2-minute Review [Positives]	Absolutely luscious design, continuing the design language that was introduced with the Galaxy S8 series (which is not a bad thing at all) - and it has some really sizzling color options in purple and blue, which really helps those supple curves stand out - the body colors look deep, rich and ever-changing thanks to the way the glossy glass catches the light - you will be hard pressed to find anything remotely as elegant, and beautiful in the Android market The S9's tall, narrow proportions fit your hand well - and it's significantly easier to handle than its larger cousin (S9+) The biggest design change is on the back, where the fingerprint reader moves below the camera module - this corrects the worst design mistake of both Galaxy S8 phones and the Note 8 Water resistant body The tall, 18:9, minimal bezel, 5.8-inch AMOLED screen is absolutely gorgeous and even brighter than last year's (15 percent brighter, in fact) - and the sexy dual-curved design adds to the charm Samsung software on top of Android adds some useful extras, extending the core functionality of Android - it is one of the better, more refined UIs in the Android world Whiplash-fast performance backed by the super powerful Samsung's Exynos 9810 (similar to the Snapdragon 845 in terms of performance) - performance is top-notch as expected under all use cases Terrific camera - the first to bring a mechanical dual-aperture lens from DSLRs to the much tinier mobile phone, a feature that's designed to let in more light, reduce image noise and generally make your photos a lot better The image quality in well lit situations is top-notch Low light performance often borders on astounding - with the amount of brightness & lack of noise you will find in the shots (thanks to the dual aperture lens) - although its not very consistent (some low light photos are oddly washed out) The super-slow motion video mode is pretty cool too, and when you frame the shot well, can give some incredible result The selfie camera is good too, and has a new Selfie Focus mode, which uses software (and not a second lens) to create a depth effect with the front-facing camera, similar to the Pixel 2, or the iPhone X On the whole the cameras on the Galaxy S9 compare well with the those on the other top camera phones - the Google Pixel 2, and the iPhone X - it's a toss up between these 3 - the Galaxy S9 can produce some truly exceptional shots especially in the dark, but perhaps the iPhone X and the Pixel 2 are just a bit more consistent all round, everything considered Dual-speaker system is excellent, and makes for loud, rich audio - and results in one of the best speaker experience of any smartphone, ever Call quality is fantastic too, with the AKG tuning really paying off Also has the good old-fashioned headphone jack! (that's missing in a lot of other flagships now) Good (though not exceptional) battery life - will definitely last the work day on a single charge Supports fast charging (although it's not the fastest around) Supports wireless charging DeX Pad support is another cool feature that enhances the Desktop Experience Samsung introduced on last year’s flagship Galaxy phones On the whole, while outside of the display, the S9 isn’t a class leader in any category, but it’s good enough in all of them that the whole package makes for a great flagship phone - it will compete with the Pixel 2/XL and the iPhone X for the title of the best smartphone - which one of these 3 you might choose will depend on what specific things you value	Absolutely luscious design, continuing the design language that was introduced with the Galaxy S8 series (which is not a bad thing at all) - and it has some really sizzling color options in purple and blue, which really helps those supple curves stand out - the body colors look deep, rich and ever-changing thanks to the way the glossy glass catches the light - you will be hard pressed to find anything remotely as elegant, and beautiful in the Android market The biggest design change is on the back, where the fingerprint reader moves below the camera module - this corrects the worst design mistake of both Galaxy S8 phones and the Note 8 Water resistant body The tall, 18:9, minimal bezel, 6.2-inch AMOLED screen is absolutely gorgeous and even brighter than last year's (15 percent brighter, in fact) - and the sexy dual-curved design adds to the charm Samsung software on top of Android adds some useful extras, extending the core functionality of Android - it is one of the better, more refined UIs in the Android world Whiplash-fast performance backed by the super powerful Samsung's Exynos 9810 (similar to the Snapdragon 845 in terms of performance) - performance is top-notch as expected under all use cases Terrific camera - the first to bring a mechanical dual-aperture lens from DSLRs to the much tinier mobile phone, a feature that's designed to let in more light, reduce image noise and generally make your photos a lot better The image quality in well lit situations is top-notch Low light performance often borders on astounding - with the amount of brightness & lack of noise you will find in the shots (thanks to the dual aperture lens) - although its not very consistent (some low light photos are oddly washed out) The Galaxy S9 Plus also one-ups the excellent Galaxy S9 with a second rear camera for taking portrait photos - they come out well with a good bokeh effect The super-slow motion video mode is pretty cool too, and when you frame the shot well, can give some incredible result The selfie camera is good too, and has a new Selfie Focus mode, which uses software (and not a second lens) to create a depth effect with the front-facing camera, similar to the Pixel 2, or the iPhone X On the whole the cameras on the Galaxy S9+/S9 compare well with the those on the other top camera phones - the Google Pixel 2, and the iPhone X - it's a toss up between these 3 - the Galaxy S9+ can produce some truly exceptional shots especially in the dark, but perhaps the iPhone X and the Pixel 2 are just a bit more consistent all round, everything considered Dual-speaker system is excellent, and makes for loud, rich audio - and results in one of the best speaker experience of any smartphone, ever Call quality is fantastic too, with the AKG tuning really paying off Also has the good old-fashioned headphone jack!

2-minute Review [Negatives]	Fragile glass front and back means you should buy a case day 1 The new face-unlock tool is not particularly secure (it might have been better for Samsung to build out a more refined version before rushing in to compete with the similar feature on the iPhone X) The 3D avatar software is again not that well executed - the AR Emojis track your expressions poorly and need far more customization options There’s also still no compelling use case for Bixby, Samsung's AI agent (though of course you have no compulsion to use it, and can instead keep using the Google Assistant) While the camera is great generally, it can sometime make low-light photos look blurry and lack detail - even though brightness levels is excellent and noise is minimal - so its sometimes a double edged sword The S9 also lacks the second rear lens of the step-up S9 Plus that's dedicated to creating those depth-of-field portrait shots that blur the background to make people and objects pop Battery life is good, but not exceptional - some of the competition is ahead here Everything considered, S8 owners can skip the upgrade - the S9 is excellent all-round, and incrementally better - but it's not a monumental change from the S8 Apart from the iPhone X and the Pixel 2/XL, the S9 will also face tough competition now from lower priced flagships like the OnePlus 5T, which are almost as good on most of the important counts	Fragile glass front and back means you should buy a case day 1 The new face-unlock tool is not particularly secure (it might have been better for Samsung to build out a more refined version before rushing in to compete with the similar feature on the iPhone X) The 3D avatar software is again not that well executed - the AR Emojis track your expressions poorly and need far more customization options There’s also still no compelling use case for Bixby, Samsung's AI agent (though of course you have no compulsion to use it, and can instead keep using the Google Assistant) While the camera is great generally, it can sometime make low-light photos look blurry and lack detail - even though brightness levels is excellent and noise is minimal - so its sometimes a double edged sword Battery life is good, but not exceptional - some of the competition is ahead here Among the two S9 variants themselves (standard, and plus), a lot of people might prefer the Galaxy S9, as it's a little easier to handle - the incremental improvements in the S9+ on the other hand (even bigger screen, more RAM, and a secondary rear camera) are arguably not that significant Everything considered, S8 owners can skip the upgrade - the S9+ is excellent all-round, and incrementally better - but it's not a monumental change from the S8 Apart from the iPhone X and the Pixel 2/XL, the S9+ will also face tough competition now from lower priced flagships like the OnePlus 5T, which are almost as good on most of the important counts The S9+ will also face direct competition from Samsung's Galaxy Note 8, which is pretty similar in many of the meaningful ways, but might come at a lower price
