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

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
