Galaxy Z Flip6 • Unlocked vs Galaxy Z Fold4 • Unlocked

The Samsung Galaxy Z Flip6, released in July 2024, and the Samsung Galaxy Z Fold4, launched in August 2022, represent distinct approaches to foldable smartphone design. While both devices offer the innovative flexibility of a folding screen, they cater to different user needs through their unique form factors and feature sets. The Z Flip6 emphasizes a compact, pocketable experience, whereas the Z Fold4 prioritizes a larger, tablet-like display for enhanced productivity and media consumption. Both operate on the Android platform with Samsung's One UI, offering a consistent software experience.

When considering the long-term usability of these foldable devices, their release timelines and software support policies are key differentiators. The newer Galaxy Z Flip6 benefits from a significantly extended support period, while the Galaxy Z Fold4, being an earlier model, has a shorter remaining update window.

• Release Timeline and Software Support: The Galaxy Z Flip6, released in 2024, is promised seven years of Android OS upgrades and security updates, extending its software longevity until approximately 2031. In contrast, the Galaxy Z Fold4, from 2022, was guaranteed four major Android OS upgrades (up to Android 16) and five years of security updates, with its support ending around 2027.
• Physical Durability: Both devices feature robust construction for foldables. The Galaxy Z Flip6 incorporates an enhanced armored aluminum frame and boasts an IP48 rating for water and dust resistance, a notable improvement over its predecessor. The Galaxy Z Fold4 carries an IPX8 water resistance rating, meaning it can withstand submersion but does not have official dust resistance. Both models utilize Gorilla Glass Victus or Victus 2 on their outer displays for scratch protection, while their inner foldable screens, protected by Ultra-Thin Glass and a plastic layer, show scratches at a lower Mohs hardness level.
• Expected Practical Lifespan: Users can expect the Galaxy Z Flip6 to remain current with software features and security patches for a considerably longer period due to its extended support. Both devices are designed to withstand numerous folds, with the Z Fold4 certified for 200,000 folds, suggesting a practical lifespan of several years under typical usage.

The performance capabilities of the Galaxy Z Flip6 and Galaxy Z Fold4 reflect their respective generations of mobile technology. While both offer smooth operation for daily tasks, the newer Flip6 integrates a more advanced processing unit.

• Processor Capabilities: The Galaxy Z Flip6 is equipped with a current-generation processor, enabling it to handle demanding applications and multitasking with notable responsiveness. The Galaxy Z Fold4 features a powerful processor from its release year, which still provides a fluid experience for most applications and gaming.
• Multitasking and Responsiveness: Both devices offer ample RAM, with the Z Flip6 featuring 12 GB and the Z Fold4 also including 12 GB, ensuring efficient app switching and background process management. The Z Flip6 benefits from a dedicated vapor chamber cooling system, which helps maintain sustained performance during intensive tasks like extended gaming sessions.
• Storage Options: The Galaxy Z Flip6 is available with 256 GB or 512 GB of internal storage, utilizing faster UFS 4.0 technology. The Galaxy Z Fold4 offers more storage flexibility, with options for 256 GB, 512 GB, or 1 TB of UFS 3.1 storage. Neither device supports expandable storage via microSD cards.

The display experience is a primary differentiator between these two foldable smartphones, with each offering a distinct approach to screen size and utility.

• Display Technology and Size: The Galaxy Z Flip6 features a 6.7-inch Dynamic AMOLED 2X main display when unfolded, providing a traditional smartphone screen experience. The Galaxy Z Fold4, in contrast, unfolds to reveal a much larger 7.6-inch Dynamic AMOLED 2X main display, offering a tablet-like canvas for productivity and media. Both main displays support a variable refresh rate up to 120 Hz for smooth scrolling and responsiveness.
• Resolution and Clarity: The Z Flip6's main display has a resolution of 2640 x 1080 pixels, resulting in a pixel density of approximately 426 PPI. The Z Fold4's larger main display offers a resolution of 2176 x 1812 pixels, with a pixel density of around 374 PPI. Both provide clear and vibrant visuals for typical viewing distances.
• Cover Displays and Brightness: The Galaxy Z Flip6 includes a 3.4-inch Super AMOLED cover display for quick interactions and notifications. The Galaxy Z Fold4 features a larger and more functional 6.2-inch Dynamic AMOLED 2X cover display, which can be used for a wider range of tasks without unfolding the device. The Z Flip6's main display can reach a peak brightness of 2600 nits, enhancing outdoor visibility. The Z Fold4's displays also offer good brightness for various lighting conditions.

The camera systems on both the Galaxy Z Flip6 and Galaxy Z Fold4 are designed to capture quality images, though they differ in their versatility and specific strengths.

• Rear Camera Systems: The Galaxy Z Flip6 features a dual-camera setup with a 50 MP wide-angle main sensor and a 12 MP ultra-wide-angle lens. The 50 MP main sensor is an improvement over its predecessor, offering good dynamic range and accurate exposure in daylight. The Galaxy Z Fold4 boasts a triple-camera system, including a 50 MP wide-angle main sensor, a 12 MP ultra-wide-angle lens, and a 10 MP telephoto lens with 3x optical zoom and up to 30x digital zoom. This dedicated telephoto lens provides greater flexibility for zoomed-in shots.
• Photography Performance: Both devices deliver vibrant colors and clear details in well-lit conditions. The Z Flip6's main camera performs well for everyday photography, though some users note inconsistencies in portrait mode and struggles with low-light noise. The Z Fold4's camera system, borrowing from the Galaxy S22 line, offers strong performance across its lenses, with good clarity even in night shots.
• Video Recording and Selfie Cameras: Both phones are capable of high-quality video recording, with the Z Flip6's main sensor producing sharp 4K videos at up to 60fps and the Z Fold4 capable of 8K video at 24fps from its main camera.
