Samsung's flagship smartphone was announced at Mobile World Congress, back in February 2018. Both the S9 and the S9 Plus were announced on the same day, with the S9 Plus being both bigger and having some additional features, particularly to the camera.

A very capable flagship with lots to love, but the back-step in battery performance is disappointing. The camera is easily the best on the market by a country mile, as is the display, while CPU performance is also great - however, you do pay quite a lot for all this

Excellent display; Top-tier processor performance; Superb best-in-class camera; Attractive design; Waterproofing

Battery life has taken a hit; Expensive; UI foibles

It's not revolutionary, but the Samsung Galaxy S9+ sets the bar for smartphones in 2018, with the best hardware features you can get.

Gorgeous screen; Beautiful body; Spectacular network performance; Dual main cameras with excellent low-light capture; Loud audio

Camera software oversharpens images; AR Emoji and Bixby disappoint

It might be a chunk more expensive, but the Galaxy S9 Plus is the more interesting and impressive of the two. Find out if it's the right phone for you in our full review.

The Galaxy S9+ is still a gorgeous and almost flawless phone, offering premium specs and features in a sleek and well-made design. There is the issue of it being very similar to its predecessor but we're glad Samsung hasn't dropped the headphone jack and introduced a notch - if it 'aint broke. Of course, the brilliant Galaxy S10 Plus is here to replace it now which will be tempting for its new design and features, but it's expensive so the S9 Plus remains an excellent option at a much lower price. Below is our original Galaxy S9 Plus review.

Samsung's most robust Galaxy S9 of 2018 is still a good buy, but not until after the Galaxy S10 starts selling.

The Galaxy S9 Plus one-ups the excellent Galaxy S9 with a second rear camera for taking portrait photos.

Battery life fell short of last year's model in our early tests, and the Galaxy S9 Plus suffers from the same underbaked extras as the smaller Galaxy S9; The dual-aperture camera tends to overexpose low-light photos in auto mode.

After the launch of Apple's 10 th anniversary iPhone X , all eyes were on Samsung to check whether the Korean smartphone giant could deliver a smartphone that could one-up Apple's new Face ID technology along with its edge-to-edge display, which also introduced the annoying notch.

Samsung's Galaxy S9 Plus is the more robust Galaxy S9, and the one for power users to get.

Times have changed since Samsung revealed the Galaxy S9, Galaxy S9 Plus and even the Galaxy Note 9 last August. The Galaxy S10 ($330 at Amazon) looms large on the horizon, launching on Feb. 20 in San Francisco -- this year we expect three new models, including a cheaper Galaxy S10 E, or S10 Lite. Normally the Galaxy S10 Plus would steal the show, but we're also expecting Samsung to tease or even fully unleash its first 5G Galaxy S10 model, and it first foldable phone, which the company briefly showed off this past November.
