Design & Build Quality

The Samsung Galaxy M31 boasts a solid yet stylish design. It combines a glass front protected by Corning Gorilla Glass 3 with a plastic back and frame, a choice that keeps the device lightweight at 191 grams while providing adequate durability. The dimensions of the phone stand at 159.2 x 75.1 x 8.9 mm, making it comfortable to hold and use with one hand. Available in colors like Ocean Blue, Space Black, and Red, the Galaxy M31 offers a sleek look without compromising on sturdiness. The dual SIM capability provides users with added flexibility in managing multiple connections simultaneously.

Display Features

The Galaxy M31 features a 6.4-inch Super AMOLED display, which is one of its standout attributes. With a resolution of 1080 x 2340 pixels and a screen-to-body ratio of approximately 84.1%, the display offers vibrant colors, deep blacks, and an immersive viewing experience. The pixel density of ~403 PPI ensures sharp visuals, making it suitable for media consumption, whether you are streaming videos or playing graphic-intensive games. Moreover, the peak brightness of 420 nits makes it reasonably usable in brightly lit environments.

Photography is a major highlight of the Samsung Galaxy M31, thanks to its versatile quad-camera setup. The primary sensor is a 64 MP wide-angle camera with an aperture of f/1.8, ensuring detailed and bright photos even in challenging lighting conditions. It is complemented by an 8 MP ultra-wide sensor with a 123-degree field of view, ideal for capturing expansive landscapes or group photos.

Additionally, the device includes a 5 MP macro lens and a 5 MP depth sensor, which enhance close-up shots and portrait photography, respectively. The camera system supports 4K video recording at 30fps and comes with features like LED flash, panorama, and HDR for enhanced photography.
