Ulefone RugKing

The Ulefone RugKing is built with a rugged form factor, carrying an IP68 ingress protection rating that covers submersion in water to a depth of 2 metres. It is not a folding device, and its physical footprint comes in at 173.4 mm tall, 83.4 mm wide, and 18.3 mm thick, with a total volume of approximately 264.65 cm³. The handset weighs 397 g, which is consistent with the reinforced construction associated with ruggedised smartphones.

The RugKing uses a 5.99″ IPS LCD touchscreen with a resolution of 720 x 1440 px, translating to a pixel density of 269 ppi, and operates at a standard refresh rate of 60Hz. The display is protected by Gorilla Glass 3, adding a layer of scratch and impact resistance. It does not support HDR10, HDR10+, or Dolby Vision, and there is no Always-On Display mode or secondary screen.

The RugKing is powered by the Unisoc T7255 chipset, fabricated on a 12 nm process and configured with eight threads using big.LITTLE technology — two cores running at 2 GHz and six at 1.8 GHz. It is paired with 8GB of DDR4 RAM at 1866 MHz, supports up to 14GB of maximum memory, and offers 256GB of internal storage via eMMC 5.1. Graphics are handled by an integrated Mali G57 MP1 GPU with a turbo frequency of 750 MHz, supporting OpenGL ES 3.2 and OpenCL 2.0. The SoC also integrates LTE, features ARM TrustZone security, and delivers a maximum memory bandwidth of 14.928 GB/s, with a 1 MB L3 cache rounding out the internal architecture. Geekbench 5 scores come in at 380 for single-core and 1391 for multi-core workloads.

The RugKing features a dual-lens rear camera system combining a 50 MP primary sensor and a 2 MP secondary lens, both using a CMOS sensor without back-side illumination. Autofocus options include phase-detection and touch autofocus, as well as continuous autofocus during video recording, though laser autofocus is not present. The main camera supports video recording at 1080p and 30 fps along with slow-motion capture, but does not offer optical zoom, HDR10 recording, Dolby Vision recording, or RAW output. Manual controls cover exposure, ISO, focus, and white balance, while burst mode and in-camera panorama are also available. A single LED flash is fitted at the rear — not dual-tone or RGB — and there is no front-facing flash. The 8 MP front camera has an aperture of f/2 and is a single-lens unit positioned conventionally, not under the display.

The RugKing runs Android 15, an open-source platform that supports multi-user accounts, split-screen multitasking, Picture-in-Picture, widgets, and app offloading. Privacy controls are fairly comprehensive, covering clipboard warnings, location access management, and camera and microphone permissions, though cross-site tracking blocking and Mail Privacy Protection are absent. Customisation options include dark mode, dynamic theming, and theme customisation, while notification controls and sharing intents allow further personalisation of the experience. The OS supports on-device machine learning, offline voice recognition, voice commands, and device tracking, and users can take full-page scrolling screenshots and use a media picker for selective file sharing. A child lock, battery health check, extra dim mode, and the ability to play games while they download add to everyday usability. Wi-Fi password sharing, focus modes, Quick Start, and desktop PC mode are not available, and OS updates are not delivered directly from the platform vendor.

The RugKing is equipped with a 9600 mAh rechargeable battery that supports 18W fast charging, and a charger is included in the box. A battery level indicator is present, giving users a clear readout of remaining charge. The battery is not removable, and neither wireless charging nor reverse wireless charging is supported.

The RugKing includes a 3.5 mm headphone jack and a built-in FM radio, offering a couple of useful audio conveniences. It does not have stereo speakers, and none of the advanced Bluetooth audio codecs — aptX, aptX HD, aptX Adaptive, aptX Lossless, or LDAC — are supported.

The RugKing supports dual SIM cards and connects via Wi-Fi 4 (802.11n) and Wi-Fi 5 (802.11ac), Bluetooth 5.0, and NFC, though 5G is not available. The USB Type-C port runs on USB 2.0, and there is no HDMI output. Download speeds reach up to 300 Mbit/s with uploads up to 100 Mbit/s, and an external memory slot allows for storage expansion. Location is handled through GPS with Galileo support, and onboard sensors include a gyroscope, accelerometer, and compass, while a barometer, infrared sensor, and heart rate monitor are absent. A fingerprint scanner is present for biometric authentication, but 3D facial recognition and iris scanning are not supported. ANT+, DLNA certification, satellite SOS, crash detection, motion and optical tracking, and a built-in projector are likewise not featured, and no stylus is included.

The RugKing includes a video light, which can be used as a torch during video recording. The display is flat rather than curved, and neither sapphire glass nor an e-paper panel is used.
