2-minute Review [Positives]
  • The best looking OnePlus phone to date - has a polished refined design, with a glass rear panel, and three distinct (and beautiful) color options (plus the Marvel Avengers edition)
  • Excellent build quality
  • The phone is comfortable to hold, thanks to the curved glass rear
  • Face unlock works great in most conditions, and unlocks the phone in a fraction of a second (except in low light or under very bright sunlight)
  • There is also of course the fingerprint sensor at the back, if you wish to use that instead, and it works great too
  • OnePlus's excellent alert slider is there too (it has now moved to the right side of the phone) - and is now more simplified toggling between 3 simple states - ring, vibrate and silent, with a pop-up that tells you instantly which mode you are switching to every time
  • Excellent display - catches on to the modern 'notch' trend, with a tall screen ratio - the AMOLED screen is vivid, with punchy colours and great viewing angles - videos looks great, and you can also set your own custom colour temperature if you prefer
  • OxygenOS continues to be a huge differentiator for OnePlus - it strikes a great balance between keeping the base UI identical to stock Android but still adding a number of useful additions - like shortcuts, a dark theme, a scrolling screenshot capture tool, and controls for giving the on-screen buttons additional functions, night and reading modes, a choice of system fonts, and configurable colours for the notification LED - all in all, its a great software experience, that ticks the right boxes
  • Another interesting add-on is an optional gesture scheme that lets you get rid of the Android navigation buttons altogether, and gives you a full gesture based navigation scheme like the iPhone X - thus giving you even more screen space to play with - the gestures do take some time to get a hang of, but once you do, they will become second nature
  • There's also a Gaming Mode that not only suppresses non-essential notifications, but can also limit background apps' Internet usage, which can make a difference in online games - you can even route calls directly to the loudspeaker so you don't have to stop playing
  • Top-notch, breathtaking performance, backed by the latest flagship processor from Snapdragon, the Snapdragon 845 - the SoC has eight Kryo 385 cores, integrated Adreno 630 graphics, improved security and image processing subsystems, a faster LTE modem, and even hardware dedicated to AI processing - all of this means the performance is top-bracket, matching (or beating) the Galaxy S9/Plus in benchmark scores
  • Good set of dual rear cameras, significantly improved from the OnePlus 5T - especially in terms of portrait mode photos, low light performance, and video recording (including a new super-slow motion mode)
  • The rear cameras now also come with OIS
  • Decent (though not great) front camera, pretty similar to the OnePlus 5T - a software bokeh mode for the front camera is also there
  • Decent loudspeaker (pretty loud) - although it tends to get blocked when you hold the phone in landscape mode
  • Good (but not exceptional) battery life - will comfortably last the day with moderate to heavy use
  • Fast charging support, still one of the best in the business - the Dash Charger takes the phone up from zero to just over 50 percent in half an hour, and gives you a full charge in around an hour and a half
  • On the whole, the OnePlus 6 is good-looking, well crafted, extremely powerful - it is also a solid upgrade to the OnePlus 5T in almost all the departments such as display, performance, design and camera - and ultimately the OnePlus 6’s bang for buck is still about the best you can get in the smartphone world
  • 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! (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
2-minute Review [Negatives]
  • Will also tend to pick up smudges very quickly
  • It's not the easiest to reach all corners of the newly enlarged screen - people who prefer more compact phones might have preferred a smaller-screen option for themselves
  • While OnePlus does claim that the phone has water-resistance, it's not IP rating certified, which likely means that the protection is quite basic
  • A little slippery because of the glass
  • At 177g, the phone is a bit on the the heavier side too
  • The rear and front cameras are good, but not really up to the high benchmarks set by the likes of the iPhone X, the Galaxy S9, or the Pixel 2 - this continues to be the only one significant area, where you will be making a compromise over the best flagship smartphones, when you buy a OnePlus device (of course admittedly for a much lower price)
  • 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
