Robocallers and Spam callers constantly change their phone numbers to avoid being detected easily. To identify them and ensure that you have a superior experience, we update the Spam list in the background. If you suspect that it is not happening, here are a few things you can check:
- Check if you have purchased Truecaller Premium. Frequent Auto update of the Spam list is a Premium feature.
- Check if you have given all Notifications permission to Truecaller.
- Don't force-quit Truecaller. If you force-quit the app (by double-tapping the home button and swiping up on the app), then iOS prevents background updates from happening until you relaunch the app.
- Enable Background App Refresh for Truecaller. You can find this setting in iOS Settings > General > Background App Refresh.
