Unveiled on 28 April 2015 and first released in South Korea on 29 April 2015 and widely released in June 2015, as the successor to 2014's G3. The G4 is primarily an evolution of the G3, with revisions to its overall design, display and camera. The G4 received mixed to positive reviews; while praising the G4's display quality, camera, and overall performance, critics characterized the G4 as being a robust device that did not contain enough substantial changes or innovation over its predecessor to make the device stand out against its major competitors, but could appeal to power users needing a smartphone with expandable storage and a removable battery.〔〔 ==Specifications== The design of the G4 is an evolution of the G3, maintaining elements such as its rear-located volume and camera buttons. Several back cover options are available, including plastic covers with a diamond pattern and plastic covers coated in leather, stitched down the middle. Six leather color options are available. The G4 features a , 1440p "Quantum IPS" display, which LG stated would provide better contrast, color accuracy and energy efficiency over another display that LG did not explicitly specify. The G4 utilizes a hexa-core Snapdragon 808 with 3 GB of RAM, consisting of four low-power Cortex-A53 cores and two Cortex-A57 cores.〔(【引用サイトリンク】url=http://www.theverge.com/2015/4/28/8505589/lg-g4-smartphone-specs-announcement-launch-leather-android )〕 The G4 includes a removable 3000 mAh battery and supports Qualcomm Quick Charge 2.0 technology with a compatible AC adapter, which is not included.〔(【引用サイトリンク】url=http://www.phonearena.com/news/LG-G4-does-have-Quick-Charge-2.0-capabilities_id69163 )〕 The G4 comes with 32GB of storage with the option to expand the amount of available storage with a microSD card up to 2 TB in size.〔(【引用サイトリンク】url=http://lg.com/us/mobile-phones/g4/tech_specs )〕 The rear-facing camera has a 16-megapixel sensor with a f/1.8 aperture lens, infrared active autofocus, three-axis optical image stabilization, and LED flash. A "RGB color spectrum sensor" is located below the flash, which analyzes ambient lighting to optimize the white balance and flash color to generate more natural-looking images.〔(【引用サイトリンク】url=http://www.phonearena.com/news/LG-G4-color-spectrum-sensor-explained-helps-you-nail-perfect-white-balance-for-photos_id68778 )〕 The front-facing camera is 8-megapixels with an aperture of f/2.0.〔 The G4 ships with Android 5.1 "Lollipop", although the overall user experience is relatively similar to that of the G3.〔 The camera software was upgraded with raw image support, along with a new manual mode offering the ability to adjust the focus, shutter speed, ISO and white balance. Optionally, a photo can be taken automatically by double-clicking the lower volume button when the screen is off.〔 On October 14, 2015, LG announced that the G4 would be upgraded to Android 6.0 "Marshmallow", with its release to begin in Poland the following week.〔(【引用サイトリンク】url=http://www.theverge.com/2015/10/14/9536257/lg-g4-marshmallow-update-rollout )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「LG G4」の詳細全文を読む スポンサード リンク
