2-minute Review [Positives]
  • Decent looks and build quality - with a a unibody polycarbonate design, and glossy finish on the back panel - quite similar to the M30 - the only major visual difference is that the triple camera setup gets a wider, rectangular module to house the LED flash and "48 megapixel" branding
  • The plastic body keeps the phone feeling relatively lightweight at 188 grams, which is mighty impressive for a phone packing a big 6000mAh battery
  • It also feels great to hold with a seamless curved panel that meets the display up front
  • Modern, Infinity-U front - bezels around the screen are slim, except for a slightly thick chin - you still get around 90 per cent screen-to-body ratio, which is great
  • Fingerprint sensor at the back is easy to reach
  • Gorgeous, 6.4-inch FHD+ (2340x1080) Super AMOLED Infinity-U display with excellent viewing angles, and brightness levels - easily one of the best displays in the price bracket
  • It also comes with "Widevine L1" certification, which helps stream content in crisp HD resolution
  • Blacks are deep on the AMOLED display, which looks good with Night mode enabled
  • Samsung's OneUI is today one of the more clean, refined Android UIs that's especially well optimized for large displays like this
  • One UI also brings in other useful stuff, like a System-wide Night mode (which turns the background completely black, and looks great on the M30s' AMOLED display), and Always On Display option
  • Good, strong performance with the Exynos 9611 at the core (similar to Snapdragon 665) - everyday performance to high-end gaming - everything is handled smoothly
  • Good rear camera setup - 48MP main sensor + 8MP wide-angle lens + 5MP depth sensor
  • With the primary lens, you get bright and attractive photos in daylight conditions with vibrant colours and good contrast - dynamic range is also wide and noise is controlled
  • Switching to the wide-angle lens will offer a new perspective, letting you click a wider area at close range to the subject (it is best used in daylight, however, as wide-angle captures look grainy and noise indoors or in low light)
  • The dedicated Night mode can be used with the main camera - it comes in handy in low-light conditions, extending the shutter time to allow more light into the frame - making for some decent low-light photos
  • Live Focus does a decent job at separating the subject from the background, and giving good bokeh shots
  • The 16MP selfie camera too does a decent job when it comes to capturing selfies outdoors under bright light (though it starts to struggle indoors and in low light, offering softer selfies with a lot of grain)
  • Overall, the cameras on the M30s are good for the price bracket, even though they are not the best (that title is shared by Xiaomi and Realme phones)
  • Monster 6000mAh battery delivers an incredible 2-3 days of usage easily, making for one of the largest battery life smartphones currently available
  • Supports 15W fast charging
  • With the M-series performing well for Samsung, M30s is well-set to add to that success, delivering a good all-round package with one key differentiator - an incredible battery life - if that is one of your primary concerns in a phone, then the M30s is a no-brainer (if on the other hand you want the best camera or best performance for your buck, you can look at Xiaomi or Realme phones in this price bracket)
  • 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
2-minute Review [Negatives]
  • The power button and volumes are quite flush with the frame which means they lack that tactile, clicky feel
  • Lacks the premium finish of some of its competitors
  • Focusing is slow at times
  • Overall low light camera performance still feels lacking
  • 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
