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
  • Well built, sleek, modern design, with a Infinity-U display
  • Eye-catching back panel with a gradient and prism-like finish
  • Large, vivid Super AMOLED, Infinity-U display with slim borders all around - everything looks colour accurate and bright
  • The Galaxy A30s runs on Samsung's new One UI, which is one of the more polished, refined takes on an Android UI, and is one of the best Android UI implementations at present, along with Oxygen OS
  • There are a number of useful features including Android Pie's Digital Wellbeing, and a whole bunch of motion gestures such as one-handed mode, Smart Stay, etc, which can be toggled on
  • Decent performance with a Exynos 7904 processor at the core (similar to Snapdragon 636) - day-to-day use is decent and complex games like PUBG are also playable at reduced graphics settings
  • Decent triple rear camera setup - primary 25MP sensor + 5MP depth sensor + 8MP ultra-wide sensor
  • The 25MP camera reproduces objects and panoramic scenes well, colours always look vivid - the edges of objects and textures lack clarity, though
  • The Primary camera can also take good macro shots - it capture more details than when in general shots, edges of objects are more distinguishable too
  • Good video quality - on par with that of other phones in this price range
  • Front camera shoots vibrant-looking portraits
  • Good Loudspeaker
  • Good call quality - it gets loud enough to make and receive calls from noisy environments
  • The 4000mAh battery is one of the Galaxy A30s's strong suits - you will easily manage to push past a full day on one charge
  • The bundled 15W fast charger is able to take the battery to about 70 percent in an hour, which is not bad at all
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 fingerprint sensor is sluggish - and cannot recognise fingerprints accurately
  • The Galaxy A30s is also a big phone to carry around, even if you have large hands
  • The resolution is only 720p which is rather low by today's standards
  • Unfortunately, there are still plenty of promotions, and ads to deal with, in the default phone setup
  • Given however, that other phones in this price range now come with much more powerful SoCs like the MediaTek Helio G90T and the Qualcomm Snapdragon 675, the A30s does lag behind the competition in terms of performance
  • The front 16-megapixel selfie camera is average - selfies are a bit soft in daylight and in low-light, selfies lack good detail, with visible grain
  • Camera struggles in low-light conditions - it captures hardly any details and underexposes the whole scene, with a lot of noise
  • Camera app does not have a slow-motion mode
  • Overall, the A30s is not quite as good as Samsung's other recent launches in the M and A series
  • It will face very stiff competition from the likes of the Redmi Note 8 Pro, which apart from being much more powerful, also takes a big lead in the camera department
  • Even if you want to stick to Samsung, the M30s will give you a slightly better camera performance, a bigger battery, and storage - so, significantly better value
