Review: LG G4 smartphone

The newest generation of the top of the South Korean company bets on a powerful camera as the main differential to conquer the consumer

The smartphone ‘s LG G2 and LG G3 are among the biggest hits from LG. Since joining the line-to-line segment, the South Korean company has been more pleased than it has disappointed its customers, revealing models with quality hardware coupled with a competitive end price .

And as the saying goes that in the winning team does not move, LG decided to keep many elements of its predecessors, updating only the hardware and bringing news related to the camera software . Incidentally, the rear camera is the flagship of the new LG G4 , especially because of the extensive manual control of image capture.

Since April 28, when the device was announced in New York, in the United States, Info Digital had access to first hand a copy of the mobile phone , kindly provided by LG. It’s time to confer an analysisdetailed with all the news of LG G4 . Is it worth investing your money in it?

For those who see from a distance, the LG G3 and LG G4 may look like the same handset. The company chose to maintain a look very similar to that of the predecessor, especially the fact that the LG G3 pleased consumers greatly when it was released. The main novelty of the company in this question was reserved for the finishing.

Design LG G4

More refined on the sides, the LG G4 arrives in international stores with nine finishing options. There are six of them with the leather back cover, in the colors brown, black, red, yellow, blue and beige; And another three with plastic back cover in gray, white and gold. In Brazil, only four of these nine versions will be available: brown leather back cover and gray, white and gold plastic back cover.

The leather back cover, undoubtedly, is the one that draws the most attention. Its construction is plastic like the others, but the carcass has a real leather coating. The G4 logo can be seen in the lower corner in low relief and a seam cuts vertically the middle of the product. The version with the plastic back cover has a low relief texture, with squares arranged diagonally, revealing a modern look.

The leather finish is the main novelty in terms of design

The LG G4 does not have any type of certification that makes it resistant to water or dust, so nothing to wet the device. The back cover remains removable and the power buttons and volume controls remain on the back of the product. In terms of design lines, the screen has gained a slight curvature, which makes the footprint more anatomical. As a result, the device fits better on the face during the connections.

Anyone who already owns an LG G3 will surely notice the subtle differences between the two handsets. However, those who were expecting more drastic changes will be disappointed. Still, despite the similarities, the LG G4 manages to show its personality in some finishing details and shows itself a nice cell phone for handling.

Compared to Apple and Samsung, the difference in philosophy chosen by LG with regard to the construction of the device is clear. The materials selected in G4 do not use aluminum and glass in the rear. Instead, the company opts for legitimate high-quality handmade leather in a handcrafted process that takes up to 12 weeks to complete after undergoing various durability treatments.

This process, for example, takes up to 10 times more than the conventional 4-day process to make a plastic back cover. It is a more human, artistic appeal, as if it were a painting. LG itself expects every G4 to gain a unique look over time.

To perform this analysis , we submitted the LG G4 to five benchmark applications. They are: 3D Mark (Ice Storm Unlimited), AnTuTu Benchmark 5, Basemark X, GFX Bench (T-Rex HD Offscreen) and Vellamo Mobile Benchmark (HTML5 and Metal).

In the tests, the device did well, obtaining numbers above those conquered by the models of the past generation. However, as expected, the LG G4 ‘s six-core processor lost in absolute numbers to some competitors whose chip architectures are eight-core, which in no way means its performance is poor. Check out the comparative charts in each of the tests.

The new generation of smartphones arriving in the market in 2015 brings with it an interesting feature: all new gadgets, without exception, will be able to run with ease everything that is available in the Play Store. This scenario should lead to the following situation: in practice, performance will no longer be a fundamental item.

The LG G4 is no different. In absolute terms of processing, it stays below the Galaxy S6, for example, but this in no way can be considered a problem. In our performance tests, the device ran absolutely everything we tested, with no crashes or some kind of slowness to open applications.

The hardware of the LG G4 is not more powerful than the Galaxy S6, but both run everything with great tranquility

Games that require greater graphics processing capacity, in addition to movies and series via Netflix, have run smoothly and smoothly. Using social networks and messengers, the result was no different. The Snapdragon 808 chipset is quite balanced, ensuring the power required and heating very little during its operation.

Along with 3 GB of RAM, the set is responsible for ensuring that everything flows naturally. RAM consumption rarely exceeds 2 GB, which makes the hardware more than adequate for all tasks. Regarding the LG G3, the evolution is clear, but again it is necessary to mention: even G3 is capable of performing well all the functions to which it is submitted.

In practice, if you are looking for more performance, trading the LG G3 with the LG G4 may not justify the investment. There is progress, but it is possible that the cost-benefit ratio will not ultimately pay off.


Although the LG G4 display has exactly the same screen size as the LG G3 – 5.5 inches – and the resolution is also the same – 2560×1440 pixels – there are significant changes in display construction that directly affect the user viewing experience .

What’s new is the Quantum IPS technology, which provides images with up to 20{890c36218bbc94bcbe8f5d159f212155cbf0c932418a12ec06828c4a996999c1} brighter and almost 50{890c36218bbc94bcbe8f5d159f212155cbf0c932418a12ec06828c4a996999c1} more noticeable contrast. The new model from LG offers a 98{890c36218bbc94bcbe8f5d159f212155cbf0c932418a12ec06828c4a996999c1} standard color spectrum DCI (Digital Cinema Initiatives), something close to what is seen in Hollywood movies. With more saturations in red and blue tones, the result brings visually more “dimensional” images, which provide an above-average viewing experience.

The construction technology used in the LCD array also has new features. Basically, in traditional displays the light is diffused or blocked thanks to polarized liquid crystals, through an electric field created by electrodes at the vertical ends.

In G4, this process happens at the horizontal ends, which increases the accuracy of the light control. With this, this layer becomes more uniform and more light passes, also decreasing the power employed. In other words, you have more brightness with lower energy consumption, since there is less light wasted in the process.

The result of the LG display is the best possible in both the display of photos and the time to check videos in high resolution. If what you saw in the LG G3 was already very good, imagine that what can be viewed on the LG G4 is even better, whether in dark or extremely bright environments. Undoubtedly, one of the most striking aspects of this generation of top of the line LG.


Unlike Samsung, LG chose to keep the battery of the LG G4 removable. The capacity is exactly the same, ie, 3000 mAh. In practical terms, the user should find similar results with regard to the duration of charge compared to LG G3.

There have been improvements in manageability via software, the screen now consumes less and the new chipset also needs less power to produce more. In this way, we have a more powerful device with a relatively lower consumption.

The LG G4 is more powerful, but requires less power
to do heavier tasks

For those who use the cell phone moderately, it means the battery can last for more than a day very easily. For those who stress the device with a more intense use, it is possible to reach the end of the day with a little load. In this way, we can consider performance quite satisfactory.

The downside in this case is the lack of Qualcomm’s Quick Charge technology, meaning no recharge of the battery extremely quickly. However, even without this feature, the performance is above average when compared to other models that also do not adopt the fast load as a differential. The wireless recharge mode remains unchanged.

View Profile

The version of the LG G4 received by Info Digital for analysis is exclusive to the vehicles of communication and, therefore, it may be that the final set of items does not exactly match what consumers will receive at the time of purchase. This is the case of headphones, for example, since this version we receive does not have this accessory.

The audio quality of the device itself does not disappoint. The speaker is located on the back of the product, but because of its positioning, the audio output is rarely covered with hands. The sound emitted by the smartphone is not one of the highest, but it is solid and has low noise, which makes it quite functional in this regard.

LG G4 Camera


Among all the updates that the LG G4 received, no doubt the rear camera is the aspect that gained the most attention from the company. During the presentation of the product, much of the time was spent explaining the new camera functions , features that turned the device into a true “cameraphone” of this generation.

One of the tools is the color spectrum sensor. It can be seen on the back of the device just below the LED flash. But what exactly does this do and what benefits does it include in the final result of the images? The most significant improvement is the fact that the new sensor is capable of capturing more natural shades of color.

Its function is to measure ambient light and determine the exact source of light in the context in which you are, whether natural or artificial. The company also guarantees that the sensor can more accurately identify the differences between light and objects. Knowing the exact light condition, the software is easier to determine the appropriate white balance for each situation.

This feature is seen as one of the key points for a photo to be displayed in a balanced way. The Color Spectrum Sensor (CSS) improves the reading of the RGB tones of a scene, as well as more accurately interprets the light reflected by objects from the infrared sensor.

Manual controls expand user possibilities, but you need to have some photo knowledge to take advantage of

The rear camera has a 1 / 2.6 “16-megapixel sensor, which allows images with dimensions of 5312×2988 pixels. In addition to color spectrum sensors, three other features help capture good photos: dual-LED flash, three-axis optical image stabilizer, and laser focus.

In addition, it is possible to access manual controls of shooting modes, which makes it much more professional and artistic possibilities and their captures. The idea is to make the mobile phone experience closer to that view on the DSLR camera .

Another highlight is the aperture of the camera , f / 1.8 – the largest among mobile phones is already launched. This feature allows you to capture photos at a higher speed with more clarity. In addition, photos in nighttime environments tend to get better because of the increased incidence of light. Learn about the LG G4 manual photo controls .

Front camera : the evolution of selfies

It was not only the rear camera that gained special attention from the manufacturer. The front-end camera , increasingly popular because of selfies, has reached 8 megapixel resolution in the LG G4 – the largest among models available today.

The Quick Selfie feature, in which you simply open and close your hand in front of the camera to activate the shot, remains present. However, there is an interesting novelty for those more perfectionists. If you do this same motion twice in a row, the camera is fired four times, allowing you to choose the best picture from the available options.

Selfie with the LG G4



There are no significant visual changes in the LG G4 software . Utilizing version 5.1 of Android, the company opted only to refine icons and menus, leaving the style even more in tune with the Material Design line deployed in Lollipop. Compared to other company releases , there are fewer embedded software and almost no duplicity of applications (there is only one native browser instead of two, for example).

It is still possible to use the cell phone as a remote control of the TV, and of even novelty there is a package of icons that allows direct shortcut to control functions of battery and storage of the cell phone . Sliding the fingers to the right, the last screen reveals a quick access to the Smart Bulletin, a kind of central with entrance door for all the software that the company includes in the cellular .

LG G4 Interface

In it comes the Smart Settings feature, which allows you to enable some predefined settings, making the phone adapt to the environment in which you are. You can set, for example, that when connecting to the WiFi in your home, the sound profile of the device changes. These are small adjustments that, once configured, reduce your need to perform actions with the cell phone .

Worth it?

The LG G4 is not the most powerful top-of-the-line on the market. Certainly it is also not the product that will bring more innovations in this generation. However, we can still qualify the company’s smartphone as one of the most competent alternatives that consumers will have access to in 2015. Its main merit lies not only in maintaining what was already working in the LG G3, but also in the fact that Most of the items have been perfected.

Nexus 6 with the box

At the time of publication of this analysis , LG has not yet disclosed the price official LG G4 in Brazil. Therefore, it is difficult to make any analysis as regards the cost-benefit ratio of the product. However, we will update our opinion as soon as the value and date are confirmed on May 28th. Even so, most of the questions can already be explored in our verdict.

The first one is that the LG G4 is much more update than a new generation of the product (unlike what happened in the Galaxy S6). So, switching the LG G3 for LG G4 , for example, is something that is justified only by the preciosity of those who intend to have a better camera or still keep up to date with cutting-edge hardware. Both the previous generation and this new one give the message quietly to run any application available in the Play Store.

With new technologies, the screen still shows more quality than the cutting edge LG G3. Its main highlight is even the camera and photography software that have gained a large number of features, allowing greater control over the photos and providing simple and affordable usability. Without a doubt this is one of the best camera s already seen on smartphones , especially in low light conditions.

The LG G4 is not a monster in performance, but it certainly meets the needs of multiple user profiles, especially for those who love photography. Undoubtedly, the device enters the list of most wanted in 2015 and is worth investing in if you are considering a new top of the line. However, this is only justified if your final price is more attractive than your competitors, something we will know on the 28th and we will update in this field.


You ask, and Info Digital responds

1 – Does the LG G4 smartphone have a biometric sensor?

No, the LG smartphone does not have this kind of technology.

2 – Does the LG G4 have any certification that makes it resistant to water or dust?

No, the LG G4 is not resistant to water or dust. In fact, the company never bet on handsets with this type of certification.

3 – Is it worth leaving the LG G3 for an LG G4 ?

The most significant developments are in the camera and in processing speed. However, the LG G3 is still capable of running virtually everything that is available in the Play Store so far. Unless you ask too much, switching to each other for the time being is dispensable.

4 – Does the IPS Quantum screen bring improvements over the LG G3?

Yes. Although the screen size (5.5 inches) and the resolution (2560×1440 pixels) are the same, the IPS Quantum technology provides images with brighter and more contrasting colors. The difference is significant and can be easily noticed when you place the two devices side by side.

5 – Does the LG G4 get too hot?

In our tests, at no time did we get the feeling that the phone warmed up more than normal. In LG G3 this phenomenon happened eventually, especially after a few months of use. However, in the weeks that we get with the LG G4 , we do not realize something to that effect. A good point for choosing Snapdragon 808 instead of 810.

6 – Does the LG G4 support two SIM cards?

No, the LG G4 supports only one SIM card.

7 – Does the LG G4 have FM Radio and TV?

No, the LG G4 has no FM Radio or Digital TV app as well as Galaxy S6.
