. MIUI.
• 🎙️ Open the folder. sound_recorder, later call_rec.
• 📤 Copy files to save on PC.

Frequent problems and their solution

Even with the right setup, users can encounter errors. The most common problem is that the recording is interrupted after a few seconds or the silence is recorded, which is almost always due to the fact that the Android system forcibly completes the recording process in the background.

To fix this, you need to find the installed application to write in the list of applications, go to "Battery Consumption" and select "No Limits" mode. Also in the "Permissions" menu, you must necessarily allow "Return." Without this, the MIUI optimizer will "kill" the recorder immediately after you put the phone down.

Another problem is that there's no audio on the other side of the Bluetooth headset, and unfortunately, that's a technical limitation of many smartphones, because they don't allow you to stream audio to both the record and the Bluetooth device in full duplex, and the solution is that during the important conversations you need to record, use a phone speaker or a wired headset.

⚠️ Note: When using a wired headset, make sure it is fully compatible with your phone's connector.The Xiaomi Note 10 may require a 3.5mm Type-C adapter, and not all adapters support microphone input.

If nothing works, and the built-in feature doesn’t appear and third-party doesn’t work, the radical method remains – flashing the device to the Chinese version of the software (China ROM) and then installing Google’s global languages and services. This is a complex process that requires unlocking the bootloader, and it is not recommended for ordinary users, as it can lead to loss of warranty or “bricking” the device if an error occurs.

Legal aspects and ethics of recording

Using the recording function, you should be aware of legal responsibility. In the Russian Federation, recording your own conversation for personal needs is not prohibited, however, using this recording in court or publishing it in the public domain without the consent of the other party may violate the law on personal data and privacy.

Some countries (e.g., some states in the U.S. or Germany) have a two-party consent principle, which means that both parties must agree to the recording, and that violation of this rule can result in serious fines, so always use the entry warning feature built into MIUI.

Corporate ethics also dictates its rules, recording conversations with customers or colleagues without notice can be considered a violation of an employment contract or trade secret, and always check your company's internal regulations before turning on the recorder.
