Samsung Galaxy S (2010)
First released in June 2010, the Samsung Galaxy S ran on Android 2.1 and had an 800 x 480 Super AMOLED display.
It also had a single-core 1GHz processor and 0.5GB of RAM.
The rear camera was 5-megapixels, while the front was just 0.3-megapixels.
Samsung Galaxy S2 (2011)
Also known as the Samsung Galaxy S II, the refreshed phone was released in April 2011 and sported a similar 800 x 480 screen as its predecessor.
The processor got a bump up to dual-core and 1.2GHz, and there was 0.75GB of RAM.
The rear camera was 8-megapixels this time, with a 2-megapixel front-facing cam.
Samsung Galaxy S3 (2012)
Again sticking with the Roman numerals, so therefore technically known as the Samsung Galaxy S III, this model came out in May 2012 and was the first in the series to have a HD screen.
Its resolution of 1280 x 720 was pretty revolutionary at the time. It also sported Android 4.0 Ice Cream Sandwich.
There was a 1.4GHz quad-core processor with 1GB of RAM on launch, although Samsung stuck with an 8-megapixel rear camera.
Samsung Galaxy S4 (2013)
Released in April 2013 and ditching the Roman numerals that nobody used when referring to Galaxy phones on the internet anyway, the S4 had a 5-inch Full HD display.
It also upped the processing power to a 1.9GHz quad-core chip, with 2GB of RAM.
The rear camera had a jump too, up to 13-megapixels.
Samsung Galaxy S5 (2014)
Coming in April 2014, the S5 also had a Full HD screen but it was slightly bigger, measuring 5.1-inches (an LTE-A model eventually upped that to 2560 x 1440).
There was a 2.5GHz quad-core processor on board, with 2GB of RAM. And the rear camera was once again improved, to a 16-megapixel module.
Samsung Galaxy S6
April 2015’s Galaxy S line was the first to offer two separate devices at the same time.
The more standard Galaxy S6 featured a flat 2560 x 1440 Quad HD Super AMOLED display, measuring 5.1-inches.
It ran on a Samsung-made octa-core processor, had 3GB of RAM and a 16-megapixel rear camera capable of recording Ultra HD footage. A 5-megapixel camera was adopted for the front.
Samsung Galaxy S6/S6 edge (2015)
Like its stablemate also released in April 2015, the Galaxy S6 edge had a 5.1-inch Quad HD screen, octa-core processor, 3GB of RAM, 16-megapixel rear camera and 5-megapixel front-facing cam.
Where it differed is that the sides of the display are curved and wrap around to give the illusion of no bezel – a radical alternative at the time.
Samsung Galaxy S7/S7 edge (2016)
The Galaxy S7 edge was (and even now it’s two years old, still is) a true flagship phone in every respect. It too was announced in February 2016 and its 5.1-inch/5.5-inch dual edge QHD display was simply superb.
All of the same features as the S7 were on board and the design was a touch rounder than the S6 edge that preceded it.
Samsung Galaxy S8/S8+ (2017)
The Samsung Galaxy S8 was the first to introduce the Infinity Display, that referred to the fact it had an edge-to-edge display with virtually no bezels. The front-mounted home button was moved to the back too, albeit in a slightly awkward position – something Samsung should correct with the S9.
While there was also a second variant in the S8 Plus, which came with a bigger screen and better battery, but the standard Galaxy S8 came with curved edges as standard
Samsung Galaxy S9/S9+ (2018)
On the surface, the S9 looks very similar to the S8 from 2017. The phone still offered that curved edge design and comes with a 5.8-inch OLED screen size and was once again, waterproof.
The Galaxy S9 also offered AR emoji, which allows the phone to create a 3D avatar by scanning your face and creating a range of custom emoji for you. These can be used when chatting in WhatsApp or Facebook Messenger, for example, rather than using basic emoji. Social.
The Samsung Galaxy S9+ also launched alongside the S9 offering a dual aperture main camera that was a step up from the previous year.
Samsung Galaxy S10/S10+/S10e (2019)
The Samsung Galaxy S10 recently launched alongside the larger S10+, the more affordable S10e and a 5G capable model.
Galaxy S10+ is Samsung’s latest flagship for 2019. It has a bright 6.4-inch AMOLED display and has a hole-punch design. While the hole-punch does sacrifice a small portion of the display, it isn’t distracting. The display is crisp and gets really bright when outdoors. Samsung has picked the Exynos 9820 to power the Galaxy S10+ and has paired it with 8GB of RAM and 128GB of storage.
