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
  • 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
  • Decent 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 decent 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)
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
  • 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
