Samsung’s firmware updates for devices come with different versions for countries or regions, calledCSC, which stands for Country Specific Codes. There are two sections, PDA and CSC, for each firmware, which affect some features and settings of the device.
PDA: This contains the build number with global Android system changes.
CSC: This contains country-specific wallpapers, Wi-Fi calling, VoLTE, and sounds.
This means that theCSC code determines the compatibility of our Galaxy device,and it’s important if you want to flash your device’s firmware. Make sure that if you download the wrong firmware update file, it could cause problems, so you must know the CSC code before you download the firmware update file.
