Improving on an already near-perfect phone was always going to be difficult for Samsung, but the Galaxy S9 Plus has fixed the select few problems we had with last year's Trusted Reviews Phone of the Year.

Feels great for a big phone; The OLED display is great and highly customisable; Numerous camera features on offer

Iterative upgrade; AR Emoji are just bad; Some lag with Samsung's software

Dual cameras come to Samsung's Galaxy S9 Plus, and they're reason enough to divert your gaze away from the regular Galaxy S9

Dual rear cameras for low-light photography; Unrivalled performance

Battery life isn't as good as last year's; Very expensive

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

The Galaxy S9+, like its predecessor, is an excellent smartphone with a fabulous screen and great performance. It's also more power-efficient and can be charged all the way up to 100 per cent in around 80 minutes.

Gorgeous design and screen; excellent camera; blazing-fast performance

Average battery life; 'Intelligent Scan' is glitchy; duplicate apps - and Bixby still needs work

The Samsung Galaxy S9+ should be the best phone of its generation, but a number of small grievances unite to diminish its appeal. It's technically capable, to be sure, but it's far from perfect.

Amazing screen; Super powerful; Fantastic camera for pros

Average battery life; Poor quality photos on auto; Bixby is still annoying

The phone itself has no lag and it performs well with inbound and outbound voice for calls. It took me a while to figure out how to avoid the Samsung-ness and use the native Android apps for almost everything I do on a phone but it has not let me down and the battery easily lasts all day for my...

The Samsung Galaxy S9+ is undoubtedly a good phone, if not a very good phone. While not a revolutionary upgrade, Samsung focused on minor improvements and many of these have led to a better smartphone than the Galaxy S8+. However at the same time, several areas of the Exynos model are disappointing.

Attractive, improved design with lots of killer features; Display is still excellent, despite no major upgrades; Strong camera performance

Disappointing performance and battery life from the Exynos model; Glass construction remains fragile; Galaxy S8 owners have no reason to upgrade

I have had this phone for about a month now and it has been absolutely awesome. The fingerprint scanner on the back seems to work really efficiently and I have not had any issues with software/app speed or user-friendliness.

Received the phone, Was tricky to turn on with sprint, Finally got it turned on, After about 6 weeks I got a black screen and the phone wouldn't power on or work in any way. Amazon / samsung sent a replacement, Got the replacement and its been a nightmare to turn on with sprint, In the end sprint...

I bought the Samsung Galaxy S9 six days ago and on the sixth day I noticed a hairline crack on the curved glass display. The glass may be tough on the flat surface but it is very fragile on the curved area. I would not recommend any phone with curved glass unless you keep a case on it at all times.

Poor quality
