The new Samsung Galaxy A21s is a budget smartphone catered for those of us looking for one that’s functional, does standard features, and is affordable. It comes with a 6.5-inch display, a 48MP quad-sensor camera at the back with a 13MP selfie camera in the display. It also includes a 5000mAh battery that comes with great battery life, and inputs such as a headphone jack, and a MicroSD slot to expand storage. Let’s explore the A21s in more detail. 



What’s to like


There are lots of things to like here from the Samsung Galaxy A21s. 

Firstly, the phone comes with a large 6.5-inch display with a 1600 x 720p resolution. It’s not the sharpest display but acceptable within budget smartphones. The brightness and colour accuracy looks average but it works well. Overall, the A21s comes with a standard, functional but large display.


Next is the great battery life. On moderate use, the A21s can last you a good 5 days of usage on a single charge, and up to 25 hours of battery life on normal usage. In short, if you minimize the use of apps and other features that consume more battery life, you can experience one of the best budget phones with long battery life.

Thirdly, the phone comes with a 48MP quad-camera, that includes an 8MP ultrawide, 2MP macro, and 2MP depth camera sensors. The selfie camera comes with a 13MP selfie camera. Overall, the A21s produces good-quality pictures and good-quality full HD videos. Not as smooth but still looks good.

Next is the design. Nothing special except for the three innovative design colors available and that glossy look that makes it look really attractive. The fingerprint scanner is at the back. Otherwise, the phone looks good with an attractive design.    

Lastly, the A21s has a MicroSD card to expand storage and a headphone jack to plug in earphones. those are scarce nowadays with even in the top range phone market.

In short, the A21s come with some good features. The attractive design, the large display, the long battery life, the quad-camera, and other features to expand storage, and the inclusion of a headphone jack. But before you decide to click to purchase the amazing Samsung Galaxy A21s, there are a few things to note.      



What’s not to like


To start off, the phone comes with an underpowered CPU. It’s been tested and has performed lower than the average below the average bu


Next, the build is made of plastic, encased with aluminum frame. It’s not the best in durability. So, no water or dust resistance. 

Thirdly, the A21s comes with a single speaker at the bottom of the phone that performs poorly. And the display quality is viewable but not top-grade stuff.

Next, the largest internal storage model available for the A21s is 64GB. That’s not really much storage in this day in age but at least you can add an SD card. So if you want to get bigger storage, get an SD card because the internal phone storage is low.

Lastly, the charger in the box is a 15W quick charger, but sadly it’s not that fast. For a full charge, you are looking at less than two hours. 

Overall, the A21s smartphone lacks performance, durability, sound and display quality, and storage. Luckily, you can expand storage thanks to MicroSD, and you can also use earphones to listen to calls and music thanks to the headphone jack. Yet it’s a budget phone so compromises are expected.





If you’re looking for a budget smartphone with a great battery life, an attractive design, takes good pictures and videos, comes with a MicroSD slot, and a headphone jack, then the Samsung Galaxy A21s is definitely for you. For those reasons I highly recommend it. It’s really affordable at a price range of about US$200.  

If you’re looking for a budget smartphone with good overall performance, large internal storage, and more durability options such as water resistance, you won’t it here. There are other budget smartphones to recommend such as the Redmi Note 9S, the Huawei P40, the 2019 Huawei P30 Lite, to name a few.  


Overall, the Samsung Galaxy A21s smartphone is not a bad phone. If you are happy with the pros and can tolerate to cons, then the Samsung Galaxy A21s is the phone for you. Click here to find out more.

    I always liked Samsung phones and I have owned many of theirs in the last 10 years. To be honest I never owned one of their A series as I was always going for their Galaxy S models but as I have been keeping an eye in all their releases the A series is amazing for a low cost phone and I would get it without hesitation if I wanted a cheap but reliable one.

      S-series Samsung phones are great and have so many features and technology for us to use. But now the A-series have also got good technology as well, but at a lower cost. They are great and functional smartphones for those looking for budget phones. Thanks for your comments. Much appreciated.

    I have a Samsung Galaxy s6 and I have problems with the display. I am seriously thinking of switching to a new Samsung.
    That’s why I find this article very useful for me.
    Samsung Galaxy A21s from what I read is suitable for me and my budget.
    I think a lot about video filming and the camera I think is very good for something like that.
    Thank you very much, I’m seriously thinking of making a change.
