Recording phone conversations on the Xiaomi Redmi Note 9 may be necessary to store important information, record agreements or evidence in controversial situations. However, standard MIUI capabilities are limited: in some regions, the call recording function is disabled due to legal regulations. In this article, we will discuss all working methods, from embedded tools to third-party applications, including bypassing restrictions without root rights.
It is important to understand that the legality of recording conversations depends on the legislation of your country, and in most cases, you need to notify the interlocutor about the recording, and we do not recommend using these methods to covertly collect information without the consent of the participants in the conversation.
Technically, the Redmi Note 9 (M2003J15SC/M2003J15SS) supports firmware call recording, but the feature can be hidden. Below are the current ways for MIUI versions 12, 13 and 14 (including global and Chinese builds).
1. Built-in call recording in MIUI: where to look and how to turn on
On some Redmi Note 9 firmware, the call recording feature is available by default, but hidden in the menu depth.

Put a second smartphone next to you with the recorder on, and it's reliable, but it requires an extra device, and it can degrade the sound quality because of the echo.
