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

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.

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'm kind of torn about the Galaxy S9+. It improves on the best Android phone of last year in several key ways, including in performance, low-light photography and slow-motion video recording.

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

Plus-sized phones often find themselves stuck in a plus-sized niche – but Samsung's Galaxy S9 Plus is different to most. This time around, it's ready to steal the spotlight from the regular S9.

Dual rear cameras for low-light photography; Unrivalled performance

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

Every year the Samsung Galaxy flagship is the most anticipated Android device. And Samsung does enough every year not to disappoint hardcore fans and to show direction to the rest of the industry. This year it has launched the Samsung Galaxy S9 and S9+.

Loving this phone so far. Upgraded from the Galaxy S6 edge and I'm really enjoying the quality of the screen, camera, and overall layout of this phone. I love the side panel for frequently used apps instead of having them covering the home screen.

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
