S21 is blocking phone numbers not on blocked list

[Joeyjoio]

I had a message from my mother asking me why when she phoned was I always on another line. It was odd as I hadn't been on my phone. On further investigation it appears that my phone has been blocking her number. It says "blocked call, blocked by phone". I have checked my blocked call list and her number wasn't on it. Out of paranoia I have removed all of the numbers from my blocked call list. Does anyone have any idea how to unblock her number?

@AndrewL @There's a gentleman man named Welsh Paul a few comments up you guys should hire him because I did what he said and it worked for some reason the numbers are being listed as spam and when u search in settings for caller ID spam protection change the setting to just high risk and not high risk and spam protection ur calls will come ladies and gentlemen at least they did for m

I've had this exact thing happen to me with the number I communicate the most with which is my husband's number just out of the blue for some reason and his number was not in the blocked calls list. I had an option checked that blocks all scam calls, but instead, I checked the option that blocks only high risk scam calls, and that seemed to work for me. Try that.

Thank you! This totally fixed it. I didn't need to delete anything, just temporarily remove or change the phone number from the contacts app. Then in call history it will show up as 'Spam Call'. Tap it, then the 'i' button, and then 'Report' as not spam. Then change the contacts phone number back and all is fixed.

This seems like a bug that people in your contacts can be marked as spam through the Hiya service.

Hubbys phone was blocking me!!  Lol. Tried everything. Then found this that solved issue and fixed me being blocked. 
Tap Phone, Tap Contacts on bottom right, Tap 3 dots on top right, Tap Settings, Turn off Caller ID and Spam Protection. 
Hopefully this helps someone else.

@slemerond4313 @The best option is for him to take you off his spam list that's what actually turned out to be the issue them he can reapply the setting and it should still let u through ur on his spam lis

This happened to me a while back and it turned out that an update had changed settings. I changed them back and it was fine.
