Hey I haven't received the update yet. Possible for you to share a screenshot of the change log? Does the change log say the Caller ID issue has been resolved?
Thanks in advance
Sorry, no screenshot, but you can download yourself. Go to Google Play and download or update "Samsung Experience Service". It has updated again. The most recent update is 10.1 Apri 29, 2019
This is the Android Overlay that Samsung uses. My Smart Call started acting normally again after this service was updated, a few updates ago, earlier last month. Works both on my S9+ and Note 9. They were previously both broken by Pie.
