점점 더 많은 스마트폰 제조사들이 플래그십 기기에 유리와 금속 합금을 적용하는 추세인 가운데, LG는 2015년에 플래그십 기기를 차별화하기 위해 다른 방식을 선택했습니다. 하지만 그 인식이 단순히 겉모습에만 국한된 걸까요? LG G4에 대한 전체 리뷰를 확인해 보세요.
지난 4월 28일에 발표된 LG G4는 정확히 한 달 뒤인 5월 28일에 필리핀에 출시되었습니다. LG는 G2 출시 이후 현지 출시를 매우 빠르게 진행해 왔으며, G4에서도 동일한 신속한 공급을 이어가고 있습니다.

작성자 주: 이번 리뷰를 위해 한국 버전을 미리 받아보았으며, 필리핀 버전과 몇 가지 차이가 있습니다. 가장 눈에 띄는 차이는 듀얼 SIM 기능입니다.
디자인 및 건설.
자세히 살펴보지 않아도 G4와 G3는 서로 큰 외관 차이가 없을 수 있습니다. LG는 이미 G 시리즈와 뚜렷하게 연관된 시그니처 디자인과 폼 팩터를 가지고 있습니다. G4는 동일한 5.5인치 폼 팩터를 유지하지만 모서리가 덜 둥글고 아치형 형태를 가지고 있습니다.

가볍게 곡선진 디자인은 둥근 뒷표지를 만들고, 평평한 전면 패널을 향해 깎인 가장자리를 형성함으로써 구현됩니다. 이는 전면 유리 패널도 안쪽으로 아치형을 이룬다는 인상을 줍니다.
G4의 레이아웃과 버튼 및 포트 배치는 G3와 정확히 동일합니다. 그리고 측면에 물리적 버튼이 없기 때문에 G4는 매우 통일감 있고 견고해 보입니다.

뒤쪽에 16메가픽셀 대형 카메라가 있으며, LED 플래시, 색상 스펙트럼 센서, 양쪽 레이저 자동 초점이 배치되어 있고, 그 바로 아래에 전원 및 볼륨 조절을 위한 리어 키가 있습니다.
크기 면에서 LG G4는 LG G3보다 약간 더 두껍고(9.8mm 대 8.9mm) 무게도 더 나갑니다(155g 대 149g). 하지만 그 이유와 추가 무게가 어떻게 발생했는지는 정확히 파악하지 못했습니다.
디스플레이 및 멀티미디어.
LG는 LG G3에서 QHD 패널을 사용한 최초 브랜드 중 하나였습니다. 고해상도 디스플레이(1440×2560 픽셀)는 더욱 개선된 퀀텀 디스플레이와 함께 LG G4의 주요 특징 중 하나로 계속 유지됩니다. G4는 G3에 비해 더 높은 명암비와 넓은 색 영역을 제공합니다. 또한 LG는 LCD에 N-Type 액정(N형 액정)을 적용하여 G4의 밝기를 최대 25%까지 높이는 데 성공했습니다.

LG는 동시대 제품들(Galaxy S6, Xperia Z4, iPhone 6) 중 가장 큰 5.5인치 디스플레이 크기를 유지했지만, 전체 기기 크기는 iPhone 6 Plus와 같은 파블릿으로 분류될 정도로 크지는 않습니다.
높은 픽셀 밀도가 화면의 선명함과 명료함을 더합니다. 웹 브라우징과 동영상 재생에 탁월합니다. 밝기와 명암비가 향상되어 야외 가시성도 뛰어납니다.

주장된 98% DCI 색 영역은 일반인에게는 낯설게 들릴 수 있지만, G4와 G3를 나란히 두고 밝기를 최대로 올리면 IPS 퀀텀 디스플레이의 대비, 색 채도 및 전체 밝기 차이를 확인할 수 있습니다.
전면에 물리적인 홈 버튼이 없으며 모든 네비게이션은 Lollipop이 제공하는 일반적인 화면 내 전도성 키로 이루어집니다. 화면 대비 본체 비율은 73.6%로, G3의 76.4% 화면 대비 본체 비율보다 약간 낮습니다.

전작과 마찬가지로 G4에도 적외선 레이저가 탑재되어 있어 여러 가전 제품을 원격으로 제어할 수 있습니다.
뒤쪽에 있는 스피커는 바닥 구석에 배치되어 있는데, 놀라울 정도로 꽤 크게 들리고 기분 좋습니다.
카메라.
새로운 16MP 카메라는 f1.8 조리개와 1/2.6? 센서 크기를 가지고 있습니다. 조리개는 f1.8로 고정되어 있지만 수동 모드에서는 ISO(50 – 2700), 셔터 속도(1/6000초부터 30초까지), 화이트 밸런스(2400K – 7400K) 및 물론 수동 초점을 수동으로 설정할 수 있습니다.

카메라 앱은 세 가지 모드 — Simple, Auto 및 Manual를 제공합니다.
대부분의 사람들은 사진을 찍을 때 자동 모드에 의존하지만, 수동 모드는 대부분의 스마트폰 카메라에서는 얻을 수 없는 다양한 가능성을 제공합니다. 그 중 하나는 장노출 촬영 기능으로, 사진작가들이 dSLR 카메라를 사용해 하던 기술입니다.

카메라의 일부 설정을 수동으로 제어할 수 있어 자동 모드에서는 거의 불가능한 독특한 사진을 촬영할 수 있습니다. 여기서 촬영한 사진에서는 ISO를 50으로, 셔터 속도를 0.5초로 설정할 수 있었습니다.

You will see a lot of noise as the camera tries to compensate for the low-light environment.
Light trails such as the one below are only possible when you have Manual Mode and control the shutter speed.

Here's some sample video clips:
We found the tri-axis optical image stabilization system to work very smoothly when we need it and there were many occasions where it made a lot of difference when we're shooting.
LG dropped the extra LED flash and replaced with a color spectrum sensor. The purpose of this sensor is to identify and measure ambient light which then allows it to automatically adjust the white balance to compensate.
LG explains it more accurately:
CSS improves color accuracy by precisely reading the RGB values of the ambient light in a scene, as well as the infrared light reflected from objects. CSS uses this information to adjust the camera’s white balance and flash color to create images that are as close to what one would see with the naked eye. With Color Spectrum Sensor, no longer will reds appear as bright orange or whites as dull yellow.
The G4 also has a double-click on the bottom volume keys to quickly launch the camera app but it’s limited to only when the phone is in sleep/idle.
OS, Apps and UI.
LG managed to get Android 5.1 Lollipop on the G4 right out of the box. The G4 is perhaps the one flagship which has the latest version available in the market, Android 5.1.

The UI is simple, uncluttered and not much bloatware. LG's customization on top of Lollipop was at a bare minimum.
A lot of the practical usability features that LG introduced since the G2 have been integrated and improved on the G4. There's the double tap feature that's been copied by many, the Knock Code, Dual Window, QSlide and the customizable homescreen buttons.

The G4's familiar interface is pretty simple and easy to use that it gets things done really quickly. The bright, pastel-like colors of UX 4.0 follows a similar design signature as Android's Material Design principle. The virtual keypad and keyboard are both comfortable and easy to use.
LG also threw in 100GB of Google Drive free for 2 years. The 32GB internal storage is good but you can always supplement that via a microSD card slot which supports capacities of up to 2TB (yes, that's 2,048GB).
Performance and Benchmarks.
This is the first time we encountered a Snapdragon 808 chip which is a hexa-core platform composed of four ARM Cortex A53 running at 1.44GHz and two ARM Cortex A57 running at 1.8GHz.

The Qualcomm reference design has 2 x 2.0GHz and 4 x 1.5GHz for the Snapdragon 808 but LG slightly lowered the clock speed to 2 x 1.8GHz + 4 x 1.44GHz in order to better manage heat issues originally discovered with Snapdragon 810 in the G Flex 2.
We're expecting to get better scores on the G4 compared to the G3 although it won't be a huge jump from the 801 to the 808. However, the Adreno 418 graphics should offer a huge performance boost over Adreno 330 and help with pixel-pushing that 1440×2560 resolution.
| Benchmark | LG G4 | LG G3 |
|---|---|---|
| Antutu | 48,903 | 29,118 |
| Quadrant | 24,925 | 23,476 |
| Vellamo | 2,222 (Metal) | 1,593 (Metal) |
| 2,227 (Multicore) | 1,559 (Multicore) | |
| 4,176 (Chrome) | 2,181 (Chrome) | |
| PCMark | 4,812 | 3,404 |
| 3D Mark | 18,594 | 14,730 |
Benchmark scores showed close to 70% better performance from the G3 to the G4 as seen in the Antutu benchmark. There's also a 25% increase in performance from the graphics side as shown by 3DMark.

We observed better over-all performance on the G4 with fluid graphics, more responsive UI and efficient multi-tasking.
Call Quality and Connectivity.
LG released the dual-sim variant of the LG G4 in the Philippines. Both micro-SIM card slots are accessible at the back when you remove the cover (Note: Our review unit is a Korean model and only has one microSIM card slot). It's interesting that LG also opted to introduce the dual-SIM model in the Philippines as it is becoming the trend lately.
Voice calls are clean and crisp while SMS are sent and received promptly.

The Philippine variant which has a dual-SIM functionality is also dual-LTE. There's a complete suite of connectivity options ranging from WiFi, Bluetooth, NFC, Miracast and GPS with GLONASS support.
The G4 has a built-in LG AirDrive that allows you to manage the content of your handset wirelessly over WiFi or 3G. The LG Health also has a built-in pedometer which gives the handset some level of activity tracking for the user.
One of the features we really liked about the G4 is the built-in IR blaster which they first introduced in the G2 a couple years back and continued to be one of the most useful features to date.
Battery Life.
Given that the LG G4 still had the same 3,000mAh battery rating as the G3, we did not expect much in terms of battery life. However, the G4 has a couple of new features that should help in battery performance.
One of the biggest factors would be the Snapdragon 808 chip. It is manufactured in the 20nm process which is more power efficient compared to the 28nm of the 801. It also has 64-bit support and uses the big.LITTLE architecture which handles power consumption better with the low-power Cortex-A53 processor.

LG also tweaked the clock speed a little bit and reduced the max speed of the Cortex-A53 to 1.44GHz and the Cortex-A57 to 1.8GHz. This is in contrast to the 2.5GHz max clock speed of the Cortex-A15 on the G3 which can be a battery hog.
In our standard battery benchmark using PCMark, we were able to get a rating of 6 hours 25 minutes which is about 24% better than the 5 hours 16 minutes that the G3 got from the same test. With the manual battery test, we managed to get up to 11 hours and 30 minutes of video playback using MX Player at 50% brightness and 50% volume with an earphone plugged to the phone. This is about 15% - 25% better compared to the performance of the G3 using the same test.

We did not notice any excess heating of the device despite continued heavy use although the area around the camera lens is where most of the heat dissipates. Maximum core temperature we recorded was about 41.3 Celsius.
The built-in Battery Saver limits background services once the battery life reaches a low 15% so the last remaining juice is stretched. There's no built-in wireless charging on the handset but there's an optional folio case (sold separately) which supports it.
Conclusion.
LG tries to put a different twist in creating their next flagship smartphone. The G4 traded a bit of raw power and cold industrial design in favor of organic yet practical execution. Then they peppered it with a few sprinkles of interesting features like laser auto focus, camera manual mode and support for camera RAW.

The LG G4 is a breath of fresh air. The leather treatment is a surprise introduction that changes the way we regard the handset. The form factor and material design is so natural you won't have that urge to wrap it in a protective case.
LG took a great phone, the G3, and made it even better with the G4 -- what you get is an unassuming but genuine flagship handset.

Where can I buy battery door covers for my G4? I love the leather battery door cover but sometimes I’m afraid that it will get scuffed so I want to change the battery cover to a plastic one at times and enclose it in a cellphone case.
