OPPO is emphasising the ruggedness of the F31 series with several protective measures. The phones are certified with three IP ratings — IP66 against dust and splashes, IP68 for immersion in up to 1.5 metres of water, and IP69 for withstanding strong water jets. OPPO also claims the devices have been exposed to eighteen different liquids, such as coffee, soft drinks, and soap water, as part of testing. To further ensure reliability, the series integrates water-resistant microphones, reinforced SIM card trays, and a drainage channel for speakers.
For durability against drops, OPPO says the F31 range adopts a 360-degree Armour Body structure that has cleared seven MIL-STD-810H tests. These include endurance against shock, dust, sand, and extreme temperatures. The devices are said to survive falls from as high as 1.8 metres, supported by features like shock-dampening pads around vital hardware, foam cushions for internal parts, reinforced edges, and slightly raised camera modules. The chassis uses aerospace-grade aluminium alloy, and the display is protected by AGC DT-Star D Plus glass.
