Galaxy Z Fold4 Vs Galaxy Z Fold7

The Samsung Galaxy Z Fold4 (released in August 2022) and the Samsung Galaxy Z Fold7 (released in July 2025) represent different generations of Samsung's foldable smartphone line. While both offer the unique book-style folding design, the Z Fold7 introduces significant advancements in durability, display technology, and internal performance, building upon the foundation laid by its predecessor. Both devices operate on the Android platform, offering a consistent software experience with Samsung's One UI.

The longevity of a foldable device is a key consideration, encompassing both physical resilience and software support. The Galaxy Z Fold7 marks a substantial leap in expected lifespan compared to the Z Fold4.

• Software Support: The Galaxy Z Fold4, launched with Android 12L, was eligible for four major Android OS updates and five years of security patches. In contrast, the Galaxy Z Fold7, shipping with Android 16, benefits from Samsung's extended policy, promising seven years of Android OS upgrades and security updates, extending its practical software lifespan significantly.
• Physical Durability: The Z Fold4 featured an IPX8 water resistance rating, but lacked official dust resistance. Its hinge was rated for approximately 200,000 folds. The Z Fold7 introduces an IP48 rating, adding a degree of dust protection, and boasts a redesigned Armor FlexHinge with dust-protective brushes. Its foldable display is rated for up to 500,000 folds, a 2.5x improvement, achieved through a 50% thicker Ultra Thin Glass and a new shock-resistant structure.
• Repairability: While specific repairability scores can vary, the Z Fold7's enhanced hinge and display construction aim to reduce common points of failure seen in earlier foldable generations, potentially leading to fewer hardware-related issues over its extended lifespan. Users of the Z Fold4 occasionally reported issues with the inner screen or hinge over time.

Performance is a critical aspect for devices designed for multitasking and demanding applications. The three-year gap between these models brings notable generational improvements in processing power and system responsiveness.

• Processing Power: The Galaxy Z Fold4 is powered by a capable processor that handles everyday tasks, demanding applications, and gaming smoothly. The Galaxy Z Fold7 features a newer, custom-tuned processor designed for Galaxy devices, offering a significant boost in raw performance. This translates to faster app loading, more fluid multitasking, and enhanced capabilities for intensive tasks like advanced gaming and on-device AI features.
• Multitasking and Responsiveness: Both devices are designed for efficient multitasking, leveraging their large internal displays. The Z Fold7's more advanced processor and potentially optimized software contribute to a more responsive overall user experience, especially when running multiple applications simultaneously or switching between them frequently.
• Storage and Memory: Both models offer 12GB of RAM in their standard configurations, with the Z Fold7 also providing a 16GB RAM option for its highest storage variant, which can benefit users who frequently engage in very heavy multitasking or run memory-intensive applications. Both come with various storage options, typically starting from 256GB.

The display experience is central to a foldable phone, and both the Z Fold4 and Z Fold7 offer expansive, high-quality screens, though the newer model brings refinements.

• Display Technology and Size: Both devices feature Dynamic AMOLED 2X displays for vibrant colors and deep blacks. The Z Fold4 has a 7.6-inch main foldable display and a 6.2-inch cover screen. The Z Fold7 expands on this with an 8.0-inch main display and a larger 6.5-inch cover screen, offering a more expansive viewing area.
• Resolution and Brightness: The Z Fold4's main display has a resolution of 2176 x 1812 pixels, while its cover screen is 2316 x 904 pixels. The Z Fold7 features a main display resolution of 2184 x 1968 pixels and a cover screen of 2520 x 1080 pixels, providing sharper visuals. The Z Fold7 also boasts a significantly higher peak brightness of 2,600 nits on both screens, compared to the Z Fold4's peak brightness, improving outdoor visibility.
• Refresh Rate and Aspect Ratio: Both models offer a 120Hz adaptive refresh rate on both their main and cover displays for smooth scrolling and responsive interactions. The Z Fold7's cover screen adopts a wider 21:9 aspect ratio, making it feel more like a traditional smartphone when folded, a notable change from the Z Fold4's narrower cover display.

Camera capabilities have seen substantial upgrades across generations of Samsung's foldable devices, with the Z Fold7 featuring a more advanced system.

• Rear Camera System: The Galaxy Z Fold4 features a triple rear camera setup with a 50MP main sensor, a 12MP ultrawide lens, and a 10MP telephoto lens with 3x optical zoom. The Galaxy Z Fold7 significantly upgrades the main sensor to 200MP with a wider aperture, alongside a 12MP ultrawide and a 10MP telephoto lens with 3x optical zoom. This higher resolution main sensor on the Z Fold7 allows for greater detail and flexibility in cropping.
• Low-Light and Video Performance: Both devices offer good low-light performance, with the Z Fold7 benefiting from its larger main sensor and advanced image processing (ProVisual Engine) for improved clarity and detail in challenging lighting conditions. Both can record video at up to 8K resolution at 24 frames per second.
• Front and Under-Display Cameras: The Z Fold4 includes a 10MP cover camera and a 4MP under-display camera (UDC) on the main screen, which is primarily suited for video calls. The Z Fold7 replaces the UDC with a 10MP hole-punch camera on the main display and retains a 10MP cover camera, offering more consistent selfie quality across both front-facing options.
