Caller ID Question:

I have a question regarding Caller ID.
Over the years with CallerID feature I always thought that caller's name & phone number would display even if it is not in my contact list. It would only show the phone number of the caller. That is how it has been ever since I had cellphone.
Previously I had HTC Magic and even that phone would only display the phone number only for callers that was not in my list.
Now not too long ago I purchased a Bell's Samsung Galaxy S i9000 which was rooted and already had JPK running. I currently have it running on Rogers Wireless Network. Sure enough even with this phone only callers' number would display.
Few days ago I actually flashed back to the stock firmware for this phone, which is JH2 firmware. I was suprised to see that phone would now display the name of the caller! +obviously the number, even if it was not listed on my contacts! (I actually received a call from wrong number). What is more shocking? was that I used my Skype(PC) to do a test call and as usually it would display with funny phone numbers like 01234567, etc... BUT! it literally displayed my Skype(PC)'s user name !!
So my question is, what is required to display the unknown callers name? and not just the number as usual?
I am sure it is not hardware based but up to the phone's operating system?
Could someone explain this to me?
Thank you.
Firmware aside
one thing i do know, is that there are 2 Caller ID services now in day in all Canadian/USA telcos (not sure about internationals)
the standard old caller ID if paid or included in your plan, you will always get the phone number of the person calling you, unless the dialing person brocked it.
the NEW caller ID which is usually an extra fee to enable or included in your plan, will show your the caller ID name (even if it's not in your address book) if it's not broked
so from your experiment, it appears that some firmwares are missing the support for the NEW caller ID feature

Caller Id showing unkown caller instead of phone number

My s6 is stock rooted running 5.1.1 and it used to show the phone number anytime i got a call from someone not in my contacts list but last week it started just showing unknown caller. The caller's phone numbers show up on the call logs, but not on the call screen. I haven't changed any of the settings recently or installed or even updated any apps. I checked all over but I can't find anything on how to change it back.

Caller ID - Location

The other day I received a couple of calls from numbers I'm not familar with. When the calls came in, only the number was shown on the incoming call screen. Later I noticed in my call log that those numbers show a state in the log. Although it's only a state it is better than nothing. Why does it not show this info when the call is incoming? Is there a way to change this? I did not find any caller ID settings.

I am using a 920I on AT&T on firmware for XSP. When I get a call from a number I do not have stored it shows what state the call is coming from. I do not know of a setting to change this.

Wrong call ID.

I have had this issue from the beginning when I got the phone, which was 1.5 years ago or so. Issue is that when I receive a call, the ID is shown the call before that. Example : I have received a call from CALLER A and after if CALLER B calls me, ID is shown as CALLER A for about 5 sec or so. I have updated the phone, reseted and so on. Current version is EVA-L19C432B386 model is EVA-L19. Using 2 sim cards on it, I have tested this with only 1 sim inserted. Does anyone have any info how to fix this or something like that?

Help Please ! Unable to recieve calls from certain numbers after Nov 2021 firmware update.

Hi All. Before I give you the whole story. I have a Note 9 N960U1. After the Nov 2021 update I cant recieve calls from some numbers. I have done a system flash but still same thing. And if those numbers call me from a hidden number I can see the call but with an unknown number. I have tired every thing. System reset. Delete number. Checked call forwarding, checked donot disturb and checked block list. Infact removed all numbers from block list. Still same thing.
So this first happend to my colleague at work. He came next day and won't answer my phone. At my end the call is going through, meaning I can her it ring till it goes to the voice mail but he dosent see any notification on his screen only voice mail notification if I leave him a voice mail. So at first i though he was just bullsh***ng me. Next day he came and showed me. He has the same model as me Note 9 but the exnyox version. So week before Christmas I got the notification for the system update and so I went ahead and updated my phone and my wife's. We both have the same phone and guess what now I can't receive calls from my wife. If she hides her number I can then recieve her call but with a private number or unknown number.
I posted this on redit and another person verified that they can't recieve calls from certain numbers as well after the update. I do recieve calls from some number but there is no correlation between who's number I can or can't see. Also we are all on different network providers. Also all phones are factory unlocked.
Any help would be great. Please. Thank you in advance.

If your phone depends on a carrier you may try to ask them if it's not an issue with their network and secondly if they didn't release a corrupted firmware...
If this is the case, they should propose you a procedure to downgrade your firmware till they fix the problem !

All the phones are factory unlocked. Not paired to a carrier.
