It's true what they say - you don't fix what's not broken. And that's what Samsung did for the Galaxy S9 - it didn't change what was already great, it just tweaked specs wherever possible. And it has worked out just fine for them.

Premium water-tight design; Class-leading AMOLED screen; Among the fastest Android phones (in benchmarks; Great audio skills and stereo speakers; Variable aperture camera; 960fps slow-mo; automatic motion detection; Class-leading still and video quality; Excellent retail bundle

We prefer the Samsung Galaxy S9 over its larger sibling S9+. It is not as bulky and the dual-camera is not worth the additional price. The Korean manufacturer once again delivers a really great smartphone, but it is more of a facelift of last year's Galaxy S8 and there are still some bugs, and some...

Samsung released the Galaxy S9 and the S9+ in March 2018. The smartphone duo set the bar for all the competition this year. The S9 doesn't bring a radically fresh design, but under the hood and in terms of software features, things are different.

Performance; Camera; Display; Bixby

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

The Samsung Galaxy S9 forces us to question upgrades for their own sake. On the one hand, there's our desire as consumers to have the very latest tech gadget, even if we don't even use the phone we have now to its full extent.

Galaxy S8's excellent design gets even better; Screen; performance & battery all solid; Camera capable of impressive low-light performance; Price is competitive

Intelligent Scan trades security for convenience; Super Slow-mo is 720p only and needs bright lighting; Bixby still feels gimmicky

Just minutes after getting my hands on Samsung's latest flagship S Series smartphone, one fact was abundantly clear - if you weren't fond of the Galaxy S8 and S8+, then you're going to have similar feelings about the S9 and S9+.

Super Slow-mo mode is great (when it works; One of the best Android cameras out there; Build quality is superb

Looks the same as the S8/S8; Glossy body isn't for everyone; AR Emoji are lacklustre

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

Samsung has just announced its Galaxy S9 and Galaxy S9+ flagship smartphones at Mobile World Congress in Barcelona. Once again, many of the rumors leading to the launch were spot on: the Galaxy S9 is everything the industry expected it to be, and a little bit more.

Excellent Performance; Excellent Display; Insane Low-Light Camera and Slow-Mo

Nothing Obvious

Samsung's Galaxy S9 and Galaxy S9 Plus were announced in late February and went on sale in the middle of March. Since that time, ZDNet's Matthew Miller reviewed the bigger Galaxy S9 Plus, proclaiming the device is "Android perfection achieved."

Fast; reliable performance; It has a headphone jack; Reliable camera

Battery life; Super Slo-Mo is good; but not great

Samsung has done some pretty impressive upgrades on the Galaxy S9. It's got a slightly more compact in an almost identical design, a more practical placement of the fingerprint scanner and an inclusion of stereo speakers are all nice.

Impressive performance; Very nice display; Great camera performance; Loud; stereo speakers; Fast wireless charging; Water resistance

Battery life did not improved; Super expensive

I had the Galaxy S8 and the I-Phone 8 Plus and this phone is excellent for the most part. The battery life is good given I keep the display set on QHD. Why keep it on HD or FHD if the screen resolution is QHD I find that a charge does last me the day with adjustments to increase battery life.

QHD+ Display; Good Battery Life; on Standby; Keyboard input is fast; Dolby Atmos is Great sounding; AKG Earphones; Fingerprint Sensor Good; Camera is Great; Photos come out well

Speakerphone a bit low; Some Ringers are low in volume; Battery drains fast if screen stays on
