Samsung Galaxy A51 was released in December 2019 and you could say that it was a budget option form Samsung. However, with the low-price bracket, you get some obvious downgrades than the flagship smartphones. Such as a less powerful chipset, plastic back rather than a glass back, and the absence of extra features like water resistance. However, if we look at the price tag of $399 everything is justifiable. The affordability of the phone truly made it an instant hit. So, let’s do a comprehensive review of this smartphone is that you could make an informed decision before buying it.


  • Dimension – 158.5 x 73.6 x 7.9mm
  • Weight – 172g
  • Colors – black, blue, white, and pink
  • Plastic back with a distinctive look
  • In-screen fingerprint scanner

The phone does not have the same design traits as the flagship phones from Samsung. But it is pretty having a pretty impressive design on its own. The display borders are pretty slim and the back of the phone is made from plastic. The front camera is covered by the front glass and does not merge well. The power buttons and the volume controls are also made from plastic and have the same color as the back of the phone.

The phone back has an intersecting line finish which gives a slightly different look than other smartphones. At the bottom of the phone, you could feel the texture of thin lines. All of that looks very nice when you see a shimmering rainbow at the curved edges. It is mainly due to the reflection of the light but it looks unique.

Well, the phone is not water-resistant so you have to take precautions on a rainy day. Moreover, you would find a 3.5mm headphone and an in-screen fingerprint scanner. The scanner is not the greatest as it is a bit slow and would fail to recognize if your fingers are wet.

Real Also: Which smartphone is the best Samsung S20 or iPhone 11?


  • 6.5 inches Super AMOLED screen 
  • Resolution – 1080 x 2400
  • Infinity-O punch hole

The display of this smartphone is one of the best things about this device. The huge AMOLED screen of 6.5 inches and the full HD resolution is an instant win. Every one of us knows that OLED screens deliver much deeper color, better contrasts, and have a better backlight. Therefore, you could expect a better quality of screen than an LCD phone at this price. However, the screen might not be in the same league as the Galaxy S20. You would feel very comfortable with the brightness of the screen. The screen even adjusts the color and contrast to enhance visibility in daylight.


  • Quad lens rear camera
  • 48MP, 12MP, 5MP, and 5MP depth sensor
  • Selfie camera with 32MP sensor

Do not get excited with the four lenses it would not do any miracles. You could understand the use of these lenses by their purpose.

  • The 48MP is the main camera lens
  • 12MP is the ultra-wide lens
  • 5MP is the macro lens used for close-up macro images
  • lastly, the 5MP is the depth sensor

you would not get any zoom option in the camera which is a clear sign that all these lenses are just used to bulk up the numbers. So, you could say that this phone has a budget camera of two lenses. The main lens of the camera just like every 48MP phone sensor takes 12MP images and then uses pixel binning to improve the quality. The ultra-wide lens in the camera clicks unreal photos such as neon-colored grass due to the high saturation of colors. It offers fewer details and lowers dynamic range than the main lens. If we talk about the macro lens then it would surely not win you any competition but it is fun to play with.

Talking about the video recording capabilities you shoot videos at 4K with 30fps. However, I would recommend you stick with 1080p as the video become highly unstable at 4K. The selfie camera is very handy and you could click all sorts of selfies with it. the quality of the image is not that high but the processing done on it does enhances the lighting.


  • Exynos 9611 chipset
  • 4GB RAM
  • 128GB built-in storage

You do not get the QUALCOMM snapdragon with the galaxy A51 like the other flagship phones of Samsung. However, the performance of the Exynos 9611 chipset is very similar to the snapdragon 665. The mart phonies pretty responsive and the 4GB RAM provides a flawless gaming experience.

Battery Life:

  • 4000mAh battery
  • 15W fast charger
  • Approximately 24 hours of backup

The most important feature in modern smartphones is longer battery life. With galaxy A51 you get a very reasonable battery capacity. However, the longevity of the battery entirely depends on the usage. For a normal person, it would easily last a whole day. Moreover, the 15W super-fast charger takes less than an hour to fully charge the battery.
