  • Android 7.0 Nougat

We start from the design of this smartphone firstly because you won’t be interested to see what is inside without checking the cover or appearance first.

Basically, this phone has larger dimensions than the predecessor. The dimensions are 140.7 x 70.1 x 8.6 mm, which is a medium size of smartphone in the class.

Meanwhile, this large size doesn’t need larger weight. Instead, it is only boasting 5.22 oz or 148 gram now. Yeah, people just praise this lightweight phone because it is kind of a direct answer from Samsung to prove that it listens to its customers. The black color adds more elegant feelings to the owners of the phone.


Talking about the display, Samsung gives the J3 Luna Pro with a 5.0-inch display that can provide 720 x 1280 pixels. Other cool features are scratch-resistant glass, ambient light sensor and proximity sensor. Those features can be found on its display.


In addition, the latest operating system, Android 7.0 Nougat, is already available on this Samsung Galaxy J3 Luna Pro. Of course, it is such good news for entry-level class because we got the OS that we really need these days.

However, the same user interface of the predecessor is still here. Yes, it is the favorite UI of Samsung called Samsung Experience.


The camera of the Samsung Galaxy J3 Luna Pro is kind of disappointing, and it is one of the cons that we found from the users right now. The low resolution camera just doesn’t suit with the specs of this phone.

It is only 5 megapixels camera. Some hardware like autofocus, LED, and F1.9 aperture size isn’t enough to make a satisfying camera moment for the users.

But, the camcorder features have 1920×1080 (1080 HD) output already. It can provide 30 fps for video calling and sharing.

Meanwhile, the front-facing camera that you need to use for selfie is only 2 megapixels. The camera of the phone is just like minor change of its predecessor.


The performance of Samsung Galaxy J3 Luna Pro is outstanding among other entry-level smartphone. Thanks to the Quad-core 1.4 GHz, ARM Cortex-A53 64-bit processor, that brings this phone above the average level on its performance.

Moreover, Samsung gives us Qualcomm Snapdragon 425 MSM8917 to provide better specifications. The graphic is supported by Adreno 308.

The complaints come from the memory RAM and built-in storage of J3 Luna Pro, which are pretty disappointing for some users. You have to struggle with its 1.5 GB RAM. This RAM is only best for medium class of smartphone.

Meanwhile, the built-in storage is also standard among other smartphone. You can upgrade the storage expansion by the way up to 256 GB, though. But, you need extra budget for that.


You must be proud with the connectivity of this phone because it contains 4G LTE data connection as the primary SIM.

Everything you need for the connectivity exists on the phone such as Bluetooth v4.2, Wi-Fi, USB 2.0, GPS, and many more that enhance your connectivity.


The battery is still 2600 mAh, which comes standard in the class. This is a replaceable battery with Li-ion feature. If you use this phone for talking and communicating with others, it is able to stay for 20 hours.

If you keep it at stand-by mode, it will stay for 16 days. You can use it with LTE internet for 12 hours. The Wi-Fi time is also longer because you can use with 13 hours.


To wrap this Samsung Galaxy J3 Luna Pro review up, you can rely on the phone when you need something light on your hand and in your pocket.

People just disappoint with the rear camera and RAM size. If you don’t really get into photography, this phone will suit with your daily activity.
