Samsung Galaxy A21s review – phonearena

Budget-friendly and mid-range phones are getting better and better, and with the economy all shaken up, They\’re becoming the more desirable option for a lot of people. Joining the budget-friendly crowd is the Samsung Samsung galaxy A21s: а gadget with a massive battery life and well-performing cameras. Now, we did encounter performance issues, and the LCD screen is not so color accurate, but if you’re looking for a nice budget-friendly smartmobile with solid battery life and a big display, the Samsung galaxy A21s might be a nice candidate for you. Read on to see what else we liked and disliked about this smartmobile.

Design & Display

Overall, the Samsung galaxy A21s has a simple and unobtrusive design. The smartmobile’s display is a 6.5-inch LCD panel, surrounded by thin bezels. On the right hand side of the screen there is a small punch-hole, housing the selfie camera. The dark blue color of our unit emits rainbow-like reflections when light hits it at certain angles. Other available colors for this model are white and black, nothing fancy. On the smartmobile’s plastic back, next to the quad-camera bump, we find the fingerprint sensor.

The A21s’ display is bright and vibrant; however, the colors are quite blue-ish and the viewing angles are not perfect, but this is to be expected from a budget mobile. The res of 1600 by 720 px is quite low for a 6.5-inch screen. Given the smartmobile’s rates, we were expecting to see a better screen, but we’d say the current one is passable.

Camera & Audio

The Samsung galaxy A21s comes with a quad-camera system: a 48MP main sensor, an 8MP ultra-wide camera, a 2MP depth sensor and a 2MP macro camera. The latter does not quite manage to take macro shots well, the main sensor succeeding better in this department.

Photos in nice lighting conditions turn out great, although colors are a bit more saturated than in real life. We see Samsung’s usual image processing present on this gadget: some people may find the vibrant, cheerful-looking colors nice, but they’re quite unrealistic.

The mobile has a portrait mode which Samsung calls Live Focus mode, and it does an okay job. Sometimes it struggles to determine which part is background and which part is just your subject’s hair or shirt, but other times it does great.

The A21s doesn’t have a night mode, so don’t count on those dark photos for your social media.

Speaking of social media, selfies turn out quite nice. The A21s is equipped with a 13MP selfie camera, coupled with Samsung’s usual beauty effect which I personally don’t mind (even when you turn the beauty filter off, there is some smoothening of the skin, so keep that in mind).

The ultra-wide shots are pretty similar to the ones taken by the main camera ‒ in bright light, colors are vibrant to the point of having a cartoon-ish vibe, but overall, photos are quite good-looking and lively. Dynamics are also nice on those.


In the video department, the A21s does a satisfactory job for its rates range, although it can only record FHD videos. good Colors on videos are fun and vibrant and the autofocus is pretty quick. Unfortunately, there’s no fancy 4K recording capabilities here to brag about.


Well, the Samsung galaxy A21s doesn’t offer stereo sound for YouTube videos and music and the loudspeaker is not quite loud for listening to in noisy environments, so don’t expect wonders from it. Luckily, the mobile has a 3.5 mm headphone jack so you can use your favorite pair of wired headphones.

Software & Performance

The Samsung Samsung galaxy A21s comes with Android 10 and Samsung’s proprietary One UI 2.1 on top. The software runs okay, although under heavy loads, such as gaming or running demanding apps, the smartmobile takes its time to complete its task.

The gaming experience is mediocre; if you’re really into mobile gaming, it may be better to go for a more strong mobile, given the fact that the A21s’s Exynos 850 processor is really slow in loading bigger games such as PUBG Mobile or Asphalt 9.

Apart from gaming, we generally enjoyed the performance of this smartmobile. One very helpful feature that Samsung has here is Focus Mode which helps you block out distractions from apps and helps with productivity. Overall, the mobile performs well with web browsing, social media consumption and watching video.
