Review LG G Flex 2: curved android-smartphone new generation


Previously, we have had the opportunity to meet with the predecessor of the current guest – LG G Flex. In general, from the unit left a good impression, since he won an unusual design and the presence of interesting possibilities. But there was a fixed number of shortcomings, which, apparently, fixed in the G Flex 2.

The new model was presented at CES 2015. And it became clear that thoroughly worked over it, because technically the gadget came on the current level. For example, the updated processor and software, increased display resolution, there was a slot for memory cards. It should be interesting, besides LG talk about their child because “Perhaps the best curved smartphone.”

To test this claim, let’s start consistent study G Flex 2. However, for comparison, a conventional pick curved smartphones from other manufacturers except Samsung Galaxy Round will be difficult.

The device will be available for sale in two variants: with 2 GB of RAM and 16 GB of internal storage, or 3 GB of RAM and 32 GB of internal storage. The LG officially delivered to the Russian market and, therefore, accompanied by local support. There Dark Silver (Platinum Silver) and red (Flamenco Red) body color.Presented are also several versions for different operators: LG H955 (EMEA), LG LS996 (Sprint), LG H950 (AT & T), LG US995 (US Cellular).

On our test machine Silver (H955) with 2 GB of RAM and 16 GB of ROM. The average price of this smartphone in both versions at the moment is about 25 000 rubles. LG G Flex 2 is widely represented in retail, and the model with 32 GB of permanent storage can be found even cheaper.

A detailed review of LG G Flex 2 will begin with a brief description of its specifications compared to its predecessor.

It can be seen that the smartphone has changed significantly for the better. The screen is smaller, but got a much higher pixel density, the updated filling meets 2015, there was a slot for high-capacity memory cards.Yes, LG G Flex 2 has become smaller and lighter, but the battery capacity has become smaller. But with communication capabilities is still all right.

In general specs look decent. The only question is the real quality of the product and how it all will work fine.Speaking of production LG, we are almost sure that serious problems should not be. But, nevertheless, it is necessary to verify.

Packaging equipment LG G Flex 2

Smartphone entered the test without packing and supplied. We know that it will be delivered in a compact cardboard box. It will be possible to find a standard delivery:

  • Cable USB;
  • The charger (5.0 V, 1.8 A);
  • Branded Headphones LE530;
  • Documentation.

The quality of all components of the traditional supply needs to be good. In addition to the smartphone will be available Case QuickCircle.

The look and design of LG G Flex 2

LG G Flex 2 is made in the collapsible enclosure made of plastic. All front panel holds the glass under which there is a screen. Glass markedly curved along and deepened in the center, which gives an unusual visual and tactile sensations. Few people are now trying to implement in their devices this kind of delights forms.

The rear part of the panel completely covers gray glossy plastic, issued under the polished metal. This material is fairly brand. Here, as in the first LG G Flex, uses self healing. That is fine scratches should be tightened in a short period of time. Maybe it is so, but in our instance scratch enough, both large and small.

Fringing ends made of the same smooth gray plastic only partly configured as a separate insert. Talking about the similarity with the specific models of other manufacturers is not necessary.

The housing is bent together with the screen, its thickness at its thickest location – 8.9 mm. The faces are smoothed, there is no sharp corners. The unusual shape of the smartphone touch makes itself felt very delicately.

Keep the device handy with ergonomics in general, everything is fine. And thanks to a narrow frame around the display with the average person can normally hold the hand unit.

The height of the LG G Flex 2 is 149.1 mm, width – 75.3 mm.

Review LG G Flex 2: curved android-smartphone new generation

Claimed weight of the device is 152 g (weighing confirmed this option). The smartphone feels normal for their size.

Above the screen is LED, front camera, earpiece, light sensor and proximity. The speaker is equipped with a slit medium size and is located in a convenient location.

The indicator located on the left, it is medium in size and is bright enough. It would be nice to be seen from afar and from different angles. He gently pulsing red when charging and flashes green once every 10 seconds when missed events.

Below the display there is no touch buttons. They are in this case the onscreen. Here there is only a logo and labeling, which says that our sample is not intended for sale.

The main camera is located at the top center of the rear panel. The camera module is barely above the level of the body. It must not be scratched, and the smartphone will lie flat on the table (to the extent possible, given a curved shape).

Near placed dual LED flash, laser focus and window control unit. Yes, programmable power button and volume are placed traditionally for the latest LG smartphone on the rear panel.

At the bottom of the back cover on the left is a small hole-punched for the main speaker.

On the left side there are no elements.

The right side contains only the hook to detach the rear panel.

At the bottom there is a connector USB, microphone, and opening a spoken 3.5 mm.

On the upper face are infrared and optional microphone.

The back cover is securely fastened to the latch.

Arrangement of elements below it is quite predictable. Only here until the battery is not accessible without a screwdriver.

Review LG G Flex 2: curved android-smartphone new generation

There is a connector for the Micro SIM-card and memory card MicroSD. Hot swapping of cards without removing the battery.

The quality of body parts and their good treatment. Assembled body properly when pressing and twisting crunches and squeaks no. Fit parts precise enough and dense, and the gaps are the same everywhere. In short, the whole smart phone looks nice, simple and concise.

Controls and connectors are located conveniently. The size of the buttons is sufficient to press them with a palpable and audible click. Installed sensors and sensors do not allow failures in work, the vibration motor can feel good. With the active use of the enclosure noticeably warm, but temperatures remain within the comfortable feeling.

Externally by an unusual curved shape the smartphone has turned out attractive and interesting. Premium nothing here, but it is clear that the LG G Flex 2 is not a cheap machine. If not easily soiled gloss on the back panel, then all would be well.

Display test LG G Flex 2

LG G Flex 2 is equipped with a 5.5-inch screen with a matrix of the type P-OLED with a resolution of 1920 x 1080 pixels. The pixel density of 403 ppi, aspect ratio – 16: 9. It is relevant and sufficient for the majority of people parameters.

The picture is rich and clear, colors are “juicy.” The black color is visually perceived very deep. Due to the high-resolution screen pixel density also get high. To see the structure of the image in this case is possible, but very difficult.

Visually, no serious complaints to the screen there. Let’s see what the tests show.

To get the exact data, we are usually tested smartphone screen using a colorimeter X-Rite ColorMunki Display.Let’s start with brightness and contrast:

The range of brightness is normal. When using a screen in the street, in daylight conditions, this range should suffice. It is suitable for most other scenarios. An exception may be only a complete darkness as the minimum brightness of the display is high. The contrast ratio due to peculiarities of the matrix goes to infinity.

Automatic brightness adjustment and proximity sensor are working properly.

Gamma curves customized good, deviations from the “‘s reference” is almost not expressed. The image will not have problems with saturation.

The color gamut does not conform to sRGB, there are deviations in a big way. This will affect the color reproduction.

Points are gray wedge with a small spread and far from DeltaE <10. Weak parasitic shades may be present.

The color temperature is far from ”s reference “6500K, is not very stable and is located at 8000K. The image is a little bit cold.

Color settings can be called mediocre. All channels are not very stable and are located far from each other.

The relationship between brightness and color saturation is not expressed.

The uniformity of illumination on a white background in the normal screen. The dark areas are not expressed.Is that white angles gives cool shades.

On a black background due to the nature of the matrix everything is perfect, because the black color of the screen from the true. No Glow-effect here.

The color image is not distorted and the colors are not inverted. But at angles slightly noticeable overall drop in the contrast and brightness of the image.

Results for the most part turned out normal. We get good contrast, uniform illumination and relatively accurate, some basic settings.

Based on the test results, defects in the display settings, too. For example, the temperature and the color setting is not meet the standards. But this is unlikely to be very critical, because visually it looks decent.

The screen is equipped with a protective glass Corning Gorilla Glass 3, and deprived of air gap. The sensor supports up to ten simultaneous keystrokes. He is sensitive, accurate and works flawlessly. Oleophobic coating on the screen is, and it is quite good.

Hardware platform and performance LG G Flex 2

As the processor in the LG G Flex 2 uses a Qualcomm Snapdragon MSM8994 810 with eight cores: four core Cortex-A57 plus 2.0 GHz quad-core Cortex-A53 1.5GHz. As graphics it uses Adreno 430.

This is one of the most advanced SoC at the moment that no problems can provide smooth operation of the smartphone interface and all applications.

The amount of RAM in our smart phone is 2 GB. In this case, a simple free memory is slightly less than half.RAM running at a high rate, as evidenced by test MemBench.

All tests were run compatible and tested without errors and lockups. Smartphone many of them showed very good results. But in some benchmark results were not very bright. This is probably due to the limitations of CPU performance in our particular sample.

The data obtained benchmarks can be said that applied hardware configuration will be able to provide the required performance in all applications. You can also count on the supply of power for smooth operation in demanding apps / games.

Check the stability of the device did not go very smoothly. LG G Flex 2 a couple of times during the long hang maximum load and immediately after the graphics stress test. We hope that this problem is only our sample.Casing temperature rises, but the touch is within the comfort value.

In all games, including “heavy”, the smartphone proved to be confident. All three-dimensional games on it are going smoothly and with normal frame rate per second. Failures FPS, artifacts and any other graphic distortion is not noticed. So it is suitable for games, and even be able to act as a quick game console. The filling for these tasks are quite entertaining tech and performance. In the most demanding games with well developed physical and graphical effects of difficulties also arise.

With work interface no problems noted. Menu scrolled smoothly, and delays in opening menus and launch applications are minimal. The images and pages in the browser zooms without appreciable jerks and video supported formats in high quality are played without any problems. If we talk about the feelings of the speed of the device as a whole, it is hig.

Firmware and Software LG G Flex 2

The operating system in the LG G Flex 2 uses Android 5.1.1. On top of established proprietary shell Optimus UI with lots of traditional features.


Root access on the device is closed, but problems with its reception should arise. In the web you can find instructions on this subject.

Let us turn to the interface and installed applications. Everything here, as always, diverse and abundant.

Multimedia LG G Flex 2

To view photos in the LG G Flex 2 uses a gallery with the ability to edit images.

The recorder is, and the FM-radio in this instance is not (although it should be).

As a music player, use a separate audio player with equalizer presets and. Music in MP3 and FLAC play normally, without delay.

Standard single video player suitable for normal playback of many formats, the problem with no sound decoding. Its functionality is sufficient.

It should also be said that watching the video on a curved screen for a few more pleasant than on a plane.

Videos Online reproduced without the delays and other problems.

Review LG G Flex 2: curved android-smartphone new generation

As a result, listening to radio online, and all the rest get “out of the box.”

Performance smartphone enough for video playback in most current formats, but there are some minor restrictions. That’s what showed AnTuTu Video Tester.

Complete sets because of its absence from the test could not be verified, but it should be good. When listening to the sound side of the headphones can be called normal quality. Detail and depth of sound enough frequency range reveals good.

Using different equalizer settings LG G Flex 2 could be more or less fit the music player, but the low level of -15 dB signal does not allow it to sound loud enough output 3.5 mm.

To test the sound Right Mark Audio Analyzer smartphone connected to the sound card ASUS Xonar DX (signal / noise ratio at a record 113 dB). The results were not the most interesting, which, of course, not acceptable for a smartphone of this level.

Wireless interfaces and communication LG G Flex 2

Microphone recording sound, including video and conversation behave normally. Sensitivity enough to capture the sounds of the environment and the voice. No third-party interference or distortion is not noticed.

The LG G Flex 2 has one the SIM-card format Micro. Supports standards 2G / 3G / 4G. Signal strength and speed mobile data stably maintained at a normal level smartphone. The conversation is not interrupted. To speed communication over Wi-Fi (b / g / n / ac) no complaints. The smartphone supports NFC, there are infrared.

Stated connectivity and data transfer:

  • 2G: GSM 1800, 1900, 850, 900;
  • 3G: UMTS 1900, 2100, 850;
  • 4G: LTE 1800 850.

The menu has everything you need to control the parameters of communication.


For positioning in the space module is used GPS / GLONASS. Work A-GPS allows you to find the satellites in just seconds. The device is easy to fix a large number of satellites.

Location accuracy is obtained high, and tracking the move smoother.

In Bluetooth 4.1 61.13 MB file volume is transmitted in 4.5 minutes.

Memory and file system LG G Flex 2

For storage LG G Flex 2 provides 16 GB of memory. There is a version with 32 GB of storage. The user can have about 10 GB to store personal data. Fortunately there is a slot for memory cards up to a capacity of as much as 2TB, which will very significantly expand storage.

Connection to the PC smartphone possible modes of multimedia devices (MTP), an image sending (PTP) and charging only. The data is exchanged using a standard connector USB 2.0.

Below are the test results storage benchmarks. The speed of the internal drive is high. In the implementation of the recording file in the internal memory of the smartphone speed was at least decent. Files of 613 MB copy in 30 seconds. When transferring large media files do not have to wait long.

The battery life of LG G Flex 2

LG G Flex 2 is equipped with a non-removable battery capacity of 3000 mAh. This is quite an adequate option for this machine.

Fully charged smartphone USB 3.0 can be implemented in about three and a half hours. From USB 2.0 it will be charged for about six hours. Staffing charger (5.0 V, 1.8 A) will charge it at least two hours. There is a function fast charging when the gadget receives half an hour 50% charge.

Now about offline. AnTuTu test showed normal 5513 points. This is certainly not the best result against the background of some of the devices, however, it can be called good. Under full load the smartphone lasted more than three hours.

What will PCMark? Six hours – this is a normal result.

Geekbench 3 discharge the battery for nearly four and a half hours of continuous load, which can also be called a good result.

Actual tests have shown that you can count on a relatively acceptable battery life with active use of the screen and processor smartphone (playing games, watching movies, etc.). But better still monitor the status of the battery, as some records in terms of “survivability” is not exactly the hero of the review shows.

Below for a more complete picture of the results of the calibration in the “Battery HD».

For additional savings is a simple energy-saving mode.

The smartphone is capable of autonomous operation with moderate use for eight or nine hours. Continuous operation in the three-dimensional heavy games will eat the battery in around three to four hours. Large mixed load (games, movies, web surfing) discharge its average for five or six hours. If the machine is used in the power saving mode (for example, mainly for listening to music with the screen off, but not for browsing), you can count on a full day of battery life and more.

In the same very minimal activity smartphone able to stretch for several days. The simple self-discharge and the discharge from performing basic functions in the device is not very pronounced.

Camera LG G Flex 2

The LG G Flex 2 has two cameras: the main with a resolution of 13.0 megapixels, OIS OIS +, laser autofocus and dual-LED flash and front – 2.1 megapixels.

Maximum image resolution: 4160 x 3120 and 1920 x 1080 pixels, respectively, the main video camera shoots at resolutions up to 4K (3840 x 2160 pixels). The front camera records video in Full HD resolution (1920 x 1080 pixels).

The camera interface is reduced to a minimum without compromising the strong functionality. It is simple and intuitive, while it has all the necessary settings and a set of basic elements. There is an effect, panoramic shot, HDR and so on. By the process of shooting and laser AF have no complaints, everything happens very quickly and accurately.

The functionality of the camera is shown in the pictures below.

Now it’s time to evaluate the quality of images and videos obtained with LG G Flex 2. All pictures, including pictures comparing the other cameras were obtained when shooting in auto mode, with default settings and the highest possible quality.


Unusual smartphone LG G Flex 2 can be called a very successful model of the company. First he wins the competition due to the unique design and proprietary features specific to a device LG.

It is also a technological and productive apparatus, able to solve most of the tasks that will put in front of him demanding users. Of course, without bottlenecks has not done, and a test to us was not the best copy.
