The Galaxy A51 has an Infinity-O display. The centered punch hole for the front camera allows for a slimmer top bezel.The subtle curves at the back allow for a comfort.
The 3.5mm headphone jack, USB Type-C port and speaker are all positioned at the bottom.
The Galaxy A51 comes with a 6.5-inch Infinity-O Super AMOLED Full HD+ display, with 1080×2400 pixel resolution and 20:9 aspect ratio. It’s marginally taller than the Galaxy A50’s 6.4-inch panel. The bezels are a bit slimmer than its predecessor.
An in-display optical fingerprint sensor is also present. It’s much better on the Galaxy A51. It doesn’t struggle nearly as much as it did on its predecessor.The fingerprint sensor works as it should for the most part.
The Galaxy A51 has a 48-megapixel f/2.0 primary and a 12-megapixel ultra-wide f/2.2 camera that has a 123-degree field of view. It retains the 5-megapixel f/2.2 depth camera of its predecessor. The Galaxy A51 also has the distinction of being Samsung’s first smartphone to feature a 5-megapixel f/2.4 macro camera.
The main camera doesn’t actually output 48MP photos. It uses pixel binning technology to output 12MP photos. Without going into too many technical details, pixel binning allows for more accurately exposed and detailed images as it combines 4 pixels into 1 superpixel. This superpixel contains four times the amount of data compared to a single pixel in a 48MP image. The resulting images are nice and sharp with great color reproduction. Low-light performance is certainly better than it was on the Galaxy A50. It doesn’t tend to overexpose shots as much under artificial lighting.
