With the K12x, Oppo presents an interesting mid-range smartphone that offers up to 12 GB of RAM, 512 GB of flash memory, and a 120 Hz OLED display with 1,080p+ resolution despite its relatively low price.

The latest mid-range smartphone from Oppo has a modern design with a flat frame, relatively slim screen edges, a pill-shaped camera module, and an eye-catching green version. This not only makes the device look more stylish than many similarly priced competitors, but the features are also impressive considering the price.

Oppo has installed a 6.67-inch, 120 Hz OLED panel that achieves a resolution of 2,400 x 1,080 pixels and a peak brightness of 2,100 nits, even if "only" 1,200 nits are possible in full-screen HBM mode. The battery has an above-average capacity of 5,500 mAh and can be charged via USB-C with up to 80 watts. The device has 256 GB to 512 GB of flash memory, which can be expanded using a microSD card.


The 16 MP selfie camera sits in a central punch-hole, while the rear houses the 50 MP main camera and a 2 MP sensor. Oppo saves a little on the processor and installs the Qualcomm Snapdragon 695 5G from 2021, which has two ARM Cortex-A78 performance cores with clock speeds of up to 2.2 GHz and six Cortex-A55 efficiency cores at 1.7 GHz. The 191-gram smartphone comes with Android 14. Oppo has not confirmed how long the Oppo K12x will be supplied with Android updates and security patches.

Prices and availability

The Oppo K12x will initially launch in China with 8 GB RAM and 256 GB flash memory for 1,299 yuan (approx. 165 euros), the top model with 12 GB or 512 GB memory costs 1,799 yuan (approx. 229 euros).
