OnePlus has long been known as the “flagship killer” brand, offering high-end specifications and features at a more affordable price than the industry giants. With the release of the OnePlus 12, the company has again raised the bar, delivering a smartphone that can easily compete with flagships. In this comprehensive review, we’ll dive deep into the features and performance of the OnePlus 12 to see if it’s the right choice for you.

Design and Display

The OnePlus 12 boasts a stunning, premium design that immediately catches the eye. The phone features a sleek, glass-and-metal construction with a subtle, matte finish that gives it a sophisticated look and feel. The device is available in three color options: Midnight Black, Glacial Green, and Stellar Blue, each with a unique charm.

The display is equally impressive, with a large 6.55-inch AMOLED panel that offers a smooth 120Hz refresh rate and a 2400 x 1080 pixels resolution. The display is also HDR10+ certified, ensuring vibrant and accurate colors, deep blacks, and high contrast. The screen is protected by Corning Gorilla Glass Victus, making it resistant to scratches and cracks.

One of the standout features of the OnePlus 12’s display is the in-display fingerprint sensor. This cutting-edge technology allows you to unlock your device with a simple touch, without needing a physical fingerprint reader. The sensor is fast, accurate, and seamlessly integrated into the display, providing a futuristic user experience.


Under the hood, the OnePlus 12 is powered by the latest Qualcomm Snapdragon 8 Gen 3 processor, one of the most powerful mobile chipsets on the market. This flagship-grade processor, coupled with up to 16GB of LPDDR5 RAM and up to 512GB of UFS 3.1 storage, ensures lightning-fast performance for all your daily tasks, from browsing the web to gaming and multitasking.

The phone’s performance is further enhanced by OnePlus’ proprietary Oxygen OS 13, which is based on the latest Android 13 operating system. Oxygen OS 13 offers a clean, bloat-free user interface with various customization options, ensuring a smooth and responsive user experience.

In terms of benchmarks, the OnePlus 12 consistently outperforms its competitors, scoring high in both single-core and multi-core tests. This translates to a snappy and responsive user experience, with apps and games loading quickly and running smoothly.


The OnePlus 12 features a versatile quad-camera setup on the rear, headlined by a 50MP primary camera with optical image stabilization (OIS). This high-resolution sensor, combined with OnePlus’ advanced image processing algorithms, delivers stunning, detailed photos in a variety of lighting conditions.

The primary camera comprises a 16MP ultra-wide-angle lens, an 8MP telephoto lens with 3x optical zoom, and a 2MP depth sensor. This combination of lenses allows you to capture wide landscapes, zoom in on distant subjects, and create beautiful portrait shots with a natural bokeh effect.

The camera app on the OnePlus 12 is also packed with features, including a Pro mode for manual control, a dedicated night mode for low-light photography, and various AI-powered enhancements to optimize image quality. The phone can also record 4K video at 60fps, with the OIS system helping to stabilize your footage.

One of the most impressive aspects of the OnePlus 12’s camera is its performance in low-light conditions. The phone’s advanced night mode and high-resolution sensor work together to capture detailed, well-exposed images, even in challenging lighting environments.
