Quickly I think the most amazing part of this device is its Super Amoled Display coupled with the Exynos micro processor.


In summary the Key Specs

SCREEN = 6.5" 1080 x 2400 pixels

WEIGHT = 180 g

MAIN CAMERA = 48MP 108)p

PLATFORM = Android 10.0, Android OneUI 2.0

RAM = 4/6/8 GB RAM

STORAGE = 64/128GB

CHIPSET = Exynos 9611 Octa-core processor

BATTERY SIZE = 4000 mAh Li-Po



Sincerely speaking the large display of this device added beauty to it. It has a giant 6.5 inch Super AMOLED capacitive touchscreen with the capability of displaying 16M colors This screen size is wide enough to carry out any task that is screen reliant smoothly and clearly without hitches whatsoever. And guys in 2020 screen sizes is not the problem any longer as almost all OEMs have embraced the large screen size ideas.

Most importantly is the ability of Samsung to be able to set this device at an approximately 88% screen-to-body ratio, making this devices bezel to be minimal with just a 12% fraction. It is an incredible design from Samsung.

The screen resolution is the well-known 1080 x 2400 pixels that suits the large display embedded into this phone along with a 405 ppi density.

Furthermore in its ranks of display is one of the undisputable best displays you could get on any category of smartphones worldwide. The Super Amoled Screen display which is quite expensive but clearer and attractive to be looked upon. Listen, I did not say just Amoled, But SUPER AMOLED DISPLAY. I can tell you plainly that once an individual is used to an Amoled screen displays, It could be difficult for the individual to switch to other kinds of display. Lets say LCD displays.

Based on this you could expect quite a high price on this device not because of any other factor but reasons due to the Super Amoled screen used. And please try to protect your device’s screen because if it peradventure develop any screen fault, then prepare to cough out about N50,000 in Nigeria for this screen. That’s how expensive it is.

Corning Gorilla Glass 3 was used as a shield and protection on this screen. I would have expected Samsung to do better in this expect when Xiaomi devices are busy debuting with Corning Gorilla Glass 5 not only in the front but at the back also. But at least there is a bit of a protection.

My remarks on this screen is very simple. It is excellent, beating almost all devices in its ranks.


Samsung are in the habit of switching chipsets on their smartphones especially the global variants. They sometimes use their own Exynos chipset and often times uses the Snapdragon chipsets, reasons best known to them though.


But in all either of the brands chipset is good and should be reckon with when compared to others. The Exynos 9611 chipset is said to utilises the same 10nm process as its predecessor which in terms of power efficiency is not really the best. It comes fabricated with four Cortex A73 cores with a maximum clock speed of 2.3GHz as well as four Cortex A53 cores clocked at 1.7GHz maximum all under the central processing unit known as the CPU, in a 64-bit octa-core processor arrangement. The has a graphics processor called the Mali G72 which is mostly responsible for hard tasks like gaming and so on.

Most people are busy comparing this processor with the likes of Xiaomi Redmi Note 9S and 9 pro Snapdragon 720G, but they are wrong because its functions and capabilities outweighs that of the Exynos 9611 by far. We could only compare this chipset with the Snapdragon 665 used on Redmi Note 8  a year ago.

 Although its efficiency level surpasses that of SD 665 by 5% points only. So you can see that they are almost the same. Also in terms of power efficiency the semi conductor chipset is 1nm smaller meaning their power consumption is almost but just the same.

My verdict on this device in terms of chipset performance is that you could pick Redmi Note 8   over this or vice versa expect if you will be selecting based on screen display type or probably a larger screen.

In terms of comparisons side by side Redmi Note 8  and Samsung A51  speed and performance were just equal. But I will leave this comparison issue fully in my next article. Do check back.


Internal Storage: In the storage department, this Samsung A51  comes with multiple or different variants. These include the 64GB and 128GB variants. These are the basic storage requirements on an android device and users should have no reason to worry due to the fact that the phone also has a dedicated SD card slot for and addition or extension of the storage facility.

RAM: It has almost three different RAM configurations, these include 4GB, 6GB and 8GB with different internal memory configurations. The one easily seen in Nigeria is the 128GB 4GB RAM.


128GB 4GB RAM,

128GB 6GB RAM,


The device also has a UFS 2.0 technology which enhances high speed data reading and transfer from this device to either a computer or reading data from SD cards.

Guys, a Li-Po 4000 mAh, non-removable battery is the power source or shall I say power bank supporting this great device. The same battery size used on Redmi Note 8. This should serve in its own ranks as usual. But do not expect an all day standby support if you are a heavy user. Because these batteries these days tends to disappoint. With a 6.5 inch display and a SUPER AMOLED display, guys expect battery draining on this device because all these requires power to maintain.

From user experience point of view it lasted about 12 hours of continuous uninterrupted heavy usage. Mind you minus game play. During gamin this phone was able to serve me for 6 hours of online gaming such as PES 2020 and PUGB at least you know the rest. 

Still in this department, I have to speak on the charging speed. Samsung A51  is capable of Charging fast capped at 15W maximum while the Redmi Note 8   charges at 18W maximum but with a 10W charger out of the box though.

As a moderate user this device is a great one and a prospective user doesn’t have to think twice in some aspect before accepting the terms of the phone.


THE REAR CAMERA: Guys this is not the official article where I compare this Samsung A51  to Redmi Note 8  but in summary I would like to say that when you see this Samsung device, in a way you have seen the Redmi Note 8  also.

The rear camera setup are arranged in an L-shaped format with the LED flash in between. They are Quad camera setup as follows; 48 MP, which is responsible for covering (wide) areas producing one of the best photos. 12 MP, at 123˚ (ultrawide) angle coverage which is as good as anything. Then you have the 5 MP, for macro photo and the last 5 MP, for depth sensing. It Features a LED flash, panorama mode and an HDR output. In terms of Video, it supports a 4K@30fps, 1080p@30/120fps and a  gyro-EIS.



The front facing camera is a Single 32 MP camera generous enough to be used as a selfie camera. It performs the regular wide functions when taking photos. It also features and HDR with a Video recording feature set at 1080p@30fps.

I was really impressed with the camera sample photos taken before now and I can tell you that they were as sharp as you can think. Thanks to one of the best android UI called the oneUI.

Sincerely speaking I love phones with almost no bazels, and this device promises that. The design of the body is absolutely premium in nature and cannot be under rated. It has a dimensions of 158.5 x 73.6 x 7.9 mm  that is (6.24 x 2.90 x 0.31 in) in size. It has a weight of about 172 g without casing which later increased to about 180 g with a case attached. As earlier mentioned the screen is protected with a Corning Gorilla Glass 3, a plastic back and a plastic frame. I don’t really like the plastic used on the back but on the frame it is manageable. So there you have it in terms of body build.



This phone is currently operating under the Android operating system called Android 10 with a customize One UI 2.1.  One of the best UI around which has almost a perfect optimization along with a smooth performance capabilities attached. As a user, you could expect a monthly system update and possibly an entire Android upgrade as it is with the trend with Samsung company.  


Samsung A51  supports the following technology, GSM, HSPA and  LTE. 2G bands has dual-SIM model only. 3G HSDPA supports bands like the  850 / 900 / 1900 / 2100 And the 4G bands 1, 2, 3, 4, 5, 7, 8, 12, 13, 17, 20, 26, 28, 38, 40, 41, 66 which Nigeria Networks supports.

Other connectivity include the WLAN Wi-Fi, hotspot, Bluetooth 5.0, a GPS support, with A-GPS, GLONASS, GALILEO and BDS. Others include the availability of NFC, an FM radio and a USB 2.0, Type-C 1.0 with a  reversible connector, USB On-The-Go.


There is a Fingerprint sensor  (under display, optical sensor) that is very fast in responding, it is the most secured form of security you could get. But being an under display most times it was failing to read data. Other options of security include the pattern, password, pin and face recognition. It also has a typing accelerometer, gyro, proximity, compass.

Whichever colours you decided on picking it is alright. The colours in question include Prism Crush Black, Prism Crush White, Prism Crush Blue, Prism Crush Pink. So there they are folks.



The current price for the 4gGB RAM, 128GB ROM variant is N122, 000 in Nigeria. That is a very hug price to say the least guys. But I believe that this price point is due to the SUPER AMOLED DISPLAY attached to this device.


This device is being sold in many outlet in Nigeria, but you can from the comfort of your home purchase this device from Jumia Here  or Konga Here  online malls And would be delivered to your doorstep.


My final verdict on this device is that up to the price everything was good. But the price might tip potential suitors off. But I wont totally blame Samsung because of the SUPER AMOLED display used on this device, it has to be expensive but I feel they could have done better in terms of price.

So there you have it. A great Samsung A51  device with its own unique calibrations and features.
