3.  Issues with Notifications, Incoming 

Caller Alerts, Reminders and Alarms

• All reminder and notification features require you to 

authorize Runmifit in the permissions on the paired 

phone. For troubleshooting issues, please uninstall the 

app, re-download and install, and agree to all 

authorizations for Runmifit. 

• If call notifications are turned on, and the device does 

not vibrate when the phone receives a call, then check 

that Bluetooth is turned on and linked with the device, 

then check that Runmifit app is working.

• If the message reminder function is turned on, and the 

device does not vibrate, please check that the app 

meets the following conditions – alerts are allowed when 

screen is locked, and previews allowed always (default).

4. Variations in Step Count Data
