What Does Each Number in Samsung Firmware Mean

What Does CSC Stand for?

CSC really stands for country-specific code, and in the Android community, it is paired with Samsung Galaxy devices.
Samsung creates dissimilar software for unlike countries, so in order to upload the software ourselves, nosotros need to know what our firmware is. This can sometimes get across designating a code for a specific country, though. For example, the US sounds like an obvious CSC region lawmaking for Samsung smartphones sold in the US? In fact, the company tin can sometimes suspension down these larger markets into cellular carrier-specific firmware images. And in fact, major devices sold in the U.s. carry the CSC Verizon Wireless (VZW), T-Mobile (TMB), and AT&T (ATT) region lawmaking (amid others). The aforementioned is true in Europe, apart from the land’s CSC, there are likewise local CSCs of mobile operators. All phones of a given model have the same model number simply have different CSC region codes because Samsung makes special firmware for mobile operators (in some countries). Nearly important all OTA update employ CSC region code to check if your Samsung device is approved for a new software update with a new Android or security patch.

How Can I Detect My CSC Region Code?

To check what CSC region code got in your Samsung Galaxy device go to:

1. Settings carte.
2. About phone.
3. Software information.
   
   
4. And look for the “Service Provider SW Ver.” section.
   
   
5. Hither is the three-letter CSC code for your Samsung device.

For example, in our Samsung device, we got:

AUT
/AUT,AUT/
EUY
/AUT.
I will break it down into prime factors to indicate what every particular ways in the CSC code.

Agile CSC
/SIM one,
SIM 2
/
Region

Primary CSC

Nosotros use a Swisscom sim-bill of fare and for this sim-menu, we should get SWC CSC lawmaking why we got AUT?
Simple CSC code is sim-card independent and the telephone is from the open up market not from the operator considering this, nosotros take multi CSC in our Samsung device EUY/EUY/EUY/EUY/EUY. After inserting to it Switzerland sim-carte this change from multi CSC to our country open market place CSC code mean
AUT/AUT/AUT/EUY/AUT
and this was master CSC setting only was subconscious. If a device is from a Swisscom operator after outset connect to the internet and become data from the Samsung server, CSC in it will alter to
SWC/SWC/SWC/EUY/SWC
what means that the device should get only the OTA update with customisation for this cellular network. Something more than about the EUY notation. What does it mean exactly? This information is that the phone is intended for the countries exterior the European Economic Area – EEA.
