As I mentioned above - It's been reported that in the US issues with Hiya were fixed for those who had the problem were fixed with a subsequent OTA - You can try Clearing Cache & Data for the Phone app - Reboot - But most reports are that you need to wait for the next OTA... Note that for some reason this issue is not affecting everyone... it's not an issue for me.. 🤞🐧
Finally. This will explain the issue that I had with my s8 and the hiya /callerid spam protection. 8 tried doing factory reset, clearing cache. etc. nothing seemed to work. it seems that the upcoming OTA fix will take care of this issue. Glad to know that this was a widespread issue and not a fiction of my imagination as I was told at Customer Care!!
