Samsung's improvements to its latest flagship work as promised, but don't feel like features that you'd miss by not upgrading. Still, thanks to blazing performance, solid cameras and long battery life, the Galaxy S9+ continues to uphold the S series' reputation for excellence.

Dual Aperture effective in low light; Excellent cameras overall; Speedy performance; Long-lasting battery; Good cameras especially in low light; Superior performance; Gorgeous design

Not a major improvement over last generation; No major change since last generation; Lacks the Plus' dual cameras

Let's face it: the changes you're going to see in smartphones every year are pretty incremental. With some significant exceptions (I'm looking at you, user interface of the iPhone X ), today's phones aren't all that much different than the phones of three years ago. Faster, yes, More memory, sure.

Solid performance; classic Samsung design; Dex dock allows use as desktop computer

Iris scan feature needs work; Bixby virtual assistant remains a work in progress; AR Emoji a half-baked gimmick

The Galaxy S8 was the best phone of 2017. The Galaxy S9 is a little better. The Galaxy S9+ is even better. It's up to you whether the size and cost are worth the power: For us, they are.

Feels great in one hand; Excellent low-light camera performance; Better sound and network support than the Galaxy S8

Not a radical upgrade from the Galaxy S8; Larger S9+ model has better cameras, more RAM, and stronger Wi-Fi performance

The time has come: Samsung has unveiled the Galaxy S9 and the S9+, the smartphone duo which will set the bar for all the competition this year. The S9 doesn't bring with it a radically fresh design, but under the hood and in the software features, things are different.

Unoriginal design; Slow unlocking; Battery life; Bixby wake-up

In some ways, the Samsung Galaxy S9 is a serious step up from last year's flagship phone. In particular, its new 12-megapixel f/1.5 rear camera performs far better in low light than its predecessor. Its new Exynos 9810 processor also promises significantly faster performance.

Far from playing it safe, Samsung has further refined an already excellent design language, adding in new features and improving what needed improving. Brand-new Dolby Atmos-grade speakers are among the best new enhancements that will make daily use of the phone better than ever, and the slew of...

Gorgeous; IP68 water and dust resistant build; Industry-leading display; Incredible Dolby Atmos speakers; 3.5mm audio jack; PMA and WPC wireless charging support; Edge panels are ultra useful; Ultra-fast performance; Samsung Pay is still the best mobile payments solution; Great new biometric...

Only supports QuickCharge 2.0; Camera noise processing is still too heavy; Front-facing camera should be better; New camera interface is terrible; Battery life should be better; Having fewer features on the smaller Galaxy S9 camera is lame

When Samsung Galaxy S9 rumours started circulating, all of them share one common point: it's more of the same. Often times, it does sound like it's a bad thing.

The Samsung Galaxy S9 is now on the shelves, a phone that promises to be one of the best of 2018 - but at first glance, might not seem to be that much of an upgrade.

Swift biometric security; Awesome low-light performance; The most powerful Android phone out

Design is identical to S8; Some camera snaps lack vibrancy; Expensive

Samsung has been the king of the Android phone market for some time now. But is this set to change in 2018 with the release of its latest flagship? Does the S9 have enough to beat the , and ?

Fantastic display; Feels great; Much improved speakers

Average battery life; Dual-sensor only on Plus model; Some lag with Samsung's software

While it's not perfect, the Galaxy S9 is a fantastic device. It's got a brilliant display, great camera, brilliant performance all-round, and in a body that's easily one of the most elegant ever released. Its stereo sound makes such a difference to media consumption too.

Brilliant display; Stereo sound is surprisingly powerful; Curved glass and metal is very attractive; Comfortable to use; Super speedy and fluid performance

Battery isn't great; Camera over-exposes highlights regularly; AR Emoji and Bixby need a lot of improving; Expensive
