I change CSC to ILO and record call working good but my samsung calendar marked Friday and Saturday as a weekend day. Is it possible to changed weekend days colors?
it's a ILO CSC configuration so if you are not rooted you can't change it
if you are rooted change XXXXBRX to XXXXXXX or delete the line
you can change your CSC to INS SEK SLK THL or XXV
Hello..I am in confusion between buying the international version or the UAE version. I am currently in UAE.
Is automatic call recorder supported in these versions? Or I should change my CSC using samkey?

S23, S23+ and S23 Ultra in UAE are sold International versions SM-S911B, SM-S916B and SM-S918B with XSG CSC - which is for UAE. The CSC of these SM-S91*B devices can be changed* to INS, THL, XXV, ILO, SEK,... to enable internal Call Recording feature.
* via SamFw (free) or SamKey (paid).

Do changing CSC to these countries affect signal reception or 5g bands?
My galaxy watch 5 is UAE version, does it affect pairing with phone if I change CSC?
Thank you
No. On my phone everything works fine. And also can be changed unlimited times.
S9080 can use China firmware (CHC) to get call recording, but no Google services.
S908N (Korea) has call recording in all CSCs (KOO, KTC, SKC, LUC).
I quoted you several times on this matter already, but you keep telling people otherwise.
Ok, I'll take a note!
But I personally do know someone how will switch to CSC for Call Recording on "price" to lose Google Services. So, no reasonable option for "0" model.)
For N model CSC change is forbidden by Samsung. Even all N CSCs has Call Recording, people not interested because of it.
Do no update to S91*BXXS2AWEA
The firmware is not signed by Google Play Protect - so phone become UNCERTIFIED and Google Pay stops, other SafetyNet dependent also.
At the moment only THL CSC is pushed to ...WEA. Others (at the moment) are on WD1.
TThe is nonoption to downgrade because this is first firmware with new 2 bootloader.
Deleting, Unistalling, Clearing data, even Factory reset do NOT avoid uncertified status.
(There is a chance for updating Play Protect but it's less likely before Samsung new firmware.)
Current option for already updated to WEA:
Just wait for new WEx (after A) or WFx firmware.

You can use the samfw tool without resetting the phone. I did change mine from EVR to THL and everything is working. Good luck
yes, it has trojan. I'm on XXV already have call recording. Last week I intended to change to INS to have callerID and spay, but after downloading SamFw Tool, I think I'm still on XXV
I add attachment SamFW v3.1 which is clean and works with S22 and S23 without any problem.
Argh already did the update and after the first 3 payments it's now blocked...
If you manage to get it to work please let us know!
Feel your pain - changed csc the same day (just after) the csc was released. Phone had been great til then too 
Choices:
- Тhe realistic solution to the problem is new/next Samsung firmware. (this month)
- Тhe less likely solution is a new Google Play Protect (never happens, or not before next samsung fw)
- Donwgrade to "cerified" firmware version. Only if possible - means older fw is same bootloader version. (Currently S23* not possible, S22 is possible.)
-Other software fixes are most likely to trip knox or to brick phone. (These fixes are mostly made for rooted phones to deceive Play Protect that "device is not rooted". I never saw such fix working on device that do not have root access to install it.)
for N models, they used to be able to change CSC. I personally did it on my G981N from KTC to KOO to remove Korean bloat. But it was blocked some time in 2021 I think.
It was possible again with the System Shell Exploit (no Knox trigger), but it was patched I guess.
Also, one interesting thing I just observed. I got the S918B Australian model (XSA CSC), with single physical SIM and eSIM.
After changing CSC to XXV (or any markets with dual physical sims), it becomes S918B/DS.
I am ordering a dual sim tray from Aliexpress to check if this really enables dual physical SIMs for S91xB (no DS) models.

Just to add that i've just found out that in my region is not necessary to change CSC anymore.
For S23, using Brazil Retail (ZTO) now i have callrecording, hiya and spay from factory.

Really?!
Why does everyone need specially and personally made instructions?! It has been explained in this thread several times. A simple youtube search (samfw csc change) shows even a visual.
If you do not want to mess-up DO NOTHING !!! -

Yes , I used samfw for first time in my s23 ultra. The procedure is very easy and safe. I tried INS but then I changed to SEK for the reasons I explained before.
In short:
1. You enable ADB in your phone
2. You download samfw to your windows PC and run it.
3. Connect your s23 ultra with the PC through a cable.
4. Run samfw , and press Tab adb in the program (it is the third tab in the upper place of the app).
5. You will see a pop up menu with all available XOM multi- csc .
6. Choose and right in the appropriate box the one you want (INS ,SEK etc).
7. Press "change csc"
8. It will appear a prompt saying dial *#1234#* (or something like that ) while the screen of your phone is looking like being in check mode( like the one you have in Samsung Member app when you want to make a check for some function).
9. That's it. In seconds you have your new scs without data wiped!7
