Keep calls syncing on Xiaomi, Redmi and POCO

Turn on autostart

Autostart lets LumaKol wake up when a call ends, even after you swipe it away or restart the phone.

• HyperOS: Settings → Apps → Background autostart (a tile at the top of the apps screen), then switch LumaKol on
• MIUI 14: Settings → Apps → Manage apps → LumaKol → Autostart (in some versions under App permissions → Background autostart)
• Older MIUI: Security app → Permissions → Autostart, then switch LumaKol on

Set battery saver to No restrictions

Open LumaKol’s app info page and remove the battery limits on it.

• HyperOS 2: Settings → Apps → Manage apps → LumaKol → Battery → Battery saver → No restrictions
• HyperOS 3: Settings → Apps → LumaKol → Power → No restrictions
• MIUI 14: Security app → Battery → App battery saver → LumaKol → No restriction
• On the same app info page, switch off Pause app activity if unused, if your version shows it

Lock LumaKol in recent apps

Open the recent apps screen, long-press the LumaKol card and tap the padlock. On some versions you pull the card down instead. A locked app is not cleared when you tap Clear all, and the phone is less likely to close it.

Set up call recording in the dialer

Which steps apply depends on the dialer your phone uses. Check Settings → Apps → Default apps → Phone app (wording varies) to see which one it is.

• Xiaomi’s own Phone app: turn on automatic call recording in its settings, where your model and region offer it. Xiaomi saves these files in MIUI → sound_recorder → call_rec on internal storage.
• Google’s Phone app (used on many HyperOS phones): Xiaomi says recording works only where the model, country and carrier support it. Google keeps these recordings inside the Phone app, so LumaKol cannot match them. Calls and outcomes still sync.

Turn on recording matching in LumaKol

In the app, open More → Calling and switch on Sync dialer recordings. The app then matches your dialer’s recording to each lead call and saves it where your workspace chose, by default your own Google Drive, which the app asks you to connect. Until it is connected, the file stays on your phone, and saving waits for Wi-Fi unless you switch off Save recordings on Wi-Fi only. If the app asks for access to music and audio, allow it: LumaKol reads only audio files your dialer creates around the time of a lead call. Recordings folder, under the switch, is set to Automatic, which searches the phone’s audio library and finds most dialers’ files on its own.

Point LumaKol at the folder if needed

If calls in the Calls tab say No recording found for this call while the dialer did record them, open More → Calling → Recordings folder. The phone’s folder picker opens: go to MIUI → sound_recorder → call_rec, tap Use this folder, then Allow. LumaKol keeps this access after a restart.

Test with one call

Call a lead from LumaKol, talk for a few seconds and hang up. The outcome prompt should open straight away. Lock the phone, wait a few minutes, make one more call, and check that it also appears in the Calls tab with the right lead.
