In this comprehensive article by Academic Block, we will delve into every aspect of the Galaxy Z Fold 1, exploring its design, display, performance, camera capabilities, software features, and overall user experience.

Design and Build

The first impression of any smartphone is often formed by its design, and the Galaxy Z Fold 1 leaves a lasting one. Constructed with a combination of glass and metal, the device exudes a premium feel. When folded, it resembles a conventional smartphone with a 6.23-inch cover display, providing quick access to notifications and basic functionalities without having to unfold the device.

Upon opening the device, users are greeted by the impressive 7.3-inch Infinity Flex Display, which seamlessly unfolds to reveal a tablet-like experience. The hinge mechanism, a critical component of any foldable phone, is robust and has undergone extensive testing to ensure durability. The device opens and closes smoothly, and the hinge can be stopped at various angles, allowing users to position the screen at their preferred viewing angle.


The highlight of the Galaxy Z Fold 1 is undoubtedly its foldable display. The 7.3-inch Infinity Flex Display is a Dynamic AMOLED panel with a resolution of 2152 x 1536 pixels. The high resolution, combined with HDR10+ support, delivers vibrant colors and deep blacks, making multimedia consumption a visually immersive experience. The foldable nature of the display introduces a new dimension to multitasking, enabling users to run three apps simultaneously on the larger screen.

The cover display, though smaller at 6.23 inches, boasts a Super AMOLED panel with a resolution of 2260 x 816 pixels. This display serves well for quick tasks, such as checking messages or answering calls, without the need to unfold the device.


Under the hood, the Galaxy Z Fold 1 is powered by the Qualcomm Snapdragon 855 processor, coupled with 12GB of RAM. While this might not be the latest chipset available at the time of its release, the device still delivers a smooth and responsive performance. Multitasking is a breeze, thanks to the ample amount of RAM, and the Adreno 640 GPU ensures that graphics-intensive applications and games run seamlessly.

The 512GB of internal storage provides ample space for users to store their multimedia files, apps, and documents. However, the absence of expandable storage might be a drawback for users who require even more space.

Camera Capabilities

Samsung has always been a trailblazer in smartphone camera technology, and the Galaxy Z Fold 1 is no exception. The device features a versatile triple-camera setup on the rear, consisting of a 12MP wide-angle lens, a 12MP ultrawide lens, and a 12MP telephoto lens. The cameras deliver impressive image quality with accurate colors, sharp details, and excellent dynamic range.

The foldable design of the phone opens up new possibilities for photography. Users can utilize the larger unfolded display as a viewfinder, providing a more immersive and precise framing experience. Additionally, the front cover display enables users to take high-quality selfies using the rear cameras, eliminating the need for a dedicated front-facing camera.

Software Features

The Galaxy Z Fold 1 runs on Samsung’s One UI, based on Android 9.0 Pie. The software is optimized to take full advantage of the foldable form factor, offering a seamless transition between the cover display and the unfolded screen. The Multi-Active Window feature allows users to run multiple applications simultaneously, enhancing productivity and multitasking capabilities.

Samsung has also introduced App Continuity, a feature that enables apps to seamlessly transition from the cover display to the main display when the device is unfolded. This ensures a consistent and uninterrupted user experience, making the most of the foldable design.

User Experience

The user experience on the Galaxy Z Fold 1 is a unique blend of the familiarity of a traditional smartphone and the versatility of a tablet. The cover display provides a compact and convenient way to interact with the device for quick tasks, while the unfolded display offers a larger canvas for immersive content consumption, productivity, and gaming.

The hinge mechanism, despite being a point of concern for durability, has undergone rigorous testing and holds up well under normal usage. The device feels solid in the hand, and the build quality instills confidence in its long-term durability.

Battery Life

Powering the Galaxy Z Fold 1 is a dual-battery system with a combined capacity of 4,380mAh. While the battery capacity might seem modest, the optimization of the hardware and software ensures a respectable battery life. The device easily lasts a full day with moderate to heavy usage, and the inclusion of fast charging support provides a quick top-up when needed.

Final Words

The Samsung Galaxy Z Fold 1 represents a bold step into the future of smartphone design and functionality. With its foldable display, premium build quality, impressive camera capabilities, and innovative software features, it offers a unique user experience that sets it apart from conventional smartphones. While the device may not be without its limitations, such as the reliance on an older processor and the high price point, it remains a groundbreaking device that showcases Samsung’s commitment to pushing the boundaries of mobile technology.
