Samsung Galaxy A3 Core review: An entry-level Android phone with 4G Internet

Posted by

The Samsung A3 Core is an entry-level Android phone that costs in the range of $90. What is it like using this sub-$100 smartphone in 2021? I got my hands on one and have used it for a period and I am ready with my experience and verdict. So, come along and enjoy my Samsung Galaxy A3 Core review.


There are not a many big smartphone brands making entry-level Android phones any more. Which is understandable, because there isn’t a lot of money to be made per device. Samsung is one of the few who still do.

Samsung Galaxy A3 Core Review: Hardware And Design

I have handled scores of cheap Android phones. Many of them feel flimsy in the hand. The Samsung A3 Core is not one of them. It is a plastic phone that feels quite solid and well built. The handy size makes it a delightful phone in the hand as well.

In terms of looks, it is a little retro and has some bezels all round, but the whole package works well. Here is a phone you can hold and use comfortably without the worry that it will drop from your hand.

The Volume control and Power button are at the top section of the phone’s right side. There are no buttons on the opposite side. Instead, the dual-SIM and memory card slots are there.

There is nothing on the top edge of the phone. At the bottom are the 3.5mm audio port, microphone, micro-USB port, and loudpeaker grille.

At the back is a single 8-megapixel camera and LED flash on a textured back. If the Samsung logo counts as a design feature, it is there towards the bottom end of the back panel.

Yes; a fingerprint scanner is missing. The Samsung A3 Core does not have one.

Samsung Galaxy A3 Core Review: Software

The Samsung A3 Core runs a version of One UI, based on Android 10 (Go Edition). Going through the About phone menu, I find no mention of One UI at all. But the icons and user interface clearly scream One UI.


Being Android 10, there is the option to turn Dark mode on, which I promptly did the first few minutes of having the phone in my hands. It is mostly consistent but there are a few areas of the phone that do not have Dark mode implemented.

One was inside the Gmail Go app. I use the past tense because the version of Gmail app that came pre-installed in the Galaxy A3 Core did not change to Dark mode. However, as soon as I updated the app, voila, it went Dark. The other is the Software update page. It is still white as I type this. But I am nitpicking. That menu is obscure and will not be seen often.

Being an Android Go Edition device, all the Google apps are “Go”: versions. That means, they are the lighter versions optimised for low-hardware devices at the entry level. They are smaller, lighter, and run faster on entry-level devices like this one.

It is good to see Samsung support the Lite apps movement. They have a lite version of their web browser pre-installed (it doesn’t go dark under Dark Mode though). The pre-installed Samsung Max app is also the lite/Go version.

Along with other Google Go apps, Gboard Go comes pre-installed, but the default keyboard is Samsung’s own. It works well, but my personal preference is Gboard.

Samsung Galaxy A3 Core Review: Network And Telephony

If there is one thing I am glad to see on the Samsung A3 Core, it is the 4G LTE support. Many smartphones at this price point now lack 4G LTE. It is good to see an entry-level Android phone with 4G support.

The Samsung A3 Core holds on to a network signal well.

If you have access to Wifi, that is available on this smartphone as well. You can also connect it to the Internet via Bluetooth tethering, should you ever need to.

Auto brightness is cranky, often returning the screen to a dimmer mode than I enjoy. It isn’t the first phone this is happening with though. Eventually, I disabled it and manually fixed a brightness that works for me.


The display is good and video and audio are okay as well. Nothing out of the expected for a phone of this price.

There are no problems with telephone calls. Audio is clear as well during telephone calls.

Samsung Galaxy A3 Core Review: Photography & Video

Photography and video on a basic smartphone isn’t anything fantastic. Exceptional cameras are expensive, so you won’t find one here or in any low-end Android phone.

In dark environments, photo quality goes totally out the window and becomes trash. So, the A3 Core is not recommended for night or low-light shots. If you are lucky, you will get some good shots.

Even in well-lit settings, like bright sunny outdoors, the photos it shoots are inconsistent. I included two selfies shot at the same spot and same time below to illustrate this, but it happens with both cameras. If you buy the A3 Core, I recommend that you take multiple shots of each photo you want and pick the best results.

Samsung Galaxy A3 Core Review: Multitasking And Performance

Using an entry-level Android phone is like driving a budget city car. They are not built for speed or power. They are built to offer you the best possible experience at the lowest possible prices.

The Samsung A3 Core works well if you don’t load it up with tons of apps and fill it up with junk. Having 1GB of RAM means that app launching and switching is not zippy. It also has a low budget processor. Bear these in mind when using it and you will be fine.

Don’t push it like it is a sports car or 4WD SUV or truck, because it isn’t even close. It is a basic city car. Performance is smooth, but you will get frustrated if you load it up and try to race with it.

Samsung Galaxy A3 Core Review: Battery life

Unsurprisingly, battery life of the Samsung A3 Core is good. On a full charge, the battery runs for over two days – almost running into three. This is on a moderate use case – a few hours of web browsing, email, and the odd telephone call and SMS.

If used more intensively, it will likely not exceed 48 hours. And that is really good. Charging is regular standard, meaning there is no fast charging. Plug it in and wait for at least two hours for a full charge.It is best you leave it plugged in overnight.

Samsung Galaxy A3 Core Review: Final Words

Samsung Galaxy A3 Core is a decent entry-level Android smartphone. I love that it has support for 4G LTE, though you have to give up the fingerprint scanner. Before you start cussing, competing devices at similar price points mostly lack 4G support and have a fingerprint reader.

This is a trade-off and you have to decide what option works for you. If a fingerprint reader is more important to you than 4G, there is a catalogue of competing devices from brands like itel, TECNO, and Infinix.

Physically, the Samsung A3 Core feels like a phone that will do well against wear and tear too. For $90 or ₦33,000, depending on where you live, it isn’t a bad choice.
