2-minute Review [Positives]
  • Decent looks and build quality - very similar to the Samsung Galaxy M31, with a a unibody polycarbonate design, and glossy finish on the back panel - the only major difference is the camera module which houses a triple rear camera
  • The plastic body keeps the phone feeling relatively lightweight at 188 grams, which is mighty impressive for a phone packing a big 6000 mAh 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 and work very well
  • Gorgeous, 6.4-inch FHD+ Super AMOLED 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 optimised for large displays like this
  • One UI also brings in other useful stuff, like a System-wide Dark mode (which turns the background completely black, and looks great on the M21's AMOLED display), and Always On Display option
  • Decent performance with the Exynos 9611 at the core (similar to Snapdragon 665) - the device is fairly quick to load up apps - multitasking is a breeze
  • Decent triple rear camera setup - a 48MP primary snapper, an 8MP ultra-wide lens and a 5MP depth sensor
  • In broad daylight, you'll get consistent, crispy shots with decent dynamic range and sharpness levels are respectable with the primary lens
  • The ultra-wide sensor, like on any budget phone, is a good addition - it takes social media-worthy images in great lighting conditions (in low-light, the quality dips and pictures look grainy and noisy, wide-angle shots also have barrel distortion at the edges)
  • Live Focus shots are quite good and the camera app does give you the option to set the level of blur before taking a shot - edge detection is very good and the Galaxy M21 does a good job of separating the subject from the background
  • The 20MP selfie camera is quite good and takes detailed selfies (though, in low light, the quality goes down a notch and results are grainy)
  • Monster 6000 mAh 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
  • If you're someone who consumes a lot of content on their phone, the Galaxy M21 is a good phone for you, it has great AMOLED display, outstanding battery backup that will last you for days
  • Looks stunning, with an all-glass design - Xiaomi has gone the extra mile here and really knocked it out of the park in terms of an exquisite design
  • Excellent, flagship-worthy, premium build quality
  • Great hand feel
  • The front and the back are fitted with Corning's Gorilla Glass 5 with an additional 0.8mm-thick layer for extra durability
  • The LED notification light sits comfortably on the chin - it can only be seen when it lights up, it's really subtle
  • Splash resistant body
  • The capacitive fingerprint sensor is easy to reach with your index finger and it also has a different texture, so it's hard to miss - plus it's quick
  • Apart from the quick fingerprint sensor, the phone also has decently quick AI face recognition (under good light)
  • Big 6.3inch LCD screen with fairly thin side bezels - and a small, unobtrusive notch
  • Good overall display quality, with especially good brightness levels - though it's not quite as good as the AMOLED panel on the Galaxy M30 - that's the one area where the Samsung phone takes a clear lead
  • You also get software tweaks to adjust the contrast and colour temperature, which is nice
  • Xiaomi's custom skin overlay, MIUI, has come a long way and the latest version takes a more simplistic and clean approach
  • There is also an option to chose between the standard navigation buttons and navigation gestures
  • The powerful Snapdragon 675 SoC makes sure that the device runs super smooth without performance drops even with complex games - everything is fast and lag-free - this is best-in-class performance for this price segment
  • The primary camera is the rear dual camera setup is a huge 48MP sensor - which shoots 12MP at default settings (there is a way to shoot in the sensor's full 48MP resolution if you prefer that, but you'd have to go to the camera's Pro mode for that)
  • In daylight, the performance is good, as expected - there's plenty of detail, contrast is good, colors are punchy, and noise is virtually non-existent
  • The actual benefit though of the large sensor is that users get sharper 12MP photos with less noise even at high ISO values compared to the regular 12MP sensors - what that means is that the night time shots are the real strong point of the phone, and are surprisingly good for a phone at this price point - there's no prominent noise, details are good and light sources appear to be rather well-preserved
  • Additionally, the Night mode really makes a difference by restoring the highlights and bringing out the shadows - the result is nicely balanced and subjects look more detailed
  • Portraits with the dual rear cameras are also very good - comparable to much more expensive handsets - the detail is nice while the edge detection is stellar - indoor portraits are good too
  • With the front camera, the selfies turn out to be quite nice as well - there's enough detail from the 13MP snapper and its focus sweet spot is almost a full arm's length so you don't need to get really close to the phone to get the sharpest possible result - the portrait mode also seems to do quite well despite the hardware limitations of the front camera (no secondary unit for depth sensing)
  • Overall, the cameras on the Redmi Note 7 Pro are top-notch, and this is now the camera package to beat in the under Rs. 20k price segment
  • Despite having just a single bottom-firing loudspeaker, the handset impresses with a loud sound - and it sounds clean at high volumes as well
  • Audio quality via headphones is very good too - and loudness remains just as impressive when headphones come into play - one of the highest in the market, let alone the price range
  • Has a modern USB Type-C port
  • Like other Redmi phones, the Note 7 Pro also packs a handy IR blaster, which can be used for remote controlling home appliances via the Mi Remote app
  • Excellent battery life, as has been the hallmark of the Redmi Note series - the 4000 mAh battery paired with the fairly efficient Snapdragon 675 SoC makes sure that it easily overtakes some upper-mid-range and high-end smartphones when it comes to endurance - you will comfortably get a 1.5-2 days of use
  • The Redmi Note 7 Pro is yet another winner from the Xiaomi camp, again going on to redefine the expectations of a budget phone
  • It's main competition will likely come from the Realme 2 Pro - and here the Redmi Note 7 Pro takes the lead with more premium glass build, faster processor, better battery life and more capable camera
2-minute Review [Negatives]
  • The power button and volumes are quite flush with the frame which means they lack that tactile, clicky feel
  • Design feels a bit dated and underwhelming, there is no spark in Galaxy M21's design as we see in other brand's phones like Xiaomi and Realme
  • However, this is an old chipset and heavy gaming isn't best on this phone - the Redmi Note 9 Pro and the Realme 6 are much better options that will handle gaming better than the Galaxy M21
  • Photos taken in low-light are average - focusing gets worse in low light and the extreme noise-correction makes images look like water paintings
  • Overall, the cameras on the M21 are decent, but there are better cameras available in this price bracket, including the Galaxy M31, which is just a tad bit pricier
  • Samsung Galaxy M11 falls behind in fast charging as competitors are offering close to 30W fast charging, the 15W on M21 feels low
  • Having said that, the Redmi Note 9 Pro and the Realme 6 will still offer you more bang for your buck, overall and when it comes to intensive tasks like gaming, you’ll be better off choosing the Realme 6 or the Redmi Note 8 Pro that are probably the best phones for gaming in this segment
  • At 186g, it's a bit on the bulky side
  • There continue to be pesky ads in the MUIU interface these days, and these do somewhat diminish the experience of using an otherwise excellent smartphone (there are ways to disable these through settings, but not a lot of people who buy the phone are going to be technically aware enough to know how to do that)
  • While the smartphone supports Quick Charge 4.0, the included adapter maxes out at 5V/2A, and though it has a decent charging speed (about 57% in 1 hour), you will have to look for a QC 3 or QC 4-capable brick to enjoy true 'fast charging'
