Oppo launched the K12x in India in July 2024 as an online-focused budget phone sold through Flipkart. It carried MIL-STD-810H certification and an IP54 rating, positioning itself as a tough phone at a low price. Competitors included the Redmi 13 5G, Samsung Galaxy M15 and Realme Narzo 70x. For buyers who mostly message, stream and browse, that trade-off is easy to live with.
The 6.67-inch LCD display refreshes at 120Hz with an HD+ resolution, which makes scrolling smooth but text less crisp. The Dimensity 6300 handles daily tasks such as messaging, browsing and video well, but heavy games are a stretch. Oppo also highlighted Splash Touch, which lets the screen respond with wet fingers. ColorOS 14 on Android 14 feels polished.
The 32 MP main camera takes acceptable daylight photos, with a 2 MP depth sensor alongside. The 8 MP selfie camera is basic. The 5,100 mAh battery comfortably lasts more than a day, and 45W charging is quick for this price. Against the Redmi 13 5G, it offered better durability and faster charging, while Redmi had a sharper display and a stronger camera.
