Owners of Xiaomi smartphones and the Poco sub-brand often face the need to quickly find and play back saved dialogue. The Poco X3 Pro model has powerful hardware, but the MIUI software shell has its own features of navigating system files. The standard search algorithm may not be obvious for those who use an automatic call recorder for the first time.
The main challenge is that Android tightens security policies every year, limiting direct access to records from third-party file managers. However, the built-in MIUI makes it easy to manage audio without having to get root rights. You don't have to search for hidden folders manually if you know the right path through the system application.
In this guide, we will go into detail all the available ways to play audio archives, we will look at both standard methods through the “caller” and working with the file manager for advanced users, and we will pay special attention to quality settings, since they depend on the readability of stored information.
⚠️ Note: Recording telephone conversations without warning may violate the laws of your country. Use this feature only for personal purposes or with the consent of the other party.
Using the built-in Phone application for playback
The easiest and most reliable way to listen to the saved dialogue is to use the standard Phone app, which is preinstalled on the Poco X3 Pro. This is where the system automatically sorts incoming and outgoing calls, marking those that were recorded, which saves the user from having to dig into the system directories.
To start, open the Phone app and go to the History or Recent tab, find the contact or number you want on the list, and if you've made a successful entry, you'll see a tape or red dot icon next to the phone number or name, and if you click on the call card, you'll see the play button right in the dialing interface.
The player interface in MIUI is quite functional, and it allows you not only to listen to the audio, but also to rewind it, pause it, or speed up playback, which is especially useful when you need to quickly find a specific phrase in a long conversation, and the files are saved in high quality, unless you choose otherwise in the settings.
- 📞 Open the Phone app and go to the Call History tab.
- 🔍 Find the right number by paying attention to the icon of the recorder next to it.
- ▶️ Click on the play icon or select the call card to open details.
- ⚙️ Use the slider to rewind and the speaker button to output sound.
⚠️ Note: If the record icon is not in the history, then the automatic recording function was disabled at the time of the call or the device did not have enough free memory.
It's important to note that when you delete your call history from the caller registry, the audio files themselves may remain in the device's memory, but it will become more difficult to find them without a contact link, so cleaning the call log requires caution if you plan to keep the files for a long time.
Search for records files through file manager
If your standard call history has been cleared or you need to copy a file to your computer, you'll have to go to the file system. Poco X3 Pro uses a MIUI file manager that has access to system folders. The path to records is strictly defined by the Android architecture, but can vary depending on the firmware version.
Open the Explorer app or Files app, and you need to go to the internal storage, and the path to the records is usually as follows: MIUI → sound_recorder → call_rec. It's in this directory that all audio files, sorted by date of creation, are stored.m4a or.mp3, This ensures compatibility with most players.
You can use file search to get access quickly, type in the file manager's search box the.m4a extension or the call keyword, and the system will instantly filter out the extra and show you only the audio you want, which is especially useful if you have hundreds of files in your phone's memory.
/storage/emulated/0/MIUI/sound_recorder/call_rec/When working with files manually, be careful when renaming. Changing the file name can break the binding in the call log, and the voice recorder icon in the caller will disappear, although the file itself will remain operational. The MIUI system indexer updates the database only when the device is new or rebooted.
- 📂 Launch the Explorer app on your Poco.
- 📁 Going the Way: Internal Memory → MIUI → sound_recorder → call_rec.
- 🔎 Use search for extension.m4a file-filter.
- 🎧 Click on the file to open it with the built-in player.
💡
To quickly find the record file in Explorer, sort the files by date of change – the most recent records will always be at the top of the list.
Configuring automatic recording parameters
To avoid missing an important conversation, you should set up the recording function in advance. Xiaomi Poco X3 Pro has a flexible rule system, you can record all calls automatically or select specific numbers from the contact book, which saves space in memory and not record unnecessary conversations with couriers or spam.
To set up, go to the Phone app, click on the three dots in the top corner and select Settings. Then look for Call Record. Here activate the "Write Automatic" slider. Below you can select "All Numbers" or "Selected Numbers." In the second case, you will open a contact list where you need to check boxes against the right people.
The record quality is particularly noteworthy. In the same settings menu, find the item "Record quality." The default may be "Regular", but for the Poco X3 Pro with its high-quality microphone module, you'd better choose "High", which will increase the file size, but make speech more legible, which is critical when listening in noisy environments.
| Parameter | Description | Recommendation |
|---|---|---|
| Sound source | Choosing a microphone | Microphone (main) |
| Quality. | Bitrate audio | High (for important negotiations) |
| Format | Type of compression | M4A (Quality and Size Balance) |
| Notification | Recording sound | Insert (for etiquette) |
Be sure to check for a recording notification. In some regions and versions of MIUI, the system automatically alerts the interlocutor with an audible signal. It is software difficult to turn off this, because it is a security requirement of Android.
☑️ Checking the recording settings
Working with cloud storage and synchronization
Conversation records take up space in internal memory, which on the Poco X3 Pro is not expanded by memory cards. To avoid losing important data when you reset your settings or break your smartphone, use cloud synchronization. Xiaomi Cloud allows you to reserve recordings of the recorder, including phone conversations.
To activate, go to Settings on your smartphone, select your Mi Account and click on Xiaomi Cloud. Make sure the sync for Dictator is enabled. After that, all new recordings will automatically upload to the cloud, and you can listen to them not only from your phone, but also through the i.mi.com web interface from any computer.
However, the limits of free storage should be considered. Xiaomi standardly provides 5 GB, which is divided between photos, system backups and records. If you are actively recording conversations, the space will run out quickly, in which case consider buying additional volume or regularly exporting files to an external hard drive.
⚠️ Warning: When you reset your phone to factory settings without prior synchronization, all local records will be permanently lost. Always check the status of the cloud before formatting.
An alternative is to synchronize the folder. call_rec with third-party services like Google Drive or Dropbox if you use synchronization apps, this requires more complex initial setup, but gives you more control over files.
What if the cloud doesn’t sync records?
Solving Common Reproduction Problems
Poco X3 Pro users sometimes face a situation where a record is made but cannot be reproduced; the file may be corrupted, not read by the player, or simply not appear in the list; often the problem lies in codec conflict or file system errors after the phone is not properly shut down.
If the built-in player is not able to open the file, try opening it through a third-party application, such as VLC for Android. This player supports almost all audio formats and codecs. If the VLC can't open the file, it's likely that the recording was interrupted at the time of saving due to lack of space or battery discharge, and the file is physically damaged.
Another common problem is the quiet sound of the interlocutor, which is due to the noise cancellation features of the Poco X3 Pro. The microphone can “stuff” the voice of the interlocutor with street noise. In the recording settings, try changing the source of the sound if this option is available in your version of the firmware, or use the headset during important conversations for better speech capture.
- 🔇 Update the Phone and Recorder app through GetApps store or Google Play.
- 🗑️ Clear the cache of the phone application in the application settings.
- 🔊 Check the volume of the multimedia, not just the volume of the call.
- 🔄 Restart the device to restart the system’s audio services.
In rare cases, the problem may be access rights. Make sure the Phone app is allowed to work with microphone and memory. Go to Settings → Apps → Phone → Permissions and check all points. Lack of access to memory will not save the file, and the microphone will record silence.
💡
If a file is corrupted, it's almost impossible to restore it, because the audio stream has not been properly closed by the metadata.
