Can't know the caller or answer while the mobile is locked

[Android Central Question]

I have note 9 and got the update of pie and it was ok..
Until few days ago.. when i found that i cant know the caller name when the mobile is locked unless i put my pin in .or press back to call option.. and that didnt happen before as i just swipe the answer button on the locked screen..even if i have pin security

Boot in safe mode and see if it works properly.

I just tired because I usually look at my S3 Classic watch.

I left my phone locked and a spam came through and didn't have anything but a number (I'm guessing it was spam, no message).
I called from my work desk phone, which is in my caller list and it came up with the caller ID, phone number and state.
I also tried another line on my phone, not in my caller list, and it just showed the number.

What carrier, locked or unlocked, country, etc., do you have?
