Nokia Lumia 920 (codenamed Phi) is a smartphone developed by Nokia that runs the Windows Phone 8 operating system. It was announced on September 5, 2012, and was first released on November 2, 2012. It has a 1.5 GHz dual-core Qualcomm Krait CPU and a 4.5" IPS TFT LCD, as well as a high-sensitivity capacitive touchscreen that can be used with gloves and fingernails; the display is covered by curved Gorilla Glass and has a 9 ms response time. The phone features an 8.7-megapixel PureView camera with OIS; it was the first smartphone camera to implement that technology, as well as to support Qi inductive charging. The phone comes with 32 GB of internal storage, but has no expandable storage. The Lumia 920 was released to mixed to positive reception. Most critics noted the device as the first Windows Phone 8 device to truly match its Android and iOS competitors in hardware, with high-end specifications, a Nokia PureView camera and unique features such as wireless inductive charging. Following this, the Lumia 920 would frequently be listed among the "elite" group smartphone during its time, otherwise populated by heavyweights from Apple and Samsung. This represented the first time a Windows Phone device had been considered to have powerful and impressive enough hardware to qualify as a truly high-end flagship device. Many features such as the super-sensitive capacitive screen and wireless inductive charging were popularised by the device and were found in later high-end Android phones. The Lumia 920 went on to win 12 awards. Some reviewers criticised the thickness and weight of the Lumia 920, so Nokia released the Nokia Lumia 925, a lighter and thinner version of the Lumia 920 with an aluminium body and an improved camera. The Nokia Lumia 930, successor to the Lumia 92x series, was announced at Build 2014 on April 2, 2014.
Hardware
The Nokia Lumia 920 shares the "Fabula" design language of its predecessors, the Lumia 900 and 800, as well as the Nokia N9, with a unibody polycarbonate shell. Multiple colours with glossy and matte finishes were available.
Processors, memory and storage The Lumia 920 has a 1.5 GHz dual-core Qualcomm Krait CPU, a Qualcomm Adreno 225 GPU and 1 GB of system RAM. The Lumia 920T variant for the Chinese market comes with a 1.7 GHz dual-core Krait CPU and an Adreno 320 GPU. All variants of the Nokia Lumia 920 come with an internal storage capacity of 32 GB and do not support microSD expansion.
Screen The Lumia 920 has a 4.5-inch (114 mm) curved Gorilla Glass display with a resolution of 1280x768 (WXGA) and an aspect ratio of 15:9, using enhanced IPS screen technology which Nokia calls "PureMotion HD+". It has less than 9 ms average transition times, compared to an average of 23 ms for conventional IPS LCDs, which reduces motion blur. The screen has ClearBlack polarisation filters and an automatic adaptive system for adjusting brightness, colour and contrast details to compensate for lighting.
Camera The Lumia 920 has Nokia's PureView technology on the rear camera, featuring an optically stabilised 8.7-megapixel BSI image sensor (1/3.2" sized, much smaller than the previous Nokia 808 Pureview) with a f/2.0 Carl Zeiss Tessar lens, short-pulse high-power dual-LED flash and 1080p HD video capture. Pixel size is 1.4 μm. The front camera encloses a 1.3-megapixel sensor capable of capturing HD video at 720p. The stabilization was the first in a cellphone.
Controversy On September 6, 2012, Nokia apologised for an advertisement showing a video supposedly shot from somebody holding a Lumia 920 on a bike, but which was actually shot by somebody holding a camera in a van (as it can be seen in the reflections on a window). However, a later review indicated that the camera performance was comparable to that portrayed in the advertisement.
Connectivity The Nokia Lumia 920, like its predecessor, supports 4G LTE technology. Other connectivity features include Wi-Fi 802.11 a/b/g/n, dual-band, Wi-Fi hotspot, Bluetooth 4.0, NFC and microUSB 2.0.
Battery and charging The Lumia 920 has a 2000 mAh non-user-replaceable battery, providing a maximum standby time of up to 19 days and maximum talk time of up to 7.5 (2G) or 10 hours (3G). In addition to USB charging, the Lumia 920 can be recharged inductively using the Qi standard. Rather than requiring the use of a physical connection to the phone, this allows the phone to be charged when placed upon a charging pad (which requires a separate power supply).
Software The Nokia Lumia 920 runs the Windows Phone 8 operating system. As with other Lumia devices, the 920 includes Nokia-exclusive apps, such as Nokia City Lens, an augmented reality software that gives dynamic information about users' surroundings using the camera. It also includes Nokia's HERE suite of apps, which provide offline maps, worldwide turn-by-turn voice-guided navigation and public transit information. Other bundled apps include Nokia Music, which streams thousands of songs for free, and Nokia Smart Shoot, which lets users capture selected parts of a photo by using a lens for the camera app that takes a number of photos in quick succession.
Updates
On December 19, 2012, Nokia started rolling out the Portico update for the Lumia 920 and 820, which also included a firmware update for the 920 with camera fixes and battery improvements. Current Lumia 920 devices are already shipping with the Portico update. From August 16, 2013, Nokia rolled out the Amber update, which is pre-installed on the Nokia Lumia 925 and 1020 and includes several camera and performance improvements, to every Nokia device running Windows Phone 8. From approximately January 13, 2014, Nokia rolled out the Black update to Nokia Lumia devices running Windows Phone 8. Notable features include an enhanced glance screen and a new camera interface as well as a new Storyteller app. Lumia 920 is not officially eligible for upgrading to Windows 10 Mobile, but Windows 10 Mobile Beta is available for Lumia 920.
