Galaxy Z Fold4 • Unlocked vs Galaxy Z Fold6 • Unlocked

The Samsung Galaxy Z Fold4, released in August 2022, and the Samsung Galaxy Z Fold6, launched in July 2024, represent different generations of Samsung's foldable smartphone line. Both devices operate on the Android platform, offering a tablet-like experience in a pocketable form factor. The Z Fold6 introduces refinements in design, an updated processor, and extended software support, building upon the foundation established by the Z Fold4.

The practical lifespan of a smartphone is significantly influenced by its release date and the manufacturer's commitment to software updates.

• Release Timeline: The Galaxy Z Fold4 was released in August 2022, while the Galaxy Z Fold6 followed in July 2024. This two-year difference means the Z Fold6 benefits from a more recent hardware and software foundation.
• Software Longevity: The Z Fold4 was promised four major Android OS updates and five years of security updates, extending its support until approximately August 2027. In contrast, the Z Fold6 benefits from Samsung's extended support policy, offering seven years of both OS upgrades and security updates, which means it will receive support until July 2031.
• Repairability: Both models feature an IPX8 water resistance rating, indicating protection against submersion in water, but neither offers official dust resistance due to the nature of their folding design. The Z Fold6 incorporates Gorilla Glass Armor on its cover screen, an advancement over the Gorilla Glass Victus+ found on the Z Fold4, potentially offering enhanced scratch resistance.

Performance in foldable smartphones is crucial for seamless multitasking and demanding applications across both displays.

• Processor Capabilities: The Galaxy Z Fold4 is equipped with a processor that handles everyday tasks and moderate multitasking efficiently. The Galaxy Z Fold6 features a newer generation processor, designed to deliver improved speed and efficiency, particularly noticeable in complex applications, advanced AI features, and graphic-intensive tasks.
• System Responsiveness: Users of the Z Fold4 generally experience smooth navigation and app loading. The Z Fold6 offers a more responsive experience, especially when switching between multiple applications or running several demanding programs simultaneously, due to its enhanced processing power.
• Multitasking Efficiency: Both devices come with 12GB of RAM, which is ample for managing numerous open applications. The Z Fold6's more efficient processor, combined with this RAM, allows for slightly smoother transitions and sustained performance during heavy multitasking sessions.

The display experience is a primary differentiator for foldable phones, impacting both usability and visual enjoyment.

• Display Technology and Clarity: Both the Galaxy Z Fold4 and Z Fold6 feature Dynamic AMOLED 2X displays for both their main and cover screens, providing vibrant colors and deep blacks. The Z Fold6's displays offer a slightly higher resolution on both screens, contributing to marginally sharper text and images.
• Brightness and Refresh Rate: Both models support an adaptive refresh rate of up to 120Hz on both displays, ensuring smooth scrolling and fluid animations while conserving battery life when static content is shown. The Z Fold6 boasts a higher peak brightness, making its screens more easily viewable in bright outdoor conditions.
• Screen Size and Aspect Ratio: The Z Fold4 features a 7.6-inch main display and a 6.2-inch cover display. The Z Fold6 maintains a 7.6-inch main display but introduces a slightly wider aspect ratio for both the main and cover screens, with the cover screen measuring 6.3 inches. This wider cover screen on the Z Fold6 aims to provide a more conventional smartphone feel when folded, enhancing one-handed usability.

The camera systems on both foldable devices are designed to offer versatile photography and videography options.

• Camera System Configuration: Both the Galaxy Z Fold4 and Z Fold6 feature a triple rear camera setup, consisting of a 50MP main sensor, a 12MP ultrawide lens, and a 10MP telephoto lens with 3x optical zoom. They also include a 10MP camera on the cover display and a 4MP under-display camera on the inner screen.
• Photography Performance: The Z Fold4 offers a capable camera system, delivering detailed and vibrant photos in good lighting conditions, with improved telephoto capabilities over its predecessor. While the Z Fold6 shares similar hardware specifications, it benefits from newer image processing algorithms and AI enhancements, which can lead to subtle improvements in color accuracy, dynamic range, and low-light performance.
• Video Recording and Features: Both devices are capable of recording high-resolution video. The Z Fold6's updated processor may offer more stable video recording and advanced computational photography features. Users can leverage the foldable form factor on both models to use the main cameras for high-quality selfies or video calls, utilizing the cover screen as a viewfinder.
