Galaxy A51 vs Galaxy S21 FE 5G

The Samsung Galaxy A51, released in December 2019, and the Samsung Galaxy S21 FE 5G, launched in January 2022, are Android smartphones from different segments of Samsung's lineup. While both offer a comprehensive smartphone experience, the Galaxy S21 FE 5G introduces more advanced features and performance capabilities, reflecting its newer release and higher-tier positioning. Both devices operate on the Android platform, offering access to a wide ecosystem of applications and services.

The practical lifespan of a smartphone is significantly influenced by its release date and subsequent software support. These two devices, separated by over two years, offer different expectations in this regard.

• Release Timeline: The Galaxy A51 was initially released in December 2019, with a 5G variant following in April 2020. The Galaxy S21 FE 5G arrived later, in January 2022.
• Software Longevity: The Galaxy A51 (4G variant) has reached the end of its software support cycle, with its last major Android update being Android 13. The 5G variant also received updates until Android 13. The Galaxy S21 FE 5G, being a newer device, benefits from a longer update commitment, with users reporting updates up to Android 14 and an expectation of continued support for a longer duration.
• Durability Features: The Galaxy A51 features Corning Gorilla Glass 3 for screen protection. The Galaxy S21 FE 5G offers enhanced durability with Corning Gorilla Glass Victus and an IP68 rating for dust and water resistance, providing better protection against environmental elements.

The performance of these devices varies considerably, largely due to the difference in their internal components and release timelines. The Galaxy S21 FE 5G offers a more robust experience for demanding tasks.

• Processing Capabilities: The Galaxy A51 handles everyday applications and light multitasking smoothly. However, for more intensive tasks like graphic-heavy gaming or running multiple complex applications simultaneously, users may experience slower loading times and occasional stutters. The Galaxy S21 FE 5G, equipped with a more advanced processor, delivers a significantly faster and more responsive experience, excelling in demanding applications, multitasking, and high-performance gaming.
• Multitasking and Responsiveness: The Galaxy A51, with its available RAM configurations, is suitable for typical daily usage, but heavy multitasking can lead to some slowdowns. The Galaxy S21 FE 5G, with higher RAM options and a more powerful processor, maintains smoother operation even with numerous applications open, providing a more fluid user interface.
• Storage Options: The Galaxy A51 offers expandable storage via a microSD card, providing flexibility for users who need to store large amounts of data. The Galaxy S21 FE 5G does not support expandable storage, meaning users must rely on the internal storage options available at purchase.

Both devices feature vibrant AMOLED displays, but the Galaxy S21 FE 5G incorporates newer display technology for a more refined visual experience.

• Display Technology and Clarity: The Galaxy A51 features a 6.5-inch Super AMOLED display, offering rich colors and deep blacks suitable for media consumption. The Galaxy S21 FE 5G comes with a 6.4-inch Dynamic AMOLED 2X display, which provides enhanced color accuracy, deeper contrast, and improved outdoor visibility. Both offer Full HD+ resolution, ensuring sharp visuals for text and images.
• Refresh Rate and Smoothness: The Galaxy A51 has a standard 60Hz refresh rate, which provides a smooth enough experience for most users. The Galaxy S21 FE 5G features a 120Hz refresh rate, resulting in noticeably smoother scrolling, more fluid animations, and a more responsive feel during interactions and gaming.
• Screen Protection: The Galaxy A51 is protected by Corning Gorilla Glass 3. The Galaxy S21 FE 5G utilizes the more advanced Corning Gorilla Glass Victus, offering greater resistance to scratches and drops.

The camera systems on these two smartphones cater to different photography needs, with the Galaxy S21 FE 5G offering a more versatile and advanced setup.

• Rear Camera System: The Galaxy A51 features a quad-camera setup with a 48-megapixel main sensor, a 12-megapixel ultrawide, a 5-megapixel macro, and a 5-megapixel depth sensor. The Galaxy S21 FE 5G has a triple camera system, including a 12-megapixel main sensor with optical image stabilization (OIS), a 12-megapixel ultrawide, and an 8-megapixel telephoto lens with 3x optical zoom. While the A51 has a higher megapixel count on its main sensor, the S21 FE 5G's larger sensor size and OIS often translate to better low-light performance and more stable video.
• Photography Performance: The Galaxy A51 performs well in good lighting conditions for everyday photos. The Galaxy S21 FE 5G generally produces sharper images with better detail and dynamic range, especially in challenging lighting, and its telephoto lens provides greater zoom capabilities without significant loss of quality.
• Video Recording and Front Camera: Both devices feature a 32-megapixel front camera for selfies and video calls. The Galaxy S21 FE 5G supports 4K video recording at 60 frames per second on its main camera, offering higher quality video capture compared to the A51.
