Timing is everything in the tech world. Honestly, if you look back at 2017, Samsung was basically walking on eggshells. They had just come off the absolute disaster that was the Note 7—you know, the phone that was literally getting banned from airplanes because it kept catching fire. So, everyone was asking the same thing: When did Galaxy S8 come out, and more importantly, would it actually be safe?
The stakes couldn't have been higher. Samsung needed a win, not just a "good" phone, but a total home run to make people forget about the smoke and the recalls.
The Big Reveal: March 29, 2017
Samsung didn't go with their usual playbook for this one. Normally, they’d show off their new flagship at Mobile World Congress (MWC) in February. Not this time. They waited. They needed more time for safety checks and to make sure the "Infinity Display" was perfect.
The official unveiling happened on March 29, 2017, at a massive "Unpacked" event in New York City. I remember the vibe was weirdly tense. It wasn't just about the specs; it was about redemption.
When could you actually buy it?
The global rollout was pretty aggressive once they got moving.
- United States & Canada: April 21, 2017.
- South Korea: April 21, 2017.
- United Kingdom & Europe: April 28, 2017.
- Australia: April 28, 2017.
Some markets had to wait a bit longer, stretching into May for places like Malaysia or late May for the "Unlocked" versions in the US. By the time it hit the shelves, people were hungry for it.
What made the Galaxy S8 different?
If you held an S7 and then picked up an S8, the difference was night and day. It felt like the future. Basically, Samsung killed the physical home button. That was a huge deal back then! Everyone was used to that clicky button at the bottom.
Instead, we got this gorgeous, curved glass screen that took up almost the whole front of the phone. They called it the Infinity Display. It was an 18.5:9 aspect ratio, which made the phone taller but narrower. Super easy to hold with one hand, even if the screen was technically huge.
The Specs Under the Hood
Inside, it was a beast for its time. Depending on where you lived, you either got the Qualcomm Snapdragon 835 (USA/China) or Samsung’s own Exynos 8895 (Global). Both were built on a 10nm process—a first for the industry.

It also introduced Bixby. Kinda controversial, that one. People mostly hated the dedicated Bixby button because they kept pressing it by accident when they wanted to change the volume. But hey, Samsung was really trying to make their own AI happen.

Did it actually sell well?
Short answer: Yes. Long answer: It was a rollercoaster.
In the first month, Samsung moved about 5 million units. By August 2017, they had shipped over 20 million. In South Korea alone, pre-orders topped 1 million units in just a few days. People clearly trusted Samsung again.
But it wasn't all sunshine. Some early users complained about a "red tint" on the screen. Samsung had to rush out a software update to fix the white balance. Then there was the fingerprint scanner placement. It was right next to the camera lens. You'd try to unlock your phone and end up smudging your photos every single time. Sorta annoying, right?
Why the Galaxy S8 still matters today
You see the Galaxy S24 or the latest iPhones now? They all owe a debt to the S8. This was the phone that pushed the "bezel-less" trend into the mainstream. It forced Apple to finally move away from the big forehead and chin of the iPhone 7 and give us the iPhone X later that year.
It also kept the headphone jack. Man, those were the days.
If you're looking at a used one today, it's mostly a nostalgia piece. It stopped getting Android updates years ago (Android 9.0 Pie was the end of the road). But as a piece of tech history, it’s the phone that saved Samsung.

If you're thinking about picking up an S8 for a collection or as a backup "burner" phone, keep these things in mind:
- Check for Screen Burn-in: Those AMOLED screens are prone to "ghosting" or permanent image retention, especially on the navigation bar area.
- Battery Health: These phones are nearly 9 years old. The battery is likely shot. If you buy one, plan on a $50–$70 battery replacement.
- Security Risks: Since it hasn't had a security patch in ages, don't use it for your primary banking or sensitive work.
- The "DeX" Factor: The S8 was the first to support Samsung DeX. If you find a cheap DeX station, you can still turn this old phone into a basic desktop computer for web browsing.
The Galaxy S8 came out at a time when Samsung was down for the count, and it proved they could still innovate their way out of a corner.
