Samsung Galaxy A51 5G (2020), A Complete Review of Samsung’s Affordable 5G Powerhouse

When Samsung Galaxy A51 5G launched in April 2020, it marked a major shift in the mid-range smartphone market, bringing next-generation 5G connectivity to a wider audience at a much more accessible price. Positioned as an upgrade to the popular Galaxy A51, this device wasn’t just about faster internet; it delivered meaningful improvements in performance, battery life, and future-ready connectivity. In this detailed review, we’ll explore everything you need to know about the Galaxy A51 5G, from design and display to performance, camera, pricing, and how it compares to the Galaxy A51 5G UW variant.    

Design & Build Quality

Samsung continues its signature premium design approach with the Galaxy A51 5G. At first glance, it looks almost identical to its 4G sibling, but subtle refinements make it feel more solid and modern. The phone features:

• Glass front with Gorilla Glass 3 protection
• Plastic back with a glossy “Prism Cube” finish
• Aluminum frame for added durability
• Slim profile at 8.7mm thickness and 187g weight

The geometric patterns on the back reflect light beautifully, giving the phone a premium aesthetic despite its mid-range positioning.    

Comparison with Galaxy A51 5G UW (Design & Build)

The Samsung Galaxy A51 5G UW is nearly identical in design but slightly heavier and thicker due to mmWave 5G hardware. It weighs about 188.8g compared to 187g on the standard model . In real-world use, the difference is minimal, but the UW version feels just a bit denser in hand. Otherwise, both devices share the same premium look, camera layout, and overall build quality.    

Display: Immersive Super AMOLED Experience

Samsung rarely disappoints with displays, and the Galaxy A51 5G is no exception. It comes with a:

• 6.5-inch Super AMOLED display
• Full HD+ resolution (1080 x 2400 pixels)
• 20:9 aspect ratio
• ~405 ppi pixel density

The Infinity-O punch-hole design keeps bezels minimal, offering an immersive viewing experience perfect for streaming, gaming, and browsing. Colors are vibrant, blacks are deep, and brightness levels are excellent, even outdoors. For a 2020 mid-range device, this display competes with some flagship screens.    

Performance: Powered by Exynos 980

Under the hood, the Galaxy A51 5G is driven by the Exynos 980 chipset, Samsung’s first mid-range processor with integrated 5G support. Key specs include:

• Octa-core CPU (2x Cortex-A77 + 6x Cortex-A55)
• Mali-G76 GPU
• 6GB or 8GB RAM
• 128GB internal storage (expandable via microSD)

This setup delivers smooth everyday performance. Apps launch quickly, multitasking is seamless, and gaming performance is solid for titles like PUBG Mobile and Call of Duty Mobile. Compared to the 4G version, the 5G model offers a noticeable performance boost, making it more future-proof.    

5G Connectivity: The Big Selling Point

The standout feature here is, of course, 5G support. The Galaxy A51 5G supports:

• Sub-6GHz 5G bands
• Faster download and upload speeds
• Lower latency for gaming and streaming

While 5G coverage in 2020 is still developing, this phone ensures you’re ready for the future as networks expand globally. The Galaxy A51 5G UW, however, adds mmWave 5G support, making it faster in supported regions, but also slightly bulkier.    

Camera System: Versatile Quad Camera Setup

Samsung equips the Galaxy A51 5G with a flexible quad-camera system:

• 48MP main camera
• 12MP ultra-wide lens
• 5MP macro lens
• 5MP depth sensor

Camera Performance

• Daylight shots: Sharp, vibrant, and detailed
• Ultra-wide: Great for landscapes and group shots
• Macro: Fun but not always consistent
• Portrait mode: Good edge detection

On the front, you get a 32MP selfie camera capable of 4K video recording, which is impressive for a mid-range device. Video recording supports:

• 4K at 30fps
• Full HD slow motion

Overall, the camera system is versatile and reliable, though low-light performance could be better.    

Battery Life: All-Day Power

Battery life is another strong point.

• 4500mAh battery
• 15W fast charging

With moderate use, the Galaxy A51 5G easily lasts a full day. Whether you’re streaming, browsing, or gaming, the battery holds up well. Charging isn’t the fastest compared to flagship devices, but it’s acceptable for its category.    

Software & User Experience

Out of the box, the phone runs:

• Android 10
• Samsung One UI 2.0 (upgradeable to Android 13)

Samsung’s One UI is clean, intuitive, and packed with useful features like:

• Dark mode
• Edge panels
• Digital wellbeing tools

The interface is smooth and user-friendly, making it suitable for both beginners and advanced users.

• United States: $499
• United Kingdom: £429
• Nigeria: ₦190,000 – ₦220,000 (approx at 2020 rates)
