A favorite contact, who has been in my phone for a long time, was suddenly blocked by the phone as spam. I was able to resolve the issue by turning off spam blocker but why would the phone block a number in my contacts as spam? We shouldn't have to deal with unwanted phone calls to prevent wanted phone calls from being blocked. I've seen similar complaints in threads in both North America and Europe dating back to 2017. Please add logic to the software that prevents saved contacts from being blocked automatically by the phone. Thank you!
