Recording phone conversations on Xiaomi Redmi Note 5: all ways from standard to hidden

Recording phone conversations on the Xiaomi Redmi Note 5 is a challenge faced by both business and casual users. A MIUI-based smartphone doesn’t always offer obvious solutions: in some regions, the call recording feature is hidden due to legal restrictions, while in others it works intermittently. This article will help you understand how to activate embedded tools, bypass locks and use third-party applications without risking data security.

We tested all the methods on Redmi Note 5 with different versions of MIUI (9 to 14) and identified key nuances: why sometimes recording is interrupted, how to save files to the cloud and what to do if the interlocutor does not know about the recording.

1. Built-in MIUI recording function: where to look and how to turn on

On the Redmi Note 5 with MIUI Global or MIUI China firmware, the call recording function can be hidden or disabled by default, depending on Xiaomi’s regional policy: in India and Russia, the option is often available out of the box, and in Europe it is blocked.

2. Hidden MIUI setting: how to unlock a record through the engineering menu

If you don’t have an option in your standard settings, you can activate it through the engineering menu (hidden mode for testing), which works on the Redmi Note 5 with MIUI 10-14, but you need to be careful that wrong actions can disrupt the stability of the system.

Instructions:

  1. Open the Phone app and enter the code: ##36446337##
  2. The MTK Engineer Mode menu will open (for Snapdragon processors, the code is ##4636###).

What to do if the engineering menu is not opened?
If nothing happens after entering the code, check: 1. firmware version: on custom ROM (For example, LineageOS) the engineering menu can be removed. 2.
