September 13, 2012 at 11:48Reviews for the Nokia Lumia 920 and Nokia Lumia 820
Hello, Habr!
Many of you probably followed the presentation of Nokia and Microsoft in New York, where we presented a number of mobile accessories and, most importantly, the world's first working smartphones running the Windows Phone 8 operating system - these are the Nokia Lumia 820 and the flagship model Nokia Lumia 920 .
We are proud of the presented products, combining many advanced and innovative technologies together with an attractive design, and in this post we will tell you in detail why the new devices are so remarkable.
Nokia Lumia 920
Both devices are distinguished by Nokia’s bright corporate design, which first appeared in the Nokia N9 smartphone - similar cases were found in both Nokia Lumia 800 and Nokia Lumia 900. The
flagship Nokia Lumia 920 model is made of a single piece of polycarbonate, as was the case with the N9 and Lumia 800 / 900, due to which excellent impact resistance of the device is achieved. The device’s body also hides the copper induction coil for wireless charging according to the Qi standard, which provides only 10% less energy efficiency than conventional wired chargers, but greatly simplifies the charging process compared to them.
Nokia Lumia 820 is a smartphone with a removable housing. We are talking about the case, since in the process of replacing the only part that is left untouched is the front part with the screen - this will give a lot of space for accessories manufacturers to imagine. However, there will be plenty of branded cases: along with the start of sales of the device, both color and functional cases will appear with the possibility of the same wireless charging and increased dust and moisture protection characteristics.
Nokia Lumia 820
The physical buttons of both devices are made of zirconium ceramic. This material is not only extremely pleasant to the touch, but also incredibly durable. The Nokia Lumia 920 is also made of ceramic with a rear PureView camera - we will return to it. The composition of the physical buttons has remained unchanged since Windows Phone 7: it is a volume rocker, a screen lock button and a camera shutter button. The Windows function keys on the devices have not changed either, and, as before, they are three touch buttons “back”, “Windows” and “search” located under the screen.
Above the screen of new smartphones are a speaker, ambient light and proximity sensors, as well as a front camera. Nokia Lumia 920 uses a front-facing HD camera with a resolution of 1280x960 pixels for video calls, while the Lumia 820 uses a VGA camera with a resolution of 640x480 pixels.
On the top of the devices is a headphone output. The Nokia Lumia 920 also has a microSIM card tray (in Nokia Lumia 820, a micro-SIM is located under the rear panel). At the bottom of the smartphones are microUSB for charging and wired data transfer, as well as microphones for talking with the noise reduction function.
Nokia Lumia 920 uses the most advanced 4.5-inch display made on an IPS-matrix with a resolution of 1280x768 pixels - simple arithmetic shows that the pixel density per inch of this screen is record-breaking and is 332 ppi, which is more than that of the iPhone 5 and Samsung Galaxy S3. The display uses PureMotion HD + technology, which means that the pixel switching speed is more than 2 times faster than any other screen. As a result, the picture looks sharper and smoother when viewing dynamic content. This effect is enhanced by the use of a thinner but more durable second-generation Gorilla Glass, which, coupled with an absent air cushion, creates the feeling that the content is located directly on the screen, and not under a thick layer of glass.
The screen in the Nokia Lumia 820 is made using AMOLED technology. Its dimensions are 4.3 inches and a resolution of 800x480 pixels. In fact, this display completely repeats the screen characteristics of the Nokia Lumia 900, which was the flagship until recently. But unlike the Nokia Lumia 900, Nokia Lumia 820 now also uses the updated ClearBlack technology for comfortable reading in very sunny weather.
Moreover, the screens of the new Lumia devices recognize touch not only of fingers, but also of gloves, for example, which is especially important in countries with such a climate as in Russia.
This was made possible thanks to the use of the Synaptics ClearPad 3250 touch sensors located directly in the display cell: due to this arrangement, the recognition force is three times higher than that of other screens. The new Nokia Lumia can simultaneously recognize up to 10 taps on the screen, which usually equals the maximum number of fingers. Smartphones are able to recognize the area and nature of pressing, and are also guided by the proximity sensor, so that they will not call random contacts from the pocket of your pants on their own.
The flagship Nokia Lumia 920, as many expected, is indeed equipped with a PureView camera. However, if in Nokia 808 PureView our engineers took the path of using a large sensor with a size of 1 / 1.2 inches and a huge resolution of the matrix, this time it was decided to use a 1/3 inch sensor with a normal resolution of 8.7 megapixels and a pixel size of 1.4 microns.
The main feature of the PureView camera in the Nokia Lumia 920 is a sensor with a new generation of BSI (Backside illumination) technology. The difference between the BSI and the more familiar FSI (Frontside Illumination) front-illuminated sensors is that the BSI-sensor makes it easier to get light on the sensor’s photodiodes. In an FSI sensor, light is forced to pass through the metal wiring and circuit elements before it reaches the photosensitive elements at the base of the sensor. In the backlit sensor, the reverse structure is used, in which all the wiring is located at the base of the sensor, and the photosensitive surface is located immediately after the microlenses and light filters. As a result, a greater number of photons are incident on photosensitive diodes, even in low light conditions.
Pictures taken by Nokia Lumia 920
To improve the quality of photos and videos shot on the Nokia Lumia 920 in low light conditions, we used an incredibly large f / 2.0 aperture. To get this 16: 9 aspect ratio, we focused on creating an optical design different from other cameras. Therefore, we made our sensors at least 10% more than similar sensors with the same resolution. Using non-standard larger sensors instead of publicly available serial ones allowed us to get real 16: 9 and 4: 3 aspect ratios, remaining unique among all smartphones. Only a few digital cameras use such sensors.
However, the most significant improvement in the latest PureView camera is different - it is an optical image stabilizer OIS (Optical Image Stabilization). There are smartphones on the market that use digital stabilization algorithms, but they are all inferior to optical stabilization systems.
Optical stabilization systems use a gyroscope to determine the angle and direction of motion by moving the lens of the optical system in the opposite direction to compensate for unintentional movements. A similar principle is applied in active noise reduction technologies.
Adding optical stabilization to a smartphone is already a rather difficult task, but we managed not only to integrate it into the Nokia Lumia 920, but also bypassed the effectiveness of optical stabilization of many manufacturers of digital cameras by using lighter components that are easier (and faster) to move during stabilization. Instead of shifting one lens included in the optical system to compensate for camera shake, Nokia’s optical stabilization system moves the entire optical unit, which consists of five Carl Zeiss aspherical lenses, perfectly synchronized with the unintentional shake of the smartphone.
Many optical stabilization systems are able to cope with a certain frequency of movements. Our laboratory tests showed that the PureView optical stabilization system can handle approximately 500 movements per second, which is almost 50% more than conventional stabilization systems.
However, in addition to the fast movement speed of the optical unit, the system must also have an incredible response to all unintentional jitter. To achieve an instant reaction, we used a closed system that monitors the position of the optical unit in real time, even while this unit is moving to the calculated position. This process occurs five times faster than in existing optical stabilization systems, and is 300 times longer than the person’s reaction to the expected event.
The Nokia Lumia 920 also uses a new powerful LED flash, which provides a comparable level of backlighting with xenon, but it works continuously. Yes, you can use Nokia as a flashlight again.
Optics: Carl Zeiss Optics
Optical stabilizer: Barrel shift type Shutter
speed: up to 3EV (8 times slow shutter speeds)
Focal length: 3.73 mm
Focal length in 35 mm equivalent: 26 mm - 16: 9; 28 mm - 4: 3
Aperture: f / 2.0
Focusing range: 8 cm - ∞
Design: 5 elements, 1 group. All lenses are aspherical
Optical format: 1/3 ″
Sensor: BSI (Backside illuminated)
Pixels: 3553 x 2448 - 8.7 MP
Pixel size: 1.4 μm
Video recording: Full HD 1080p, 30 frames per second
The camera of the younger model Nokia Lumia 820 cannot boast of the presence of PureView technology, however, it still allows you to take good pictures. The device uses an 8-megapixel camera with Carl Zeiss optics. Such a camera allows you to take pictures with a resolution of 3264 × 2448 pixels and shoot video in FullHD, that is, in a resolution of 1920 × 1080 pixels, with a frequency of 30 frames per second. The flash in Nokia Lumia 820 consists of two LEDs.
Both devices also use Rich Recording technology, which allows you to capture very quiet and very loud sounds with virtually no distortion as the human ear can record video using special High Amplitude Audio Capture (HAAC) microphones. The Nokia Lumia 920 uses three HAAC microphones, whose recording quality does not suffer at a sound pressure level of 140 dB, and the Lumia 820 uses two such microphones. For comparison, conventional microphones already at a sound pressure level above 120 dB begin to create significant distortion.
In addition to the “iron” capabilities of PureView, it is worth noting that Nokia’s exclusive camera software capabilities in Windows Phone 8 are “lens” applications built into the camera that allow you to apply various filters to photos in real time. So, you can arrange yourself something like Instagram or take beautiful panoramic pictures using Microsoft Photosynth.
Just note that the communication capabilities of the Lumia 920 and Lumia 820 are the same, so all the information below applies to both devices.
This time, happiness is near: the devices support LTE in five bands, including those operated in Russia (the LTE Yota Networks network, which can be connected either through Yota or through MegaFon, works in a suitable range of 2.5-2, 7 GHz). LTE speed in new devices is limited to 50 Mbps, but it is still 2.5 times more than the speed at which Yota provides its services. For users who do not want to spend extra on 4G, there is support for the HSDPA category 24 protocol, with which you can achieve speeds of 42.2 Mbit / s.
The new devices are equipped with Wi-Fi modules (802.11a / b / g / n) with the ability to link Wi-Fi channels and Bluetooth 3.0 module.
To ensure navigation in the device, GPS and Glonass positioning systems are used. Thanks to the use of A-GPS technology, the cold start of the navigator is limited to a couple of seconds - in this case, the initial positioning is carried out by the identifiers of cells and Wi-Fi hotspots. But even without activating the cellular network and with Wi-Fi turned off, the smartphone finds satellites in a few seconds.
The NFC module, which is a necessity for smartphones on Windows Phone 8, can also be attributed to communications. But in our case, this is not a convention for the certification of devices by Microsoft, but an important element that simplifies the use of a number of accessories - docks, headphones, headsets, wireless speakers - created specifically for the new Nokia Lumia smartphones. However, we will talk about accessories in a separate post - there really is something to tell about. In addition, the NFC module is tightly integrated into Wallet, a special application in Windows Phone 8 that allows you to make purchases using your smartphone.
Both devices run on Qualcomm Snapdragon S4 dual-core processors with a clock frequency of 1500 MHz, Adreno 225 graphics and 1 GB of RAM. The current model of the processor MSM8960, made by 28-nanometer technology, is characterized by low power consumption and high performance.
The Nokia Lumia 920 uses a 2000-mAh BP-4GW battery. In theory, its capacity is enough for 17 hours of talk in 2G networks, 10 hours of talk in 3G networks, about 6 hours of watching videos and 67 hours of listening to music. The maximum standby time is 400 hours. The junior model Nokia Lumia 820 is equipped with a not so powerful BP-5T battery at 1650 mAh, so that the battery reserve can be written off by about 17%.
You can charge the devices using a proprietary wireless charging standard Qi. This standard was developed by the Wireless Power Consortium, a consortium of 126 companies, so that in the future this charging can be used to charge other devices.
With memory, everything is more interesting.
Despite the fact that Windows Phone 8 introduced full support for microSD memory cards, Nokia Lumia 920 had to abandon their support due to the monolithic case made of polycarbonate, whose characteristics could suffer with the advent of an additional slot. However, as practice shows, the average buyer should be enough for 32 GB of internal memory, especially since part of the information can be stored in the cloud. In Nokia Lumia 820, by contrast, you can use microSD up to 32 GB, but the internal memory is 8 GB.
In addition to a number of hardware innovations from Nokia, new smartphones, of course, carry a completely new feeling of use thanks to the Windows Phone 8 operating system: here it is worth remembering the native support for Skype already presented and, for example, the possibility of making contactless payments using the Wallet application . But while Microsoft does not allow us to talk about all the features of the new operating system, we will list our own exclusives available on this OS.
As we already said, in the interface of Nokia Lumia 920/820 cameras you can choose “lenses” - applications whose work is closely tied to photography. In addition to several “lenses” from Microsoft - the Blink application that allows you to take photos from a series of pictures without blinking people and the Photosynth application for creating full-fledged panoramas - the new Nokia Lumia will have exclusive Best Shoot lenses for removing objects and Cinemagraph from the frame, with with which you can make animated gifs with the ability to animate any area of the frame.
Offline support for Nokia Maps will appear in Windows Phone 8, and third-party application developers will be able to use the cards. This means that if you previously downloaded maps of the region you need and you suddenly did not have a connection to the Network, any application that uses maps in its work through the WP8 API will be able to display them. In addition, it will simply allow you to save Internet traffic once again.
Now voice turn-based navigation for Nokia motorists Navigator can be called directly from Nokia Maps. Moreover, voice step-by-step navigation for pedestrians will also appear. Moreover, in the pedestrian navigation for laying routes will use walking trails, underpasses, stairs, etc. - competitors still use only roads for laying routes for pedestrians, ignoring only the sides of traffic.
Augmented reality will also appear on Nokia Maps with facility maps - on the Nokia Lumia WP8 smartphones, indoor navigation will appear, so now you can easily find the place you need inside the shopping center, stadium, airport, and even more so you won’t get lost.
With the help of augmented reality, you can not only find out what is around you, but also look at the route laid through the smartphone’s camera, clearly realizing where to turn next.
On the new Nokia Lumia smartphones, the updated Nokia Transport app will also appear, laying the route using public land and underground transport. The application already familiar to the current owners of Nokia Lumia in Windows Phone 8 will support the search history and discreetly receive the latest updates “over the air”. And thanks to the close integration of maps with the system, this application will be used in Nokia Maps when laying a walking route.
Of course, do not neglect the huge number of third-party applications for Windows Phone. In a week, Microsoft will officially unveil the Windows Phone 8 SDK, and due to the support of native code and an expanded number of APIs, the number of these applications will grow significantly.
