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
  • Fresh, sophisticated and premium-looking rear design - it features a pattern of vertical pinstripes down the rear that seem to shift from side to side when you move the phone around under the light
  • Front looks slick with a dewdrop notch at the top
  • It's relatively easy to use and live with because of its tall and narrow footprint
  • The fingerprint reader is on the back and performs well
  • Large 6.5-inch HD+ display - it's crisp enough for gaming and video streaming
  • Software is one area where Realme has taken a big leap, the Realme UI is easy to use - it is also packed with features such as Game Space, Digital Wellbeing, Focus Mode, Dark Mode, and Riding Mode among others
  • Good performance from the new MediaTek G80 chipset (similar to the Snapdragon 712) - the phone smoothly handles day-to-day task with ease and heavy games like PUBG Mobile run reasonably well
  • Decent quad-camera setup at the back - a 48MP primary camera, a 8MP ultra-wide, a 2MP macro and a 2MP depth sensor
  • Shots with primary camera, under bright sunlight have lots of detail and exposures are well balanced - it works well for casual photography
  • The ultra-wide-angle camera delivers fairly decent shots and captures more of the scene in the frame, as long as there is good lighting
  • The portrait mode works well with well defined subjects and natural looking bokeh
  • The selfie camera is decent - it also takes quite good portraits
  • Excellent battery life with the 5000 mAh battery - it easily lasts for 2 days of moderate use
  • Decent fast charging with the supplied 18W charger - it fills the phone's battery to the brim in about 2 hours
  • The Narzo 10 is a very strong contender if your priority is performance and battery life, and for its target audience, which are gamers, these are the things that matter
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
  • A bit thick at 9mm and relatively hefty at 199g
  • Competition offers better displays with FHD+ resolution
  • The display isn't particularly bright and could be a problem to use in direct sunlight
  • There are still a number of pre-loaded apps however - though most of these can thankfully be uninstalled
  • Low-light photography is just average, as expected from a budget phone
  • Macros are blotchy and rough, with the limited resolution, this camera should be used more for fun than anything else
  • However, if you can spend a little more, you might want to consider the Realme 6 and the Redmi Note 9 Pro instead, as they offer much better performance and cameras
