Where are the Call recordings stored on the Xiaomi smartphone?

If your phone model, country/region, and SIM card carrier all support the call recording feature, you can use it during a call by tapping the recording icon in the Google Phone App interface.
Taking the Xiaomi HyperOS system as an example, you can find your recorded call files in the following steps:
1. Open the Google Phone App.
2. Tap [Home].
3. Tap on the caller you recorded.
Note:
If you recorded the most recent call, go to the player on the [Home] screen.
If you recorded a previous call, tap [History]. Then select the recording from the list of calls.
4. Tap [Play].
5. To share a recorded call, tap [Share]. You can share recorded calls to supported apps, such as email or messaging apps.
