This is just a question about Why does Samsung use different CSCs for different Countries? Not about a guide or how to
I have owned Sony, Oneplus and other different brands of smartphones, neither of them use the CSC "system", it is just 1 version of the software or the update that get pushed to all phones in different countries at the same day.
This is just a question for discussion.

the diff bloat included i guess
That's a very good question. Samsung makes special firmware for mobile operators in some countries to take advantage of all the Call Features and 5G support the Service Providers offer. It also leads to a lot of complications if you move to a different region, switch Service Provider's or aquire a device from a different region. It's ridiculous, Samsung offers 27 different S21 Variants. On top this add in all the different Carrier Branded Devices. That might push the total to 100 or more variants. Then when you think it can't get any worse they offer multiple chipsets adding further to the confusion. It's an absolute mess!

I'm considering buying the note 8 but in terms of community support which version (if any) is better supported or is it to early to tell?
My last phone was the S5 - SM G900i and while it was good most roms were generally made for the f variant. the f variant roms worked ok but always caused issues with nfc which i could work around generally by disabling nfc. I'd like to avoid that situation this time around and I plan on keeping this phone for a few years.

Exynos single sim in general gets the most... but can you disclose where do you live? As that would be major factor.... if Europe then UK unlocked model brings theglory in general...aka exynos single sim.
The 950F and 950N are identical hardware, but all the ROMs are being developed with the F firmware base, which seems to be set up as dual SIM at the software level (F contains the dual SIM RIL libraries while the N does not).
Right now the only real consideration between those two is internal storage since I think the 256gb model is only available as N variant.
The HK 256gb is Snapdragon.

I live in New Zealand. The most common variants ive seen are the sm-g9500, sm-g950f and the sm-g950fd. There are also some usa sm-g950u available through eBay.
Of these the fd variant is the cheapest and fairly easy to import. Local version seem to the f and 9500 but the local versions are generally about $400 more expensive.
I am not to worried about importing and the warranty issues. I've never had hardware issues with Samsung phones and even if I did I'd get it repaired locally and it would still be cheaper.
For the US versions, does the unlocked version and carrier versions all have the same amount of support for bands as I heard the hardware was all the same and it's just the software that is different on the carrier variants. Basically, if one uses Verizon Wireless, can one purchase the T-Mobile or the unlocked model or even the Verizon Wireless model of the Note8 and have the same bands enabled on the phone so it works well when traveling using a pre-paid SIM or is the unlocked model going to offer more band support as it seems Samsung doesn't list the actual band support on the models.
Hi!
So I've bought a Samsung S9 Duos recently and to be honest, although I like the phone and have been on a Samsung streak for the past few years, I'm getting seriously tired of their country dependant shenanigans. Because I live in Canada, when I buy a Global phone there's a bunch of stuff that either doesn't work or does only partially. And because the Canadian model is a SD proc, not an Exynos, it's an absolute nightmare to switch CSCs and get everything working right...
I hesitated long and hard to get a P20 pro, but the fact it wasn't available anywhere in Canada made me nervous. But my carrier (Rogers) recently announced it so, being really tired of this Samsung ****e, I'm considering returning the S9 and getting the P20 pro (even if it doesn't have a lot of stuff I like such as the headphone jack, SD card and wireless charging).
TL;DR
My question is, if I get an international (dual SIM) model of the P20 pro, is it going to be different than the Canadian one? Is there an equivalent of CSC codes with Samsung that I have to worry about, or can I assume it will be the same phone and I just need to activate it to get carrier specifics?
Thanks
I'm not an expert, but before I bought my P20 Pro, I made sure that it worked with the AT&T's network frequency bands. Each network has different bands and if the phone doesn't support the band, it won't connect.

Thanks for the input. I checked the bands for sure, and they are covered since it will be sold on my carrier soon. I guess what I meant is more the model itself, if there are variants per country or if we (Canada) are getting the same global version.
You see I come from a Samsung user's background and they have these silly country codes that dictate what you can use and where. I'm not sure it's related, but I found that even if on paper all LTE bands are covered with my S9, it still has shoddy reception compared to a Canadian S7. I could try to flash my CSC code to the phone, but a) it's complicated and risks bricking the phone and b) since the Canadian model is NOT the same as the global one, my CSC cannot be applied to this phone no matter how hard I try...

FunkyHuawei offers a rebranding tool, which changes the region of the ROM. I used it because I bought mine from a Chinese e-commerce website. I rebranded to European region.
I couldn't find anything about International or Global versions of the phone. I know they are region locked, but the rebranding tool will fix that. You can also flash a firmware from FunkHuawei or use HuRUpdater tool from TWRP custom recovery.
I have used both tools, and had 100% success.

Cool thanks, I'll see how this could help me out. I'm giving my S9 one last chance but short of that, I'll cough up another $1000 for this phone; I just don't want to end up in the same trap!
Hi,
I was given a Note 9, international, with dual SIM to test at work. It's quite different than the Pixel 2 I'm used to and although it's a great phone, I know updates are not great with samsung.
The current version I am on is N960FXXU1ARG5 and AIDA64 tells me this is an SM-960F with Exynos5 CPU.
When I look on sammobile, I don't see a region called Canada, United States, North America or even International.
Having multiple firmwares available is a bit more complex than with a Google Pixel and I'd like to make sure I don't mess up the Note 9.
Is there something I can do to be in a "region" that's perhaps more likely to get updates?
What "region" is considered the "international" region.
What firmwares would be safe to flash with Odin and that would be better than this stock firmware (if any)
Thank you
I bought a Galaxy S20 FE 4G (exynos) in Mexico with Telcel carrier but they are very slow on pushing updates. I see on firmware sites that almost monthly there's a new update which I don't get.
My question here is, if I flash via Odin a ROM from a different region will it affect the usability of my phone on something?
If it doesn't, which region has the less bloated ROM that I could flash? I am currently on TCE's CSC.
Thanks for the help.
No, it should not affect anything, at most it may affect your ability to have VoLTE/VoWiFi as some carriers tie it to the CSC though I have not had that issue here in Australia using it with a Telstra SIM (I switched from XSA to THL and still have full functionality as before, even a couple of extra features). Although from what I can see on SamMobile there's not really a better CSC for the multi CSC you have (OW*), the updates are all pretty terrible for the CSCs with some CSCs not getting updates in months and some being one or two months behind in terms of security patch, so it may not be worth switching anyway.
Hi all. I have the a few sm-g998b phones, rooted with magisk, and I am a bit confused about which CSC I should flash to the device (SAMKEY). I ordered the phones from Singapore and need them be more compatible with USA verizon and USA tmobile. Only using one sim per phone. Which CSC should I replace the current SIN csc with for each, and is there anything else I can do to make these phones play a bit nicer in the USA? I am currently having issues with no 5g, poor wifi calling, no updates, etc.
1. Avoid SamKEY. Do your own work.
2. Flash the HOME_CSC, or the CSC of the firmware of the carrier. HOME is usually a safer bet though.
You're going to have issues in the US until you flash the proper CSC. AFAIK, every S21U has all radios, but the CSC activates the correct one.
For the absolute safest, download the TMOB stock firm, and flash the HOME_CSC (as well as the BL, AP, etc), then put the Tmob SIM in after boot.

Tmobile or any US firmware can't be flashed on any Exynos Global device.

Why would you aquire the Exynos Global variant knowing your service provider isn't optimized for your firmware? Did you save money? If so I hope saved a lot otherwise it was a poor choice. Your best option is keeping the stock SIN Firmware, at least you'll get timely updates. You MIGHT get Wifi Calling and VoLTE enabled but forget about 5G and Carrier Aggregation.
Missed that you mentioned an Exynos variant. Yeah, you're ****ed. Exynos is not compatible with US bands, or at least aggregate banding.

Unfortunately, these phones are company. we needed root for some applications.
*don't use SAMKEY
This is a bit tricky because US is Snapdragon-based.
My best bet would be to factory reset (don't forget to backup) and flash a multi-csc Exynos ROM (OXM). This would detect the most compatible one for your US sims.
I would suggest getting the XSP for Singapore because that's the unbranded one.
Other than n71 5G band for US Cellular, I don't think you'll have much issues.

"This would detect the most compatible one for your US sims" Nope, that's incorrect, Exynos Global variants aren't able to detect the most compatible US Networks. It's apples and oranges, there is zero integration for US devices.

Thanks for correcting me. Least that's how it was for me using NZ sim on a G9980 SD variant.

The Exynos variants are Multi-CSC Devices, mainly for Europe, not for the US. The SM-G9980 isn't a Multi-CSC Device unlike some US Models, it's Dual-Sim. In Settings under Network Operators you can have the device select the "Best Network" but it isn't analyzing call features, it's only matching the network with the Active CSC (SIM Card).
Bro,
On the stock phone dialer key in
*#2263#
You will see the bands the 998b supports.
Now u need to check on the networks u plan to use in the US what bands are used. Not sure what u plan to do but these exynos phones should be able to roam into the US with voice n data services. Not blazing gigabits but one should be able to roam globally with these phones.
