Size and screen

A21s vs A20s size

Samsung A21s: 6.5-inch HD screen with Gorilla Glass

The Samsung A21s has a large 6.5-inch HD screen. You can't watch movies in high quality on this screen, but it's sharp enough for apps like WhatsApp and Facebook. The Gorilla Glass protects the touchscreen from scratches and cracks. This is useful when you put the device in the same pocket as your keys. If you have small hands, it's hard to operate the device with one hand. Are you looking for a smaller smartphone? Have a look at the Samsung Galaxy A41.

Samsung A20s: same screen, no Gorilla Glass

The 6.5-inch HD screen of the Samsung A20s is just as large as that of the A21s. This means this device is also hard to operate with one hand. Contrary to the A21s, this smartphone doesn't have Gorilla Glass. So the screen is less well protected from scratches and cracks. In terms of resolution, the screen is comparable to the A21s. Sharp enough for basic tasks, but less suitable for movies. Are you looking for a sharper screen? The Samsung M21 is a good alternative.


Samsung A20s or A21s camera

Samsung A21s: 3 lenses, basic quality photos

The cameras of the Samsung Galaxy A21s are fine if you mainly take pictures to share via WhatsApp or occasionally post one on Facebook. But the quality of the cameras isn't good enough to take pictures for your vacation photobook. In addition to the 48-megapixel standard lens, this smartphone has a wide-angle lens. With this, large buildings and groups fit completely in your picture. With the macro lens, you can also clearly capture objects up close from a few centimeters.

Samsung A20s: 2 lenses, poor photos

You don't buy the A20s for the quality of the photos. With its dual camera at the back of the device, you can mainly take functional photos. These aren't very sharp. In addition to the 13-megapixel standard camera, the A20s has a wide-angle lens. Thanks to the large viewing angle of the camera, that large church or sweeping landscape completely fit in your photo. Just like the A21s, this device has a depth sensor. Since this sensor measures depth, you can create a depth of field effect in portrait photos, for example.


Samsung A21s vs A20s processor

A21s: suitable for standard use, 5000mAh battery

The A21s has 2 storage capacity versions. A version with a limited 32GB storage and a version with 64GB storage. That latter version doesn't only have more storage, but more RAM as well. Thanks to this, you can switch between different apps faster. With the Exynos 850 processor, the A21s is suitable for standard use. Texting via WhatsApp, using the internet, and basic games such as Candy Crush are no problem. The large 5000mAh battery lasts one and half day without charging. The included charger allows you to charge the A21s fast.

A20s: basic tasks only, 4000mAh battery

The 32GB storage capacity of the Samsung A20s doesn't offer a lot of space for your apps, photos, and other files. Just like with the A21s, you can expand this capacity with a memory card if you want. With a Snapdragon 4560 processor and 3GB RAM, the A20s is suitable for basic use. Tasks such as calling and texting are no problem for the device, but with apps like YouTube and games, this entry-level model will slow down. With the 4000mAh battery, you can make it through the day with normal use. The A20s has a fast charge function as well.


With the Galaxy A21s, Samsung has made some clear improvements compared to the A20s. The smartphone is more powerful and it has better cameras and a more powerful battery than its predecessor. Both affordable smartphones have a large 6.5-inch screen which is hard to operate with one hand. Do you only use your smartphone for calling and texting via WhatsApp? Then the A20s is sufficient. If you regularly use apps and surf the internet, the A21s is the better choice.
