Wondering how to read Samsung Firmware build numbers? Here Are 7 Tips

Samsung Galaxy Note 20 Ultra

If you are looking to learn or check how to read the Samsung Firmware build numbers then you came to the right place. Many of you sometimes guess about the software number that you have received in your latest updates but wonder how to read them.

For example, let’s take the latest build number released from Samsung i.e – Galaxy S20 Ultra’s latest software update G988BXXU4BTH5.

Here’s how to read Samsung Firmware build numbers:

1. Starting with G988B
In the firmware version, the first G988B is the model number of the Galaxy S20 Ultra. You will see the G988F in some regions. It specifies which device is getting the update.

2. XX IN THE CODE
This XX part indicates the international or European version. Some carriers in many countries have different codes, like in the US, South Korea, and China.

3. U4 Defined as BOOTLOADER VERSION
As per the security policy of Samsung, you can’t downgrade to the lower bootloader version. Here, you are on bootloader version U4, so you can’t flash the U3 version.

4. B IS FOR ANDROID OS
The letter B is important. It shows the major update since the Android OS version. The letter A means the first update, B is the second major update, and so on. The letter Z means the beta version. When you see Z instead of A, B, C …. & so on, then that is the beta version.

5. T INDICATES AS CURRENT YEAR
The eleventh letter in the code is for the current year. In the given code T is for 2020. 2017 has Q, 2018 has R, 2019 has S and now 2020 has T code number.

6. THE NEXT H IS FOR THE RELEASE MONTH
With the letter H or the 12th letter, you will know in which month the firmware has been released. A is for January, B is for February, and so on. Here the H means August.

7. LAST 5 NUMBER SHOWS HOW MANY TIMES THE FIRMWARE HAS BUILD
To make perfect software, developers need time and effort. The last letter 5 shows that effort. With the last letter, you will know how many times the firmware was built.

I think I have covered all the letters in the firmware code. With these numbers, you can now find out the firmware version for your device. Note that, some countries like the US, always get software updates, after when all other models receive it.
