Choosing the Best: Samsung Galaxy S7 Edge Vs Samsung Galaxy A42 5G
Choosing between the Samsung Galaxy S7 Edge and the Samsung Galaxy A42 5G in 2025 comes down to your personal preferences and priorities. The Galaxy S7 Edge carries Samsung’s legacy of premium curved design, vivid display, and flagship build quality. Meanwhile, the Galaxy A42 5G represents a newer generation of mid-range smartphones, offering 5G connectivity, a modern AMOLED display, and a longer battery life. If you want a phone that’s stylish, compact, and still capable, the S7 Edge remains a strong contender. But if you need future-ready 5G, updated hardware, and better software support, the Galaxy A42 5G takes the lead.
Display Comparison – Clarity, Brightness & Fluidity
The Galaxy S7 Edge features a 5.5-inch Super AMOLED curved display with QHD resolution, known for its sharp visuals and deep blacks. It delivers vibrant colors and excellent viewing angles. On the other side, the Galaxy A42 5G comes with a 6.6-inch Super AMOLED display with HD+ resolution and a flat design. While not as sharp as the S7 Edge, it offers larger screen real estate for multimedia and browsing. Both displays are capable, but the S7 Edge stands out in resolution and contrast, while the A42 5G excels in size and everyday usability.
Performance & Chipset – Exynos 8890 vs Snapdragon 750G
The Galaxy S7 Edge is powered by the Exynos 8890 or Snapdragon 820 (depending on region), which was flagship-level in its time. It handles basic tasks and light gaming reasonably well, even today. However, the Galaxy A42 5G, equipped with the Snapdragon 750G, brings more power efficiency, better AI integration, and 5G capability. While the S7 Edge was built for speed in 2016, the A42 5G is better equipped for modern multitasking, gaming, and network speed, making it the smarter choice for daily use in 2025.
RAM & Storage – Fluid Multitasking & Space
The Galaxy S7 Edge comes with 4GB of RAM and up to 128GB of storage, expandable via microSD. It handles essential tasks with ease but may struggle with intensive apps. The Galaxy A42 5G, on the other hand, offers 4GB or 6GB of RAM and 128GB internal storage, also expandable. Moreover, its newer memory management and software optimization make multitasking smoother. The A42 5G has an edge in storage flexibility and future-ready performance.
Battery & Charging – Endurance or Speed
The S7 Edge includes a 3600mAh battery with support for 15W fast charging and wireless charging, which was impressive for its time. However, battery endurance is limited by its age and smaller capacity. In contrast, the A42 5G features a 5000mAh battery with 15W fast charging, offering much longer screen-on time and better longevity. While both charge at similar speeds, A42 5G is the clear winner in battery life, making it more suitable for today’s on-the-go lifestyle.
Camera System – Pro-Level Photography Showdown
The Galaxy S7 Edge sports a 12MP single rear camera with Dual Pixel technology, known for its fast focus and great low-light performance in its era. It still holds up for casual shots. Meanwhile, the Galaxy A42 5G features a quad-camera setup with a 48MP main sensor, ultra-wide, macro, and depth sensors. It offers more versatility and better detail capture under various conditions. While the S7 Edge shines in low-light and point-and-shoot simplicity, the A42 5G delivers a broader photography experience for users today.
Software Experience – One UI vs TouchWiz
The S7 Edge launched with TouchWiz and topped out at Android 8 (Oreo), which lacks support for modern apps and security updates. In contrast, the Galaxy A42 5G runs One UI 5 based on Android 13, offering modern features, better privacy, and long-term support. Therefore, the A42 5G is better suited for users who rely on the latest apps and smoother user interfaces. The difference in software longevity and interface fluidity is significant here.
Build Quality & Design – Glass Curve vs Modern Simplicity
The Galaxy S7 Edge has a glass-and-metal curved body, offering a premium and ergonomic feel. It’s sleek, stylish, and compact. On the other hand, the A42 5G has a plastic back with a matte finish and geometric patterns, giving it a modern and minimal look. While the S7 Edge wins in build quality and feel, the A42 5G is more durable and easier to grip, especially for everyday users.
Connectivity – 5G vs Legacy LTE
When it comes to connectivity, the Galaxy S7 Edge supports 4G LTE, Wi-Fi 802.11ac, and Bluetooth 4.2, which are now considered outdated. The Galaxy A42 5G includes 5G support, Wi-Fi 5, Bluetooth 5.0, and USB Type-C, making it more compatible with modern networks and accessories. For future-proof use, A42 5G outperforms the older S7 Edge.
Exclusive Features – Edge Display vs 5G Power
The Galaxy S7 Edge introduced the Edge Panel, offering quick access to contacts, apps, and tools from the screen’s edge — a novelty that still feels unique. The Galaxy A42 5G, however, boasts 5G connectivity, longer battery life, and multi-camera support, features more aligned with current mobile trends. In short, while the S7 Edge had innovation in design, the A42 5G delivers practical, future-ready features.
Pricing – Nostalgia vs Modern Value
The Galaxy S7 Edge, though no longer in production, can be found refurbished at a very low price. It’s a budget choice for basic tasks or collectors. The Galaxy A42 5G, while also affordable (typically under $300), offers modern specs, 5G, and longer support. For the average user in 2025, the A42 5G presents significantly better value.
Final Verdict – Which One Deserves Your Pocket in 2025?
The choice between the Samsung Galaxy S7 Edge and the Samsung Galaxy A42 5G depends on your needs, budget, and expectations. If you want a beautifully designed phone with a curved display and don’t mind using it for basic functions, the S7 Edge is still a joy to use. However, if you prefer modern features, 5G connectivity, a larger battery, and ongoing software support, the Galaxy A42 5G is the more practical choice. Both devices offer great things in their own ways, but for most users in 2025, the Galaxy A42 5G is the smarter buy.
