How to record a conversation with Xiaomi Redmi 9A

The Redmi 9A series remains one of the most popular budget devices, but their software often raises questions among users, especially the voice recorder function during calls, which in the latest versions of the MIUI shell and pure Android is often hidden or modified. Recording a conversation on Xiaomi 9A can be implemented by regular means of the system or through third-party solutions, but each method has its own nuances.

Device owners are facing a situation where the familiar Write button disappears from the call interface, due to changes in Google’s privacy policy that tightly regulate app access to the microphone during voice calls. However, the Xiaomi Redmi 9A has enough performance and functionality to ensure that important dialogs are saved if the system is configured correctly.

In this guide, we will look at all the current ways to capture audio, from built-in tools to specialized software, you will learn how to get around the limitations of the operating system and where to look for saved files after a call is completed, and understanding these mechanisms will allow you to not miss any important detail in communication.

Features of recording calls on MIUI and Android

The main challenge faced by Redmi 9A users is the operating system version. If your device runs Android 10 and higher with a MIUI 12 shell or later, it is likely that Google Phone has a standard call installed. Unlike the old MIUI Dialer app, which had a built-in and simple voice recorder, the new software requires additional permissions.

Google Dialer’s regular recording mechanism works, but often warns the interlocutor with a voice signal that the conversation is being recorded, a requirement of many countries’ laws that Google implements at the system level, but on some regional Xiaomi firmware, this voice assistant may not be available, which makes the recording hidden.

⚠️ Note: Recording a conversation without warning the person may violate your country's laws and use this feature only for personal purposes or with the consent of the other party.

It is important to distinguish between two types of recording: one-way (only you can hear it) and two-way (both people can hear it), and standard tools tend to be two-way, but Android's technical limitations often result in the voice being recorded very quietly or not at all.

💡

If the voice of the interlocutor is barely audible, when recording through the speaker, bring the top of the phone (where the main microphone is located) closer to the ear, but do not press tightly so as not to block the sound.

Use of the built-in voice recorder in the Phone application

The first thing you need to check for the owner of Xiaomi Redmi 9A is the presence of a built-in feature in the current firmware version. Even in new shells, Xiaomi sometimes leaves the ability to activate recording through call settings. To do this, open the Phone application and go to the settings menu, which is usually hidden under three dots or a gear.

In the menu that opens, find Call Record. If you have one, you can have flexible settings, you can enable automatic recording for all incoming and outgoing calls, or select specific numbers from the contact book, which is the most stable method, and does not require additional software.

• 📱 Automatic Recording: Allows you to save all incoming calls without your involvement.
• 📞 Recording of selected numbers: activates the recorder only when calls from certain contacts.
• 🔊 Audible notification: an option that plays the click sound when recording begins (you can turn it off in some versions).

If there is no record point in the Phone app settings, it means that your regional firmware version uses strict Google policies, in which case the system blocks access to the audio stream. Trying to enable recording through hidden codes or engineering menus on modern versions of Android often fails or leads to unstable system operation.

Automatic recording for all numbers

For those who have found the recording function in the settings, the correct configuration of parameters is critical. Automating the process eliminates the need to manually press the recording button every time you talk, which is especially useful when you have an important dialogue or when your hands are busy.

Go to Call Settings → Call Recording. Auto Recording is the key to activate the switch. After you turn on, you can select to record all calls or only unknown numbers. The latter option is useful for recording calls from delivery services, banks or scammers.

Activation path:


Phone → Settings (three dots) → Recording calls → Autosave

Note that automatic recording consumes free storage space quickly. Files are saved in.m4a or.mp3 format and take anywhere from 500 KB to several megabytes per minute, depending on the quality of communication and the duration of the conversation. Regularly check the folder with the records and delete the unnecessary.

Third-party applications for recording conversations

If Xiaomi 9A doesn’t record a conversation with its regular tools, third-party apps come to the rescue, but due to the limitations of Android 10-14, most of them work incorrectly: they only record your voice or silence, but there are solutions that can circumvent these restrictions.

One of the most effective solutions is to use audio source-change applications that can use accessibility service to activate the hands-free communication during a call, allowing the microphone to capture the speaker's sound. Popular programs include Cube ACR, Automatic Call Recorder, and other analogues.

When installing such software, be sure to provide all the requested permissions, including access to the microphone, phone and, importantly, Special. features. Without activating a special plugin (App Connector) in the Android availability settings, the application will not be able to intercept the audio stream during the call.

Problems with sound quality and their solution

A common problem with recording on Redmi 9A is the low volume of the voice of the interlocutor, which is because the smartphone's noise-cancelling system can perceive the voice from the speaker as background noise and try to drown it out, resulting in a recording that is intermittent or quiet.

To improve quality, try changing the recording source in the settings of a third-party app. If you have a choice between Microphone and Voice Call, experiment with both options. In some cases, it helps to turn on speakerphone automatically when you start recording, although this is not always convenient in public places.

⚠️ Attention: Using hands-free during recording can cause echoes if the room is poor in acoustics. Try to be quiet for clean audio.

Also, quality is affected by the network operator and the type of communication (2G/3G/4G/VoLTE). When a voice compression codec is bad, it is more aggressive, which reduces the intelligibility of speech in the recorded file. Make sure that you have a confident reception of the signal at the time of an important conversation.

💡

The best recording quality is achieved by using a wired headset or Bluetooth headphones, as they have their own microphones and speakers, sharing the sound streams.

Where to look and how to manage recorded files

Once the call is complete, the file is stored in the device's internal memory, and the path to it depends on the recording method used. For a regular Xiaomi voice recorder, files usually lie along the path. MIUI/sound_recorder/call_rec Or in the Record folder at the root of the vault.

If you've used a third-party app, look for a folder with the program name at the root of internal memory or in the Android/data section. You can listen to the recording directly in the Dictator app or through any standard audio player. Files have timestamps, which makes it easier to sort.

To free up space, it is recommended to periodically transfer the archives of conversations to your computer or to the cloud storage. In the settings of the recording application, you can often specify a cloud service (Google Drive, Dropbox) to automatically upload new files immediately after the call is completed.

• 📂 The Standard Way: Internal Memory → MIUI → sound_recorder → call_rec.
• 🔍 Search: Use file manager and sort by date of change.
• ☁️ Backup: Set up synchronization of the record folder with the cloud.
