Samsung Galaxy A51
Refined and stylish design
Lewis Hilsenteger aka @UnboxTherapy
"The device for you if battery life is a big deal to you." "Bigger displays, nicer displays, with no bezels! They are AMOLED, with a higher resolution."
"The Samsung Galaxy A51 is a winner thanks to plenty of high-end features and low-end price.”
"If you're after a smartphone with a big screen, big battery and plenty of photography features, but don't want to break the bank, the Samsung Galaxy A51 could well be the phone for you.” Samsung Galaxy A51, TechRadar, 01/2020
Big screen. Small price
A51's Infinity-O Display optimizes visual symmetry. Now you can game, watch, surf, and multi-task without interruption on a 6.5" FHD+ widescreen display—all powered by Super AMOLED technology. Enjoy a smartphone experience that minimizes the bezel and maximizes each inch of screen space.
*Measured diagonally, the screen size is 6.5" in the full rectangle and 6.3" with accounting for the rounded corners. Actual viewable area is less due to the rounded corners and the camera cutout.
Designed for a refined level of style and comfort
The rhythmical pattern of A51's design theme comes in smooth and elegant pastel shades including Prism Crush Black, White and Blue. A premium gloss finish adds the perfect touch of style to its sleek and slim body, perfectly blending of style with in-hand comfort.
Awesome Quad camera to capture more
Go ultra high-res with a 48MP Main Cam for crisp, clear photos day and night. A 123° 12MP 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.
Capture more of the 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.
*Ultra wide experience (photo/video) is supported for rear camera only.
Macro Cam that captures the up-close details
Quad Cam’s built-in 5MP Macro Cam (40mm) shoots with clarity and quality, helping you bring out the ultra-fine details of your close-up shots. Apply and adjust natural background blur (Bokeh) to isolate your subject and increase its visual impact.
*Macro Camera feature supported for rear camera only.
Shoots smooth and steady just like the pros
Galaxy A51 records like a pro-level action camera utilising the Ultra Wide Camera and predictive software. Super steady gives you smooth live videos, even when your journey is on the adventurous side.*

**Actual storage available may vary depending on pre-installed software.

Attention-grabbing selfies made easy
You want your selfie to look good. So for stunning daytime looks, Galaxy A51's 32MP front camera gives you clear, high-resolution photos. And with Selfie focus to gently blur the background, your face becomes the star.
Long lasting battery at no extra charge
When out living life, you need a phone that can last. A 4,000mAh (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 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 3,890 mAh. Actual battery life may vary depending on network environment, usage patterns and other factors.
Premium storage at no extra cost
Galaxy A51 has fast processing and spacious storage, so you can focus on now. An advanced Octa-core processor and up to 4GB of RAM deliver smooth and efficient performance. Download more and delete less with up to 128GB internal storage. Add even more with a 512GB microSD card.*
*MicroSD card sold separately. External memory can be used to store media (photos, video and music files) but no applications.
