ulefone designed this phone with durability in mind. The device measures 174.2 x 83.6 x 19.4 mm (approx. 6.86 x 3.29 x 0.76 inches) and weighs 450 grams (0.99 lb). This weight may seem more difficult than traditional smartphones, but it's a compromise between additional durability and a large battery. The phone has a Nano-Sim + Nano-SIM slot, certified with IP68/IP69K. This means it is dusty and waterproof (soaking up to 2 meters for 30 minutes can survive). Furthermore, it can withstand high pressure water jets. This contributes to its robustness.

The device is MIL-STD-810H compliant and meets military quality standards for resistance to environmental stresses such as vibration, extreme temperatures and humidity. This makes ulefone smartphones a great option for people working in challenging environments. Another notable feature is that the drop resistance of the phone is up to 2 meters, allowing it to withstand accidental falls.

The phone can also reach brightness under normal conditions and reach up to 2200 nits at a height of 900 nits. This ensures visibility even in direct sunlight. The screen is protected by Vics, Corning Gorilla Glass, known for its scratch and impact resistance. On the back there is also a 1.04-inch screen with a resolution of 340 x 340 pixels, and a 1.04-inch screen that provides users with additional notification or quick view information.
