Owners of the popular Xiaomi Redmi Note 9 smartphone often face an unexpected limitation: the standard feature of recording conversations may be absent in the usual place or work incorrectly. This is due to changes in the security policy of the Android operating system that Google implements in recent versions, as well as regional features of the MIUI firmware. Users who have upgraded to the latest versions of the shell sometimes find that the recording button has disappeared from the call interface, which creates serious inconvenience for those who are accustomed to fixing important agreements.
However, the situation is not critical, and there are several proven ways to return this feature: depending on the installed version of the firmware (Global, European or Chinese) and the region, the methods may differ. In some cases, it is enough to simply change the region in the settings, in others, you will need to activate hidden functions through the engineering menu or use third-party solutions.
Remember, recording phone conversations is a legally sensitive function, and many countries require that the conversation is notified that the conversation is being recorded. Redmi Note 9 often has a distinctive beep or voice alert that the other party hears when the recording is on, and ignoring this can have legal consequences, so use the tool responsibly.
Checking the standard settings of the call
Before you resort to complex manipulations, you need to make sure that the feature is really hidden or disabled, not just not activated in the menu.In Google's standard Phone app, which is installed on most global versions of Redmi Note 9, settings may not be in sight. Open the call app and click on the three dots in the upper right corner of the screen to enter the settings menu.
If you have a call record, you're lucky enough to switch the switch to the active position, you can set up automatic recording of all calls that are coming and going, or only for certain numbers, and you can automatically record the call recorder, and you can manually press the button when you're talking, which is especially convenient in a hurry.
⚠️ Note: If the call settings menu is completely missing Call Record, it means that your current firmware version or region does not support native function via the standard interface.
The interface of settings can vary depending on the version of MIUI. On some devices, the path looks like Settings → System Applications → Phone → Recording calls. Make sure you check both menu layouts. Also pay attention to the file saving format: usually MP3 or AAC, and choose a folder to store them in internal memory.
Replacement of the region to activate the function
One of the easiest and safest ways to recover a missing record button is to change the region in the system settings. Xiaomi often links the functionality of a standard call to the user's geographic location. In some countries (for example, India or Indonesia), recording conversations is legally allowed and enabled by default, while in Europe there are more stringent GDPR rules.
To implement this method, go to Settings → Additional settings → Region. From the list of countries, select India, Indonesia or Singapore. After changing the region, the phone interface may change slightly, new widgets or news will appear, but most importantly, the call settings should be able to record. Reboot the device after changing the region is usually not required, changes are applied instantly.
It's worth noting that the region change affects not only the phone book, but also some system applications, such as Explorer or Music, where the set of available content can change. However, for the main task of recording conversations, this method is the most effective and does not require installing third-party software. If the function appears after the region change, you can use it indefinitely.
This is normal for a given location. Functionally, the record will work stably, saving files to a standard folder. MIUI/sound_recorder/call_rec.
Use of third-party applications for recording
If the region change didn’t help or you don’t want to change your system settings, Google Play apps will come to the rescue. Due to the limitations of Android 10, 11, 12 and later, regular apps don’t have direct access to the audio stream. However, there are specialized solutions that use Accessibility Service to bypass these restrictions.
One of the most popular and reliable solutions is the Call Recorder app - Cube ACR. Once installed, it will request a number of permissions, including access to a microphone, phone and, critically, "Special features." All requests must be resolved, otherwise the program will not be able to intercept sound. In the application settings, it is recommended to choose the source of the sound "Voice Call" or "Mic" if the first one does not work.
- 📱 Cube ACR — market leader, supports recording via VoIP (Viber, WhatsApp, Telegram), has flexible quality settings and cloud backup.
- 🎙️ Automatic Call Recorder is a simple app from Appliqato that automatically records all incoming and outgoing calls, can mark important records.
- 🔒 Blackbox Call Recorder – minimalist design, no advertising in the basic version, support for recording in high quality and sorting by contacts.
⚠️ Note: When using third-party apps, recording quality may depend on the phone model and Android version. On some devices, the sound of the interlocutor may be quiet or absent if the speaker is not turned on.
To keep these programs running smoothly on the Redmi Note 9, you need to add them to the power saving exception list. Go to Settings → Battery and Performance → Search for applications, find the installed recorder and select No Limits mode. It is also worth fixing the application in memory (lock in the menu of running applications) so that the system does not unload its process.
Configure automatic recording and formats
Once the recording function is activated, whether native or via the app, it is important to set up the save settings correctly. Quality recording takes up more space but provides better speech legibility. In a standard Xiaomi call, you can choose the encoding format. AMR (smaller size, lower quality) and AAC or MP3 (best quality) are usually available.
Automating the process is key to making it comfortable, so you can set up a record of all numbers, just contacts from the phone book, or by eliminating certain numbers, and in the record settings menu, find Auto Record and activate the options you need, so you don't have to risk forgetting to press a button during an important conversation with a customer or government official.
☑️ Set up the perfect recording
Remember to check the records folder periodically. Files can accumulate and take up a significant amount of internal memory Redmi Note 9. It is recommended once a week to listen to the archive and delete unnecessary or transfer important files to your computer or cloud storage. Some applications allow you to set up automatic cleaning of old records when the place is over.

| Alarming | Included (by law) | Legal security |
Solving quality and lack of sound problems
A common problem with Redmi Note 9 users is that they're recording, but they're not listening. It's about how Android handles audio. If you're using a third-party app, try changing the Audio Source settings. Go through the options: Default, Mic, Voice Call, Voice Uplink. Often, it's the Voice Uplink or Voice Downlink that solves the problem.
Another reason for quiet noise can be an active noise suppressor, and in some cases, turning on the speakerphone while you're talking helps if you're in a quiet room, and also check if the microphone is covered with a cover or dirt. For native recording, Xiaomi sometimes helps to clean the cache of the Phone application through the Settings menu. → Annexes → All applications → Phone. → Clear the cache.
Why can the recording be interrupted?
If you use a headset or Bluetooth headphones, the recording quality may change. Some audio protocols do not support simultaneous recording of the internal audio stream. In such cases, the system can switch to recording through the phone's microphone, which will cause an echo. For critical conversations, it is better to use a phone speaker or a built-in microphone.
Legal aspects and data storage
The use of the telephone recording function is regulated by the legislation of your country. In the Russian Federation, according to Art. 24 of the Constitution and Federal Law "On Communications", recording a conversation without warning the interlocutor can be regarded as a violation of the right to secrecy of correspondence and telephone conversations.
In the business environment, the situation is stricter: operators are required to warn customers about the recording. Xiaomi’s native feature often plays the beep (“Recording has begun”) that the interlocutor hears. This is a sufficient warning in most jurisdictions. Third-party applications may not have such a signal, which creates legal risks when using the recording in court.

Keep important records on external media. Your smartphone's internal memory can go down, and cloud services sometimes block access. Regular backup is key to keeping your data safe.
The best way to store files is to create folders by month or project. Record files have metadata with date and time, but manual sorting will speed up your search. Remember, when you reset your phone to Hard Reset, all local records will be permanently deleted unless you back up in advance.
💡
Native recording on Xiaomi Redmi Note 9 is the most stable method, but requires proper region setting. Third-party apps are a good alternative, but require careful setting of access rights.
