Recording phone conversations on Xiaomi Redmi 9C: a complete guide with nuances

Xiaomi Redmi 9C is a budget smartphone with limited built-in call recording features. But that doesn’t mean owners will have to put up with the lack of such a capability. In this article, we will examine all the working methods, from hidden MIUI settings to third-party applications with automatic dialog saving. We will focus on the legal aspects: in which cases recording a conversation can become evidence in court, and when using it is fraught with a fine.

It's important to understand that the Redmi 9C's built-in call recording feature is missing because of the limitations of MIUI 12's firmware for budget models. But there are workarounds -- and we've tested them in practice. In this article, you'll find not only instructions, but also a comparison table of methods for reliability, sound quality and legality, and at the end, answers to frequent questions, including "how to recover a randomly deleted record" and "can I record calls via a Bluetooth headset?"

Why is Redmi 9C not using a built-in call record?

The reason lies in the hardware and software limitations of the budget line of Redmi. Unlike flagships (for example, Xiaomi 13 Pro), where call recording is implemented at the firmware level, entry-level models save on:

• 🔊 Cheap microphones can’t record voices from both sides at the same time.
• 📱 Processor: Helio G35 redmi 9C Not optimized for background sound processing during a call.
• 📜 Licenses: Xiaomi does not pay for patented recording technologies (such as Dolby) to make the device cheaper.

In addition, in some countries (for example, in the EU), recording calls without notifying the interlocutor is prohibited by law, so Xiaomi removes this feature from the firmware for certain regions. Even if you find “secret codes” on the network to activate the recording (for example, # # # #6484##), they will not work on the Redmi 9C, as confirmed by tests on MIUI 12.0.8 and MIUI 12.5.3.

⚠️ Attention: Use of the “left» APK-Files to unlock hidden functions can lead to blocking IMEI In 2023, Xiaomi tightened its policy on modified firmware, which means that the smartphone may stop passing the Mi Account check during repairs.

The safest and most legal method is to use the built-in Google Drive feature, which works on all Android 9+ smartphones, including the Redmi 9C, but requires pre-configuration.

Method 3: Hidden recording via second phone

If you want 100% reliability (for example, for litigation), the best option is to record a conversation on a second phone next to you, and this method works even if:

• 📵 On the Redmi. 9C battery discharge.
• 🔇 The interlocutor blocks the recording (some operators, for example, MTS, send a signal to ban the recording).
• 🛡️ You are afraid that the application “merges” data.

How to record a conversation correctly:

1. Put a second phone (like an old iPhone or Samsung) next to the Redmi 9C.
2. Turn on the recorder (in iOS: App Voice Notes, in Android: Voice Recorder from Google).
3. Activate speakerphone on Redmi 9C so both voices are recorded clearly.
4. After the conversation, save the file to the cloud (for example, iCloud or Yandex.Disk).

Advantages of the method:

• 🎙️ Best sound quality (no compression like in apps).
• 🔒 Unable to detect (the interviewee will not know about the record).
• 📁 Files are saved in the original format (.m4a or wav).

💡

To improve the recording quality, put the second phone in a small box – this will reduce echoes and extraneous noises.

Method 4: Recording via Bluetooth headset (hidden mode)

1. Connect the headset to the Redmi 9C via Bluetooth.
2. In the headset settings (if there is an accompanying application) enable the Call Recording option.

Method 5: Rooting and Modified Firmware (for Advanced)
