Features

Awesome screen built for cinema

Immerse yourself in the large 6.4-inch Infinity-U Display of Galaxy A31. A wide aspect ratio fills your screen with content from edge to edge. Watch your favorite videos, games and live streams in vivid FHD+ Super AMOLED.

* Images simulated for illustrative purposes.
** Infinity Display: a near bezel-less, full-frontal glass, edge-to-edge screen.
*** Measured diagonally, the screen size is 6.4' in the full rectangle and 6.2' with accounting for the rounded corners. Actual viewable area is less due to the rounded corners and the camera cutout.

Slim on the outside, big on the inside

Everything you want in a phone in a slim body. Housing a large 5,000mAh(typical) battery in the 8.6 mm-thick device, Galaxy A31 fits right in your hand and comes in a geometric design with a glossy finish. Choose from Prism Crush Black, Prism Crush White, Prism Crush Blue, or Prism Crush Red.

* Color availability may vary by country or carrier.
** Typical value tested under third-party laboratory condition. Typical value is the estimated average value considering the deviation in battery capacity among the battery samples tested under IEC 61960 standard. Rated (minimum) capacity is 4,860mAh. Actual battery life may vary depending on network environment, usage patterns and other factors.

Awesome Quad camera to capture more

Go ultra high-res with a 48MP Main Cam for crisp, clear photos day and night. A 123° 8MP Ultra Wide Cam captures more of the view. Choose the upgraded 5MP Macro Cam for highly refined close-ups, and make sure the subject always stands out with the 5MP Depth Camera’s multiple Live Focus effects.

* Color availability may vary by country or carrier.

Awesome battery, the marathon champ

When out living life, you need a phone that can last. A 5,000mAh (typical)* battery gives you the power to stream, share and game on. And if you start running low, plug in and power up with 15W Fast Charging.

Typical value is the estimated average value considering the deviation in battery capacity among the battery samples tested under IEC 61960 standard. Rated (minimum) capacity is 4,860 mAh. Actual battery life may vary depending on network environment, usage patterns and other factors.
