Starting with the V10 in 2015, it is the 2016 model and the second model of the V series, LG Electronics' Android flagship smartphone series, which was released for the purpose of strengthening the premium phablet smartphone lineup. It was released on September 7, 2016 in Seoul, Korea and in New York, USA.
The overall design looks like the previous V10 combined with the G5. Based on the V10's specifications, shape and structure, the G5's rear dual camera was introduced, the volume button was moved to the side, and the power button was mounted on the bottom of the rear camera. In addition, the G5's metallic style was applied, reflecting the fact that G5 wasn't a real metal material using primers and reflecting a bad story about surface durability. It is also about 20g lighter than its predecessor, the V10. The basic colors are titanium, silver, and pink.
The specification first uses the Qualcomm Snapdragon 820 MSM8996 as its AP. The Qualcomm Kryo is split into two clusters of dual-core CPUs, forming a large cluster with high clock settings on one side and a small cluster with low clock settings on the other, quad core CPU and Qualcomm Adreno with HMP mode with big.LITTLE solution. It uses a 530 GPU. It is equipped with the same AP as the G5.
RAM is LPDDR4 SDRAM and 4 GB. The internal memory uses the NFS flash of the UFS 2.0 specification and is divided into 32 GB and 64 GB. In addition, capacity can be expanded with a micro SD card.
The display supports 5.7-inch WQHD resolution and the panel format is IPS Quantum Display based on IPS TFT-LCD. Also, like the previous one, the second screen is applied, and the second screen is applied at the top with 2.1 inches of 160 x 1040 resolution.
Supported LTE levels are Cat.12 and 13, with downloads up to 600 Mbps with Cat.12 and uploads with Cat.13 up to 150 Mbps.
The battery capacity is removable 3,200 mAh. It is said to have increased by about 200 mAh compared to its predecessor, V10, and solved the problem of battery deprivation of its predecessor, V10, and improved battery efficiency by about 20%. As the trend of the smartphone market is already adopting the built-in battery structure, LG Electronics is pushing the removable battery structure, and the identity of LG Electronics is gradually becoming its own. [7] The removable battery structure uses a method of opening the rear cover by pressing a separate button instead of removing the rear cover. The Qualcomm Snapdragon 820 MSM8996 also supports Qualcomm Quick Charge 3.0 high-speed charging technology. However, the charger provided basically satisfies the Qualcomm Quick Charge 2.0 specification.
The rear camera is equipped with a 16-megapixel camera of the Sony Xmore IMX298 sensor as a basic camera with 78 degrees of view angle and a 8-megapixel camera with a wide angle camera of 135 degrees in a wide-angle camera. Configured the lens. The base camera also supports phase detection AF and is equipped with an additional LASER AF sensor. Contrast AF is also supported, and the set is fused and named Hybrid AF. In addition, the sensor size is 1 / 2.8 inches for the main camera, and the aperture brightness is F / 1.8 for the main camera and F / 2.4 for the wide-angle camera. The maximum pixel count or camera configuration is the same as the G5, but the sensor ratio has been changed from 16: 9 to 4: 3 ratio [8], so the camera seems to have been completely replaced in the hardware part compared to the G5. Unlike the previous V10, the front camera has a single-lens structure with a 5-megapixel camera set at an angle of view of 135 degrees. In addition, the aperture brightness is F / 1.9.
Terminal type uses USB Type-C as input / output terminal and it supports up to USB 3.1 Gen1 as transmission standard [9]. It also has a 3.5mm terminal for sound output.
An area-type fingerprint sensor is mounted on the rear power button. It is also certified by the US Army's MIL-STD-810G.
Android 7.0 was built by default. At the time of release, the operating system version is 7.0. For reference, even though it is not a smartphone that Google has led to in development, it is equipped with Android 7.0 Nougat by default.
Second screen
This is the identity of the V series, which is not much different from its predecessor, the V10. When the display is active, you can use your favorite applications, multitasking, etc. When the display is disabled, you can use Always On Display. The signature feature or quick tool mode can be used with or without the display active. In particular, compared to the second screen of the previous V10 and Always On Display of the G5, the brightness is much higher.
This function marks the object in focus and tells you where it is in focus. It can be activated when using the manual focus function in expert mode. It's a feature that's not well known, and the community is responding to the usual marketing mistakes.
This is not a function that can not be implemented in existing smartphones because it works with contrast detection at first, but it can be interpreted to mean that various areas are cared for for various user experiences in that it is provided with the basic camera application. It's a good thing to try.
High quality recording
It's called Hi-Fi Video Recording, which allows recording at 24-bit / 48 kHz uncompressed. Up to 132 dB can be recorded, and the device's dual microphones support modes such as overall optimization, music (performance) optimization, and dialogue optimization for recording with the best sound quality in each environment. In addition, recording applications support up to 24-bit / 192 kHz for FLAC lossless compression, while in expert mode you can set gain, low pass filters, and limiters.
Enhanced support for high impedance acoustics
When connecting a sound device [10] with an impedance of 50 Ω or more to the 3.5 mm terminal, the 'Expert Mode' is automatically activated to boost the output from the built-in amplifier. For this reason, there is also a way to activate the expert mode by connecting an additional resistor to the 3.5 mm terminal (...), but the output is rising but not the sound quality. As the output improves, the tone is changed and the tone increases as the tone increases. As a result, DAP and amplifier can be solved in one
However, it is difficult to say that the expert mode is a panacea, because some of the disadvantages of the impedance increase, such as the sound that is eaten out of the output, may be greater than the gain from the enhanced output depending on the tone characteristics of the earphones and headphones used. For this reason, it is said that external sound outputs such as earphones are connected after connecting a non-resistance jack to the 3.5 mm terminal to enter the expert mode without changing the impedance value. In addition, battery consumption also depends on whether or not the expert mode is enabled, which is the same level as the previous V10. At the same time, the battery consumption is less.
As of September 2016, the DAC chipset [11] of ultra high performance was installed to differentiate it from competitor's smartphones by hardware function. In particular, it does not have a general DAC, but a quad DAC, ESS Saber ES9218, to enhance the basic hardware. This is the first example of a quad DAC in a smartphone. ESS's Saber ES9218 is an ultra-high performance DAC, typically used in high-performance Blu-ray px-layers and high-quality audio equipment, supporting up to 32-bit / 384 kHz and having a low noise performance of -120 dB [12].
The ESS Saber ES9218 performs oversampling and delta sigma modulation in the process of converting digitally stored information into analog waveforms, during which quantization noise [13] enters the signal. To further reduce this noise, four DACs are used in parallel to sum the average of each result [14]. As a result, the noise is canceled to add up to about -12 dB (about 1/4). It can be suppressed. In addition, only one is operated to save power. Other advanced features include analog volume.
SCL measurements were measured at a high level and, due to the nature of smartphones, they have a weaker output and offer greater benefits when using low impedance earphones with levels from 16 Ω to 32 Ω than using high impedance headphones. However, it is pointed out that some measurement values are lower than the case of using the G5's extension module Hi-Fi Plus with B & O PLAY. Crosstalk was criticized for showing less performance than Hi-Fi Plus with B & O PLAY.
However, since Hi-Fi quad DAC mode exists separately, it must be activated before it can be used. Otherwise, the Qualcomm Snapdragon 820 MSM8996's optional DAC, the Qualcomm WCD9335, will be used. When playing a normal 320 kbps mp3 file, there is no difference, but there is a difference in the sense of sound quality when playing a FLAC lossless sound source.
As a side note, the music playback stoppage that occurred when using high-resistance headphones, especially external resistors, which was a problem with the previous V10, was solved, and excessive heat generation when playing DSD / 24-bit sound sources was solved.
In some regions, LG Electronics has released a device that incorporates the tuning technology of Bang & Olufsen, so LG Electronics has developed a bundle earphone for it in cooperation with Bang & Olufsen. By default, only some regional models are built into the box packaging. In addition, although individual sales are conducted, general sales are not officially conducted because they are sold only to the device openers according to the Korean market. However, in some countries and regions, they do not provide or sell. The warranty period is one year, and the country of origin is unknown, but it is most likely produced in Vietnam when it is assumed to be an earphone cable. [16]
LG Electronics and the high-end brand of luxury sound equipment, which emphasized and emphasized the high band high quality sound source playback function and the mid and high clarity and separation in the V series, express the value of medium and high tone in a pleasant way. There is a view that the technology that makes 'sounds easier to hear' rather than 'sounds' was that it was possible to collaborate with the two companies. In fact, these parts have great strengths in earphone performance. In addition, Bang & Olufsen also lacked digital software and hardware design technology, unlike high-resolution audio market, [17]. There is an opinion that in the difficult reality, cooperation with LG Electronics will make up for the shortcomings.
The predecessor, the V10, uses quad-bit 3 Tuned by AKG tuned by AKG as a bundled earphone, while the G5 uses the Cresin earphone as a bundled earphone, instead of the modular accessory Hi-Fi Plus with B & O PLAY and the matching earphone. H3 by B & O PLAY was released in collaboration with Bang & Olufsen. However, this time, instead of adopting a modular structure and focusing on strengthening the DAC, the bundled earphones also needed to use Bang & Olufsen's technology to fit the concept. However, there is a financial problem to use the Bang & Olufsen Beoplay H3, a low-end earphone with high-end sound equipment lineup, as a bundled earphone. It is said to have secured quality and reduced costs. Basically, Bang & Olufsen was responsible for the sound-tuning part of the earphone and Cresin provided technology to produce the earphone, which was produced by Bang & Olufsen's inspection. It is necessary to pass Bang & Olufsen's inspection, but only to be able to insert the logo of Bang & Olufsen.
The basic design is round oval and reinforced plastic is used as the base x-frame. The exterior uses machined aluminum with the logo of Bang & Olufsen, and the round tuck placement technology used by Bang & Olufson's Beoplay H3, which rounds the aluminum tube around the aluminum for sub-100 Hz bass. There are some opinions that the ear sleeves are small and medium and only two types are available, and there is no large ear sleeve.
The cable uses a woven cable up to the Y-branch, which improves durability but also has the problem that fluff can occur. And a microphone and a remote are placed on the left unit cable. In addition, the cable using the fabric material has the advantage that there is no twisting phenomenon. However, the cord touch noise is so severe that touch noise occurs at the part where the cable closes to the clothing even if the body moves. The driver unit is said to use polyurethane film, a highly elastic material developed by LG Electronics. However, the driver information was not disclosed for unknown reasons.
Although it is generally evaluated as having a level contributed by Bang & Olufsen, it is regarded as a quantum level because it uses Cresin-specific weaving cable, LG driver, and above all, has not assigned a model name in Bang & Olufsen. have. However, there is a view that this was caused by Bang & Olufsen's passive response in order to minimize the leakage of technology because it was produced by OEM method.
As a result of the performance measurements, the measurements were found to be quite compliant. Based on the DF-OliveWell target, it has more bandwidth and a relatively flat measurement than the Galaxy Note 7's bundled earphones and EarPods. The measurements are better than the original Bang & Olufsen H series earphones, which have a narrow band and a little bass relative to the DF target. However, considering the overall build-up with reviews by users who actually listened [19], it shows similar performance compared to the quad-bit 3 Tunes by AKG, the bundled earphone of the previous V10. Another measurement shows that the nonlinear distortion is slightly reduced, but it's almost the same as the V10's bundled earphone, Quadbit 3 Tunes by AKG. Therefore, even if you lose the bundled earphones, the performance is similar to Quadbit 3 Tuned by AKG, and as the original B & O bundle earphones are too expensive, they do not need to buy new B & O bundle earphones. Of course, given the uniqueness of smartphone bundled earphones, the majority admit that comparison is meaningless.
