Display Quality

The Galaxy M31 Prime features a brilliant 6.4-inch Super AMOLED display, offering vibrant colors and deep contrasts. With a resolution of 1080 x 2340 pixels and a 19.5:9 ratio (~403 ppi density), the visuals are stunning and clear, making it an excellent choice for multimedia consumption. The screen-to-body ratio of approximately 84.1% is a testament to its modern design, ensuring minimal bezels and maximizing screen real estate. The Corning Gorilla Glass 3 protection ensures durability against scratches and minor impacts.

Performance and Software

Under the hood, the Samsung Galaxy M31 Prime is powered by the Exynos 9611 chipset, which is built on a 10 nm process. The octa-core processor (4x2.3 GHz Cortex-A73 & 4x1.7 GHz Cortex-A53) coupled with the Mali-G72 MP3 GPU ensures smooth multitasking and a seamless gaming experience. The device runs on Android 10 with Samsung’s One UI 2.0, offering a user-friendly interface and a plethora of customization options.

With 6GB of RAM, the device efficiently manages tasks and applications, reducing lags and facilitating smoother transitions.

Camera Capabilities

Photography enthusiasts will appreciate the quad-camera setup on the Galaxy M31 Prime. The primary 64 MP wide camera with an aperture of f/1.8 excels in capturing sharp and detailed photos. An 8 MP ultrawide camera (f/2.2, 123°) is perfect for capturing landscapes and group photos. The 5 MP macro (f/2.4) and 5 MP depth (f/2.2) cameras offer creative photography options. For video recording, the camera supports 4K at 30 fps and 1080p at 30 fps with gyro-EIS for stability. The front camera features a single 32 MP lens with HDR support, perfect for high-quality selfies and video calls.

Battery Life

The device is equipped with a robust 6000 mAh non-removable Li-Po battery, which supports 15W wired charging. The battery is one of the standout features of the Galaxy M31 Prime, ensuring extended periods of use without the need for frequent recharging, making it ideal for power users and travelers.

The Samsung Galaxy M31 Prime supports GSM, HSPA, and LTE technologies, offering widespread network compatibility and fast data speeds with HSPA and LTE. It includes Wi-Fi 802.11 a/b/g/n/ac for fast wireless networking, Bluetooth 5.0 for efficient data transmission, and GPS, GLONASS, GALILEO, and BDS for accurate positioning services. However, it does not support NFC, limiting contactless payment options.
