There are lines that define volte in the csc files. They are probably the same for Europe. But if there is a change in volte implementation in different countries the lines may be different and this may change the behavior.

Guys, anyone found a way to activate call recording on S22 Ultra with snapdragon (S908U1)?
[Samsung Galaxy S22 Ultra] mastabog:
First, many thanks for all your contributions so far - very valuable, and very generous (where do you even get so much info about various countries?)

Second, does changing CSC affect anything else, like 45 or 5G bands? Can one know in advance by looking at the contents of the files, or does one to try and test to see what is lost on each particular phone model?

I changed CSC on my S21+ 5G G996B/DS from XEU to SEK (using samfw frp tool) and now I have call recording, but I do wonder if anything else is lost (besides caller id and samsung pay)
[Samsung Galaxy S22 Ultra] ChoSmile:
I've used a lot of phones and one of the things I need the most is call recording. Before Android 9 (when there was no GDPR), there were several recording programs. After GDPR - things started to become more limited. Since the restrictions that prohibite direct access to the audio stream, some applications start using the microphone(s) (analog recording from high volume top-ear speaker or loud handsfree speaker), which also recorded the surrounding noise, where the "opposite side" in the recording being significantly quieter, therefore increasing the volume (digitally) also amplify the noises (i.e. in noisier environment - the recording was not worth it).

Since then, I mainly use Samsung devices (Note 8, 9, 10+, 20U, S21U, S22U) and I have changed the CSC region by foreign SIM card, by mofified theme, by combination firmware, by *#272*IMEI# code, and other methods that was fixed, now works only combination firmware (hard to find), by Samkey (paid) and SamFw (free).

On all of them recording is allowed in "Phone" application that records it directly from audio stream (both sides). On my phones (and many friends and colleagues with Samsung phones (a lot of S,Note,Flip,Fold,A,... series) with changed CSC regions) I (and They) have NOT notice something (some service, for example 4G, 5G, missing frequences bands, VoLTE, VoWiFi, ... ) or features that not work now but was available/working with the same version of original (different) CSC region.

If you mean some specific - ask. (For example XID also have SPay, but there are local Samsung Pay services and it is useless with non Indonesian card.)

SPay is specific and allowed only in countries where officialy available Samsung Pay (SEK Ukraine do not have Samsung Pay support), also about internal Caller ID (but if needed - can be used with Hiya app).
[Samsung Galaxy S22 Ultra] Philip:
There is nothing in GDPR which prohibits the recording of telephone calls.

Whatever the reason why Samsung and others do not allow call recording (not wanting to fall foul of the legislation regarding consent in the different jurisdictions in which their handsets are sold is my guess), it has nothing whatsoever to do with GDPR.
[Samsung Galaxy S22 Ultra] mastabog:
I think @ChoSmile referred to timing (GDPR coming into force) rather than GDPR regulations. In general *private* information that is clearly meant for you (such as emails clearly addressed only to you, or other forms of communication clearly addressed only to you) becomes your property and there is no law preventing you from doing whatever you wish with it, including publishing it (public information, or information that include personally identifiable tokens of other people apart from the the sender and yourself, is another matter). For example, those disclaimers at the end of emails that some people insist on adding, saying you are not allowed to reproduce the content of the email because of some "legal" reason have zero legal powers. Sometimes I annoy them by saying I'm not going to reply to their emails unless they remove the disclaimer as it has zero legal implications and hence it's just abuse as far as I'm concerned.

I presume Samsung simply wants to stay out of the EU commissions crosshairs, because GDPR requires you to obtain consent in case you wish to use the recording in a court of law. Anyone can record conversations whether or not Samsung allows it.
[Samsung Galaxy S22 Ultra] Philip:
Can you please show me where in the GDPR it says this? (Hint: it doesn't)

The requirements for consent to record vary in different jurisdictions, as do the regulations as to what you can do with the recordings (including whether they are admissible in court of law). The legislation can also vary depending on whether the recording is being performed by an individual or an organisation. None of this has anything whatsoever to do with GDPR.

Also, GDPR is applicable in areas outside the EU - the UK, for example.
[Samsung Galaxy S22 Ultra] mastabog:
Is the the set of 4g and 5g frequency bands dictated by the CSC or the Modem (CP file)? I thought the CSC played a role too, but it's been a very long time since I was playing with android hacks.
[Samsung Galaxy S22 Ultra] mastabog:
Maybe I should have specified - if you process EU residents' data to be used outside of the private context in which they were offered, such as for training purposes, courts of law, etc, then you are required to obtain consent (the actual requirement is a little more complicated, but boils down to you needing to put up verifiable policies that unsure consent is given): https://iapp.org/news/a/how-do-the-rules-on-audio-recording-change-under-the-gdpr/

The EU GDPR is actually not applicable or enforceable in the UK. The UK simply opted to adopt some (most) of the same stipulations under UK law, specifically the Data Protection Act of 2018, and hence one can use that to file complaints against violations of the Data Protection Act. Some refer to that part of the DPA as the "UK GDPR".
[Samsung Galaxy S22 Ultra] ChoSmile:
Depends of what is the phone's current Active CSC?

There are five Mexico's CSCs: TCE, TMM, UNE, ISU or MXO

Settings > About phone > Software information > Service provider software version

second line, first three lettes:

Step (1)

If TCE/...

If TMM/...

are part of OWO MultiCSC.

If UNE/...

if ISU/...

are part of OWE MultiCSC.

Non of other CSC in OWO and OWE MultiCSCs has call recording.

First need to flash with OXM MultiCSC.

Downalod (via Frija, samfw or sammobile) any of the latest version of INU, XXV or THL version.

Flash via ODIN with four files - BL_, AP_ CP_ and HOME_CSC_ files will not reset phone. (if on [CSC] section instead of HOME_CSC - CSC_ file used - it will reset phone)

If MXO/...

is part of OXM MultiCSC, so you can skip downloading and flashing (all in Step (1) ).

Step (2)

Use SamFw (free) or Samkey (paid) app to Change CSC to INU, XXV or THL.

INU has callrec, callid, spay

XXV has callrec, spay, no callid

THL has callrec, callit, no spay

if INU used first (before flash and csc change) add 3 Indian numbers to block list (otherwise 1 international sms will be sent on evety new sim/esim insirted/added:

+919560345888

+918424098931

+919176905802

Good luck :)
[Samsung Galaxy S22 Ultra] netnerd:
wow. this is insane with 29 pages.

you do know that your phone is ABLE to download apps, right?

download CallApp v2.010 apk from website, it lets you records your incoming and outgoing calls !
[Samsung Galaxy S22 Ultra] WesTokyo:
Native is the key word, CallApp is fine, however Google Play doesn't allow call recording apps in their store.
[Samsung Galaxy S22 Ultra] netnerd:
i didn't know this is a iphone, you not allowed to sideload apps outside of play / apps store.
[Samsung Galaxy S22 Ultra] DaOldMan:
No one said you are not allowed to sideload apps.

All recording apps work badly now, unless you have root access. Maybe you have older Android version. Since Android 11 native call recording is the best option to have. No app, sideloaded or not, comes close. So changing csc is the way to get perfect call recording.
[Samsung Galaxy S22 Ultra] morgej:
When using the SEK CSC on an S22U model SM-S908B, is anyone having problems with their hotspot functionality?

I use samkey to set my SM-S908B to SEK CSC and using on T-Mobile US.

When I am using the hotspot on the S22U, my PC can connect to websites in a browser (Chrome/Eddge) but can not ping any internet host by name (i.e., google.com) or IP (i.e., 8.8.8.8). When using the hotspot, my PC can also not connect to my IPSEC VPN to my home.

When I use the hotspot on another phone (with the same SIM from the S22U), I can ping anything on the internet by name or IP, and can connect just fine to IPSEC VPN.

I also tried a couple of third party hotspot apps on the S22U to go around the native hotspot...and those too have the same can't ping anything on the internet and can't connect to VPN issue.

It is almost like there is a firewall running on the S22U that is blocking ping and whatever port IPSEC runs on.

Is there something about the SM-S908B or the SEK CSC that prevents the phone from passing icmp (ping) and or IPSEC? Any ideas how to fix this without root?

Thanks
[Samsung Galaxy S22 Ultra] ChoSmile:
B models are Exynos and do NOT have mmWave - so can not use T-Mobile mmWave bands (n258, n260, n261) of 5G.

SEK do not restrict VPN - I use OpenVPN (on my SM-S908B) without problem in Europe, Asia and Middle East.

The phone setting that could restrict data are:

Settings > Connections > Data usage > Data Saver

Settings > Security and privcacy > App security> Device protection

Other Third-party Antivirus / Firewall

If you think that "CSC is the problem" - change it to EUX or other CSC - free via SamFw.

Can you ping from phone?

Conenct VPN on phone and then use hotspot to PC.

Instead of WiFi hotspot - try via USB cable to use internet (DialUp on PC, number *99#).
[Samsung Galaxy S22 Ultra] efkosk:
So I report the first and serious problem. I lose my network regularly. Only restarting the phone will help. I don't know if it's caused by a changed CSC or the phone itself.

This can help you with HealthMonitor.

one of my credit cards is accepted in Samsung Pay, but not in Google Pay... but I guess I can live with it.
[Samsung Galaxy S22 Ultra] CoolZoneAlex:
Can SEK firmware be flashed directly to the device without SAMkey? When XID was on Exynos I could flash directly since my terminal is not branded.
[Samsung Galaxy S22 Ultra] efkosk:
I don't see a problem with that. But what reason do you have to not use Samkey?
[Samsung Galaxy S22 Ultra] CoolZoneAlex:
Because I do not need any credits to spend in order to use Odin, and firmware files are readily available on multiple sites.
[Samsung Galaxy S22 Ultra] gpap2004:
Unfortunately you can't. If you flash SEK via Odin , the process will be OK but the CSC wouldn't change as it is the same multi rom
[Samsung Galaxy S22 Ultra] CoolZoneAlex:
I see, but how come with my S20/S21 I did only flash to XID via Odin and Call Recording option appeared in Call menu...?
[Samsung Galaxy S22 Ultra] gpap2004:
The problem with SEK is that Samsung Health Monitor is not working now as it is unavailable for that phone , as it says. Spam protection is ok for me through Hiya app , otherwise the SEK rom is excellent (I don't use Samsung Pay). I tried a VPN to trick the region for Samsung Health Monitor be working, but in vain .
[Samsung Galaxy S22 Ultra] gpap2004:
Yes , in S21 I did the same trick , but in that phone the XID firmware wasn't in the XOM multi rom. And now , in s22 , the XID firmware is in snapdragon versions of s21..
[Samsung Galaxy S22 Ultra] behemot24:
When you did it the phone was in Android 11, right? In Android 12 won't work afaik.
[Samsung Galaxy S22 Ultra] behemot24:
Just an idea - did you try to input it into the 2nd SIM slot?
[Samsung Galaxy S22 Ultra] efkosk:
I have dualsim and both sim cards don't work for me.
[Samsung Galaxy S22 Ultra] gpap2004:
No problem for me. I have an eSIM which is working well even in 5G and a second SIM to slot 1 which is working simultaneously and is working well, too. Maybe , you should try a format and clean install
[Samsung Galaxy S22 Ultra] gpap2004:
Regarding the regions where Samsung Health Monitor is working , I found a list of those countries .

BKD, EGY, ILO, INS, LYS, NPL, SEK, SLK, TUN have Call recording.

I also found that the only CSC which has both native Call recording and working Samsung health monitor ,is United Arab Emirates (LYS). So, if we try to change to LYS, maybe we will be lucky! Except United Arab Emirates will receive snapdragon editions..
[Samsung Galaxy S22 Ultra] CoolZoneAlex:
Why flashing on Android 12 won't work?
[Samsung Galaxy S22 Ultra] behemot24:
because something changed from android 11 to android 12 and it won't work anymore.
[Samsung Galaxy S22 Ultra] behemot24:
what are you going to do? change back to EUX to see if it fixes the problem?
[Samsung Galaxy S22 Ultra] efkosk:
CSC change and factory reset did not solve the problem. I'll probably return it to the store.

I'll probably buy an S22. I don't like the dimensions of the S22 ultra. I don't use S-pen and the width of phone doesn't suit me.

Hi to all, I have sek csc on 908b european s22 ultra, is it possible to have ins csc after android 13?
[Samsung Galaxy S22 Ultra] morgej:
@ChoSmile THANKS for the quick response!

I checked all of those settings and they are disabled so I don't think any of them are causing my weird behavior.

When you have a PC tethered to your SM-S908B, from the PC can you ping to 8.8.8.8 or google.com successfully?
[Samsung Galaxy S22 Ultra] ChoSmile:
No, INS is part of "E" model. (It was possible until several months but Samsung fix it. I was on SM-S908B INS and manually update it but it become EUX.)

Now only SEK have call recording available on B model.
[Samsung Galaxy S22 Ultra] ChoSmile:
Yes. I'm on SM-S908B with SEK CSC but in Europe with European carrier.
[Samsung Galaxy S22 Ultra] morgej:
@ChoSmile thanks again for the quick response!

So very strange what I'm experiencing b/c the same SIM card with the same APN settings in another Samsung phone I have works just fine with the PC connected via hotspot able to ping both 8.8.8.8 and google.com ---- but when I put the SIM card in the SM-S908B and use the same APN, connecting via hotspot I can't ping 8.8.8.8 nor google.com but I can connect to the Internet.

By any chance, do you have a proxy value set on your PC or phone?

Could you post the results of an ipconfig /all from your PC?

Thanks again
[Samsung Galaxy S22 Ultra] ChoSmile:
No proxy on Phone or PC.

Add manually another APN, write just "apn name" and "apn type "default" and select it for using.

Also test with other SIM - non T-Mobile.

G973USQS4ETK2

Sp, no way to install firwaware with lower bootliader version.

Keep in mind that if you find a way to root your current version, you can enable Native Call Recording (any android version and CSC region)

BUT it means KNOX trip, no warranty, no Google Pay, no bank/fintech apps, no security apps, some games do not work... No way back for knox even unroot.

Good luck 🍀
[Samsung Galaxy S22 Ultra] ahmadhelmy85:
thats good but can i install custom firmware on it without rooting

and another thing if i unlocked the Bootloader can i relock it again and flash stock firmware
[Samsung Galaxy S22 Ultra] DaOldMan:
1. You can't install a custom rom without rooting. That's kinda the point, isn't it ? You can't change anything in the OS without root... changing OS to custom OS is a BIG change :-) .

2. You don't even need a custom rom for call recording, all you need is to use the stock rom but ROOTED. Then you can enable the root option in Call Recorder and it should work. You can also enable native call recording when rooted probably. Possibilities are endless. Check the XDA for that.

3. Rooting on Samsung causes the Knox Warranty Bit to change from 0x0 to 0x1 FOREVER ! Even if you relock the bootloader (totally useless on Samsung) Samsung reps will always know you rooted the phone in the past. Also some apps may never work again as they check the Knox Warranty Bit. This includes Samsung Pay, Samsung Health and maybe others - mostly Samsung apps. If you have root you may overcome this but if you unroot and relock bootloader (useless, don't do it) those apps will not work and since you have no root anymore you will be able to do zero to change this.

4. You can always flash stock firmware. Rooted or not. Locked bootloader or not.

Cheers !
