Missing recordings are almost never a bug in the app — they're a device setting. Here's the checklist that fixes 95% of cases.
Point the app at the right folder
Every OEM saves call recordings to a different path (Call, Recordings, MIUI/sound_recorder…). In the agent app, set the recording folder to match what the phone's dialer actually uses.
Turn off battery optimisation
- Allow the app to run in the background
- Set battery usage to Unrestricted
- Lock the app in the recents screen on MIUI
Enable native call recording
The app can only sync what the phone records. Make sure automatic call recording is switched on in the dialer settings for all numbers.
Once these three are set, recordings sync automatically within a few minutes of each call.
