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
  • With its bold, exquisite, elongated shape, and borderless "infinity" display, the Galaxy S8 is one gorgeous piece of technology - arguably the best designed Android phone to date
  • Incredible overall fit and finish
  • Water-resistant (IP 68 certification), and with Gorilla Glass 5 protection on both front and rear
  • Apart from fingerprint recognition, you also have iris or facial recognition options for unlocking the device - iris is blazing fast, but requires some careful alignment - facial recognition works pretty well, but does require good lighting
  • The new 18.5:9 aspect ratio for the display works great for portrait gaming, browsing and multi-tasking
  • The new on-screen navigation works well and buttons can finally be re-mapped - the home button has nice haptic feedback
  • The exceptionally bright Infinity display is gorgeous, and a chart-topper in terms of sunlight visibility - and colors are even punchier than before
  • Samsung's TouchWiz software is now more polished than ever, and gives a thoughtfully conceived software experience
  • Samsung's AI Engine Bixby is a decent add-on too, although a lot of the functionality, including voice activation will come in later
  • The Exynos chipset powering the phone delivers a chart-topping performance in both CPU and GPU benchmarks - the Mali-G71 MP20 GPU is impressive too - overall, the performance is class leading, and brimming with horsepower
  • The camera is state-of-the-art and pretty much the same as the already great camera on the S7, with one notable improvement - low light photography - the new Multi-Frame Image Processing delivers noticeably cleaner and sharper low light photos - overall now, this camera is right up there with the best in the business - the iPhone 7 and the Google Pixel
  • The front camera is very good too, and a major upgrade from the S7 in terms of image quality - Samsung has also included a big collection of filters, stickers and dynamic facial effects to raise your selfie game
  • Good audio quality
  • The S8+ is is really versatile when it comes to connectivity too with things like Gigabit LTE support, bluetooth audio streaming to two devices simultaneously, and presence of DisplayPort video output over Type-C
  • You can also use the phone as a mobile workstation with the DeX desktop dock - creating an Android "desktop" experience - which could be pretty handy
  • Very good battery life, a little better than the already good battery life of the Galaxy S7
2-minute Review [Negatives]
  • A little slippery because of the glass
  • 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
  • At 177g, the phone is a bit on the the heavier side too
  • 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
  • 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)
  • The all-glass body is quite slippery, if you don't use a case
  • The new fingerprint reader position at the back will certainly raise more than a few eyebrows - it's too high up and right next to the camera - which is not the most convenient placement
  • The S8+ is also generally quite tall for one handed use - reaching the notification area, for instance, can be tricky - similarly, the on-screen navigation buttons are placed pretty low relative to the overall height of the S8+ and can also be hard to reach
  • While the 18.5:9 aspect ratio is futuristic, and certainly comes in handy while browsing, and gaming, but most video/image content is still not made for such a wide screen, so will usually be wasteful of the extra space
