In this guide, we will help you understand the Firmware version that is currently installed on your Samsung device. Comprehending the firmware number has never been an easy task, with the OEM tending to incorporate as many details as possible in just one single value.  Right from the Android version to the security patch, region, and unique device code, there’s a lot to apprehend in one go.

And just when you thought things couldn’t get any more complicated, Samsung accepted this challenge with open arms and has given us with probably the most challenging firmware to decode. But while the initial understanding of the firmware will no doubt take quite a lot of time, however, after that, it will just be a breeze. But how?

Well, we have found a nifty method using which you could break down the entire firmware into four smaller subsections, with each having its own reserved meaning which is not going to change irrespective of the device you own or the update version [though it’s obvious that the value within each of these sections wouldn’t be the same for different devices]. So taking the help of this method, let’s try and understand the currently installed firmware on your Samsun device.

Samsung Firmware Version: Let’s Decode It!

For the sake of reference, I’ll be using my Galaxy S20 FE 5G device having the firmware version G781BXXSAHXD1. You may check for your device by heading over to Settings > About Phone > Software Information > Refer to the Build Number. You’ll have four sets of values there, in the form of Value 1. Value 2. Value 3. Value 4, you’ll have to get hold of Value 4.

For instance, in my case, the entire Build Number is  TP1A.220624.014.G781BXXSAHXD1, so the fourth value will be G781BXXSAHXD1. This is our firmware version which we will now try to understand. For that, let’s first break down the firmware into four smaller sub-sections, following the 4-3-3-3 order. This, in our case, will translate to G781-BXX-SAH-XD1.

These sections correspond to Hardware (G781), Availability (BXX), Update Features (SAH), and Build Date (XD1). The value in brackets corresponds to our firmware and will obviously be different for your device and firmware. Keeping all these points in mind, here’s everything you need to know about all these four categories.

Hardware

This is the device’s model number. One interesting thing to note is that Samsung usually reserves the last digit to signify whether the device is 4G LTE or 5G. In this regard. “0” and “5” are reserved for LTE devices whereas  “1,” “6,” and “8” are for 5G devices.

Availability

  • The first alphabet in most cases will either be B or F, with “F” denoting international LTE whereas B is for the international 5G variant. “E” corresponds to Asian markets, and “N” to South Korea. “U” is for the USA, and unlocked Galaxy devices in the United States are denoted “U1″. You might also come across “FN” and “FG” in some markets.
  • The last two alphabets [XX in my case] are associated with international and European markets. USA devices have “SQ,” and USA-unlocked devices have “UE”.

Update Features

  • The first character will either be S or U. S is just for the normal monthly security patch updates whereas U is a heavy one with tons of goodies.
  • The next character is the Bootloader version, which could be both a number as well as an alphabet. In our case, the Bootloader version is A [the order is ….8<9<A<B<C and so on]. Just keep in mind that you cannot downgrade from a higher bootloader version to a lower bootloader version firmware. So you cannot downgrade from 8 Bootloader version Firmware to 7, A to 9, or C to B but you can downgrade from 7 to 8, 9 to A, and B to C.
  • The final [third character]  denotes how many major One UI as well as feature updates a device has received. Every device starts with the letter A and in our case, it is currently on H, so it signifies that it has received 7 updates till date.

Build Date

  • The first character in this section represents the date when the currently installed update was released. In this regard, U stands for 2021, V for 2022, W for 2023, X for 2024, and so on. In our case, it’s X, which is 2024.
  • The second character signifies the month, with A being January, B February, and so on [in our case, it’s D, signifying April]. So if we combine these two characters, we get XD, representing that the currently installed update is of April 2024.
  • The final character is a Build Identifier and starts from A or 1 and increases one value until a major feature update is released, at which point the cycle gets reset and again from 1 or A.

So on that note, we round off the guide about the Samsung firmware version. We tried to be as detailed as possible and explained each bit of data in detail. However, if you still have any queries, then do let us know in the comments section. We will get back to you with a solution at the earliest.
