How to set up autorecord calls on Xiaomi Poco X3: all ways + error solving

Recording phone conversations on Xiaomi Poco X3 is a useful feature for business negotiations, fixing important agreements or simply saving memorable conversations. However, standard MIUI settings do not always offer this option out of the box. Depending on the firmware version and regional restrictions, the path to activation may differ — or even be absent from the menu.

In this guide, we will look at all the working ways to enable auto-recording on the Poco X3 (including the Poco X3 NFC and Poco X3 Pro models), me, from formal settings to third-party workarounds. We will focus on file retention issues, recording quality settings, and legal nuances that many forget. If you have previously experienced recording interruptions or files not being saved, here you will find specific solutions.

Check Auto Recording Support in Your MIUI Version

Before you start setting up, it’s important to understand if your firmware version supports built-in call recording. Xiaomi regularly updates its privacy policy, and in some regions (e.g. EU countries) the feature may be disabled at the system level.

To check the availability of the option:

• 📱 Open the Phone app (the tube icon on the home screen).
• 🔍 Click on three dots in the upper right corner → Select Settings.
• 🎤 Scroll down to the Recording Conversations section (if not, your firmware doesn't support the "out of the box" feature").

If you don't have a Recording section, don't despair. In the next sections, we'll look at alternative methods, including hidden settings and third-party apps. In the meantime, remember that on MIUI 14+ and HyperOS firmware, built-in call recording can be blocked for models sold in Europe and the United States.

If your Poco X3 supports embedded recording, the activation algorithm is as follows:

1. Start the Phone → Settings app (three dots at the top).
