In the ever-evolving world of smartphones, Samsung has been a dominant force, consistently releasing innovative and high-quality devices. In this article, we will compare two of their mid-range offerings - the Samsung Galaxy A51 and the Samsung Galaxy A55 5G.
Samsung Galaxy A51: Released in December 2019, the Samsung Galaxy A51 is a mid-range smartphone that packs a punch in terms of design, hardware, and camera capabilities. The device features a Super AMOLED display measuring 6.50 inches with a resolution of 1080x2340 (FHD+). The screen-to-body ratio is an impressive 88.5%, providing users with an immersive viewing experience.

Additionally, there is support for external storage via an SD card.
The camera setup on the Samsung Galaxy A51 is another standout feature, with a quadruple camera system at the rear. This includes a 48.0-megapixel standard lens, a 12.0-megapixel wide-angle lens, a 5.0-megapixel portrait mode lens, and a 5.0-megapixel macro lens.

The device also comes equipped with stereo speakers, Hi-Res Audio, and Dolby Atmos for an immersive audio experience.
In terms of design, the Samsung Galaxy A55 5G combines aluminium and plastic materials, providing a balance between durability and weight. The device is protected by Corning Gorilla Glass Victus, one of the toughest glass solutions available in the market. The usable surface of the phone stands at 85%.
Under the hood, the Samsung Galaxy A55 5G is powered by the Exynos 1480 processor, built on the 4nm process technology for improved efficiency and performance. The device comes in two RAM options - 8GB and 12GB, paired with storage options of 128GB or 256GB. External storage is supported via a MicroSD card slot in the tray.
The camera setup on the Samsung Galaxy A55 5G includes a triple camera system at the rear, featuring a 50.0-megapixel standard lens, a 13.0-megapixel wide-angle lens, and a 5.0-megapixel macro lens. The device also boasts a 32.0-megapixel front-facing camera for selfies. Optical stabilization (OIS) is included for smoother video recording.
