Nokia Lumia 920 is a smartphone developed by Nokia that runs the Windows Phone 8 operating system.[1] 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 display, as well as a high-sensitivity capacitive touchscreen that can be used with gloves and fingernails;[8][9] the display is covered by curved Gorilla Glass. It supports Qi inductive charging (can be charged by being placed directly onto a charging pad) and features an 8.7-megapixel PureView camera with optical image stabilization for still images and videos. It comes with 32 GB of internal storage, but has no expandable storage.

The phone 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 popularized by the device and were found in later high-end Android phones. As some reviewers criticized the thickness and weight of the phone, Nokia released the Nokia Lumia 925, a lighter and thinner version of the Lumia 920 with an aluminium body[10] and an improved camera.[11]

On April 2, 2014, the Nokia Lumia 930, the successor of the Nokia's flagship Lumia 92x series, was announced at Build 2014.

Hardware
Like its predecessors, the Lumia 900 and 800, and starting with the N9, the Nokia Lumia 920 has a colored unibody polycarbonate shell with glossy and matte finishes. Multiple colors in addition to standard black were available.[12]

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.[13][14]

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+".[15] It has less than 9 ms average transition times, compared to an average of 23 ms for conventional IPS LCDs, which reduces motion blur.[16] The screen has ClearBlack polarisation filters and an automatic adaptive system for adjusting brightness, color and contrast details to compensate for lighting.
Camera
The Lumia 920 has Nokia's PureView technology on the rear camera,[17] featuring an optically stabilized 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.

Controversystem
On September 6, 2012, Nokia apologized 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).[18] 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.[3][20] Other connectivity features include Wi-Fi 802.11 a/b/g/n,[3] dual-band, Wi-Fi hotspot, Bluetooth 4.0,[6] NFC[21] 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).

Operating system and 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.[23][24][25] 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.[26] Current Lumia 920 devices are already shipping with the Portico update.[27]

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.[28]

Technical issues
Some users have reported their phone reboots randomly.[29] The Portico update was intended to fix these random reboot issues, but the issues remained after the update.[30] Further hotfixes addressing the issue were released in June 2015.[31]
Some users have complained that the battery drains too fast and the phone overheats.[32] Aloysius Low from CNET Asia did not notice such a fast rate of battery drain on other smartphones even with the same usage pattern.[33] The issue was fixed in the Portico update.[34]
Videos larger than 4 GB get corrupted when transferred to a computer.[35]
The Portico update introduced a brightness bug, but there is a possible workaround.[36]
Dust settles under the front-facing camera and the proximity sensor, potentially leading to dropped calls and preventing users from accessing phone-related menus. Owners of affected phones can have their screen replaced and a protective sheath fitted for free.[37][38] Compressed air can also be used to remove the dust.

Reception[edit]
Reviews[edit]
The Nokia Lumia 920 has received mixed to positive reviews. Many critics noted the Lumia 920's hardware as the first time a Windows Phone device could truly compete with the hardware of high-end Android and iOS devices. Critics praised the screen, camera and unique features of the device, while also criticizing the phone's heft and thickness. CNET rated it 4 stars out of 5, praising the screen, attractive design, great Nokia-exclusive apps and an enjoyable OS, while the negatives were the unimpressive battery life and heavy weight.[44] The user rating is 4.5 out of 5. ExpertReviews gave the Lumia 920 a rating of 5 out of 5.[45] Mobiledia gave it 4 out of 5.[46] Laptop Mag rated it 4 stars out of 5, praising the colorful design, superb camera, HD screen and inductive charging, as well as the useful Nokia apps. The cons were that it is relatively heavy and that Windows Phone 8 does not have as many apps as Android and iOS.[47]

Dan Nosowitz from Popular Science wrote: "I spent a long time with the Lumia 920, longer than I usually spend with review units of phones. This is a phone I was really excited about! But I just can't recommend it. It's way too bulky, the battery life is lackluster, and Windows Phone 8 has some big problems on top of that. It's not a bad phone; when you're swiping away through a gorgeous weather or news app, you completely forget its shortcomings, and it's nicely priced. But there are better phones out there."[48]

Adam Z. Lein from Pocketnow wrote: "Our final rating is going to be a 8.3 out of 10. The hardware, the screen, the camera, the sound quality, the video stabilization, and Nokia's custom apps are all extremely impressive. The pricing is pretty great too. The only negatives for me are really the large size and lack of user-replaceable battery. Everything else on this phone is top notch."[49]

Sam Biddle from Gizmodo wrote: "It kills me to say this, because I wanted to own this instead of an iPhone 5, but no. No you shouldn't. It's too big and heavy. It's not fun to own. It's not enjoyable to use. If you want a Windows Phone, check out the very good HTC 8X. But this? No, not this."[50]

However, Luke Hopewell from Gizmodo Australia wrote in reply: "Yes it's heavy, but it's something you get used to. Sam said that the phone is too heavy to even contemplate living with, and that's almost true. If you can get past the weight of the device, you're in for a treat. The weight is almost beneficial when it comes to taking photos, to be honest. It makes it easier to stabilise."[51]

Dieter Bohn from The Verge wrote: "The software and hardware tradeoffs inherent in the Lumia 920 could be worth it if you've bought into the Microsoft ecosystem, but for most people I don't think it's a sure bet."[52]

Jessica Dolcourt of CNET in her camera review wrote: "Photo quality was strong and fairly consistent, though photos had a blue cast to them and the Lumia 920 had problems with contrast and absolute sharpness compared with the others.
