Update: New Samsung Galaxy S9 Plus storage sizes are available with 128GB and 256GB options in the US – for a higher price. Here's our updated review of the Android phone with a large screen.

Impressive low-light camera; Better-placed fingerprint sensor; Loud stereo speakers

Not all that different to S8 Plus; AR Emoji mode is overrated; Pricey for 0.4 in of extra screen

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

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

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.

With the Galaxy S9 Plus, Samsung has managed to create a great smartphone again that received many sensible improvements but no real innovations. The main camera's two aperture levels are a great thing to have and work well in everyday life. Samsung has also optimized the image quality further.

no dual-VoLTE; worse battery runtimes than predecessor; long charging time; SoC throttling under constant load; no warranty for damage caused by liquids

Though it'd be easy to talk down Samsung's bold claim that the new Galaxy S9 and S9+ "reimagine" the camera, it's hard to argue that putting that particular aspect of their latest flagship smartphone front-and-center isn't a savvy move by the South Korean tech giant.

Great camera for both stills and video; Infinity Display still great

Battery life; Bixby still kinda mediocre; Your mileage may vary on AR emojis

The Galaxy S9+ is an iterative update, but that doesn't stop it from grabbing the top spot, at least as far as Android phones are considered.

Dual Aperture camera; Astoundingly bright display; Superior build quality

AR Emoji; Cluttered UI

It has been the uncrowned king of the Android smartphone kingdom – no phone has been more compared with Android's bête noire, the iPhone, for more than half a decade now. But recent times have seen Samsung's iconic Galaxy S series face an increasing number of challenges not just from Cupertino but...

Great display and sound; Very good cameras; Excellent overall performance

Samsung Experience UI remains cluttered; Camera not "as great" as hyped; On the expensive side

The S9+ is the new bully on the block: it's big, strong, and fast. But 2018 just started, so the Korean company's rivals will certainly not just let it rule the market. The Huawei P20's release is just around the corner and the Xperia XZ2 already has a lot up its sleeve to try and oust the Galaxy...

Best display in the world; Excellent performance; Dual camera; Variable aperture in main camera; Quick recharge; 6GB of RAM

Battery life; Still runs on Android 8.0; Iris Scanner and Face Unlock
