Product Information

A rear-mounted fingerprint sensor also sits in the centre, which can be used to unlock the phone and authorise contactless payments. It will continue to compete against the bloated list of phones in Samsung’s fleet, as well as from budget hallmarks such as Xiaomi and Motorola, but the Galaxy A21s manages to exceed expectations. uk/browse/technology/mobile-phones-and-accessories/sim-free-phones/c:30147/brands:samsung/" on this server. On a swelteringly hot day in London, the main camera took a suitably bright photo of the canal boats docked in Poplar Marina, as well as the families of geese and swans nesting nearby. It’s not the flashiest phone on the market, nor is it the cheapest, but where it counts the new Galaxy A21s is a reliable choice for anyone hoping to upgrade without having to spend much money.

The Galaxy A21s is powered by Samsung’s homebrew Exynos 980 chipset, with a maximum clock speed of 2GHz, backed by 3GB of RAM. Due to current lockdown restrictions, I was unable to directly compare the two phones in the same scene, but the Galaxy A21s managed to take a pretty good picture, regardless.

Aside from the slightly weaker aperture on the main camera, the Galaxy A21s’ composition of cameras is identical to that of the Xiaomi Redmi Note 9. It takes 12MP images by default – the 48MP option is located in Pro mode – but both settings managed to produce wonderfully detail-rich images with plenty of vibrancy.

You can’t expect the same speeds as its Qualcomm and MediaTek-based rivals, but the Galaxy A21s rarely felt unresponsive or sluggish.

The back of the phone is slightly curved, with the four cameras and LED flash arranged in a tidy rectangle in the top-left corner. Somehow, Samsung has managed to squeeze in a total of five cameras, which is rather remarkable given how little it costs. This isn’t great by modern standards, especially since the Xiaomi Redmi Note 9 and Realme 6 both benefit from pixel-packed Full HD screens.
