There are several ways to activate this option, ranging from standard settings for the Phone app to third-party solutions. Conversations can be recorded automatically for all incomings, and can be manually triggered as needed. It is important to understand the differences in how this feature works across different versions of the Android operating system, as Google's privacy policies are constantly changing.
In this article, we will take a closer look at the algorithms for turning on a record, where files are saved, and how to circumvent system constraints, learn how to set up automatic recording for specific numbers, and understand why in some cases the interlocutor hears a voice alert, this guide will help you always have an audio archive of important conversations at hand.
Standard recording function in the phone application
Most Xiaomi, Redmi and Poco models have a built-in recording module integrated into the standard call. To activate this feature, you need to go to the settings of the application itself, not the general system. Open the Phone app, click on the gear icon or three dots in the corner of the screen to get into the settings menu. Here you will find the Call Record section, which is key to managing audio recordings.
Inside this menu, you have an Autostart Recording switch that allows you to archive without you being involved with each call, and if you only need to record a specific conversation, you'll see a button on the screen that shows a cassette or microphone, and you'll click on it and start the process, as shown by the timer on the screen and the characteristic beep.
⚠️ Note: When recording is enabled, the interlocutor can hear a voice message “Conversation recording has begun”, if this is provided for by regional laws or your SIM card settings.
Some users prefer to choose “Write only certain numbers” mode, which is a useful feature for controlling communication with specific contacts, such as delivery services or customers, and allows you to flexibly customize rules, eliminating personal conversations from the general archive.
💡
To quickly activate the recording during a conversation, you can use the application sidebar, adding a voice recorder shortcut there if the standard button is not displayed.
Automatic recording for all calls
Automating the process is the most convenient way to keep a single detail of an important conversation in mind. To set up an automatic record of all incoming and outgoing calls, you should go back to the settings menu of the Phone application. Find the Call Record and activate the Autostart Record switch, and then the system will start saving each conversation without additional actions on your part.
It is important to consider that when you turn on this option, the phone can take up more space in internal memory. Files accumulate quickly, especially if you communicate a lot. It is recommended to periodically check the folder with records and delete unnecessary or transfer data to the cloud storage Mi Cloud or Google Drive.
- 📱 Open the Phone app and go to settings.
- 🎙️ Select Call Record in the Options List.
- ✅ Activate Autostart Recording Switch.
- 📂 Check the way to save files in the same settings menu.

Why the recording button on new versions of MIUI is missing
Many users have experienced a situation where the recording button has disappeared or become inactive after updating the firmware, due to changes in Google’s security policies and local laws in the countries where the device is sold. In some regions, such as the European Union, the recording function of conversations can be software blocked at the system level.
If you upgraded to MIUI 14 or HyperOS and lost functionality, try changing the region in your phone settings. Go to Settings → Additional → Region and select a country where recording is allowed, such as India or Singapore. Once the device is restarted, the feature often returns.
⚠️ Warning: Changing the region may affect the performance of some local services and displaying ads in system applications, so after turning on the record, the region can be returned back, but the function may be disabled again.
Another reason for the lack of a feature may be the use of a third-party application for calls instead of a system one. Google Phone (Google Dialer), which is often pre-installed on global versions, has its limitations. It is possible to record it, but with a mandatory voice notification of the interlocutor, which cannot be disabled by standard means.

Use of third-party applications for recording
When embedded tools don't work or work, third-party apps from Google Play come to the rescue. One of the most popular solutions is Call Recorder's ACR or TapeACall, which allows you to bypass some system limitations and offer more flexible audio quality settings.
However, installing such programs on Android 10 and higher is difficult, restricting third-party applications from accessing the microphone during a call in the background. ADB-teams to grant extended rights.
| Annex | Pluses | Cons |
|---|---|---|
| Call Recorder - ACR | High quality, cloud support | Requires complex setup on new Android |
| TapeACall | Easy to use, recording through a conference | Paid subscription, reduced sound quality |
| Cube ACR | Recording messengers (WhatsApp, Telegram) | Unstable performance on some models |
When using third-party software, it is important to carefully read the permissions that the program requests. Some of them may transfer your data to their servers. Always choose proven applications with high ratings and a lot of reviews.
Where are the records of conversations stored and how to find them
By default, all audio recordings are stored in the device's internal memory in a dedicated directory, and you can find them through a standard File Explorer: MIUI → sound_recorder → call_rec. Files are sorted by date and time of creation.
You can also access records directly through the Dictaphone or Phone app, and the call app often has a separate tab or a Record History button where you can listen to the file without going to the file system, which is convenient for quickly finding the right conversation by contact.
- 📂 Open the Files app on the desktop.
- 📁 Go to the folder. MIUI, later sound_recorder.
- 🎵 Open the folder. call_rec file-access.
- 🔍 Search by date or contact name.
If you sync with Mi Cloud, records can automatically be uploaded to the cloud when you connect to Wi-Fi. This will save your data in the event of loss or breakage of your smartphone. Check your sync settings in the Settings menu → Mi Account → Cloud.
💡
Regular backup of conversation records to your computer or the cloud is the only way to ensure that they are safe in the long run.
Solution: quiet sound and interruptions
One of the common problems is the very quiet sound of the recording, when the interlocutor is barely audible and your voice sounds loud, which is due to the noise cancellation and sound processing algorithms in Xiaomi. To improve this, try not to close the bottom of the screen where the microphone is located during a conversation, or turn off the noise cancellation in the sound settings, if this option is available.
Sometimes recording can be interrupted due to a lack of RAM or aggressive battery optimization, the system can "kill" the recording process, considering it a background task. To prevent this, go to the battery settings, find the Phone or Recorder application and select Unlimited mode.
If the problem persists, try clearing the Phone app cache. Accumulated temporary files may cause the recording module to malfunction. Go to Settings → Apps → All Apps, find the Phone and click Clear → Clear the cache.
Legal aspects and ethics of recording conversations
Using the record function, it is important to be aware of your country's laws. In some countries, recording a conversation without warning is illegal and may entail legal liability. Always check local laws before starting to massively archive the negotiations.
Ethically, it is a good idea to warn the person that the conversation is being recorded, which creates an atmosphere of trust and transparency, especially in business communication, and Xiaomi’s built-in systems often automatically warn about this, which is the right approach.
Do not use the recordings to blackmail or publish publicly without the consent of the participants in the dialogue. Personal correspondence and conversations are protected by the right to privacy. Recording a conversation on Xiaomi is technically possible, but its use must remain in the legal field.
