Samsung Galaxy Z Fold 4 review: A high-performance evolution in foldable technology

Samsung has solidified its dominance in the foldable market with the release of the Galaxy Z Fold 4, a device that balances incremental hardware updates with significant software refinements. Although it retains the premium price point of over $2,000, the handset represents the pinnacle of the series to date. It caters specifically to power users and mobile gamers seeking a tablet-like experience in a pocketable, albeit substantial, form factor. While the high cost and the unique nature of a folding screen may cause hesitation for newcomers, this latest iteration aims to prove that the technology has matured beyond its experimental roots.

The physical presence of the device is formidable, even as Samsung has managed to make it thinner and lighter than its predecessor, the Z Fold 3. Weighing in at 263 grams, the handset possesses a robust profile that users have likened to a "brick," a sensation that is particularly noticeable when the device is folded in a pocket. The exterior features a 6.2-inch AMOLED cover display with a 2,316 x 904 resolution, while the internal 7.6-inch main screen offers a 2,176 x 1,812 resolution. Both panels support an adaptive 120Hz refresh rate, ensuring fluid motion and high responsiveness across all applications.

Performance is driven by the Snapdragon 8 Plus Gen 1 chipset, which facilitates nearly instantaneous app loading and smooth multitasking. For many users, the primary concern regarding the Fold series remains the central display crease. In this generation, Samsung has successfully reduced the visibility of the indentation, though it remains a tactile element that can be felt when sliding a finger across the screen. Despite being a potential deterrent for purists, the crease is largely invisible during active use, particularly on lighter backgrounds or when viewed from a direct angle, rarely distracting from the overall media experience.

The software environment, powered by Android 12L, transforms the Z Fold 4 into a formidable productivity tool. The integration of a taskbar and the ability to manage three simultaneous windows allows for a workflow that rivals small laptops or tablets. Native Samsung applications and optimized third-party platforms like Facebook utilize the expansive screen real estate effectively, though some apps like Instagram still lack full optimization. The device also excels in photography utility, allowing users to leverage the rear cameras for high-quality selfies while utilizing the folding hinge to steady the phone for video recording.

Mobile gaming serves as a primary showcase for the device's hardware capabilities. The combination of the massive internal display, the powerful SoC, and a peak brightness of 1,200 nits makes the Z Fold 4 an elite platform for high-fidelity titles. Testing with demanding games such as Warhammer 40,000: Tacticus and Diablo Immortal reveals that the device can maintain high frame rates at maximum graphical settings even in bright outdoor conditions. The immersive audio and expansive view offer a significant departure from traditional smartphone gaming, bridging the gap between mobile and console-quality experiences.

Durability and portability remain the final hurdles for widespread adoption. The "Armor Aluminum" frame provides a premium feel but is notably slippery, necessitating the use of a protective case which further increases the device’s bulk. However, for professionals who require the ability to edit documents, manage spreadsheets, and conduct video calls on the move, the trade-off in weight is often justified by the sheer utility of the 5G-connected foldable. While the Z Fold 4 may not entirely replace a dedicated laptop, it represents the closest the industry has come to a truly converged mobile computing device.
