Galaxy a8 plus 2018, hiya is built in the smartphone for spam protection and caller ID. However it does not detect all unknown numbers but a few numbers were identified in last few months. How can I make it work? It does help to get a caller ID while getting calls.

Look at screenshot and find the "SMART" letters in identified caller ID followed by their name.
