2-minute Review [Positives]
  • The M40 is the first mid-range phone from Samsung with an Infinity O display (till now it was only available with the Galaxy S10 series) - the front camera is under the display in the hole punch on the top left of the screen which helps achieve a near bezel-less display - the phone is definitely a head-turner
  • The body is polycarbonate (though it feels glass-like) has a very premium look and a slight gradient effect
  • Polycarbonate body also means that the phone is pretty light-weight
  • The middle camera sensor at the back has a silver ring around it, which stands out very subtly
  • Large, bright display - you get good viewing angles and sharpness
  • Samsung's new One UI is one of the most clean, and refined implementations of Android at present, and is quite smooth in day-to-day use - so on the software front, Samsung scores a big point
  • Solid performance with the powerful Snapdragon 675 processor (same as Xiaomi Redmi Note 7 Pro) - everything from day-to-day performance, to games, is smooth
  • Decent set of triple rear cameras (standard + ultra-wide + depth)
  • Image quality is reasonably good in well-lit environments
  • Portrait shots came out really well with the subject well defined and the background blurred
  • The 16MP front camera also does a decent job of taking pictures in daylight - the photos look sharp with enough details and colours are close to natural
  • Overall, the camera performance isn’t the strongest in its price range, but fairly good overall
  • A stand out feature is the On Screen sound technology where the display doubles up as a speaker (it works well)
  • Good battery life with a 3500mAh battery - you can expect it to comfortably last the day - though of course it's not quite as brilliant as the 5000mAH batteries on the Galaxy M30 and M20
  • Samsung continues it's smart comeback into the mid-range with another good addition to the M-series - the M40 is a good alternative to consider in this price bracket, for people who want to prioritise a stylish cutting-edge design, and a 'notch-less' screen
  • Beautiful, 'shimmering' rear (plastic) panel, and a modern, notch-less 6.5-inch OLED screen - easily one of the best looking phones in this price bracket
  • The notch-less display spans almost edge to edge, with a pop-up selfie camera mechanism
  • Fairly fast in-display fingerprint reader
  • Very good 6.5-inch OLED screen - colors are lively, with deep blacks
  • The lack of a notch really helps make the screen appear immersive, and consuming content on the screen is a pleasure
  • ColorOS UI is now much more streamlined than before - there’s also now an app drawer, and a useful shortcut menu accessed by swiping from the sides
  • The gesture navigation is nice and intuitive too
  • Very good performance backed by the powerful Snapdragon 710 chipset - everything from daily use to high-end games is smooth
  • GPU performance is an especially strong point of the Snapdragon 710, so if you are into gaming, the phone tends to comfortably outperform rivals
  • Excellent set of dual rear cameras (48MP+5MP) and front camera (16MP)
  • Very good overall image quality in daylight, and fairly good quality in low-light as well
  • Night mode is pretty effective too
  • Very good portraits
  • Pretty great selfies too, from the 16MP front camera
  • Realme’s EIS does a solid job of stabilization during videos at up to 1080p/30fps
  • Support for 4K video recording (without EIS though)
  • Overall, the Realme X is arguably the best camera setup of this price bracket now, even beating the excellent cameras on the Redmi Note 7 Pro and the Realme 3 Pro - and is in fact comparable to cameras in phones at twice the price
  • Good battery life with a 3750 mAh cell - you will comfortably get a day of use, even with heavy usage
  • The class-leading VOOC fast-charging nicely complements the long battery life - it fills a completely depleted battery in 1:18h and it's at the 50% mark 30 minutes into it - which are some excellent numbers
  • The Realme X looks like an incredible value package, no matter how you look at it, and will inevitably disrupt its price bracket in a big way - what you get is top-end specs, a 'full screen' AMOLED display with a pop-up selfie camera, very good performance, an excellent set of cameras, and super fast charging - you can't ask for more
2-minute Review [Negatives]
  • Both fingerprint unlock (the fingerprint sensor is on the back), and the face unlock, while decent, aren't the fastest
  • It's not AMOLED though, so purely quality wise, the display is not quite as vibrant and punchy as the Galaxy M30
  • Tends to warm up a little bit, during heavy gaming
  • Low light performance from both the rear and front cameras is pretty average though
  • There is no 3.5-mm headset jack, which could be an issue for some users (USB-C headphones are bundled though)
  • There is some pretty good competition though, make no mistake - there is Samsung's own Galaxy M30 (cheaper, better display, better battery, headphone jack, although it has a slightly inferior processor, and not the cutting edge 'punch-hole' design), the Poco F1 (flagship Snapdragon 845, headphone jack, though it doesn't have a very modern design), and the Redmi Note 7 Pro (cheaper, better battery, headphone jack, though MIUI is not as simple/refined as the One UI) - all of which are excellent value themselves, so what you chose will depend on what you value
  • ColorOS still has some bloatware though, and is not quite as clean/simple as stock Android
