Design
The Ulefone Armor 28 Ultra is built for extreme conditions and hostile environments, hence its ultra-rugged body. The casing is hardened, machined, contoured, and reinforced for added durability. It is constructed using high-quality polycarbonate and reinforced metal, contributing to its solid, hefty feel.
The corners are outfitted with rubber bumpers to absorb impacts and safeguard the internal components, making it well-suited for drops and rough handling. Also, the rubberized port coverings for the USB-C charging and audio jack are a snug fit, firmly closing to protect the phone from dust or water, especially when used in extreme environments.
The Armor 28 Ultra features dimensions of 174.2 x 83.6 x 19.4 mm and weighs 450 grams. While it’s heavier than most smartphones, this added weight offers a sense of sturdiness and durability, making it an ideal choice for outdoor and rugged use in demanding professions like construction.
The front of the device is dominated by a 6.67-inch display with thick bezels surrounding the screen. Meanwhile, the display is protected by a high-strength Gorilla Glass screen that resists scratches, cracks, and impacts.
Flipping the device over reveals a robust camera array that takes center stage. The large, protruding camera module dominates the upper section of the rear panel. Within this square-shaped module, you’ll find a 1.04-inch secondary display, encircled by the triple rear camera setup and four LED flash units, creating a design reminiscent of a clock.
Meanwhile, the Armor 28 Ultra functionality extends beyond mere durability; it features an IP68/IP69K rating for water and dust resistance and meets MIL-STD-810H military standards for shock, vibration, and extreme temperatures. This makes it a reliable companion in extreme conditions.
On the left-hand side of the device, as you face the screen, you’ll find the TF SIM card slot, supporting dual SIMs and a microSD card for additional storage. Next to it is a customizable button, anodized in orange, which can be programmed for functions like SOS. Below that is the U-Smart connector, allowing you to attach a variety of accessories, such as an endoscope or microscope, for enhanced functionality.
On the right-hand side, there’s another anodized orange button, specifically designed to activate the camera and serve as the shutter button. Above it, you’ll find the power button with built-in fingerprint recognition, as well as the volume up and down buttons.
At the bottom of the Android phone, you’ll find a USB Type-C connector, which needs to be sealed with a small rubber bung to maintain its watertight integrity when the phone is submerged underwater. Finally, on top of the phone, there’s yet another small rubber bung, which, when removed, reveals the standard 3.5mm headphone jack.
The Ulefone Armor 28 Ultra impresses with its dual-screen design, offering both functionality and style. On the front, it boasts a large 6.67-inch 120Hz AMOLED display, delivering vibrant colors and fluid motion with a resolution of 1080 x 2400 pixels.
This display boasts a peak brightness of 2200 nits; hence, this screen remains clear even in direct sunlight, and the 120Hz refresh rate makes for a smooth, responsive experience. This ensures a smooth, fluid experience whether you’re scrolling through content, navigating apps, or playing games.
Additionally, this display features a high touch sensitivity that allows it to be used with gloves or wet hands, a particularly useful feature in industrial and outdoor settings. This ensures that the device remains functional and easy to operate in all conditions, enhancing its practicality. It also offers brilliant 1B color support, ensuring rich and deep hues.
To top it off, the display is protected by Corning Gorilla Glass Victus, known for its durability and fingerprint resistance, ensuring your screen stays clean and scratch-free even in the toughest environments.
On the back, there’s a 1.04-inch AMOLED secondary display that adds significant value. This smaller screen, though compact, is highly functional, featuring a resolution of 340 x 340 pixels. Despite its size, it provides clear and sharp visuals, making it perfect for checking notifications, viewing the time, or controlling music with ease. The crisp resolution ensures that even small details are easy to read at a glance.
It also has a peak brightness of 600 nits, ensuring that your notifications, time, and quick actions are always visible. Furthermore, this second display is not just a simple display either; it offers practical features like quick music control, making it an incredibly thoughtful addition. Similar to the front display, this display is also protected by Corning Gorilla Glass Victus, adding another layer of toughness to the already rugged phone.
Whether you’re in construction, hiking, or any other outdoor profession, the Armor 28 Ultra’s dual-display system ensures you have a rugged yet functional device that keeps you connected and productive in any condition.
Camera
The Ulefone Armor 28 Ultra’s camera setup is designed to deliver exceptional performance even in the most demanding environments. It sports a triple rear consisting of the 50MP main, 64MP night vision with a 50MP ultrawide, and a single 50MP front camera.
The main camera features a 50MP Sony IMX898 sensor, which stands out with its large 1-inch optical format, making it significantly more capable in low-light conditions compared to smaller sensors. The size of the sensor allows for larger individual pixels (1.6µm), which capture more light, providing better image quality in dim or challenging lighting. This sensor is paired with an 8-element lens with an f/1.9 aperture and an 85.1° field of view, ensuring sharp and vibrant shots.
Despite its 50MP resolution, the larger sensor ensures that each pixel is optimized for clarity, resulting in photos that are detailed and well-balanced across various lighting conditions. The Armor 28 Ultra can shoot stunning 12MP photos by default, with a level of detail that rivals even some premium smartphones.
Additionally, the 5G phone supports 8K video recording at 30fps, offering cinematic-quality footage, alongside 4K video at 30/60fps and 1080p video at 30/60fps. With the addition of gyro-EIS (Electronic Image Stabilization), videos are incredibly smooth and free of unwanted shakes, making it ideal for those on the move or working in rough environments.
The second camera is a 64MP Night Vision unit, powered by an OmniVision OV64B1B sensor. This sensor is equipped with an f/1.8 aperture, a 79.4° field of view, and four infrared (IR) LEDs, which give the camera the ability to capture detailed images in complete darkness.
Ulefone’s NightElf Ultra 3.0 algorithm further enhances the low-light performance, minimizing interference and capturing clear, detailed, and noise-free images in even the most challenging conditions.
The IR LEDs allow the camera to capture infrared images, which, while monochrome, retain exceptional detail and clarity, making this a standout feature for users who need to see in the dark, such as those working in security, emergency services, or outdoor activities. The camera records in 4K, ensuring high-quality video, even in low-light environments.
The third camera on the back is a 50MP ultra-wide and macro camera, utilizing the Samsung S5KJN1 ISOCELL sensor with an f/2.2 aperture and a 117.3° field of view. This ultra-wide sensor allows for expansive landscape shots with impressive detail, making it perfect for capturing sweeping vistas or large group photos. With its wide-angle capability, it excels at capturing more of the scene, providing users with greater creative freedom in their photography.
Also, the pixel size of 0.64µm helps enhance the image quality by ensuring each pixel can gather enough light, which is especially beneficial in low-light situations. It is also ideal for macro shots, enabling you to focus on small objects with excellent clarity and sharpness, making it versatile for both wide-angle shots and close-ups.
The front-facing camera is a 50MP wide-angle sensor, perfect for selfies or video calls. With its large sensor size, it delivers clear, detailed self-portraits, even in various lighting conditions. The 50MP resolution ensures that your selfies are vibrant and sharp, while the wide-angle lens makes it easy to fit more people into your frame, a great feature for group selfies or video conferencing.
The camera app is easy to use and packed with features. The interface is simple, with most settings readily accessible. The app features a large shutter button in the center of the screen, with quick access to Google Lens on the right, camera switch on the left, and shortcuts to AI tools and your gallery.
The camera also comes with different shooting modes, allowing you to switch between Night Vision, Beauty mode, 50MP mode, and More.” The app also offers intuitive toggles for common settings like HDR, flash, and scene recognition, while additional settings can be accessed through a simple overlay.
