Hey guys I buy Samsung Galaxy S22 Plus version EU - Exynos chipset. [SM-S906B] - Czech republic.

And am curios how enebled call recording with full work - OTA update(andorid and security patch), Working SPay/GPay, Working CallID

Which CSU I need set ? And its okay to the warranty when phone fail to service?

Thanks
[Samsung Galaxy S22 Ultra] ChoSmile:
INS is Active. Will receive OTA when INS release new firm.

What is the current firm?

...WA2, ...VJB or earlier?

If it is. ..VJB ir earlier - download INS ...VJB and flash. Then update from tne OTA menu will work.
[Samsung Galaxy S22 Ultra] ChoSmile:
The only CSC with call recording for Exyn9s S22 (SM-S90xB) series is SEK. And it have no internal CallerID and no SPay. You can use CallerID as external app: Hiya (from PlayStore). No Workaround for SPay (at least until on bank of SEK (Ukraine) add Samsung Pay support)

OTA, GPay, VoLTE, VoWiFi, 4G, 5G works fine.
[Samsung Galaxy S22 Ultra] sbam6980:
My current firm is ..VJB.

INS released...WA2 latest firmware but i didn't get it. Why? And What should I do for getting OTA update?
[Samsung Galaxy S22 Ultra] Beji-kun:
What means CallerID dont work ? Its means internal app for cals or what specific? I see on the reddit but I dont understand so much. Thanks fow letting me know :)
[Samsung Galaxy S22 Ultra] ChoSmile:
As I said flash INS VJB...

WA2 will appear OTA.
[Samsung Galaxy S22 Ultra] ChoSmile:
If phone number is in Contacts - it is shown fine.

It is feature for unknown numbers.

CallerID is an option when some unknown number (not in Contactd) call - phone search via Internet and shows "who is" before even answer, so you know if number is reported as spam, advising, scam or ir is some company phone. Even I register my phone - so, wjen call someone who who do not have my number but have CallerID function - will see my name.

Sime CSCs have it internally, but if not - can be used via app called :Hiya

(look at their website for detailed explanation)
[Samsung Galaxy S22 Ultra] sbam6980:
If I don't flash INS firmware, OTA update not working on my device?

And If I flash INS firmware with Odin, OTA work?

Please 🙏 help me.
[Samsung Galaxy S22 Ultra] ChoSmile:
I wrote it several times.

Just do it... or not.
[Samsung Galaxy S22 Ultra] hshah:
Just want to confirm, if I change the CSC on my S22 Ultra (SM-S908B/DS) using SamKey, it won't trip Knox or wipe the device, right?
[Samsung Galaxy S22 Ultra] ChoSmile:
No. No.
[Samsung Galaxy S22 Ultra] sbam6980:
Thanks a lot from my heart 💖. OTA working on my device.
[Samsung Galaxy S22 Ultra] ANUBIS1975:
Hello everyone.

On Tuesday I get my Galaxy S22 ultra 512gb purchased on the Samsung website and I would like to put the native call recorder but I read that it disables the S-PAY.

My question is is there any CSC that activates the recorder and S-PAY works? for me they are two indispensable functions.

I read you
[Samsung Galaxy S22 Ultra] nguyenlucky:
Downgrade to Android 10 with ODIN (no tripping Knox), then change CSC to KOO using Samfw Tool.

Unless you're on a new firmware with build N986NKSU2.... then you're out of luck.

The reason for downgrading because Samsung blocked the CSC change exploit in newer versions for Korean devices (but not elsewhere).
[Samsung Galaxy S22 Ultra] islamcetin06:
I am on N986NKSU1GVJG. People say its not possible on N(korea) devices. Are you sure?
[Samsung Galaxy S22 Ultra] nguyenlucky:
I am very sure, I used G981N (S20 Korea) before, changed to KOO with Samkey successfully 2 years ago. That guy seems knowledgable about global devices but he is spreading some misinformation about regional devices. Such as N models always have call recording (regardless of devices or CSC) or 0 (HK-China) can have call recording with China firmware (no Google though).

Later N models cannot change CSC, yes that's true, but not S20/NOTE 20 series which can downgrade to whatever firmware you want unless you update to the newest version with Bit 2 bootloader, which prevents downgrading to Bit 1 firmware. You still have Bit 1 though, so downgrading is possible.

Korean models can change CSC until somewhere around Android 11 where Samsung blocked it.

After downgrading to A10, you can change to KOO using Samfw Tool or the Google dialer method. Both are free. Then ODIN again to the latest version, CSC will always be kept unless you change again.
[Samsung Galaxy S22 Ultra] nguyenlucky:
Do NOT update to N986NKSU2GVL3 if you still want to change CSC. You are already on the last version that still allows downgrading.

After changing to KOO you can update all you want, I guess you don't need to change again to carrier CSCs :P
[Samsung Galaxy S22 Ultra] islamcetin06:
I can't update anyway, when I try it says registration failed but firmware is official and knox 0x0:) I'll try this method, thank you very much my friend
[Samsung Galaxy S22 Ultra] hshah:
I ended up doing it with SamfW. Glad to have call recording back 🙂
[Samsung Galaxy S22 Ultra] ChoSmile:
Which S22 Ultra?

SM-S908B - No, only SEK have call recording and no SPay.

SM-S908E - Yes, INS or XXV.

SM-S908x other models U, U1, N, W, 0 - No CSC have call recording.
[Samsung Galaxy S22 Ultra] hshah:
I just noticed that whilst I have the option to press the record button during a call, recording isn't started automatically like I've set it to do. Any ideas?
[Samsung Galaxy S22 Ultra] nguyenlucky:
Bro, N models (Korean) always have call recording for several years. Same with latest models. I personally used a G981N (S20 Korea S865) with call recording.

For 0 models, flashing China rom (CHC) will enable call recording (no google though).
[Samsung Galaxy S22 Ultra] ChoSmile:
Three dots menu (top left) > Settings > Record calls > Auto record calls
[Samsung Galaxy S22 Ultra] hshah:
Yeah, that is already selected but I'm still having to manually start recodings.
[Samsung Galaxy S22 Ultra] ChoSmile:
On which CSC is your phone now?

Try another: INS, THL, XXV, ILO, SEK
[Samsung Galaxy S22 Ultra] hshah:
I'm on SEK atm. Will give one of the others a try later on and report back.
[Samsung Galaxy S22 Ultra] ChoSmile:
(reading your other posts)

Oh, you are on S22, right?

Only SEK have Call recording on SM-S90*B series.

My old S22 Ultra (SM-S908B) records automatic on SEK.

* * *

If you on S23 (SM-S91*B) series - then can use INS, THL, XXV, ILO, SEK
[Samsung Galaxy S22 Ultra] hshah:
I have a S908B
[Samsung Galaxy S22 Ultra] ChoSmile:
Turn off.

Restart.

Turn on function again.
[Samsung Galaxy S22 Ultra] hshah:
Something so simple and obvious... worked like a charm. Thanks 👍
[Samsung Galaxy S22 Ultra] islamcetin06:
Today i am changed csc and updated android 13 again with odin. Still cant update via ota it says registration failed. Any advices?
[Samsung Galaxy S22 Ultra] nguyenlucky:
hmm strange, did you see knox status while in odin mode? Registration failed often happens with unlocked bootloader, which trips knox.

Is your csc changed to KOO? (no carrier bootlogo and apps)

Your device might have been tampered with (flashing official rom with ODIN is not tampering)
[Samsung Galaxy S22 Ultra] hshah:
I just had an incoming call (wasn't on WiFi) and it didn't start recording automatically 🙁
[Samsung Galaxy S22 Ultra] ChoSmile:
As I said my old SM-S908B SEK call recs works automatically both in/out-comings from the beginning (an year).

Only VoWiFi calls are not recorded.
[Samsung Galaxy S22 Ultra] hshah:
Pretty sure I had WiFi turned off at the time, but will test again properly in the morning. Thanks again for your speedy responses.
[Samsung Galaxy S22 Ultra] ANUBIS1975:
My S22 is SM-S908B.I have changed with odin the CSC of SEK but I did not activate the recording.I have tried to change the CSC with SamFw but it does not end up connecting with adb even being configured correctly....

any solution?
[Samsung Galaxy S22 Ultra] ANUBIS1975:
Success!!!

I did it by changing the SEK CSC via odin and then I finished changing it with the SamFwFRPTool program in version 3.3.1.

With version 4.0 it doesn't work.
[Samsung Galaxy S22 Ultra] islamcetin06:
Yes changed. Knox 0x0 checked. Device is offical stock and i am using samsung pass weareble health etc. But cant update with ota
[Samsung Galaxy S22 Ultra] nguyenlucky:
Do you have a SIM card?
[Samsung Galaxy S22 Ultra] islamcetin06:
Yes but turkish sim card.
[Samsung Galaxy S22 Ultra] appetitefordestruction:
Hello everyone,

I just want to make sure that call recording can really be activated on the Galaxy S23 models.

Can someone who uses an S23 confirm this? Thank you very much!
[Samsung Galaxy S22 Ultra] saturn3000:
Hi, yes S23 series can also record calls by changing CSC.

Read this thread: https://xdaforums.com/t/s23-call-recording-possibility-of-changing-csc.4548227/
[Samsung Galaxy S22 Ultra] ibizapower2003:
Silly question.

Can you change the csc with Odin rather than samkey?
[Samsung Galaxy S22 Ultra] hshah:
Not sure, but use SamFW instead. It is free and I've used it multiple times on my S908B.
[Samsung Galaxy S22 Ultra] nguyenlucky:
Buy a US unlocked (U1) model and use ACR from Huawei Appgallery for call recording. Don't bother about any versions from other regions, they don't have enough Verizon 4G/5G bands.

You can also use this guide to enable all bands for worldwide use.
[Samsung Galaxy S22 Ultra] dj24:
How do you access the Huawei app gallery on the U.S S22 Ultra?
[Samsung Galaxy S22 Ultra] DaOldMan:
You can't. The firmware is united for many csc, including yours.
[Samsung Galaxy S22 Ultra] nguyenlucky:
you can install APK of it.

The ACR unchained app is available on both Appgallery and Galaxy store afaik, u can use either.
[Samsung Galaxy S22 Ultra] IT_Architect:
WOW! This sounds like the solid gold that I need. Thank you for your response. Does ACR work to record both sides of the conversation in both the S22 and S23 without rooting them?
[Samsung Galaxy S22 Ultra] dj24:
Thanks. Are you using the ACR unchained app on a U.S U/ U1 S23 Ultra device without any issues?

I ask because one of the things holding me back from upgrading to the S23 Ultra is because I wasn't sure if I would lose this recording functionality since google implemented the accessibility restrictions for this feature a while back. I currently use the legacy version of this app (Ver 35.0) that I downloaded from the galaxy store without any issues on my current T-mobile U S22 ultra.
[Samsung Galaxy S22 Ultra] nguyenlucky:
my s22u has native call recording so I dont have ACR. But I used it before and it worked OK.
[Samsung Galaxy S22 Ultra] IT_Architect:
This is exactly where I'm at. Is your S22 a U/U1, is it rooted or not, and which ACR as there are several by the same name?

Thanks!
[Samsung Galaxy S22 Ultra] dj24:
Unfortunately U/ U1 devices sold in the U.S cannot be rooted at this time.

Call Recorder - ACR - Apps on Galaxy Store

ACR (Another Call Recorder) is a free call recorder application. It is one of the best and most advanced call recorders in the Play Store and offers many advanced features such as: - Record calls ...

galaxystore.samsung.com
[Samsung Galaxy S22 Ultra] IT_Architect:
I'm glad I asked because the founder of the ACR brand is Appliqato, historically the best, and why several others have "brand leveraged" their name.

What matters is whether or not this, or any other app, records both sides of the conversation on an S22 or S23 U1. There is no point in going through the time, aggravation, and expense of a new phone if the result would be inferior to a 2018 Note 9 which does record both sides of the conversation. Thus, that it the question.

Thanks!
[Samsung Galaxy S22 Ultra] Ugreen:
I switched from EUX to SEK for call recording and it's fine . But in the phone app I lost the visual voicemail tab. I'm In France.

I still can acces to my voicemail messages but through the calls history.

I haven't read something about this problem...

Thanks a lot.

[Samsung Galaxy S22 Ultra] JazonX:
So in summary for a Non-Rooted Phone, without changing the CSC - What's the easiest way to enable Call Recording?

Which app is reliable and doesnt get killed by the battery controls etc ??
[Samsung Galaxy S22 Ultra] ChoSmile:
Apps: ACR (several identical names, not on PlayStore), Skvalex, ...

* * *

From Android 9 - Google was forced to restrict and ban access to the audio streams in call. Also restrict permission access to "caller's number" during incoming/outgoing call.

So varios apps try to record call via microphone, "local side" is recorderd very well, but "other side of line" is with a lower volume, noisy, need to increece the volume of the speaker(s)" in order to be sufficiently high to be captured by microphone (so people around will listen/hear whole conversation). Microphone level of caputured audio was digitaly increased (high-gain) and the environment аround noises also recorderd - some times higher than "other side voice", so need to put "speakerphone on" to capture "other side voice".

* * *

On some devices permission to use microphone as a source simultaniously during a telephone call also was forbidden. (So no record or "silence".)

* * *

The best way (except csc change for direct audio stream capture of both sides OR root where access is granted or internal call recording can be allowed for any CSC) are external bluetooth devices (bluetooth hanfdfree) with call recording function on it (with own memory) or wired (usb-c) handsfree again with own recorder.
[Samsung Galaxy S22 Ultra] JazonX:
Thank you for the splendid explanation and the clear answer.

Much appreciated for your time and effort.

Hello i have a S22 Ultra Exynos Europe Version.

My Software is EUX/-/EUX/DTM so DTM for German Telekom. Is it Possible to make the DTM to EUX to have a Branding Free Model?
[Samsung Galaxy S22 Ultra] ChoSmile:
No. The last one is "manufactured for" - can NOT be changed.

The FIRST ONE is ACTIVE CSC - features, restuction, branding apps are from the CSC that can be CHANGED ONLY. Your currect is EUX. If you have other apps (branding specific) you can only uninstall or dissable them.
[Samsung Galaxy S22 Ultra] neophyte1983:
Okay so i must live with DTM and later OTA
[Samsung Galaxy S22 Ultra] ChoSmile:
OTA comes when new firmware is released for ACTIVE CSC - so your phone is on EUX.
[Samsung Galaxy S22 Ultra] DaOldMan:
It's in fact nor possible to change the last csc DTM but that doesn't matter one bit. It was possible to change the EUX country ISO. That is the reason you have EUX but the device is still locked to the branded country ISO you want to remove. It's not the last csc code (which just shows the original csc and is used for nothing else). They used to use the Aliance Shield app, but I understand it has now knox licence issues. Maybe check their telegram page for work around:

Samsung Pay in german, CSC is EUX fix, 5 minutes

Hello This also works with most Samsung phones If anyone is struggling with Samsung pay being in German and has the csc being EUX, I know how to solve the issue and it only takes about 5 minutes. Basically the csc is set to EUX, which is the new European standard, but for some reason, Samsung...

Cheers.
[Samsung Galaxy S22 Ultra] neophyte1983:
Na that is not my Problem. Because of the DTM i get delayed Updates when DTM release it. EUX get it earlier then me. I hope maybe in the Future it is possible to change DTM to EUX

[Samsung Galaxy S22 Ultra] leosoftstudios:
Hello,

I am planning to change CSC on my A54 5G (SM-A546B EUX version) with SEK version via SamFW 4.x tool. My questions are:

1. By doing this my A546B model would be transformed to A546E. Is that right? Does this affect warranty and/or knox counter? And in the future, if I decide to return to my original EUX csc, this could be possible?

2. Do I have to download first the SEK (Ukraine) firmware before I start using the SamFW? or It will be automatically downloaded from within tool?

3. If I understood well, after this procedure I may lose CallerID option. So my phone will not be able to recognise who is calling anymore???

4. Currently my A546B wears PDA: A546BXXU1AWC4 and CSC: A546BOXM1AWC5 and hopefully after the modification (according to samfw.com downloads) i will have PDA: A546EXXU1AWC4 with CSC: A546EOXE1AWC4. Is it sure that I will not lose my data after this?

5. And the most important question... Does anyone tried this to the very new A54 5G ?

Thanks for your time and once again congradulation for this great thread.
[Samsung Galaxy S22 Ultra] Lifestoshort007:
Hi All,

This is a very informative thread, I have a quick question.

I am in the UK and have the following SAOMC_SM-908B_OXM_EUX_13_0135 EUX/-/EUX/EUX

I would like to enable the call recording but am not 100% which csc to change to, I would like to be able to continue using google pay and also have the samsung updates.

I am guessing the I can do this or are the EUX not possible?

Thanks in advance.
[Samsung Galaxy S22 Ultra] ChoSmile:
1. No x3

2. No

3. No

4. No

5. No

A54 SM-A546B (like A53 B model) do NOT have ANY CSC with internal Call Recording that can be switched to, so sorry, just save your time and do not try samfw or flash other firmwares.

For this model only rooted - if you find way, but Knox tripped, no warranty, no security apps, no bank apps, some games, no GPay, maybe hide root will be temporary delusion for some of the points.

If you want call recording try other 3rd party apps but if works recording will be noisy. Or change phone.
[Samsung Galaxy S22 Ultra] ChoSmile:
Only SEK CSC for your model.

GPay will work, everything will be the same (like EUX), only new OTA will be when SEK release update.

P. P.

No Samsung Pay in SEK.

These videos are for A54 5G - SM-A546E - (Asia model) .

As you said, you have A54 5G - SM-A546B - (Europe model).

Sorry, my mistake, All are Exynos models.

SM-A546V, SM-A546U, SM-A546U1, SM-A546B, SM-A546B/DS, SM-A546E, SM-A546E/DS, SM-A5460

But still can not change CSC / flash firmwares for different model.

The phones have different hardwares and different firmwares with different CSCs, can not be cross flashed.

Hi bro

one question, to enable physical dual sim and disable e-sim, any CSC that works on exynox and qualcomm s21,s22,s23

Thanks
[Samsung Galaxy S22 Ultra] ChoSmile:
Devices that have two physical SIM slots have DS after model name. So as I know there is no CSC that limit second sim or esim usage. Almost all devices have eSIM hardware (when enabled in menu it switch off physical SIM2, and vice-versa).

ESIM hardware missing in China models SM-Xnnn0

Long time ago some mobile operators request Single SIM devices from manufacturers and they are locked to this operator' SIMs. (I have no info if S21/2/3 there is still such limited devices.)

[Samsung Galaxy S22 Ultra] DaOldMan:
This looks like a usa unlocked model (xaa csc, not xxa like you write). Those don't have any csc that allows recording. You can't switch to xxv. You can only switch to a csc that is in your rom. Obviously Usa roms don't include Vietnam csc. Samfw should tell you exactly which csc you can change to.

Sorry mate.
[Samsung Galaxy S22 Ultra] ducdv:
Is there no way to enable the call recording feature on my phone? 😥
[Samsung Galaxy S22 Ultra] DaOldMan:
My guess is you have to root the phone. Then you may lose other functionality like Samsung pay, Samsung health and such. For some there are bypasses. Google pay usually can be made to work. But i an not rooted for a year now on my main device, so have no idea.

Cheers.
[Samsung Galaxy S22 Ultra] ducdv:
Thanks in advance bro. My phone could not be rooted because my wallets and banking apps. So I will try to find 3rd party software for it.
[Samsung Galaxy S22 Ultra] DaOldMan:
They can all be usually made to work. But some may not work. I managed to make them all work but it was a year ago. You should research this on xda.

You can't find any app to get good recording quality since Android 11. Google is restricting this. Only internal recording is allowed. Application will need to use your microphone to record and the quality will suffer. But that is why you pay much less for a device then others (1300$).

Cheers.

Ya, an expensive lesson. I just buy a s21 ultra US variant (I used IPhone 11 pro max before). Because I want to use some interested stuffs on Android (call recording for example) but seem a bit disappointed now.
