Bengaluru, September 15, 2025 – OPPO India has officially launched the F31 5G Series, the latest addition to its popular F-lineup, engineered to meet India’s growing demand for durability, long battery life, and smooth performance. Available in three models – F31 Pro+, F31 Pro, and F31 – the series combines rugged design, advanced heat management, AI-powered features, and reliable 5G connectivity to deliver what OPPO calls the “smoothest and most durable smartphone experience under ₹35,000.”

Built for Durability: Stronger Frames & Triple IP Ratings

With 79% of Indian buyers prioritising durability, OPPO has designed the F31 5G Series with a 360° Armor Bodyand multi-layer airbag protection. The aerospace-grade AM04 aluminium alloy frame is 10% stronger than its predecessor, while AGC DT-Star D+ glass offers reinforced protection.

The devices are certified IP66, IP68, and IP69, making them resistant to dust, immersion, and even high-pressure hot water jets up to 80°C. The series is also tested against 18 everyday liquids such as tea, coffee, and detergent water—ideal for India’s diverse conditions.
