The Samsung Galaxy A51: A Solid Mid-Range Contender

The Samsung Galaxy A51: A Solid Mid-Range Contender

Design and Display

The Samsung Galaxy A51's design bears a striking resemblance to its predecessor, featuring a plastic build with a familiar finish that reflects an array of colors in certain lighting conditions. The notable change comes in the form of the new L-shaped quad-camera setup at the rear. Despite its large 6.5-inch Super AMOLED display with a 1080p resolution, the phone remains slim and lightweight, offering a comfortable grip and a sleek appearance.

Display Quality

The 6.5-inch Super AMOLED display delivers a remarkable viewing experience with sharpness, vibrant colors, and impressive contrast. The absence of a notch is compensated by a punch hole for the selfie camera, ensuring an immersive display with minimal obstructions. Additionally, the display's brightness reaches over 400 nits with a manual slider and approximately 613 nits in bright conditions with the auto mode enabled, guaranteeing clear visibility in various environments.

Additional Display Features

  • Accurate color settings
  • Respectable brightness levels
  • Always-on display for time and notifications
  • In-display fingerprint reader for added convenience


The Samsung Galaxy A51's single loudspeaker provides decent sound quality, while the 3.5mm audio jack offers excellent audio output with ample volume and minimal distortion. Additionally, the phone supports expandable storage, allowing users to store a vast library of media and content without compromising on audio quality.

Software and User Experience

The Samsung Galaxy A51 comes with Samsung's latest 1UI 2.0 over Android 10, offering a range of new features including a dark mode for menus and a new set of gestures for navigation. The inclusion of edge panels provides a customizable space for shortcuts, enhancing the user experience.

Chipset and Performance

At the heart of the A51 is Samsung's new Exynos 9611 chipset, which performs comparably to the Snapdragon 660 in CPU tests but falls short in GPU tests. Unfortunately, the A51's performance scores are lower than the majority of its competitors, impacting its overall user experience.

Battery Life and Charging

The Samsung Galaxy A51 scored an endurance rating of 86 hours in battery tests, which is decent but falls short compared to the previous year's model. In today's mid-range market, this performance is not particularly exceptional.

Charging Speed

When using the bundled 15-watt adapter, the charging speed of the Galaxy A51 is average. It was able to charge from 0 to 35% in half an hour, which is neither impressive nor disappointing.

Camera Setup and Image Quality

The Galaxy A51's quad-camera setup marks a significant change from its predecessor, featuring a 48-megapixel main camera, a 12-megapixel ultra wide-angle camera, a 5-megapixel macro camera, and a depth sensor. The camera performance in various scenarios is as follows:

Main Camera

  • Decent pictures with good sharpness, wide dynamic range, low noise, and balanced colors in daylight
  • Issues with rendering fine details and limited benefits when shooting in full 48 megapixels

Ultra Wide-Angle Camera

  • Capable performance for a mid-range device with good sharpness and dynamic range
  • Significant upgrade from the previous model

Portrait Mode

Excellent subject detection and separation with a pleasing defocused background blur, making portraits taken with the main camera stand out.

Macro Camera

The dedicated macro camera has fixed focus, making it challenging to get the subject in the focus sweet spot. However, when successful, the results can be pretty decent.

Low-Light Performance

  • Soft and noisy photos with washed-out colors in low-light conditions
  • Night mode provides a sharper image with better shadow definition, although the color rendition remains consistent
  • Ultra wide-angle camera struggles in low-light conditions, resulting in soft, dark, and noisy photos

Selfie Camera and Video Recording

The Samsung Galaxy A51 boasts a 32-megapixel selfie camera that delivers impressive 12-megapixel photos with excellent colors, dynamic range, and detail. Notably, the device offers the rare feature of 4K video recording from the selfie camera, providing videos with good exposure. However, the stabilization could be improved to enhance the overall video quality.

When it comes to video recording, the Galaxy A51 can capture up to 4K at 30fps with its main camera and ultra-wide cam. Footage from the main camera exhibits accurate colors and wide dynamic range, although it may appear slightly over-processed. On the other hand, the ultra-wide-angle camera's footage displays slightly washed-out colors and lower contrast, but still maintains decent dynamic range. Stabilization is available for 1080p recording from the main camera, while footage from the ultra-wide camera offers super smooth stabilization.

Overall Impressions

The Samsung Galaxy A51 offers a beautiful and lightweight build, a stunning AMOLED display, and a versatile set of cameras, making it an attractive option in the mid-range market. However, certain drawbacks, such as average battery life and charging speed, an okay chipset, and a relatively high price point, may deter potential buyers. While the device has its strengths, there may be better options available in the market for those seeking a comprehensive mid-range smartphone experience.


The Samsung Galaxy A51 is a compelling mid-range smartphone that offers a sleek design, vibrant display, and a versatile camera setup.
