Do I understand correctly that you want to use a separate program? Why? If you change csc, the native call recording that works best will work.
[Samsung Galaxy S22 Ultra] renek11:
And it doesn't matter that the EUX firmware is AVG6 and SEK is even older AVF5 ?
[Samsung Galaxy S22 Ultra] TODI1111:
I always make sure it's the same. The difference between updates is usually a few days. SEK csc received AVG6 today.
[Samsung Galaxy S22 Ultra] renek11:
Do you think this method will work for a long time, or could it stop working?
[Samsung Galaxy S22 Ultra] TODI1111:
I am an optimist, so I trust that it will last a long time. ;)
[Samsung Galaxy S22 Ultra] masterci:
Yes because I know native call recording start a new call with a message to inform the call is recorded.... and it's not good!
[Samsung Galaxy S22 Ultra] tsilva30:
If your phone came with SEK from factory if you change to EUX you will lose OTA... What's your last ID? EUX or SEK?
[Samsung Galaxy S22 Ultra] sbassios:
With the first step what do you mean?reboot via samfw?

i changed the csc to SEK but recording doesnt start and it is greyd while i am talking.I tried the steps to change the csc 2 times but it didnt help.

now i have sek/sek,sek/eux/cos
[Samsung Galaxy S22 Ultra] Droidphilev:
Try the latest version and forget what i wrote
[Samsung Galaxy S22 Ultra] sbassios:
i cant use the call recording with wifi calling,why?
[Samsung Galaxy S22 Ultra] Tomasz_Anonim:
Question. I have EUX Exynos, when I move to SEK I will get OTA, call recording but I will not have call id. The csc which provide me call recording and call id is INS. I will lose OTA when moving there (according to video). But what happens if I move back to EUX? Will I regain OTA?
[Samsung Galaxy S22 Ultra] gpap2004:
No , it's not true. This is not happening to Samsung.

This is only inside Pixels phones
[Samsung Galaxy S22 Ultra] gpap2004:
No one can. This is an internal phones policy
[Samsung Galaxy S22 Ultra] masterci:
Really true????? Nobody said it's only for Pixels phones!!!!!!! I immediatly change the CSC!!!!
[Samsung Galaxy S22 Ultra] gpap2004:
Oh, yes !! No beep , no messages!! You just have it to auto recording - if you like it- (through phone settings) and you never have to worry about!
[Samsung Galaxy S22 Ultra] masterci:
I change CSC only to have call recording!! I need to press button REC every call or I can set automatic auto record?
[Samsung Galaxy S22 Ultra] gpap2004:
Me too.
[Samsung Galaxy S22 Ultra] saturn3000:
In the phone application settings you can activate automatic recording for all phone calls.
[Samsung Galaxy S22 Ultra] masterci:
thank you very much!!!
[Samsung Galaxy S22 Ultra] renek11:
I have a factory EUX and changed to SEK. It should work normally OTA for me, but Ukrainian, right?
[Samsung Galaxy S22 Ultra] tsilva30:
Most likely you regain OTA, yes. But do it and give your feedback..
[Samsung Galaxy S22 Ultra] TODI1111:
The OTA update works fine for me. Even with the previous version, I switched from EUX to SEK and yesterday I updated my device OTA.
[Samsung Galaxy S22 Ultra] gpap2004:
Yes , you have OTA Ukraine update. Usually, you have it just a few days after EUX update
[Samsung Galaxy S22 Ultra] tsilva30:
Can you change back to EUX to see if you still receive OTA's? When a new OTA arrives of course..
[Samsung Galaxy S22 Ultra] Dan Z good man:
Hi there, I have a Samsung galaxy A71 (SM-715W) Canadian version.

It has XAC (CSC) meaning all the CSC within the firmware is only for Canadian carriers, unlike the international version with XOM (CSC) which is multi CSC that contains over 90 individual CSC from all over the world.

I read some places including here on the XDA forum that if I flash my device with Thailand's CSC or Indian CSC, the native call recording will be enabled.

The problem is that I don't know which software I can flash it with to get the call recording enabled.

for example, if I pick Thailand's firmware, which one exactly do I have to do it and the steps to do it

I can probably manage to read about the process of how to do it as long as someone tells me which firmware I have to download and flash it with.

I do appreciate it if you can tell me or walk me through how to do it

Thanks in advance
[Samsung Galaxy S22 Ultra] abbastanza:
Good evening everyone. For a few weeks now I have been the owner (I still haven't figured out if I'm happy or not) of a Samsung Galaxy S22 Ultra Exynos SM-S908B / DS. I live in Italy and I had enabled the call recorder on my previous Huawei P30 and I was very disappointed to discover that the S22 Ultra had it disabled (in the European version). Thanks this thread, using the SamFw FRP Tool 3.1 software and with the help of this tutorial in Italian I changed the CSC easily and in a few minutes. Free of charge (unlike using SamKEY). Now my CSC looks like this:

Everything seems to be working fine. Except the anti-spam call service. Thank you all.
[Samsung Galaxy S22 Ultra] saturn3000:
For antispam you can use the Hiya app to download from the Play Store. Samsung antispam is based on Hiya.
[Samsung Galaxy S22 Ultra] Rapier:
Installing Hiya will not give you the same experience. The separate Hiya has it's own dialer and is not integrated within Samsung dialer, if you use the phone dialer the notifications and info regarding calls are on top of the actual call screen and so on...

Having the integrated spam protection working is different
[Samsung Galaxy S22 Ultra] Rapier:
So you want to record someone without him/her knowing and without getting consent...well that's not good either
[Samsung Galaxy S22 Ultra] saturn3000:
But Hiya is a good alternative if you want to have call recording. There is no possibility of having both integrated antispam and call recording for model S908B. It is only possible using a CSC not foreseen for the European firmware but OTA updates are lost.
[Samsung Galaxy S22 Ultra] Rapier:
You are right on this one and it depends on what everyone needs. I don't need call recording but I would like the integrated spam protection
[Samsung Galaxy S22 Ultra] saturn3000:
Sure, you are right but here we talk about how to have call recording so whoever is interested in this topic is because they want this feature.
[Samsung Galaxy S22 Ultra] Philip:
That depends on why you are doing it and what jurisdiction you live in. Here in the UK there is no requirement for individuals to obtain consent before recording, provided that there's no malicious intent. (Rules for businesses are different).
[Samsung Galaxy S22 Ultra] Rapier:
In the countries where the function is disabled, the law doesn't allow it...that's why Samsung blocked it. Or at least this is what they say. And if phone cannot be clearly identified as of a personal or business use, they disabled it for all.
[Samsung Galaxy S22 Ultra] saturn3000:
This is not true, Samsung has blocked registration throughout Europe but for example in Italy it is legal to record calls if one of the interlocutors is whoever is recording but it is forbidden to spread the recording to the public.
[Samsung Galaxy S22 Ultra] Rapier:
Probably in every region/country where it is something forbidden but not possible to control (you can't know for sure that someone will or not make public the recording) they just considered easier to block it entirely. Maybe is not right but you can't argue either. Only way is to change CSC as long as this still works

And the ultimate argument is that according to GDPR, consent of the other party IS required. And this is across Europe and above any speciffic laws any country would have. So even if in Itally you are allowed somehow to record calls, GDPR states that you need consent. And since this is across all EU Samsung disabled the function to avoid legal disputes.
[Samsung Galaxy S22 Ultra] Philip:
Sorry, but you are factually inaccurate on two counts.

1) If the recording of calls is blocked because it might be done illegally, then Samsung would also have to block the ability to make phone calls (because certain types of phone calls are illegal) and to access the internet (which again might be done for illegal reasons).

2) There is nothing within GDPR which prevents the recording of telephone calls, even without consent. It might be possible to breach GDPR depending on how a recording was subsequently published, but the actual ability to record the call is absolutely not prohibited by GDPR.
[Samsung Galaxy S22 Ultra] ChoSmile:
Bad news for people with S22 SM-S908B (Exynos) who used INS CSC (the one from E (snapdragon) model to have Call recorfing, anti-spam callerID and Samsung Pay.

Until now we just make updates manually (BL, CP, AP, HOME_CSC) every month with any B FW (for example EUX) and were was up to date.

BUT ....

from version S908BXXU2AVH9 - Samsung removed the glitch ... so no more INS for B model ... CSC returns to EUX (or original CSC) and call recording, internal andti-spam callerID and Samsung Pay were gone.

At the moment the ONLY working CSC with Call Recording is SEK (Ukraine).

So with SEK (plus and minus):

+ Call recoeding works

- no internal anti-spam callerID (Hiya as app can be used from playstore)

- no SPay (the re is no working option at the meoment)

+ OTA firmware updates will work (via Setting menu).
[Samsung Galaxy S22 Ultra] ardy2:
I have similar situation in G780G (XEO but changed to XID) - after last OTA "About software" shows EUX/XEO instead XID and Play Store claim that device is uncertified. But... in this update Samsung changed firmware version XID vs XEO (and SEK). Currently I have G780GXXU3CVH3 but if I reflash (Odin) with XEO (or SEK) version ended ...H1 (with HOME_CSC...) phone working and marked as certified, but there is no carrier (no cellular at all). If I reflash previous version (which has identical version for XEO and XID) phone has bootloop.

Is there any chance to return to XEO (or SEK better - for call recording) without lost my config?
[Samsung Galaxy S22 Ultra] VR133:
I'm from Sri Lanka. I'm using S22 (SM-S9**E). I tried many CSC but they do not work correctly, But after using XXV it's working perfectly fine. Thanks very much, ChoSmile for the guidance.

Did you reset the phone or everything works without resetting?

[Samsung Galaxy S22 Ultra] Brixster:
Ok guys, I've read through every message to fully understand the process before jumping in and activating the call recording, and would appreciate any helpful comments please.

It seems the best option to change the CSC while keeping most of the Samsung functionality is to use the SM-S908E model and change to INS (India). Can someone please confirm that after doing this Samsung Pay and Caller ID Spam Filter will work in the US as it does on a native version (U) of the phone, and that the OTA updates work as usual?

I also read somewhere (minor point) that when they changed their CSC to SEK the phone dialer numbers no longer parsed with hyphens properly for US numbers. And someone else raised the question of whether using an "E" phone in the US would limit or restrict the LTE bands used for the network. So, does anyone know whether this is the case using the INS code?

Finally, I need a good source who sells the SM-S908E and would ship to the US?

Thanks!
[Samsung Galaxy S22 Ultra] karan_adhikari:
Hello Everyone... Is it possible to change the CSE file in s7 edge INS SM-G935F, I am looking to have the native call recorder on it.

Thank you

Try and share result.

It will changed or stay same.

EUX is SM-S908B model.
[Samsung Galaxy S22 Ultra] IronSingh:
Hi guys I read a good portion of this whole thread.

Went with ins CSC I have call recording and s pay but I can't register cards unless I have Indian cards. Is there a work around for that?
[Samsung Galaxy S22 Ultra] Username not available:
Hey guys,

Reading this thread alot and now i'm quite confused.

Can anyone verify if my assumptions are correct?

I don't have a S22 ultra yet, going to buy one within a week.

I really do need call recording as i had on my P30 pro. Also i'd like the spam caller id filter in the stock dailer.

I'm in the EU, but through my job i could buy one from Hong Kong, so i can buy both the "eu" equinox with eux csc and the "hong kong" snapdragon with tgy csc.

As i understand i have 2 options:

1 Buy the hong kong one and flash the csc to INS

2 Buy the regular eu one, flash to SEK

Wich is best?

Some users said on other forums you can not change the csc of the hong kong one, some say you cant change to INS without a indian sim card. Is this true?

If i buy the eu one, flash to SEK, i'd lose the spam caller id and s pay. Is this true?

Wich one schould i buy to get both call recording and spam caller id filter.

I don't care much for samsung pay, i always use google pay.

Thx in advance.
[Samsung Galaxy S22 Ultra] ChoSmile:
Samsung Pay and Bank (card issuer) must have contract. Not all card can be digitized in Samsung Pay. (Same is in Google Pay, and so on).

At the end of procedure SMS confirmation code is sent to number registered in bank. No India card required.

Hong Kong official sells SM-S9080 - there is not CSC wirh call recording.

Same is SM-S908U (US), SM-S908U1 (US), SM-S908W (Canada), SM-S908N (Korea) - all of them do not have CSC with call recording.

Call recoding have:

- SM-S908Е - INS, XXV, THL, MYM, XID ...

- SM-S908B - SEK

INS also hace call ID and Samsung Pay

XXV also have Samsung Pay, no call ID

THL,MYM,XID also have call ID, no Samsung Pay (XID have local Indonesian SPay)

Can NOT flash firmware from one (0,U,U1,W,N,E,B) model to another.

CSC can be chaged between CSCs in same model (with SamFW (free), Samkey(paid), combination firmware...)

Exception is for E model XID, because in SingleCSC, can be chaged with flash.

Old methods for changing CSC with local SIM card, modified theme and *#272*IMEI# are fixed by Samsund and not working.

So, IMHO - model E with INS is the best. (also according to your criteria THL, MYM, XID).
[Samsung Galaxy S22 Ultra] Username not available:
Thank you for your reply.

So i will not be able to use the Hong Kong one to change csc to INS. I didn't know there was a different snapdragon model in Hong Kong. You saved me a lot of headache. Many internet points to you!

I'll try to find a sm-908e on the internet.
[Samsung Galaxy S22 Ultra] Janhaus:
Q - I just got my S22 Ultra yesterday, have been a longtime skvalex user for 10 years, but always with root on other phones. I set up the call recorder in accessibility options, but how do I get call recording to work? Can you provide details (Recording Method, System recorder? )

Sorry: After reading the entire thread I realized we need to change the CSC for this to work. And that this is not even possible for my US model of S22 Ultra
[Samsung Galaxy S22 Ultra] dj24:
So I guess U and U1 models based in the U.S can't take advantage of this then..
[Samsung Galaxy S22 Ultra] Janhaus:
Not from what I'm reading in the thread, no. Sigh...
[Samsung Galaxy S22 Ultra] babyboy3265:
Here I am with an S908N wishing to get rid of the Korean bloatware and also remove the camera sound :D Samkey does not support the N version. Even though it supports the E version and they are both snapdragon..
[Samsung Galaxy S22 Ultra] elmor0:
If already rooted - why not try FireFDS kit LSposed module? - Option of activating native call recorder amongst other goodies.
[Samsung Galaxy S22 Ultra] saturn3000:
I just tried to change CSC in S22 Ultra S908B from EUX to SEK and vice versa and it works perfectly with One UI 5.0 S908BXXU2BVJA.
[Samsung Galaxy S22 Ultra] ZayaanAhyaan:
I got the HK variant and use Cube ACR for call recording.....been using it for months without missing any recordings and works flawlessly in the background. Also, gives more options than native call recorder like what calls to avoid recording automaticallyeven on Teams/Whatsapp Botim etc.

Samsung Pay and all Dual SIM features work perfect as well...

Hello, did the csc change always with SamFW on my S22 but now with Android 13 I can't change anymore - someone else with the same problem?
[Samsung Galaxy S22 Ultra] ChoSmile:
Works on aos 13 too.

Check if Developer options > Via USB is enabled and ADB device is authorized.
[Samsung Galaxy S22 Ultra] saturn3000:
For me it worked perfectly with S22 Ultra Exynos SM908B and Android 13, I tried to change from EUX to SEK and from SEK to EUX.
[Samsung Galaxy S22 Ultra] appetitefordestruction:
After a complete reset it still works. I also changed from EUX to SEK but I noticed that I did not get the Update to Android 13 with SEK CSC. First I had to get back to EUX again und than I had to do a reset with loosing all my data to get the update. Now I have Android 13 changed again from EUX to SEK and hope we still get OTA-Updates without problems!

BTW: Does anyone know if its still possible to use ODIN to flash new firmwares?
[Samsung Galaxy S22 Ultra] csikibandita:
Hello! Does call recording really work on the SM-S908B - SEK? I downloaded the SM-S908B - SEK, installed it with Odin, but EUX remained. What needs to be done to change? thanks
[Samsung Galaxy S22 Ultra] ChoSmile:
Yes, as phone is on sek now - updating wirh odin with eux downloaded files (ap, cp, bl, home_csc) - will not change csc and data will stay. Or wait to release sek ota.
[Samsung Galaxy S22 Ultra] ChoSmile:
You can not change csc by odin flashing*. eux and sek have same files. Use SamFw (free) or Samkey (paid) to change csc to sek.

(*exception is for singlecsc like xid but for s22 series xid is in E models, not B.)
[Samsung Galaxy S22 Ultra] csikibandita:
Yes, I downloaded it from: https://samfw.com/firmware/SM-S908B/SEK/S908BXXU2BVJA Unfortunately, it doesn't change. Will the "ota" version also be found here?
[Samsung Galaxy S22 Ultra] ChoSmile:
Read again!

Use SamFw or Samkey to change csc to SEK
[Samsung Galaxy S22 Ultra] csikibandita:
Okay!
[Samsung Galaxy S22 Ultra] csikibandita:
It worked! It works. Thanks for your help.
[Samsung Galaxy S22 Ultra] SamuraiVJ:
Same problem I am facing, I changed XXS to INS with s908e model only which should have OTA updates but I am not able to get it.. :(
[Samsung Galaxy S22 Ultra] Klotar:
If I read the previous posts a few pages back correctly, if I have a SM-S908U1 OYM XAA (S22 Ultra, US Unlocked version), there is NO CSC that I can use that will enable call recording, is that correct? And that I should give up on trying the SAMkey/SamFW route to change the CSC, right?

Thanks in advance. (I know what the post says so I think I am SOL but thought I would confirm).

EDIT/ADD: I've now read the entire thread and looks like I am definitely SOL - oh, well...

Tried to change the CSC to Ukraine and Israel and it enables the option in my phone settings but nothing seems to happen. When I make a call I see the record option but its greyed out.

Model Name : SM-S908B

Is there anything else I should do? Should this work?

Cheers
[Samsung Galaxy S22 Ultra] DaOldMan:
Israel has the 908E model so please stop trying to use that. It should revert by itself after restart. Restart your phone and check out the csc. You need to use the one correct for your model. Ukraine is probably correct. No idea why you can't record.

For SM-S908B model only SEK csc.

I do not know of any ouf the U CSC has internal spam (probably not).

Just install Hiya app from PlayStore and it will shows (in popup window) if caller is recognised. (Automatic block is payed but info popup is free. Works on any device and any csc.

Hiya: Advanced Caller ID, Spam Blocker, Secure Visual Voicemail

OK so figured out call recording only works on mobile network calls, does not work on WiFi calling. So the recordings are now working, however I only hear myself on the recording, not the other person.

Any ideas?

Cheers
[Samsung Galaxy S22 Ultra] DaOldMan:
They never work on wifi calling. That's internet calling like Whatsapp and Telegram calls, not real cellular call.

It should work perfectly both sides. Do you use any call recorder?
[Samsung Galaxy S22 Ultra] PrivateMarcus:
Which CSC should i choose? I have SM-S908B OXM EUX. 1. Priority is call recording and OTA updates. Call ID would be nice as well, don't care about samsung pay.

Also, is this correct:

1. This does not trip KNOX or void warranty, right?

2. It's fully reversible. I would really appreciate your insight. Thanks.
[Samsung Galaxy S22 Ultra] ChoSmile:
For B model (SM-S90*B) only SEK CSC (Ukraine) have Call recording.

OTA works, when update relesed for the active CSC.

Internal Call ID not supported. Same service is provided as external app Hiya on any CSC.

Samsung Pay also not available in SEK.

1. Yes, KNOX not tripped, warranty preserved.

2. Yes, CSC can be changed unlimited times. (at least until Samsung decided to forbid it (like for Korean models N - SM-XxxxN).
[Samsung Galaxy S22 Ultra] DaOldMan:
All is correct but #2 may not be. Not always CSC can be changed unlimited times. Some unlucky people reported that when they changed CSC to some other country then in the new CSC they were not able to enter TEST mode and couldn't easily change csc again. So beware. I have no idea if they managed in the end and how.
[Samsung Galaxy S22 Ultra] appro77:
Is VoLTE compatibility affected by changing the CSC?
[Samsung Galaxy S22 Ultra] ChoSmile:
According to my observations and experiments with CSC changing on S9...22, Note9...20, A52(s) - not affected, works on any CSC, as long as there are ims/xcap APNs (some carriers requires them, at least ims).
