@Robbi24: Sorry to hear that you're experiencing this issue. Can you try heading to Settings > Apps > Tap the 3 dots in the top right > Show System Apps > Scroll down to Smart Call, and select it > Storage > Clear Cache, then restart the phone to see if this helps? For the NFC issue, do you have the NFC and Payment option active on your phone (Settings > Connections > NFC and Payment)? If so, try disabling this feature to see if the error messages persist, or tap the 3 dots in the top right > Default NFC Method > Auto Select. Let me know how you get on.
