Review of the Samsung A21

Samsung is most renowned for its large, powerful, and exorbitantly priced smartphones. But, in today’s Galaxy lineup, what does $250 get you? Getting your mind around Samsung’s cheap products is obviously challenging given their complex naming strategy and year-over-year model revisions, but the Samsung A21 is one of the Korean manufacturer’s latest price-conscious phones. It’s now available on a variety of US carriers, including Boost, which is where we tested the phone. While the A21 has a large screen and reasonable battery life, the phone’s overall performance and cameras (for the price) should cause budget-conscious big-phone enthusiasts to think twice.

Hardware and design

The Samsung A21 is massive – it’s slightly taller and wider than the S20 Ultra (although the Ultra is thicker). The A21 lacks the luxury screen-to-body ratio of its more costly cousin; whereas the S20 Ultra has a 6.9-inch display, the A21 has a marginally smaller 6.5-inch display. Its bezels, on the other hand, are scarcely distracting, especially in this price range. The hole-punch selfie camera placed into the upper left corner is also unobtrusive.

The screen is an IPS LCD display that’s lovely and bright, but it’s only 720p, which isn’t great at this size, with 270 pixels per inch. It also does not get nearly light enough to be used outside on a sunny day. There’s also a slight shadow surrounding the hole punch selfie cam, which isn’t especially bothersome when you’re not looking for it.

The volume and power buttons are located along the phone’s right edge, and while the power button is at a good height, the volume controls are far too high on the phone’s plastic frame. You’ll have to wriggle the phone down in your hand to adjust the volume unless you have exceptionally lengthy feelers. The fingerprint scanner on the back of the phone is similarly out of reach – when holding the phone in a natural stance, my index finger just barely reaches the bottom of the sensor. This is not a phone for the faint of heart.

The phone’s bottom edge houses a USB-C port, a 3.5-millimeter headphone jack (yay! ), and a single downward-firing speaker. All things considered, the speaker sounds fine. It’s not as tinny as I thought, but it’s located to the left of the USB port, making it extremely simple to conceal when holding the phone in landscape mode.

The A21’s rear panel, like its frame, is made of plastic. I have nothing against plastic phone bodies; glass is fragile and pricey. However, the plastic used by Samsung has a shiny, reflecting sheen, which means it gathers and shows oil from your hands incredibly well and holds up poorly to anything that feels like scratching it. Cases aren’t hard to come by, but the phone doesn’t come with one. Instead, it comes with a 12W power brick and a USB-A-to-C connection.

Software, performance, and battery life are all important considerations.

At this time, Samsung’s OneUI skin is well-known. However, if you haven’t used a Galaxy phone since TouchWiz, you’re good. The dialer, calculator, gallery, and so on in Samsung’s suite of apps lack the design elegance seen in their Google counterparts, and Samsung’s settings menus can be a touch hazy. OneUI, on the other hand, is mature and thoughtful. It has no jarring idiosyncrasies that detract from the experience, and I didn’t mind living in it throughout my time with the A21.

Unfortunately, the phone is overburdened with bloatware. Among the preloaded apps are Facebook, Amazon apps, Microsoft apps, two weather apps, and no less than four music streaming apps. Boost Mobile also had its way with my review unit, loading it with crap like a “secure Wi-Fi” utility — which, as constant notifications will remind you, requires an extra $2 per month to enable. There is no unlocked version of the phone, and I have to presume that other carriers are similarly oppressive.

Given the A21’s Mediatek Helio P35 chipset and three gigabytes of RAM, you wouldn’t expect it to be particularly fast – and you’d be correct. Multitasking is a chore, but the performance was never awful enough to irritate me, with the exception of the occasional program that took a few beats to start. The phone clearly struggles with more demanding games like Asphalt 9: Legends, but lesser titles like Mario Kart Tour work well.

The battery life is excellent. I managed to get roughly five and a half hours of screen time in two days of irregular mixed-use. The’s really good considering that period included gaming, streaming videos over Wi-Fi and 4G, taking photos, and idling for nine or so hours overnight.

Cameras

The Samsung A21 has a quad-camera arrangement, as the big branding adjacent to the sensors proudly proclaims. A 16.1-megapixel primary sensor, an eight-megapixel ultrawide sensor, a two-megapixel macro sensor, and a two-megapixel depth sensor are all included. The last two cameras are in total shambles. Many manufacturers have recently taken this approach: cram in a few of extra cameras and brag about how many you have.

Even in optimal lighting, images are faint and colors are distorted. Cropping a photo from the primary shooter is a better option.

But, given the A21’s pricing, I don’t mind the shots from the main and wide cameras. They can take some respectable photographs in good light, which is about all you can ask for in this price range. They do, however, struggle in other areas. Scenes with a high dynamic range are particularly difficult, with uniformly blown out highlights or crushed blacks. Low-light photography is also prohibited.

You might get some images that are decent on social media with a little patience and skillful editing but don’t anticipate any Pixel 4a-style price-defying miracles.

Some Advantages of the SAMSUNG A21

• The SAMSUNG A21’s advantages include dedicated external memory. We can install a quick memory MicroSDSX to keep images and videos at an external storage location.
• The advantages of the SAMSUNG A21 include the use of Android 10.0 as the factory default operating system. It is compatible with the Samsung ONE UI 2.0 user interface.
• The SAMSUNG A21 has a quad primary camera at the back with 16 MP for regular wide, 8 MP for Ultrawide, 2 MP for Macro, and 2 MP for DOF.
• The SAMSUNG A21 still has a 3.5 mm headphone jack. It is simple to connect to our existing headset or other external audio equipment.
• The battery capacity of the SAMSUNG A21 is 4000 mAh. This capability allows it to work for a longer period of time.

Some Disadvantages and limitations of the SAMSUNG A21

• The SAMSUNG A21’s front camera does not have an LED light flash. However, when taking images in low light conditions, we can still benefit from LCD brightness.
• The body of the SAMSUNG A21 is not water-resistant.
• The disadvantage of the SAMSUNG A21 is that it lacks an infrared sensor. This feature is typically used to replace the remote control for certain devices.
• The battery for the SAMSUNG A21 is not detachable. Because the body is unibody, the battery cannot be removed. Usually, after roughly 2 years of use, we need to replace the battery at an authorized repair center.
• The SAMSUNG A21’s flaw is that it lacks wireless charging capabilities. Wireless charging is typically found on high-end smartphones.
• The internal capacity of 32 GB and RAM of 3 GB is not very large, and this may be one of the SAMSUNG A21’s drawbacks.

Other SAMSUNG A21 Considerations

The SAMSUNG A21 has a 15W fast charging connector with a USB Type-C port, which allows it to swiftly charge its 4000 mAh battery. To accommodate the slim body of the SAMSUNG A21, the battery is not detachable.

Full-screen mode The front body measures 6.5 inches. The selfie camera is positioned in the right upper corner, through a little hole. Four vertical cameras with a single LED light flash may be found on the backside of the body. A fingerprint sensor can also be found on the backside of the body. The volume and power buttons are on the same left side.
