Recording phone conversations on the Xiaomi Redmi Note 9 is a useful feature that helps to capture important conversations, interviews or evidence. However, many users face the problem: where exactly are these files stored? Unlike photos or music, call records do not always lie in obvious folders, and their location depends on the firmware version, application settings and even the way they record.
In this article, we will look at all possible locations for recordings on the Redmi Note 9, including standard and hidden directories, and explain how to set up automatic saving and recover deleted files. We will focus on the differences between global (MIUI Global) and Chinese (MIUI China) firmware, as they affect the availability of the recording function.
If you've never turned on a conversation record or are unsure if it works on your device, check the settings first — it may be that the feature is just disabled. And for those who have recorded calls but can't find them, a detailed folder structure analysis and file manager search tips will help.
Important: some versions of MIUI may have their conversations blocked due to local laws (e.g. the EU or the US), and then you need a third-party app to tell you which ones are reliable and how to set them up properly.

Legal aspects of recording conversations: what you need to know
Recording telephone conversations is regulated by the laws of your country, and in most cases, recording conversations without the consent of the interlocutor is prohibited, except when:
- 📜 You are a participant in the conversation and use the recording for personal use (not for distribution).
- ⚖️ Recording is made in the framework of the trial (with the permission of the court).
- 🔒 The interlocutor is notified in advance of the recording (for example, at the beginning of the call, a voice message sounds).
In Russia, according to Article 23 of the Constitution of the Russian Federation and Article 138 of the Criminal Code, recording a conversation without the consent of the interlocutor can be considered as a violation of the secrecy of correspondence if the recording is used for distribution or blackmail. However, in the Civil Procedure Code (Article 55), such recordings are allowed as evidence if they are obtained by a lawful means.
In EU countries (e.g. Germany, France), the laws are stricter: recording a conversation without the consent of both participants can result in a fine; in the US, the rules vary by state: in some (e.g. California) the consent of all participants is required, in others (e.g. Texas) the consent of one is sufficient.
If you plan to use the records for official purposes (e.g. for a court), please specify the evidentiary requirements in advance, and in some cases, notarization of the file or expert opinion on its authenticity will be required.
