Oppo F31 Series marketing posters leaked, revealing design and colour options

We’ve been hearing a lot about the upcoming Oppo F31 series. Unlike the F29 line-up, Oppo is expected to launch three models this time: the Oppo F31, Oppo F31 Pro, and Oppo F31 Pro+. The same tipster who shared the early rumours has now posted marketing posters for the series, which also appear to reveal the colour options.

Oppo F31 Series posters leaked

We recently spotted the Oppo A6 5G on China’s TENAA listing, and from the leaked poster, the vanilla Oppo F31 5G looks quite similar in design. Its camera module sits in the top-left corner, shaped like a rounded square with twin rounded-square cut-outs stacked vertically. The primary lens occupies the upper slot, with the secondary lens below. Beside it are circular cut-outs for the LED flash and an additional sensor. Colour options for this model include a pink-coral finish with a wave pattern, a light silver/white shade, and a dark blue variant.

The Pro model also has a flat back, but its camera module is centred near the top. The square-shaped housing features a 2×2 layout with three lenses and a flash. It rises slightly from the panel with a colour-matched rim for contrast. The poster shows two colour options of light gold/peach with smooth flowing accents, and a dark grey/graphite tone.

And lastly, the Pro+ variant is revealed to feature a large circular camera module in the centre of the back, surrounded by a shiny rim. Inside the circle, there are three big camera sensors arranged in a triangle, along with an LED flash and a small dot in the middle. The design looks quite similar to the OnePlus Ace 5 (China). As for colours, the poster shows three colour options of pearl pink with a wavy pattern, a pinkish tone with a light shine, and a deep blue with a gradient effect. Honestly, the posters aren’t of the best quality, so I’ve had to make out the details as carefully as I could.

Earlier, the same tipster also shared key specifications. The F31 may use MediaTek’s Dimensity 6300, the F31 Pro may step up to the Dimensity 7300, and the F31 Pro+ is said to run Qualcomm’s Snapdragon 7 Gen 3. All three phones are believed to include a 7,000mAh battery, with the F31 and F31 Pro tipped to support 80W fast charging, while the F31 Pro+ charging speed remains unclear. The launch is rumoured for mid-September 2025—likely on the 12th or 14th—and a 12GB/256GB variant has previously been tipped for the F31 Pro+. Speaking more about this, IP68/69 rated protection can be expected, and Oppo may market this smartphone as “Next Level Durability.“.
