Description
Overview & Display
The Samsung Galaxy M31 Prime presents a familiar, yet functional design. Its build incorporates a glass front protected by Gorilla Glass 3, paired with a plastic back and frame, resulting in a device that weighs 191 grams. The 6.4-inch Super AMOLED display promises a vibrant viewing experience, boasting a resolution of 1080 x 2340 pixels and a 19.5:9 aspect ratio. With a peak brightness of 420 nits, the screen should remain reasonably visible even in brighter conditions. This suggests a solid multimedia experience for enjoying videos and photos on the go, aided by the high screen-to-body ratio of 84.1%.
Under the hood, the Galaxy M31 Prime utilizes an Exynos 9611 chipset, paired with either 6GB of RAM and 64GB of storage or 64GB of storage with 6GB of RAM. The UFS 2.1 storage type provides relatively quick read/write speeds. The octa-core CPU, featuring a combination of Cortex-A73 and Cortex-A53 cores, should handle everyday tasks and moderate multitasking with ease. Running Android 10 with One UI 2.0, users can expect a familiar and intuitive software experience, making it well-suited for daily use.
Camera & Battery
