Samsung Galaxy A51 Display Screen:


Samsung Galaxy A51 Review


Samsung has a history of making phones with beautiful display screens and Samsung continues that trend with the Galaxy A51.


This phone comes with a beautiful 6.5-inch Super AMOLED display screen that has a 1080p resolution and a 20:9 aspect ratio.


The colors are rich and vibrant on this display screen and the picture quality is great when viewing it from different angles, this display screen is made from Corning Gorilla Glass 3.


The Galaxy A51 has the Always-on display feature which gives you the ability to look at your phone to see the time and notifications without having to touch it.


However, you must remember that when the Always-on display is enabled the battery will drain at a faster rate.


If you dislike the colors on the display screen you can go to Settings > Display > Screen Mode, to modify the color settings.


You can choose between a Vivid mode which looks more saturated with colors that pop. Or you can choose Natural mode which displays natural colors which look a bit more balanced. This is great because everyone has different color preferences.


Samsung Galaxy A51 Design:


The Galaxy A51 has a nice look and feel to it, however, it’s made from plastic. Nevertheless, this plastic is durable, so it’s not easily broken but it scratches easily.


The power and volume buttons are located on the right edge of the phone. On the bottom edge of the phone, you will find the USB-C port that’s used for charging the phone as well as a 3.5mm headphone jack.


I think it’s great that Samsung has a 3.5mm headphone jack on this phone because this is something that many smartphone users enjoy using but many smartphone manufacturers have been getting rid of it.


When you turn the phone over, you will notice that there’s a big camera bump at the back of the phone that houses four different cameras.


Located at the top of the display screen in the middle there’s a punch-hole selfie camera, this looks a bit different from the teardrop notch that’s featured on the Galaxy A50.


I like the punch-hole camera on the Galaxy A51 better because I think it’s less noticeable. This phone does not have an official IP water resistance rating, so it’s not waterproof.


Fingerprint Scanner:


The Galaxy A51 comes equipped with an optical fingerprint scanner that’s conveniently hidden below the display screen.


This fingerprint scanner works fairly well but it’s not the fastest or the most accurate on the market by any means.


When the fingerprint scanner is pressed, there’s a slight delay between the time it’s pressed and when the phone unlocks.


Samsung Galaxy A51 User-Interface:


Samsung Galaxy A51 ReviewThe Galaxy A51 features the latest Android operating system, Android 10 on top of Samsung’s One UI 2.0.


The Galaxy A51 has a gesture navigation system. You have the ability to switch to the gesture navigation by going into Settings, Display, and Navigation Bar.


When gesture navigation is enabled you can swipe up from the bottom of the display screen to go to the home screen.


You can also swipe from the bottom of the display screen and hold it for a few seconds to go to your recent apps.


If you swipe from either side of the phone, it will take you back one step. Aside from this, the user interface is very much the same as it is on the premium Samsung phones.


Samsung Galaxy A51 Cameras:


Samsung Galaxy A51 Review


One of the most noticeable upgrades the Galaxy A51 has over its predecessor from last year is the cameras.


The Galaxy A51 has 4 cameras located at the back of the phone which consist of a new 48MP primary camera with an f/2.0 aperture, 0.8µm pixels, and phase detection Auto Focus.


There’s a 12MP ultra-wide camera with an f/2.2 aperture with a focal length of 33mm and a 5MP dedicated macro camera with an f/2.4 aperture with a focal length of 40mm.


There’s also a 5MP Time Of Flight (TOF) camera with an f/2.2 aperture with 1.12µm pixels.


The selfie camera is a 32MP camera with an f/2.2 aperture with 0.8µm pixels and it supports 1080p video.


The resolution on these cameras is higher than that of the cameras on last year’s Galaxy A50.


There is a Live Focus mode that works wonders when you want to focus on the subject while blurring the background.


The Galaxy A51 does not have a telephoto camera and these cameras do not apply digital crop.


So when taking photos of people from further away you will get the best results with the Live Focus mode.


However, Live Focus does not work as well when capturing photos at close range. The selfie camera does a great job when taking selfies and it records videos at 1080p.


If you’re taking a selfie and you’re the only person in the picture you can use the zoomed mode.


However, if you would like to fit multiple people into the photo, the wide mode would work best.


Samsung Galaxy A51 4K Video:


You can record 4K video at 30fps on the Galaxy A51 with the primary camera, this is a nice upgrade over its predecessor. But there are some limitations that you should be aware of.


Even though the Galaxy A51 can shoot 4K video, the video quality is not equivalent to 4K video that’s shot on a premium phone such as the Galaxy S10.


This is due to the fact that the 4K video on the Galaxy A51 shows less detail, even though the camera is a high-resolution camera.


The reason for the less than spectacular 4K video quality is a result of poor dynamic range.


This is most noticeable when looking at brighter parts of a scene that have too much exposure which looks a bit unnatural.


Nevertheless, there’s a continuous auto focus feature that works well, it can focus fast on the subject due to the phase detection pixels.


When you start recording video with the primary camera, there’s no way to seamlessly switch to the ultra-wide camera at a later time.


If you would like to record video with the ultra-wide camera you must select it before you start recording and you do not have the ability to zoom while shooting video with this camera.


The Galaxy A51 comes with 2 different types of video stabilization modes that you can choose from standard and Super Steady modes. However, video stabilization isn’t available when shooting 4K video.


The video has to be shot at 1080p if you would like to use video stabilization. The video quality is good when shooting videos in a well-lit setting but it struggles to perform in a darker setting.


Samsung Galaxy A51 Battery Life:


The Galaxy A51 comes equipped with a massive 4,000mAh battery, this is the same size battery as that of its predecessor.


The battery life on this phone is good, it will last for a little over 1 full day of moderate use if you disable the Always-On feature.


The 15-watt fast charger that comes with the phone will charge it from 0 to 31% in 30 minutes and from 0 to 100% in 1 hour and 45 minutes.


The Galaxy A51 does not support wireless charging so you must use a cable to charge this phone.


Samsung Galaxy A51 Performance:


The Galaxy A51 is powered by the Exynos 9611 processor and it has 4 or 6GB of RAM. This is a mid-range processor that’s equivalent to the Qualcomm Snapdragon six series.


When multitasking on the Galaxy A51 it has a tendency to lag, it’s very obvious that the phone’s processor is struggling to perform the necessary tasks.


Hopefully, this is not a deal-breaker, nevertheless, this phone comes with 128GB of internal storage.


If that’s not enough storage space you can expand the storage on this phone via a microSD card.


Samsung Galaxy A51 Worthy Alternatives:


The Galaxy A51’s best rival is the Google Pixel 3a, this is a great mid-range phone that performs very well.


The Pixel 3a has a better camera and it’s faster and more responsive than that Galaxy A51.


Last year’s Galaxy A50 is still a great option, and it can be purchased for less money since the arrival of the Galaxy A51.


Is the Galaxy A51’s minor upgrade worth the additional money over the Galaxy A50? I’m not sure?


My Final Thought:


The Galaxy A51 is a small upgrade to that of its predecessor from last year the Galaxy A50.


Nevertheless, the Galaxy A51 is a beautiful phone with a beautiful AMOLED display screen that offers great battery life.


The display screen and the battery life are the main selling points for this phone. Nevertheless, this is a decent mid-range phone that’s ideal for anyone on a budget.
