6) They come with a new friend called Bixby
Apple has Siri, Microsoft has Cortana, Amazon has Alexa, Google has, um, Google. And now Samsung has Bixby.
Yes, the S8 and S8+ come with a built-in digital assistant to answer every question and generally act as a digital lacky. Samsung clearly thinks this is a big deal, because it’s even given it a dedicated hardware button.
What’s more, it’s designed to be a mobile-first thing, so that rather than just recognising your voice it also knows what you’re looking at on screen or through the camera. No, that’s not in any way spooky and ripe for hacking.
Samsung’s Touchwiz skin returns here on top of Android 7.0 Nougat, together with a few tweaks to the way that, for instance, multi-window viewing works.
7) They'll take amazing selfies
In many ways the S8 is a vastly different phone to the S7, but strangely the camera’s not been changed that much at all. Or maybe it’s not that strange - the S7’s camera is easily one of the best out there, and Samsung didn’t need to make huge changes to it.
So, unlike on the LG G6, the Huawei P10 and the iPhone 7 Plus, there’s no dual-camera setup here. Instead, you get a 12MP, f1.7 sensor with optical image stabilisation, just as we had on the S7.
What is new, though, is the three-shot burst image processing. The S8 and S8+ will actually take three photos every time you press the shutter button, then use two of them to reduce blur and noise in your shots. It’s similar to what Huawei, for one, does with its second camera lens, but without some of the other benefits such as increased depth of field or zoom.
The front camera has had a spec bump, however - it’s now an 8MP, f1.7 effort, up from 5MP on the S7, and it comes with built-in stickers and filters straight outta Snapchat, plus what should be impressive autofocusing abilities to make sure (or you and your mates) are nicely in focus.
8) They'll have plenty of power
We’d expected the Galaxy S8 and S8+ to launch with the new Qualcomm Snapdragon 835 processor, but instead, in the UK at least, there’s an octa-core Exynos CPU inside them. It's well-clocked, though, with 4 cores running at 2.3GHz and 4 at 1.7GHz, so we see no reason to suppose it won't handle everything you throw at it.
You also get 4GB of RAM, which isn’t the most out there - the Huawei P10 Plus has 6GB and the Asus Zenfone AR comes with 8GB, for starters - but which should be plenty. There’s only one size in terms of storage: 64GB, with the ability to add up to 256GB more via microSD.
Battery life might be an issue - not in the way that the Note 7’s was, hopefully, but in that the S8 has only a 3000mAh cell. That’s less than plenty of rivals, although it does at least have fast charging. The S8+ gets a bigger 3500mAh battery, but then again it also has a bigger screen to power. It's also worth noting that the Exynos chip's 10nm process should aid battery conservation.
9) They'll turn into PCs
Loads of phones have tried to do the whole ‘I’m a phone! Now I’m a PC!’ thing before, but the Samsung Galaxy S8 and S8+ might actually nail it.
It’s all thanks to the Dex Station - a little dock that you plonk your phone into then hook up to a TV. It has two USB ports, Ethernet and HDMI, and once connected to a screen it’ll give you a Windows-style desktop with app launcher, taskbar and so on. Sweet.
There's also Bluetooth - so you can hook up a mouse and keyboard - and that dock itself acts as a fast-charging port for the phone.
It's all built around Android, obviously, but partnerships with Microsoft and Adobe should give you access to Office and the like.
10) They have headphone sockets
Have we missed anything? Probably. Oh yeah - the S8 is waterproof (to IP68), charges via USB-C - and has built-in wireless charging - and still has a headphone socket. IN YOUR FACE iPHONE 7!
11) They'll cost a fortune
All sounds great, right - but there’s a catch, because the S8 and S8+ will be pretty expensive.
The Galaxy S8 will set you back £689 and the Galaxy S8+ will cost £779. That’s considerably more than the S7 - which was £570, or £640 for the Edge version. Blame the price hike on all that extra glass on the front, plus Brexit. Thanks, Theresa May.
Still, it’s not vastly more than other flagship phones of this size - after all, the Huawei P10 Plus costs £680 and the iPhone 7 Plus £720 for the 32GB model, rising to £819 for the 128GB version. And remember the S8 comes with 64GB as standard.
They're available to pre-order RIGHT NOW and orders placed before 19 April will start being delivered from 20 April. The phones will be on general sale from 28 April.
