Galaxy S21 FE 5G vs Galaxy Z Fold6

The Samsung Galaxy S21 FE 5G, released in January 2022, offers a traditional smartphone experience with flagship-level features. In contrast, the Samsung Galaxy Z Fold6, launched in July 2024, represents a significant evolution in mobile technology, featuring a foldable design that transforms a compact device into a larger tablet-like display. These two devices cater to different user preferences, with the S21 FE providing a conventional form factor and the Z Fold6 offering enhanced screen real estate and multitasking capabilities.

When considering the long-term usability of these devices, their release timelines and software support policies are key differentiators.

• Release and Software Support: The Galaxy S21 FE 5G, released in January 2022, launched with Android 12 and is expected to receive four major Android OS upgrades, with Android 16 being its last, and five years of security updates, extending into early 2027. The Galaxy Z Fold6, released in July 2024 with Android 14, benefits from Samsung's extended support policy, promising seven years of Android OS upgrades and security updates, potentially receiving updates until Android 21.
• Physical Durability and Repairability: The S21 FE features a metal frame with a plastic back and an IP68 rating for dust and water resistance. Its repairability is considered relatively good, with many components secured by screws, though the battery is tightly glued. The Z Fold6, while featuring a refined hinge and Gorilla Glass Victus 3 on its cover screen, has an IP48 rating, indicating protection against water but only limited dust ingress. Its complex foldable design results in an average repairability score for foldables, with delicate internal components and a challenging hinge repair process.
• Practical Lifespan: Users prioritizing extended software longevity will find the Z Fold6's seven-year update commitment appealing, ensuring access to the latest features and security patches for a longer period. The S21 FE offers a solid, though shorter, support window. The Z Fold6's hinge is tested for at least 200,000 folds, suggesting a robust mechanical lifespan for typical usage.

The performance of both devices is driven by their respective processors, influencing how smoothly they handle daily tasks and demanding applications.

• Processing Power: The Galaxy S21 FE 5G is equipped with a processor that delivers flagship-grade performance for its generation, handling everyday applications and multitasking with responsiveness.

• Resolution and Clarity: The S21 FE provides a 2340 x 1080 pixel resolution, resulting in sharp and clear visuals for typical smartphone usage. The Z Fold6's main display boasts a 2160 x 1856 pixel resolution, offering a highly detailed and immersive viewing area, while its cover screen also provides a crisp experience.
• Brightness and Smoothness: Both devices feature a 120Hz adaptive refresh rate, ensuring smooth scrolling and responsive interactions. The Z Fold6's main display can reach a peak brightness of up to 2,600 nits, providing excellent visibility even in bright outdoor conditions. The S21 FE also offers satisfying levels of brightness for various environments.

Both smartphones offer capable camera systems, though they are designed with different priorities and user experiences in mind.

• Rear Camera Systems: The Galaxy S21 FE 5G includes a versatile triple rear camera setup: a 12 MP wide lens with optical image stabilization (OIS), an 8 MP telephoto lens with 3x optical zoom and OIS, and a 12 MP ultrawide lens. The Galaxy Z Fold6 also features a triple rear camera system, comprising a 50 MP wide lens with Dual Pixel autofocus and OIS, a 12 MP ultrawide lens with a 123° field of view, and a 10 MP telephoto lens with 3x optical zoom and OIS.
• Photography Performance: The S21 FE is noted for good still photography and video recording, with its selfie camera also performing well. The Z Fold6's camera system is described as very solid, excelling in bright conditions and performing well in darker environments due to improved processing. It also incorporates a ProVisual Engine for AI-based image enhancements.
• Front Cameras and Video: The S21 FE has a 32 MP front camera. The Z Fold6 features a 10 MP front-facing camera on its cover screen and a 4 MP under-display camera on the main foldable screen, primarily for video calls and facial recognition.
