Given how popular the Galaxy A50 turned out to be, the Galaxy A51 had big shoes to fill. It was the first of the 2020 Galaxy A series that Samsung unveiled in December 2019. Samsung’s strategy of packing mid-range devices with technology well and truly continued with the Galaxy A51. The device was among the first in its class from Samsung to feature a macro camera at the back.

Samsung also took a new design direction with the 2020 Galaxy A series. The Galaxy A51 was the first device to give us a glimpse of this new direction. It adopts a new L-shaped camera array and places all of the buttons on the right side of the frame. The centered punch hole for the front camera also makes its way from the Galaxy Note 10 to more affordable devices with the Galaxy A51.


Much like its predecessor, the Galaxy A51 is made from a material that Samsung is calling Glasstic. It’s not actual glass, but plastic that resembles glass. It measures 158.5 x 73.6 x 7.9mm and weighs 172g. The centered punch hole display always for slimmer bezels overall.

The volume and power keys are placed at the right side of the frame. There’s an L-shaped camera module at the back. The device retains a 3.5mm headphone jack and has a USB Type-C port at the bottom. The speaker can also be found at the bottom.


The Galaxy A51 is powered by an Exynos 9611 processor and is offered in 4/6GB and 64/128GB RAM and storage variants respectively. The 6.5-inch FHD+ 1080×2400 pixel resolution panel has an in-display fingerprint sensor as well. The 4,000mAh battery supports 15W fast charging.

The full list of specifications for this device can be found on our Galaxy A51 specs page.


The Galaxy A51’s display has slimmer bezels than its predecessor courtesy of the Infinity-O display which puts the front camera in a hole inside the panel itself. The panel measures 6.5-inches with FHD+ resolution.


The Galaxy A51 really kicks things up a notch in the camera department. Samsung has equipped the device with a 48-megapixel f/2.0 primary sensor in addition to a 12-megapixel f/2.2 ultrawide and 5-megapixel f/2.2 Depth sensor. It also comes with a 5-megapixel f/2.4 Macro camera which allows for more detailed closeups.


The Galaxy A51 comes with Android 10 installed out of the box. That was to be expected as the new Galaxy A series for 2020 wouldn’t have launched with Android Pie. This also makes it the first Samsung smartphone to come with Android 10 and One UI 2.0 pre-installed. Check out our One UI 2.0 feature focus series to learn more about all of the new features.


Samsung unveiled the Galaxy A51 at a special event in Ho Chi Minh City, Vietnam on December 12, 2019. December 27, 2019 is when the device is released. It’s going to be available in Prism Crush Black, Prism Crush White, Prism Crush Pink, and Prism Crush Blue colors. The Galaxy A51 is priced at 7,990,000 Vietnamese Dong which is around $350.
