In 2010, the world was a very different place. Steve Jobs was still on stage, and the iPhone 4 was the "it" device that everyone obsessed over. Android was the scrappy, slightly ugly underdog. Then June rolled around, and the Samsung Galaxy S 2010 arrived. It didn't just join the race; it actually shifted the entire trajectory of what a smartphone could be.
Before this, Samsung was just another player throwing spaghetti at the wall. They had the Omnia, the Jet, and various "Behold" models that were... fine. But the Galaxy S was different. It felt like a declaration of war. It was thin. It was plasticky, sure, but it had a screen that looked like it was from the future.
Honestly, looking back at the Samsung Galaxy S 2010 now feels like looking at a vintage car that still has a weirdly fast engine. You can see the DNA of the modern S24 Ultra in its bones. It had the Super AMOLED display when everyone else was squinting at washed-out LCDs. It had a dedicated GPU. It basically taught Samsung how to win.
The Super AMOLED screen changed everything
If you held a Samsung Galaxy S 2010 in your hand back then, the first thing you noticed was the color. It was almost aggressive. The 4.0-inch screen (which felt massive at the time, believe it or not) used Samsung's first-generation Super AMOLED technology.
It was vivid. The blacks were actually black because the pixels literally turned off. That's common now, but in 2010? It was sorcery. While the iPhone 4 was winning on resolution with the Retina Display, Samsung was winning on contrast and "pop."
The resolution was a modest 480 x 800 pixels. Sounds tiny, right? But for the era, it was sharp enough to make browsing the web feel like a real desktop experience. People complained about the "PenTile" pixel arrangement—a layout where pixels share sub-pixels—claiming it made text look a bit fuzzy around the edges. They weren't wrong. But when you played a video or looked at a photo, nobody cared about PenTile. They just saw those deep, saturated colors.
Under the hood: The Hummingbird era
Samsung didn't just buy parts back then; they were already building their own silicon destiny. The Samsung Galaxy S 2010 featured the S5PC110 processor, later rebranded as the Exynos 3 Single. At the time, we all called it "Hummingbird."
It clocked in at 1GHz.
That single core was doing a lot of heavy lifting. What made it special compared to the Snapdragon chips found in the HTC Desire or the Nexus One was the PowerVR SGX540 GPU. It was a beast for mobile gaming. While other phones would stutter when trying to render 3D graphics, the Galaxy S hummed along. It could actually decode 720p HD video without breaking a sweat, which was a huge selling point for media junkies.
Samsung paired this with 512MB of RAM. By today’s standards, that wouldn't even open a single Chrome tab. In 2010, it was enough to run Android 2.1 Eclair with the first iteration of TouchWiz.
Let's talk about TouchWiz for a second
We have to be honest: the software on the Samsung Galaxy S 2010 was polarizing. TouchWiz 3.0 looked a lot like iOS. The colorful icons, the dock at the bottom—it was a blatant "tribute." This eventually led to years of legal battles with Apple, but for the average consumer in a carrier store, it felt familiar. It made Android less scary.
However, it was also buggy.
GPS issues plagued the early units. You'd be driving, and suddenly the phone thought you were in the middle of the ocean. It took several firmware updates to get it stable. And the file system! Samsung used something called RFS (Robust File System) which caused "lag spikes" that became legendary in the Android community. Enthusiasts ended up creating "lag fixes" that involved repartitioning the internal storage to use the EXT4 system instead. If you were a power user back then, you spent your weekends on XDA Developers flashing custom ROMs just to make the phone snappy.
The hardware design was... controversial
The Samsung Galaxy S 2010 was incredibly light. It weighed just 119 grams.
To achieve that, Samsung used a lot of plastic. The back cover was a thin, flexible piece of glossy polycarbonate with a "moti" pattern that looked like little dots under the surface. Critics called it cheap. Compared to the glass and steel of the iPhone 4, it definitely felt less "premium."
But it was durable. You could drop a Galaxy S, the back cover would fly off, the battery would pop out, and you’d just put it back together and keep going. It was a tank in a plastic suit. Plus, you had a microSD card slot and a removable 1500mAh battery. Those two features alone made it the darling of the "anti-Apple" crowd for years.
The camera was another highlight. It was a 5-megapixel sensor that, frankly, punched way above its weight class. It didn't have a flash—a weird omission that annoyed everyone—but in daylight, the "Touch Focus" and the sensor's dynamic range were impressive. It was one of the first phones that made people realize they could leave their point-and-shoot cameras at home for casual trips.
Why it was actually four different phones
If you were in the US in 2010, you didn't just buy a "Galaxy S." You bought a variant. Carriers back then had a weird amount of power, and they forced Samsung to change the design for every network.
- AT&T had the Captivate: It was blocky and rugged-looking with a sliding battery door.
- T-Mobile had the Vibrant: This stayed closest to the international design but lacked a front-facing camera.
- Verizon had the Fascinate: This one replaced Google Search with Bing. People hated that.
- Sprint had the Epic 4G: A chunky beast with a slide-out QWERTY keyboard and a dedicated camera button.
Despite the different names and shells, the soul of the Samsung Galaxy S 2010 was inside all of them. This fragmentation was annoying for software updates, but it meant that Samsung was everywhere. You couldn't walk into a phone store without seeing a Galaxy S variant on the shelf.
The legacy of the 2010 flagship
Samsung sold over 20 million units of the Galaxy S. That was a massive number for the time. It proved that there was a high-end market for Android that wasn't just occupied by tech enthusiasts or business people with BlackBerries. It was the first "cool" Android phone for the masses.
It also started the "Screen Wars." After the success of the Super AMOLED on this device, Samsung doubled down on display tech. They realized that if they could make the best screens in the world, people would buy their phones just to look at them. That bet paid off massively.
But more than that, the Samsung Galaxy S 2010 established the "S" branding. Today, the Galaxy S series is the only real rival to the iPhone in the global premium market. It all started with this thin, glossy, 4-inch plastic rectangle.
Acknowledge the flaws
It wasn't perfect. We shouldn't pretend it was. The software support was sluggish. Getting the update to Android 2.2 Froyo and then 2.3 Gingerbread took forever, depending on your carrier. The lack of a camera flash was a genuine "What were they thinking?" moment. The GPS was unreliable for months.
Yet, even with those flaws, the phone felt like a breakthrough. It had a "Lagfix" community that turned ordinary users into amateur developers. It pushed Google to make Android better. It forced Apple to keep innovating.
What you should do if you find one today
Maybe you have an old Samsung Galaxy S 2010 sitting in a "junk drawer" somewhere. Or maybe you're a collector looking to pick one up. Here is the reality of using one in the modern era.
Don't expect it to "work." The web has moved on. Modern websites are too heavy for a 1GHz single-core chip. Most apps won't even install because the Android version is so ancient. The battery has likely swollen or lost its capacity to hold a charge for more than ten minutes.
Use it as a dedicated media player. The Wolfson WM8994 DAC (Digital-to-Analog Converter) inside the Galaxy S was actually incredible. Audiophiles still praise it. If you can load it with local FLAC or MP3 files, it makes for a surprisingly great high-fidelity music player. Just plug in some decent wired headphones and enjoy.
Check the battery immediately. If you find an old one, open the back cover. If the battery looks even slightly puffy, get it out of your house. Lithium-ion batteries from that era are notorious for failing after a decade of sitting empty.
Appreciate the history. Turn it on. Look at that screen. Realize that in 2010, this was the absolute peak of mobile technology. It’s a reminder of how fast we’ve moved from 480p screens and 512MB of RAM to the pocket supercomputers we carry today.
The Samsung Galaxy S 2010 wasn't just a phone; it was the foundation of an empire. It was the moment Samsung stopped following and started leading. It proved that Android could be beautiful, fast, and desirable. It was the spark. Everything that came after—the notes, the folds, the ultras—owes its existence to this one device.

Quick Technical Checklist for Collectors
- Model Number: Look for GT-I9000 (the international version is the most prized by collectors).
- Screen Check: Check for "burn-in." AMOLED screens from this era often have ghost images of the status bar or the keyboard permanently etched into the display.
- Buttons: The physical home button and capacitive "menu" and "back" keys are prone to failing after years of use.
- Software: If it's running a custom ROM like CyanogenMod, it's a sign the previous owner was a true enthusiast.
The Samsung Galaxy S 2010 stands as a testament to a time when phones were still trying to find their identity. It took the best of what was available and shoved it into a package that changed the industry forever. It wasn't perfect, but it was exactly what the world needed to see that the iPhone wasn't the only game in town.
