2-minute Review [Positives]
  • Incredible overall fit and finish
  • Water-resistant (IP 68 certification), and with Gorilla Glass 5 protection on both front and rear
  • Relatively comfortable to hold for a display this large in size
  • 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 on-screen navigation works well and buttons can finally be re-mapped - the home button has nice haptic feedback
  • 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
  • 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
  • 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
  • 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
  • The new 18.5:9 aspect ratio for the display works great for portrait gaming, browsing and multi-tasking
  • 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 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
  • Very good battery life, a little better than the already good battery life of the Galaxy S7
  • 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 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
  • Fresh, bright and vibrant design, with a gleaming, reflective rear panel - the design here is very similar to that of the Note 9 Pro’s with the back is now made of polycarbonate
  • The distinctive camera bump design plays into the theme of symmetry - this is a beautiful design touch that sets the Redmi Note 9 series apart and makes this phone and its siblings recognisable
  • The front of the phone looks modern and defies expectations for its price category - the hole-punch is now on the left unlike the other 2 Note phones that have it in the center
  • Fingerprint sensor is moved to the back, and it is swift at unlocking the phone
  • Xiaomi's trademark infrared emitter is on the top and can be used to control several home appliances
  • Crisp, vivid and bright 6.53-inch IPS display with a tall aspect ratio - the panel delivers punchy and vibrant colours and the large screen work nicely for consuming videos and games
  • The display also gets sufficiently bright for outdoors use
  • MIUI is one of the more refined and smooth Android skins around, and has a lot of customisation/theming options - there are ample features for power users - from gestures to the ability to switch around button layouts as well as a robust home screen customisation experience, you can make the phone your own
  • Good performance for the price powered by the respectable new MediaTek G85 SOC - the day-to-day tasks on the Redmi Note 9 feel light and effortless and it can run heavy 3D games like PUBG at low or medium settings
  • Decent quad cameras for the price - a 48MP primary shooter, an 8MP ultra-wide-angle lens, a 5MP macro camera and a 2MP depth sensor
  • In daylight, the primary camera takes reasonably good shots - Xiaomi has opted for a very natural-looking colour science, the colour temperature and white balance are spot-on which is very good to see, and the dynamic range isn't too bad either (though, there is a certain softness to images, which can be fixed with a software update)
  • The ultra-wide-angle mode works well to capture a wide frame without much effort, and the quality is decent
  • Xiaomi has done a particularly good job at optimising the portrait mode, and the phone does a fantastic job at edge-detection, creating a natural-looking blur
  • The macro camera delivers good quality shots than from most other 2MP macro cameras because of the autofocus
  • The 13MP front camera is fairly good in the daytime as well as at night - details are crisp, and portrait shots have nicely blurred backgrounds, which can be pre-adjusted
  • Very good battery life with the 5020 mAh battery - with ordinary use, the Redmi Note 9 easily lasts through a full day and nearly half of the second day before needing a recharge
  • Decent fast charging with the 18W fast charger in the box, takes nearly 2 hours to fill the phone (though this isn't the fastest charging phone and the Realme 6i's 30W charging is much better)
2-minute Review [Negatives]
  • 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 all-glass body is quite slippery, if you don't use a case
  • 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
  • At 8.9mm thick and 199g in weight, the Redmi Note 9 is a bit bulky and unwieldy
  • It continues to pack a lot of bloat though - you get many pre-installed applications with wide-ranging requirements for user permissions
  • The gaming performance is a downgrade from other Note 9 series phones, you'd be better off with phones like Redmi Note 9 Pro or Redmi 6i if you want a phone for heavy gaming
  • Low light photography is average, images are grainy with digital artefacts and splotches creating a nearly unusable shot
  • Overall, this is not the best camera setup at this price and this time Realme has done a better job which with its Realme 6i which offer better cameras at this price
  • The Realme 6i out-specs the Redmi Note 9 at every corner, be it high refresh-rate 90Hz display panel, or the supported faster 30W charging as well as the much better MediaTek G90T SOC, at just marginally higher price - Realme 6i is an all-round better deal
