Galaxy S21 FE 5G • Locked Verizon vs Galaxy Z Fold4 • Unlocked

The Samsung Galaxy S21 FE 5G (2022) and the Samsung Galaxy Z Fold4 (2022) represent distinct approaches to smartphone design and functionality. While both devices operate on the Android platform, the S21 FE offers a traditional smartphone experience, whereas the Z Fold4 introduces a foldable design that transforms from a compact phone into a larger tablet-like display. This comparison will explore their core differences to help users determine which device best suits their needs, considering quality-assured refurbished options as a sustainable choice.

When considering the long-term usability of these devices, several factors come into play, including their release timelines, software support, and physical resilience.

• Release Timeline: The Galaxy S21 FE 5G was released in January 2022, while the Galaxy Z Fold4 followed in August 2022. This seven-month difference means the Z Fold4 will likely receive software updates for a slightly longer period.
• Software Longevity: Both devices launched with Android 12, and Samsung typically provides several years of Android OS upgrades and security updates. The Galaxy Z Fold4 is expected to receive up to Android 16 and five years of security updates. Users can anticipate continued software support for both, with the Z Fold4 having a minor edge due to its later release.
• Physical Durability: The Galaxy S21 FE 5G features an IP68 rating for dust and water resistance, along with Gorilla Glass Victus protecting its display. The Galaxy Z Fold4, while water-resistant with an IPX8 rating, does not have a dust resistance rating. Its cover screen and back panel use Gorilla Glass Victus+, but the foldable inner display relies on Ultra Thin Glass, which users report is more susceptible to scratches than the outer display.

The performance of a smartphone is crucial for daily tasks, from navigating apps to demanding multimedia use and multitasking.

• Processing Power: The Galaxy S21 FE 5G, in its US variant, is equipped with a processor that handles everyday applications and moderate gaming smoothly. The Galaxy Z Fold4 features a newer generation processor, providing enhanced speed and efficiency for more intensive tasks, complex applications, and seamless transitions between multiple apps.
• Multitasking and Responsiveness: The Galaxy Z Fold4 comes with 12GB of RAM, allowing for robust multitasking and keeping numerous applications open without significant slowdowns. The S21 FE 5G typically offers 6GB or 8GB of RAM, which is sufficient for most users but may show limitations when handling a very high number of concurrent demanding applications.
• Storage Options: The S21 FE 5G is available with 128GB or 256GB of internal storage. The Z Fold4 offers more expansive storage options, including 256GB, 512GB, and up to 1TB, catering to users with larger digital libraries or extensive app usage. Neither device supports expandable storage via a microSD card.

The display is a primary interface for smartphone interaction, and both devices offer distinct visual experiences.

• Display Technology and Clarity: Both the Galaxy S21 FE 5G and the Galaxy Z Fold4 utilize Dynamic AMOLED 2X display technology, known for vibrant colors and deep blacks. The S21 FE 5G features a single 6.4-inch display with a resolution of 1080 x 2400 pixels. The Z Fold4 offers a dual-screen setup: a 6.2-inch cover display and a larger 7.6-inch foldable inner display when unfolded, both with high resolutions for sharp visuals.
• Refresh Rate and Smoothness: Both devices offer a 120Hz refresh rate, contributing to smoother scrolling and more fluid animations. This high refresh rate enhances the user experience during gaming and general navigation.
• Viewing Experience: The S21 FE 5G provides a traditional, flat screen experience. The Z Fold4's main display, when unfolded, offers a significantly larger canvas, suitable for immersive media consumption, detailed document viewing, and enhanced multitasking with multiple apps open simultaneously.

For many users, camera capabilities are a key differentiator, and both Samsung devices provide versatile photography and videography tools.

• Rear Camera Systems: The Galaxy S21 FE 5G features a triple-camera setup with a 12MP wide lens, a 12MP ultrawide lens, and an 8MP telephoto lens with 3x optical zoom. The Galaxy Z Fold4 also has a triple-camera system, but with a higher resolution 50MP main wide lens, a 12MP ultrawide, and a 10MP telephoto lens with 3x optical zoom.
• Photography Performance: The Z Fold4's larger main sensor contributes to improved low-light performance and captures more detail in various lighting conditions compared to the S21 FE 5G. Both devices offer features like optical image stabilization (OIS) for clearer photos and videos.
• Front-Facing Cameras and Video: The S21 FE 5G has a 32MP front camera. The Z Fold4 has a 10MP camera on its cover display and a 4MP under-display camera on the main screen, offering flexibility for selfies and video calls. Both phones are capable of recording high-resolution video.
