Samsung Galaxy Series Explained: Which One Should You Buy?
Samsung Galaxy phones are split into clear series. The Galaxy S series is the flagship line, the Galaxy Z series is foldables, the Galaxy A series covers budget to upper mid-range, the Galaxy M series focuses on big batteries and value, and FE (Fan Edition) models bring flagship features at a lower price. Within each series, a higher number means a newer or higher model.

Galaxy S series: Samsung's flagships
The Galaxy S series (Samsung Galaxy S phones) is Samsung's main flagship line, updated every year, usually in January or February. Each generation has three models: - Base model, such as the Galaxy S25 (Samsung Galaxy S25): compact flagship - Plus model, such as the S25+: bigger screen and battery - Ultra model, such as the Galaxy S25 Ultra (Samsung Galaxy S25 Ultra): the best cameras, a built-in S Pen and the largest screen
The generation number jumped from S10 to S20 in 2020, then S21, S22, S23, S24 and S25. Recent S models get long software support; Samsung promised seven years of OS and security updates starting with the S24 series.
Galaxy FE: Fan Edition
FE models, such as the Galaxy S21 FE 5G and Galaxy S23 FE (Samsung Galaxy S23 FE), take the look and many features of the S series and trim a few things, such as the chipset tier, build materials or camera, to lower the price. They are a good choice if you want a Galaxy S experience, including a telephoto camera and flagship-style software, without paying for the latest base S model.
Galaxy Z series: foldables
The Galaxy Z series (Samsung Galaxy Z phones) has two kinds of foldable: - Z Fold: opens like a book into a small tablet, good for multitasking and reading - Z Flip: folds like an old flip phone into a small square, good for style and portability
The numbers show the generation, such as the Galaxy Z Fold 4 and Galaxy Z Flip 5 (Samsung Galaxy Z Flip 5). Foldables need a bit more care with the inner screen. See all foldable phones (Foldable Phones).
Galaxy A series: budget to upper mid-range
The Galaxy A series (Samsung Galaxy A phones) is Samsung's best-selling line in Pakistan. The second digit tells you where a phone sits: - A0x (A05, A05s, A06): entry level, basic needs - A1x (A15, A16): budget, with AMOLED screens on newer models - A2x and A3x (A25 5G, A35 5G): mid-range, better cameras and build - A5x (A55 5G): upper mid-range, metal frame, the best A-series camera - A7x (A72, A73 5G): older upper mid-range models; Samsung stopped this line after the A73
The 5G label marks the 5G version where both versions exist, such as the Galaxy A15 and Galaxy A15 5G. Our comparison Galaxy A55 vs A35 (Samsung Galaxy A55 vs Galaxy A35) shows how close neighbours differ.
Galaxy M series: battery and value
The Galaxy M series (Samsung Galaxy M phones) was created for online-first markets. M models often share parts with A models but focus on large batteries, such as the 6,000mAh cell in the Galaxy M34 5G and Galaxy M54 5G. They are a good pick for buyers who want long battery life and do not mind a slightly simpler design or camera.
Exynos vs Snapdragon
Some Galaxy S models use different chipsets in different regions: - Galaxy S22 and S22+: Exynos 2200 in Europe and some other markets, Snapdragon 8 Gen 1 in others - Galaxy S23 series: Snapdragon 8 Gen 2 for Galaxy in all regions - Galaxy S24 and S24+: Exynos 2400 in many regions including Europe, Snapdragon 8 Gen 3 in the USA and some other markets - Galaxy S24 Ultra: Snapdragon 8 Gen 3 for Galaxy worldwide - Galaxy S25 series: Snapdragon 8 Elite for Galaxy worldwide
Both chips are fast for daily use. Snapdragon versions have generally been preferred for efficiency and gaming, which is one reason buyers ask about the variant.
Reading Samsung model codes
Samsung model numbers look like SM-S928B. The letters and numbers tell you the series and generation, and the last letter usually shows the region: - B: international version, often dual SIM, sold in Europe, the UK, the Middle East and Asia - U or U1: US version, usually single physical SIM plus eSIM - N: South Korea - 0: China and Hong Kong - E: older international versions in some Asian markets
You can find the model code in Settings > About phone. If dual SIM matters to you, check the variant on the model page or ask us before ordering.
One UI, updates and Galaxy AI
Every Galaxy phone runs One UI, Samsung's version of Android, so the menus and features feel familiar whichever series you pick. The difference is how long each phone is supported and which extra features it gets: - Galaxy S24 and newer flagships: up to seven years of OS and security updates, plus Galaxy AI features such as Live Translate and Circle to Search - Galaxy A55 5G and A35 5G: several years of OS updates and security patches - Newer budget models such as the Galaxy A16: Samsung has promised longer support than older budget phones received - Older models: fewer remaining updates, so check before you buy
If you plan to keep a phone for four years or more, a newer model with longer update support is usually worth a little extra. Samsung lists the update policy for each model on its website.
Which Galaxy should you buy?
A simple way to choose: - Best camera and S Pen: Galaxy S24 Ultra (Samsung Galaxy S24 Ultra) or S25 Ultra - Compact flagship: Galaxy S24 or S25 - Flagship feel for less: Galaxy S23 FE - Best mid-range: Galaxy A55 5G (Samsung Galaxy A55 5G) or A35 5G - Budget: Galaxy A15 or A16 series - Big battery: Galaxy M34 5G or M54 5G - Something different: Z Flip or Z Fold
