2-minute Review [Positives]
  • Looks sleek and eye-catching with its iridescent finish - the plastic back has this rainbow-like effect
  • The front looks trendy with minimal screen bezels and an unobtrusive hole-punch in the top-left corner
  • Samsung has gotten the software part on point with its recent launches, with it's new One UI, that's now one of the better, more streamlined Android skins around - it's especially well suited for big displays like this, packs an intuitive gesture navigation system, and other useful things like a convenient 'dark mode'
  • Good quadruple-camera array - a primary 48MP lens, supported by an 8MP ultra-wide angle unit, 2MP macro camera and a 2MP depth sensor
  • The Galaxy A21s manages to take a pretty good picture from the primary camera - it produces wonderfully detail-rich images with plenty of vibrancy
  • Live Focus mode (portrait mode) allows adjusting the level of blur either before, or after, you press the shutter button, and the results are good
  • Macro mode is also a lot of fun - it captures some crisp closeups
  • Excellent battery life with the 5000 mAh cell - combined with a low-res screen and a power-efficient CPU, it would easily last you for 2 days of moderate use
  • Supports 15W fast charging
  • 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]
  • Average 6.5-inch TFT LCD - the HD resolution is rather low for a phone at this price, and the colour reproduction isn't great
  • The Galaxy A21s is powered by Samsung's new Exynos 850 chipset, which gets things done and that's about it - it doesn't compete with the powerful processor other phones offer and heavy games are a no go
  • Overall, the Galaxy A21s has quite capable cameras, though they aren't the class-leading
  • On the whole, while the Galaxy A21s is a fashionable choice for the price bracket, and does exceptionally well with battery life and a decent set of cameras - however, it falls a bit behind in terms of performance and display - you will find better all-round options from the likes of Xiaomi, Realme and Motorola
  • 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
