The Samsung Galaxy A51 is a relatively affordable Android phone that you can buy if you can’t afford the Galaxy S21 or can’t buy a Samsung Galaxy S20 fan version in your area.
The low price comes with downgrades from Samsung’s most expensive phones. The back is plastic rather than glass, the cameras are not so good (although there are five), the chipset is less powerful, and there are no extras as water resistant.
The classic Samsung features you get on the Galaxy A51 include a thick AMOLED screen and software that looks like the Galaxy S21 series.
Don’t expect miracles from cameras. Like many affordable quad-camera phones, it looks like a dual-lens device with few incomplete extras, although its third-party macro camera is better than most in this category and offers a different way of taking pictures.
Since we tested this device, Samsung has also introduced a little tune version of the Galaxy A51 5G. We haven’t tested this device yet, but the big difference is that it has a different chipset with extra 5G connectivity.
Samsung Galaxy A51 offers some of Samsung’s most advanced phones design. But there is some evidence that this is not part of the more expensive Galaxy S series.
The screen edges are thin and the front camera sits in Samsung’s ‘Infinity O’ holes. However, the rear is made of plastic instead of glass and the front camera does not mix with the front glass and much more.
But the lower layers are more reflective, making the Samsung A51’s selfie camera stand out as a smaller monocle.
However, it does have a slightly unique rear.
As with other recent A-series phones, the Samsung Galaxy A51 lines have sliding lines, cutting shapes on the back, each with a slightly different look.
The lower part has a fine-line pinstrip pattern, for example, sitting beneath the plastic layer on top.
This is a relatively subtle look, but when capturing the light of the Samsung Galaxy A51, you see bright rainbow tones that form laser streaks on the curved edges.
They could pass on to the more expensive Samsung in the distance, especially as the large four-lens camera case on the back looks to be advanced. This phone is also reasonably sized, made for media and wider than the Galaxy S20.
Like most phones at this price point, the Samsung Galaxy A51 does not offer official water resistance. But it has a 3.5mm headphone port, which is useful if you haven’t yet converted to Bluetooth headsets.
It also features a fingerprint reader on the screen, another attempt to make the Samsung Galaxy A51 look like a high-end phone.
However, it is not a good scanner. It is slower than most and it does not notice if your fingers are a little wet or you are not very careful about the position of your thumb.
Cheap phones with less modern rear scanner pads unlock more quickly and reliably.
OLEDs provide much deeper colors and always have better contrast than LCDs because they use luminous pixels instead of universal backlighting. However, this is not one of Samsung’s best OLED panels, and there are some obvious problems.
The less advanced OLED panels get a little blue from the angle, usually when you turn the phone screen left or right. This is rarely a big problem, because we all see our phones from the front, don’t we?
But that effect comes from another direction on the Samsung A51. Hold it in a calm and sloping way, and that blue at the top of the screen.
This is only apparent when significant parts of the screen are as white as web pages, but it immediately shows that this is not one of Samsung’s best OLEDs.
Samsung Galaxy A51 offers other common benefits of OLED screens. Its optional vivid screen mode is very saturated and contrast in the darkroom is clearly better than LCD phones at this price.
The screen brightness is also quite good, if not the same as the Galaxy S20. The Samsung Galaxy A51 accelerates when taken outdoors on a clear day. It changes color and contrast to enhance visibility in difficult conditions.
