Samsung Build Number Explanation: How to Decode

Published

on


Samsung is the largest smartphone manufacturer in the world at present. It received this status via having a vast & varying range. Samsung issues regular updates to its devices in four parts, i.e., monthly, quarterly, bi-annually, and yearly. These updates depend upon the recently updated Samsung’s Fours Year Software Support Policy. But that’s a subject for another time; today, we are going to explain how you can read the build no. of the updates known as firmware identifier or build no.

Samsung Build Number:

If you are a Samsung device user, you must have noticed that the different update on your smartphone brings different serial no./build no. in the changelog, aka your updated notification. We are sure many of you will be curious to know how what & why of that update, meaning just what changes the update brings and how to read them. So that is what we are exactly doing. Fasten your belts because it’s going to be a little confusing at the beginning. Still, we are sure once you get hold of it, you will become an expert at reading the firmware numbers.

How To Decode Samsung Build Number:

So there are four sections of a build number, all but one divided into three parts. Starting with the first segment, we will take an example from the Galaxy S22 series of a Galaxy S22 Ultra Asian variant with build no. S908-EXX-U2A-VF9

  • First Segment Device Information Section (DIC); We will dub this section the Device Information Section (DIC), consisting of the first four letters. 

First Letter; Let us start with the first Letter. The first Letter, e.g., S denotes the device’s series name; here, it will be an S series device. Below is a list of series represenattaionby letters; 

Note: The ‘G previously denoted the S series,’ so don’t be confused if you come across an older device’s Letter.

  • N – denotes the recently canceled Galaxy Note series.
  • S – This is the flagship Galaxy S series.
  • F – Clamshell foldable Galaxy Z series occupies this alphabet.
  • E – Mid-range Galaxy F series.
  • A – Starting-Mid range A series.
  • M – Entry-Mid level M series, most popular in Asian and Indian countries.

Second Letter; 3 represents price range, e.g., S908- 9 here denotes the flagship devices, and then it further decreases to mid to entry-level range, following with 7, 5, and 3, etc. Here in S908, nine is to represent a high-end device in terms of price. For a Galaxy S21, its starting second will be 9 as in G99.

Third Letter; this Letter represents the generation of the device, i.e., how many series generations have been released till now, usually following a yearly pattern. Let’s take S908– then it’s the new hybrid of the Note and S series; thus, it has ‘0’ in the Letter. For an S21, it would be the 9th generation of the device.

Fourth Letter; This represents the display size of the device but there is a catch; ‘0’ and ‘5’ are for LTE/4G, and 1,6 and 8 are for 5G devices. For example, a Samsung Galaxy Z Fold3 5G would consist of 6 in the fourth Letter across all variants.

That concludes our first section. Let’s move on to the second;

  • Second section or Region Details (RD) of the device; We take an example of a Galaxy S22 Ultra with the EXX in the second constituting 3 letters. Let’s start with the first.

Fourth Letter; It represents the region for the different regions; there are different alphabets. They are;

  • F & B; Global versions with F being LTE & B being the 5G.
  • N; Reserved for S.Korea.
  • E; Asian markets.
  • U; the USA, U1 for unlocked, and U for the carrier’s locked networks such as T-Mobile, Verizon, etc.
  • FN & FG; these are region-specific codes which represent.

Last Two Letter Of Second Section: The two last two letters denoted by XX contains even further information about the device region, i.e. XX would be European or Global variant. Usually, it’s the European model we see associated with XX.

However, if the device belongs to the USA, these two Alphabets would be changed to SQ for locked models and UE for unlocked variants. Let us understand by an example, take Galaxy Z Fold 3 with firmware no. F926USQ here for locked the alphabets would be replaced by UE for an unlocked model.

Section Three or Device Software Information:

This is the device software information center, you can know about what the update brings in these three letters.

The first letter; will always be either a U or an S, with S representing only security patch and U representing Patch + updates with additional features like apps, system tweaking, visual improvements, etc.

Second Letter; This letter can change, which represents the Bootloader version i.e. the basic input and output system responsible for the startup or system initiation. If we take an example of U2A here 2 will represent the Bootloader version, that would be the second build and this cant revert back it will always be in numerical progression or remains unchanged.

Third Letter; This is an alphabet that changes and is related to the OneUI upgrade and how many versions of the OneUI the device has received. The alphabet will change in progression wrt the OneUI version.

Fourth Section or Device Software Time Information:

This section deals with informing the Time related to firmware development, yearly and monthly.

First Letter; Let us take an example of VF9 as the last three letters. The V here is the year of firmware development, with U being 2021 so if it progresses here V will be 2022 and continue further. 

Note; However, this could also show the OS version for newer smartphones.

Second Letter; It represents the firmware completion month, A is considered as Jan so F here would be June, however, this does not always coincide with the time meaning the version could be older but with the release next month.

Third Letter; This deals with build identifier and is a Letter or a digit, meaning it always starts with an A or 1, e.g. 9 with the 9th build. However, it also doesn’t coincide always. 

We tried to simplify this information, but that’s it for now, we will keep you updated for more of this information.

Samsung Boost Exynos GPU & Hiring Developers In The US & India

Published

By


Samsung Electronics is concurrently hiring developers in the U.S. and India regions to energize its graphics processing unit (GPU) technology capabilities. 

The Korean Electronics firm stated that it is pursuing talent in several positions, from GPU design to performance advancement, graphics drivers, and application processor (AP) software development, including GPUs. 

The Korean brand is hiring developers at its R&D centers in Austin (SARC) to support its graphics processing unit technology. They are located in Austin, USA, where Samsung Electronics’ R&D center is located (SARC), San Jose (ACL), and Bengaluru, India (SSIR). The aim behind this decision appears to be to upgrade the overall performance of their application processors (AP) by concentrating on the GPU technology within them. 

A semiconductor industry official stated that “the Exynos portfolio of GPUs equipped with GPUs is expanding not only for high-spec but also for mid-to-low-end smartphone APs and automotive APs,” plus “the importance of GPUs for processing high-volume data is gradually expanding.”

Samsung Electronics has not developed its GPUs yet, although its Semiconductor Business Division (DS) GPU development team has partnered with SARC· ACL· It is a part of SSIR and is currently in charge of optimizing GPUs for smartphone APs. GPUs developed in collaboration with AMD are being applied to mobile applications. A few years ago, in 2022, the first AMD GPU named ‘Xclipse’ was installed in the Exynos 2200 chipset. 

Although issues with heat generation as well as performance limitations were boosted along with the Exynos 2200, Samsung has since stepped up its development to regain the reliability and competitiveness of the Exynos. It is expected that the GPU development team at Samsung could work with AMD on next-generation GPU development and performance optimization.

Samsung Galaxy AI Features Not Stay Free Forever: Will You Pay for It?

Published

on


Experience your Samsung Galaxy AI while you can, since they won’t be free forever. Samsung earlier this year introduced a powerful package of AI features named ‘Galaxy AI’ on the Galaxy S24 series and later expanded it to other Galaxy flagship devices. 

Samsung Galaxy AI Features Not Free

The Samsung Galaxy AI package includes multiple features such as Circle to Search, Chat Assist, Live Translate, generative wallpaper, and many more for enhancing the users’ experience, but unfortunately, they are no longer available for free. This is being speculated on in an official statement. 

On the official Galaxy AI page, Samsung mentioned in the terms and conditions section that “Galaxy AI features will be provided for free until the end of 2025 on supported Samsung Galaxy devices. Different terms may apply for AI features provided by third parties.” 

By this statement, it’s pretty clear that these Galaxy AI features are only available for free until 2025; after that, it will start asking for charges for using these novelties. However, the brand has not yet mentioned or unveiled how much it will cost or if it will offer plans for it. 

Somehow, the statement mentioned above pointed toward two notes: the first is that maybe the Korean giant is planning to support and upgrade Galaxy AI going forward, possibly adding new features alongside the next-generation Galaxy S25 in 2025, and the next is that after this year, when your base has grown and become established and some of you have grown comfortable with features like Translate, the trap will spring. 

On the other side, Google is also expected to charge for access to generative AI features, such as Gemini. It is just one part of Google One and has already offered both free and paid tiers. Along with the free tier, users can access 60 requests per minute and perform a wide range of image as well as text tasks. Whereas, with the paid tier, users have the power to access more than 60 requests but are charged $0.000125 per 1k character and $0.0025 per image. 

Here’s the question: Do people pay for the Galaxy AI features? 

Galaxy AI includes various features that are divided into two categories: one that works offline (live translation, chat translation, style and grammar, and more), and the second that requires an internet connection (summarize for Samsung Internet and more). If the brand asks for charges for AI features that don’t even require an internet connection, it’s pretty hard to believe users will agree or be interested in paying for them. On the other hand, if the brand charges for the Galaxy AI features that require an internet connection, there is quite a high chance that premium users will agree to pay. 

Why is Samsung looking forward to asking for charges to use the Galaxy AI features? 

In a way, Galaxy AI features are using different servers; for instance, Google for Circle to Search features. This means that Samsung should pay Google and another server provider, so maybe that’s the reason why the brand is looking forward to asking for the charges for Galaxy AI features. 

However, Samsung behind this decision has not revealed any reason officially yet, but it will be interesting to see what new changes it will introduce and how much it asks to pay for using Galaxy AI.

Samsung debuted a digital wallet application named ‘Samsung Wallet’ a couple of days ago, on March 20, in place of the Samsung Pay app in its home country. Within a few days, it made its reach significantly. 

Samsung has disclosed the matrix of the newly launched Samsung Wallet, according to which, within countable days, 70% of people who were using Samsung Pay on their Galaxy device have updated the older app to the latest ‘Samsung Wallet’ as reports are unveiling. 

Apart from this, the Korean giants have also stated that the ratio of Samsung Pay users aged between 10 and 20 who updated the application to Samsung Wallet was even higher, 75%. Somehow,  this appears to be a direct result of the brand’s promotion that has been running for those people. 

In South Korea, Samsung Wallet supports the Mobile Driver’s License and Mobile National Veterans Registration Card, which even have the’same legal effect as real ID cards.’ and are also permitted to be ‘used for voter identification purposes in public institutions and financial institutions that require identification, as well as in the 22nd National Assembly election on April 10.’

On behalf of this latest significant achievement, a Samsung official stated that’ “Samsung Wallet’s various additional features are rapidly changing users’ daily lives. We hope you will experience the era of electronic wallets that have become safer and more convenient with various lifestyle features.”
