Our take on the Ulefone Armor X31 Pro 5G Rugged Smartphone (2025)

The Ulefone Armor X31 Pro 5G is a rugged Android 14 phone built around a MediaTek Dimensity 6300 chip with 8GB of RAM plus 8GB virtual RAM and 256GB of storage, expandable to 2TB via microSD. It stands out for its triple camera setup: a 64MP Sony IMX682 main sensor, a 25MP night vision camera and a 16MP front camera with an underwater mode. A 6050 mAh battery with 18W charging and reverse charging, a 120 lumen built-in flashlight and Google Lens support round it out. It suits outdoor workers, travelers and anyone who needs a tough phone with night vision and long standby rather than a slim flagship. Against mainstream rugged rivals it leans on the night vision camera and big battery, but the Dimensity 6300 is a mid-range chip and the body is heavy and bulky.
