Ulefone Armor Mini 20 Pro

The Ulefone Armor Mini 20 Pro features a rugged, non-folding build rated IP68 for full waterproof protection, making it suited for use in wet or harsh environments. It measures 133.5 × 63.3 × 24.9 mm with a thickness of 24.9 mm and a total volume of approximately 210.42 cm³, while tipping the scales at 301 g. Repairability is a notable aspect of its design, as it holds a French Repairability Index score of 9.6, indicating strong serviceability credentials.

The device uses an IPS LCD touchscreen measuring 4.7 inches, with a resolution of 720 × 1600 px and a pixel density of 373 ppi. It supports a 90 Hz refresh rate, contributing to smoother on-screen motion during scrolling and general use. The display does not include branded damage-resistant glass, HDR10, HDR10+, Dolby Vision, or an Always-On Display mode, and there is no secondary screen present.

The device is powered by the MediaTek Dimensity 6300 chipset, built on a 6 nm process with an 8-thread CPU running at 2 × 2.4 GHz and 6 × 2 GHz using big.LITTLE architecture with HMP support. It pairs 8 GB of DDR4 RAM running at 2133 MHz — with a maximum supported memory amount of 12 GB — alongside 256 GB of internal storage, while the memory subsystem offers a maximum bandwidth of 17.07 GB/s. The Arm Mali-G57 MC2 GPU operates at 950 MHz, supports DirectX 12, and is backed by integrated graphics. Cache configuration consists of 512 KB L1, 1 MB L2, and 2 MB L3, and the chipset also integrates LTE. Benchmark results stand at 782 for single-core and 2012 for multi-core in Geekbench 6, with the platform further supporting 64-bit processing and multithreading.

The main camera features a 50 MP single-lens CMOS sensor with 1.2 µm pixel size and an f/2.0 aperture, capable of recording video at 1440 × 30 fps. It supports phase-detection autofocus for stills, continuous autofocus during video, and touch autofocus, though laser autofocus is not present. Manual controls cover exposure, ISO, focus, and white balance, while shutter speed adjustment is not available. Additional shooting modes include HDR, burst, slow-motion, timelapse, and in-camera panorama, though 360° panorama, RAW capture, HDR10 recording, Dolby Vision recording, and 3D recording are not supported. Lighting is handled by a dual-tone LED flash with two LEDs; there is no RGB flash. The front camera offers 32 MP at f/2.5 and is a single-lens unit positioned conventionally — not under the display — and has no front-facing flash. Optical zoom is not available, and the main sensor does not use back-side illumination.

The device runs Android 14 and includes a broad set of privacy controls, covering clipboard warnings, location privacy options, camera and microphone access management, and the ability to block app tracking, though cross-site tracking blocking and Mail Privacy Protection are not available. Customization options span theme customization, dynamic theming, dark mode, and an extra dim mode, while focus modes and app offloading are not supported. Notification handling is flexible, with notification permissions, customizable notifications, and a media picker all present, and the system also supports widgets, sharing intents, split-screen multitasking, Picture-in-Picture, full-page screenshots, Live Text, and the ability to play games while they download. On-device machine learning is included alongside offline voice recognition, voice commands, phone tracking, multi-user support, and a child lock. Battery health check is available, but Wi-Fi password sharing, Quick Start, and the ability to use the device as a PC are not. Direct OS updates from the vendor are not provided, and the platform is free and open source.

The device houses a 6200 mAh rechargeable battery with a built-in level indicator, and a charger is included in the box. Wired fast charging is supported at 33W, while wireless charging runs at 15W, and reverse wireless charging is also available at 5W. The battery is not removable.

The device includes a 3.5 mm headphone jack and a built-in radio, but does not feature stereo speakers. On the wireless audio side, none of the advanced Bluetooth codecs — aptX, aptX HD, aptX Adaptive, aptX Lossless, or LDAC — are supported.

The device supports 5G connectivity with a maximum download speed of 3300 Mbit/s and accommodates two SIM cards alongside an external memory slot. Wireless networking covers Wi-Fi 4 (802.11n) and Wi-Fi 5 (802.11ac), while Bluetooth 5.2 and NFC round out the short-range options. The USB Type-C port operates at USB 2.0 speed, and there is no HDMI output. Sensor coverage is broad, including a gyroscope, accelerometer, compass, barometer, GPS with Galileo support, and an infrared sensor, though there is no heart rate monitor, ANT+ support, motion tracking, or optical tracking. Biometric security is handled by a fingerprint scanner; 3D facial recognition and an iris scanner are not available. Crash detection, emergency SOS via satellite, DLNA certification, a built-in projector, and a stylus are all absent.

The device includes a video light for illumination during video recording. The display is flat rather than curved, uses neither sapphire glass nor e-paper technology.
