Recording conversations on Xiaomi Redmi 9: how to turn on and configure

Why You Need to Record Calls and What You Need to Know Before Setup

Recording phone conversations on Xiaomi Redmi 9 can be useful in dozens of situations, from fixing important business negotiations to preserving evidence for legal disputes. However, before you activate this feature, it is worth considering a few key points. First, the legality of recording conversations is regulated by the legislation of your country - in some regions you need to notify the interlocutor about recording. Second, built-in MIUI tools have limitations: for example, not all versions of the firmware support automatic recording of all calls without additional settings.

The Redmi 9 (M2003J15SC/M2004J19C) runs on MIUI 12-14, where the recording function is implemented via the Phone app. But here's a caveat: by default, the option can be hidden or disabled due to regional restrictions. If you don't find it on the menu, it doesn't mean your device doesn't "can't" record calls - it probably requires activation through Settings or installing updates.

Another important aspect is the storage of records. By default, files are stored in internal memory in a folder.

  3. If the version is older than 12.0.2, the feature should work. 11.x and below will require an update or third-party software.

Pay special attention to regional firmware. Chinese (CN) smartphones often have advanced recording features, whereas global (Global) or European (EEA) versions can be stripped down. If you don’t have a write option on your menu, try changing region via Settings β†’ Additional β†’ Region (but note that this may affect some services, such as Google Pay).
