Ulefone Armor 28 Ultra

The Ulefone Armor 28 Ultra is built around a rugged, non-folding form factor designed to withstand harsh environments, backed by an IP68 waterproof rating that confirms full water resistance. It measures 174.2 mm tall, 83.6 mm wide, and 19.4 mm thick, with a total volume of approximately 282.52 cm³, reflecting the substantial build typical of reinforced handsets. At 450 g, the device carries considerable weight, which is consistent with its heavy-duty construction and durable materials.

The Armor 28 Ultra features a 6.67″ OLED/AMOLED touchscreen with a 1080 x 2400 px resolution and a pixel density of 395 ppi, delivering a sharp and vibrant visual experience. The display runs at a 120Hz refresh rate with a 480Hz touch sampling rate, and reaches a typical brightness of 900 nits, while HDR10 support is included though HDR10+ and Dolby Vision are not. It is protected by Gorilla Glass Victus and supports an Always-On Display mode. Alongside the main panel, the device includes a secondary touchscreen with a resolution of 340 x 340px.

The Armor 28 Ultra is driven by the Mediatek Dimensity 9300 Plus chipset, built on a 4 nm process with 22,700 million transistors and an 8-thread CPU configuration clocked at 1 x 3.4 GHz, 3 x 2.85 GHz, and 4 x 2 GHz using big.LITTLE architecture with HMP support, though simultaneous multithreading is not enabled. It is paired with 16 GB of LPDDR5 RAM running at 4800 MHz across two memory channels, with a maximum supported memory amount of 24 GB, a maximum bandwidth of 76.8 GB/s, an 8 MB L2 cache, and an 18 MB L3 cache. Graphics are handled by the integrated Arm Immortalis-G720 MC12 GPU at 1300 MHz, supporting DirectX 12, OpenGL ES 3.2, and OpenCL 2. The device offers 1024 GB of internal storage, integrated LTE, and 64-bit support, and posts an AnTuTu score of 2,300,000, a Geekbench 6 single-core result of 2302, and a multi-core result of 7547.

The Armor 28 Ultra carries a triple rear camera system with sensors at 64 MP, 50 MP, and 50 MP, paired with apertures of f/1.8, f/1.9, and f/2.2 respectively, all using CMOS sensors without back-illumination. The main camera supports phase-detection autofocus for stills, continuous autofocus during video, and touch autofocus, while laser autofocus is absent and optical image stabilization is not included. Manual controls extend to exposure, ISO, focus, and white balance, and the camera also offers burst mode and in-camera panoramas, though manual shutter speed, RAW capture, slow-motion recording, timelapse, 360° panorama, HDR10 recording, Dolby Vision recording, and 3D capture are not supported. Video recording reaches up to 4320 x 30 fps, and the flash system consists of four LEDs in a dual-tone configuration, with no RGB flash. The single front camera delivers 50 MP at f/2.5, without a front flash, a secondary lens, or an under-display placement.

The Armor 28 Ultra runs Android 14, a free and open-source platform that supports multi-user operation, voice commands, offline voice recognition, on-device machine learning, and phone tracking. On the privacy side, it offers clipboard warnings, location privacy options, camera and microphone access controls, and the ability to block app tracking, though Mail Privacy Protection and cross-site tracking blocking are absent. The interface supports dark mode, dynamic theming, theme customization, widgets, customizable notifications, notification permission controls, a media picker, Live Text, sharing intents, and an extra dim mode, while focus modes and app offloading are not available. Productivity features include split-screen multitasking, Picture-in-Picture, full-page screenshots, a child lock, battery health check, and the ability to play games while they are still downloading. Direct OS updates from the vendor are not supported, and Wi-Fi password sharing and Quick Start are also absent.

The Armor 28 Ultra houses a 10600 mAh rechargeable battery with a built-in level indicator, supporting wired fast charging at 120W and wireless charging at 50W. Reverse wireless charging is not available, and the battery is not removable.

The Armor 28 Ultra includes a 3.5 mm headphone jack and a built-in radio, while stereo speakers are not present. For wireless audio, it supports LDAC, though aptX, aptX HD, aptX Adaptive, and aptX Lossless are all absent.

The Armor 28 Ultra offers a broad connectivity suite, including 5G support, Wi-Fi 4, 5, 6, 6E, and 7, Bluetooth 5.4, NFC, and a USB Type-C port running at USB 3.2, with download speeds reaching 10,000 Mbits/s and upload speeds of 7,000 Mbits/s. It accommodates two SIM cards and includes an external memory slot. Location and sensing capabilities cover GPS with Galileo support, a compass, gyroscope, accelerometer, barometer, and infrared sensor, while a fingerprint scanner handles biometric authentication; 3D facial recognition, an iris scanner, and a heart rate monitor are not present. The device does not include HDMI output, a built-in projector, a stylus, ANT+ support, DLNA certification, motion or optical tracking, crash detection, or emergency SOS via satellite.

The Armor 28 Ultra includes a video light, while its display is flat rather than curved and uses neither sapphire glass nor an e-paper panel.
