As I mentioned earlier, the Galaxy A21s comes with a quadruple-camera array, consisting of a main 48MP (f/2.0) lens, supported by an 8MP (f/2.2) wide-angle unit, 2MP (f/2.4) macro camera and a 2MP (f/2.4) depth sensor. A 13MP (f/2.2) selfie camera sits on the front of the phone. Still, for the price, you can’t grumble too much, and the Galaxy A21s’ screen manages to excel in other areas. The display reached a maximum luminance of 553cd/m² on the adaptive brightness setting, the contrast ratio is rather good at 1,267:1, and viewing angles aren’t too shabby, either. Samsung Galaxy A21s review: Performance and battery life It’s a similar story when it comes to graphics processing. The Galaxy A21s manages to close the gap slightly, but it still lags behind the others. The lower-resolution screen does help boost performance, however, and I didn’t notice any glaring issues in less demanding games such as Stardew Valley and Gris.

Unusually for a Samsung phone, there aren’t multiple display profiles to choose from, and sadly what we get isn’t all that special. In technical testing, it covered 73% of the sRGB colour gamut, with a total volume of just 84%. Colour accuracy isn’t up to scratch either, with a measured Delta E of 4.23. Some colours, such as light green and dark red tones, looked particularly dull.

If you care about battery life, which I would argue is a far more important metric, then you’re in for a real treat with the Galaxy A21s. In our standard battery-rundown test, where we set the screen to 170cd/m², switch on flight mode and play a looped video, the Galaxy A21s lasted 22hrs 48mins. That’s more than five hours longer than the next best phone in the graph, the Realme 6.
