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 favourite videos, games and live streams in vivid FHD+ Super AMOLED.
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.
Awesome Quad camera to capture more
Go ultra high-res with a 48MP Main Cam for crisp, clear photos day and night. A 123° Ultra Wide Cam captures more of the view. Choose the upgraded Macro Cam for highly refined close-ups, and make sure the subject always stands out with the Depth Camera’s multiple Live Focus effects.
Capture more of view from the same spot
Capture the wider world with the Ultra Wide Camera's wider field of vision. And with the 48MP Main Camera, your story stays bright and clear throughout the day.
Macro Cam that captures the up-close details
Quad Cam’s built-in Macro Cam (40mm) shoots with clarity and quality helping you bring out the ultra-fine details of your close-up shots. Apply natural background blur (Bokeh) to isolate your subject and make it stand out.
Depth Camera brings your subject into the spotlight
The Depth Camera lets you adjust the depth of field before and after you nail the shot. It is designed to reduce unwanted background noise from your images to help make them look more professional.
Attention-grabbing selfies made easy
You want your selfie to look good. So for stunning daytime looks, Galaxy A31's 20MP front camera gives you clear, high-resolution photos. And with Live focus to gently blur the background, your face becomes the star.
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.
Give yourself more room to play
Galaxy A31 has fast processing and spacious storage so you can focus on now. An advanced Octa-core processor and 4GB of RAM deliver smooth and efficient performance. Download more and delete less with 128GB internal storage. Add even more with a 512GB microSD card.
Game Booster gives you the edge
Maximise performance with Game Booster. Cut distractions and up your game with a dedicated interface and easy-to-reach menu. Frame Booster gives graphics smooth, life-like motion. And play at your best as Game Booster can learn your usage patterns to help optimise battery, temperature and memory.
Defense-grade security. Protect what matters to you.
Built into the phone's hardware and software from the start, Samsung Knox is designed to protect your phone from the minute it's turned on. Offering multi-layered security, it can defend your most sensitive information from malware and malicious threats.
Your fingerprint is the key
Galaxy A31 comes with high-tech biometric authentication. The On-Screen Fingerprint scanner is designed to recognise your unique fingerprint, so you are the only one who can press and unlock in one easy move.
