Software

The LG K31 Rebel has the major software characteristics of a performant smartphone. It has the Android 10 (Android Q) Operating System installed in it. It also incorporates pre-installed software like:

  • Navigation Software.
  • Voice Command Software.
  • Face Recognition Software.
  • Personal Intelligent Virtual Assistant.

CPU & GPU

In terms of CPU and GPU, the LG K31 Rebel really packs a punch, which is really surprising for a smartphone with such a modest price.

This phone has a 2000 MHz processing frequency, which is delivered by a 12 nm Arm Cortex-A53 octa-core 64-bit processor. It also uses an IMG PowerVR GE8320 as its GPU, which is actually quite good at handling highly demanding mobile games.

RAM & STORAGE

Throwing an eye at the RAM, the LG K31 Rebel has an LPDDR3 SDRAM chip with a size of 2 GB.

As for the Storage capacity, the LG K31 has 32 GB of disk capacity. While it has quite good internal storage capacity, not all of it is usable. The phone will permit you to use only about 17 GB of internal storage.

At this point in time you may be thinking that the storage may be one of the downs of this phone, but no, it is not much of a big deal.

Actually you can solve the storage problem by buying a relatively cheap microSDXC. The phone supports storage capacity expansion using micro SD cards of up to 32 GB.

Display

Talking about probably the most important part of the LG K31 Rebel’s hardware, we are going to be taking a closer look at this phone’s pixel density and resolution.

The display area used by the LG K31 Rebel is about 77.1% of its display area, which is quite high, considering the average display area usage is about 70%. This gives room for more content to be displayed and interacted with, on the screen.

The LG K31 Rebel’s display technology type is an IPS LCD. It has a display size of 5.7 inches. Its resolution is 1520 x 720 pixels (Full HD) and finally, its screen ratio is 19:9, its pixel density of 295 PPI.

From the above specifications, you can see that it has a screen which is more oriented towards providing a great user experience. The screen provides the user with a good video and image experience, with it’s high pixel density and Full HD resolution.

Audio System of the LG K31 Rebel

Looking at the audio system of the LG K31 Rebel, it has a stereo microphone, mono loudspeakers and 3.5 mm jack audio output. It also has an additional microphone which filters out noise.

Specific Absorption Rate [SAR]

The LG K31 Rebel has a SAR head of 0.47 W/kg, a SAR body of 0.91 W/kg, a Simultaneous Transmission SAR of 1.26 W/kg and a hotspot SAR of 1.02 W/kg.

In general, the lower the specific absorption rate, the better it is for human health. Taking into consideration the SAR of this phone, we see that this phone has an acceptable SAR for head, body, transmission and hotspot.

The specific absorption rate is a quite broad and complicated topic, which we are not going be looking at in detail, but you can always get more understanding of it here.

Navigation System

The LG K31 Rebel has a simple navigation system incorporated within it. It possesses a GPS and an A-GPS. Well, this is to be expected from all modern phones, so, nothing much to say under this section.

Camera

The camera prowess of this phone excels, with a rear dual camera of 13.0 MP, a pixel size of 1.12 micrometres, an aperture of F1.8 and a sensor size of 1/3″.

It has a Full HD video recording capability, precisely 1920 x 1080 resolution at 30 frames per seconds.

It also has a front camera which can produce up to 5.0 MP of image quality with Full HD standards of 1920 x 1080.

The back camera is just okay in terms of image capturing prowess, but the front camera is just too poor, for a phone of this quality.

Even though the manufacturers decided to balance the weak pixelling of the front camera with a high resolution, the results are still not convincing.

Connectivity

The LG k31 Rebel can be used in both urban and remote areas of many countries, as it supports most of the preferred cellular bands of many companies in many countries. It supports the following connectivity specifications.

  • Bands 2(1900)
