Running ColorOS 15, the phones introduce features like intelligent pre-loading, improved touch response, and a one-click performance rejuvenation tool.
The F31 series uses a 360° Armor Body design with an aerospace-grade AM04 aluminium alloy frame that’s 10% stronger than its predecessor. The AGC DT-Star D+ glass offers added screen protection, while triple IP certifications (IP66, IP68, and IP69) make the devices resistant to dust, immersion, and even high-pressure water jets at up to 80°C. Oppo says the phones can withstand oily fingers, rain, and even 18 everyday liquids like tea and detergent water.
