Background and Development
Smartphone to the U.S. trade fair CES was first introduced to the public in January 2011. In the trade press, the Motorola Atrix garnered attention from the beginning. On the one hand this was due to the advanced technology, such as the Nvidia Tegra 2 system -on-a - chip with two processor cores and 1 GHz clock frequency and the support of modern mobile HSPA . On the other hand, the Motorola Atrix with its docking station a unique selling proposition (English USP unique selling proposition, USP ).
Launches and sales
The smartphone is offered, according to Motorola in the U.S. under the name Motorola Atrix 4G from the first quarter of 2011. Since AT & T has lost market exclusivity for the Apple iPhone recently, to the Atrix follow in the footsteps and be particularly strongly encouraged. In the UK, the Motorola Atrix will be available (without the suffix 4G ) via the mobile operator Orange from the 2nd quarter of 2011. The Motorola Atrix 4G has been released in the 2nd quarter of 2011 in Germany under the name of Motorola Atrix.
In October 2012, Motorola announced officially, to phase out support for the Atrix. The smartphone receives an update more on Android 4.0 Ice Cream Sandwich.
Technology
Processor
The heart of the device is a product manufactured in a 40 nm process SoC ( system-on -a-chip ) of the type Tegra 250 of the U.S. manufacturer Nvidia. The Motorola Atrix is LG P990 Optimus after the second smartphone with the second generation of Tegra. The primary computational tasks takes an ARM Cortex A9 CPU unit with two cores ( dual core) clocked at 1 GHz. Graphical calculation assumes a octanuclear ( Octacore ) ULP GeForce GPU, the symbol ULP stands for Ultra -low power. Even when memory Motorola has opted for the energy-saving device and equips the device with 1GB LP DDR2 -600 RAM. The Tegra 2 has a high performance for encoding and decoding audio and video signals, whereby both the playback and recording of high-resolution images up to FullHD content would be possible. However, this is not supported by the official software.
Display
QHD resolution
Motorola treading with the display of the Motorola Atrix in several areas of new ways. So it is the first smartphone that the qHD resolution ( HD Quarter - 540 px × 960 ) is delivered. HD stands in this case for the full-HD resolution 1920 × 1080 px, quarterback for a quarter. The resolution of the Atrix is therefore a quarter of the known modern flat screen televisions and computer monitors, FullHD resolution (FullHD = 2,073,600 pixels ( 1,920 × 1,080 px); qHD = 518,400 pixels ( 960 × 540 px) ). With a screen size of 4 inches, the device has a pixel density of 275 dpi.
PenTile matrix
In addition, it is the first LCD in the smartphone market, which uses the PenTile technology, which has been built mainly on AMOLED displays. The selling of Samsung technology is mainly based on the so-called subpixel rendering, in which the RGB sub-pixels can be not only together, but also individually addressed. If during normal LCDs one pixel from each of three sub-pixels composed ( Red Green Blue ), the PenTile technology requires only two subpixels. Since the Motorola Atrix, the PenTile RGBW technology is used, the normal color space ( RGB, (R ) ot (G ) reen (B ) lue) is supplemented by the achromatic color white.
Advantages of the PenTile matrix technology Since the possible number of sub-pixels per area is limited physically and technically a higher nominal display resolution can be generated by the PenTile matrix technology at an identical number of subpixels. Through a reduction of two rather than three subpixels per pixel can - compared to a display with the same nominal resolution and three sub-pixels per pixel - also costs in production can be saved. The use of white subpixels can reduce power consumption in addition, as for the display of the achromatic color white only the white subpixels must be activated instead of the sub-pixels of red, green and blue usually used (additive color mixing). Since the white subpixel already provide a high background brightness, the backlight does not have to be so highly regulated in order to obtain a sufficiently bright image. The other way round the white sub-pixels can be used to produce in conjunction with the backlight a very high light intensity.
Disadvantages of PenTile Matrix Technology Motorola confirms that the Atrix a display resolution of 960 × 540 px; this gives a total of 518,400 pixels - px. Since the Motorola Atrix display a color space consisting of four basic colors has (RGBW, Red, Green, Blue, White ), but the Pentile technology can display only two colors ( subpixel ) per pixel, this halves the nominal resolution. The first pixel included the sub-pixels of red and green, the second the sub-pixel blue and white. In a conventional LCD display, a pixel from all three sets for the representation required three subpixels ( red, green, blue). Example: The whole screen should display the color red. However, since only every second consecutive pixels capable of displaying this color, only every second pixel lights up red; the others remain off. In a conventional " RGB Stripe " display 518,400 pixels total now would see the color red at the same nominal resolution, the Motorola Atrix is only 259,200 pixels. Thus, the display of the Atrix is indeed effective resolution of 960 × 540 px at, but this was obtained with a reduction in display quality.
Practice test PenTile display on the Atrix Could anandtech.com The hardware magazine undergo a detailed test the display. While in theory on the part of the benefits of PenTile displays a high potential value is white, this could not be confirmed in practice the Motorola Atrix. The Atrix reached an average value of 364 cd / m² in the test. For comparison ( higher is better): Google Nexus One: 234 cd / m²; LG Optimus 2x Speed : 399 cd / m²; Apple iPhone 4: 571 cd / m².
Also the black level of the Motorola Atrix closed at 0.51 cd / m² from just average. For comparison ( lower is better): Google Nexus One: 0.00 cd / m² (Note: AMOLED display ); LG Optimus 2x Speed : 0.52 cd / m²; Apple iPhone 4: 0.6 cd / m².
Correspondingly, also the contrast values on average ( higher is better): Motorola Atrix: 719; LG Optimus Speed 2x: 768; Apple iPhone 4: 952; Motorola Milestone 2: in 1773.
Also tested was the battery life of the device for surfing the internet in a 3G network. The Atrix has been compared to a LG Optimus Speed 2x, which has the same SoC (Nvidia Tegra 2) as the Atrix and also a 4 -inch LCD display. This allows - to assess whether the PenTile technology brings advantages in energy consumption with in the concrete case of the Motorola Atrix - at least approximately. When testing the Atrix reached with a battery capacity of 1930 mAh for a period of 5.25 hours. The LG Optimus Speed 2x came with a battery capacity of 1500 mAh to a runtime of 4.07 hours. The battery life of the Atrix was therefore higher by about 28%. Since the battery capacity of the Atrix but is also higher by 28%, thus no evidence could be found that points to an advantage of PenTile technology in terms of battery life in the case of the Motorola Atrix.
In terms of image quality, the author refers to the personal perception. While the disadvantages in image quality compared to standard RGB stripe displays effectively stocks (especially with text ), it bothers the author rather less, instead he enjoys the higher resolution. The Smartphone and GPU expert from anandtech.com, however, would be furious at the mere mention of PenTile displays.
Gorilla Glass
Protected against environmental influences, the display is Gorilla Glass Corning. This very popular protective glass is characterized by an improved fracture resistance along with high hardness.
Memory
The device has an integrated internal NAND flash memory with a capacity of 16 GB from the factory. About a microSDHC memory card slot can expand the capacity by up to 32 GB to expand, which enables a maximum capacity of 48 GB can be achieved.
Camera
The built-in camera can shoot photos at resolutions up to 5 megapixels ( 2592 × 1936 pixels). For light measurement is an active pixel sensor (also known as a CMOS sensor) to wake. In low light, the camera also receives support through two switchable LED lights. In addition, the user different shooting modes are available, including color effects, Scenes and White balance. To take pictures of distant objects, there is a 4x digital zoom. Photos are stored in the common JPEG format, Exif 2.2 is also supported for the storage of metadata.
Movies can be recorded with a resolution up to 720p (1280 × 720 pixels) at a frame rate of 30 FPS. For video and audio data compression of the recorded movies using MPEG -4 and H.264 are supported. ( - 480 × 640 VGA) camera installed in order to enable video calling, was on the front of the chassis, a 0.3 megapixels.
Radio links
No LTE support
Although the suffix used on the U.S. market 4G suggests an implementation of the LTE cellular standards, the Motorola Atrix dominated only the older and less powerful 3G standard. This, however, in the latest generation HSPA , which / makes a theoretical transfer speed of up to 14.4 Mbit s. The reason for using the name without addition of 4G LTE actual usage is likely to be due to the fact that in December 2010 by the ITU (International Telecommunication Union) HSPA was subsequently defined as 4G technology. The resulting occurring Falschinterpretierung the name abbreviation 4G is used by smartphone manufacturers and wireless service providers aware of as a marketing tool to promote sales.
Supported wireless connections
Supported Bluetooth profiles
Sensors
Serve as sensors, an acceleration sensor, a digital compass, a proximity sensor and an ambient light sensor. In addition, located on the back of the device, a biometric fingerprint sensor with strip sensors, which can verify its fingerprint for verification of the user. This is also the on-off switch as well as for waking the smartphones from hibernation thought.
Dimensions and weight
The dimensions of the smartphone be 117.75 × 63.5 × 10.95 mm ( H × W × D ), the device comes to a weight of 135 grams (with battery).
Accumulator
Motorola installed a battery with a nominal charge of 1930 mAh, which is well above the usual standard in the industry.
According to information on the part of Motorola, the accumulator in the 2G network is sufficient for about 530 minutes ( 8.8 hours ) Talk or 264 hours (which equals 11 days ) in standby mode. In the 3G network, the talk time is according to official figures around 540 minutes ( 9 hours ), the standby time is reduced to 250 hours (equivalent to nearly 10.5 days ).
HDMI port
On the left side is located - right next to the USB interface - a Micro HDMI port according to the standard HDMI 1.3a. This allows you to send audio and video signals to third-party devices such as TV or AV receiver. First, can be played in 720p (HD Ready) via the HDMI interface only HD material. Motorola has discontinued a planned software update that can be output with the 1080p ( FullHD). The hardware - Tegra SoC and HDMI port - support playback of up to 1080p.
Accessories
Laptop Dock
Optional in conjunction with the Motorola Atrix, the manufacturer offers a specially developed for the Atrix laptop, the Motorola Lapdock. This has, contrary to the usual standard, neither a processor nor a mass storage device, since the total required computer -Intra structure of the smart phone is being used. Micro USB and Micro HDMI port works located on the rear of both units as the interface. About 5 seconds after the smartphone has docked to the laptop, the operating system is in Webtop mode available.
Hardware
The notebook has a 11.6 -inch display, a full keyboard in Iceland -Style, a touchpad, stereo speakers and a 36 Wh battery. In addition, the user has two USB 2.0 ports are available, for example for use of an external hard drive. The fact that many essential hardware components are required, could be saved in the design compared to standard notebook space and weight, allowing the device is only 13.9 mm thick and 1.09 kg.
The accumulator is sufficient, according to Motorola for an average useful life of over eight hours. In the Internet via Wi-Fi, the useful life is approximately 10 hours, the consumption of video material about 6 hours. The Motorola Atrix is during the period, while it is connected to the laptop dock, loaded.
Webtop mode
Will the Motorola Atrix connected to the Laptop Dock or HD Multimedia Dock to the, it goes into Webtop mode. This mode is based on an additional operating system - Android instead of an unknown distribution of Linux is loaded. The user interface is similar to that of a desktop PC and offers at the bottom of a well-known from Apple's Mac OS X navigation bar. About this example, a full-fledged version of the popular web browser Mozilla Firefox in version 3.6 can be invoked. This also has full support for Adobe Flash in the current version 10.1. Window can be moved as usual commercially available desktop operating systems, minimized and resized. By multitasking support, it is also possible to have several windows open simultaneously. Within the Webtop mode can be accessed by the application Mobile View entirely on the features of your smartphone. The user interface of the Atrix appears here in one window, which roughly a quarter of the screen takes up where the possibility of this to maximize to full- screen mode. Can be easily navigated by the mobile phone via mouse pad and keyboard. Even phone calls or running of Android applications are possible in Webtop mode. Is removed during a call, the Motorola Atrix from the dock, this will not be interrupted due to the multitasking ability of Android. If the smartphone inserted at a later time in the docking station, the last used state appears - for example, the open Firefox with the last active website. The held status is in this case not cached in RAM but permanently stored on the internal 16GB of NAND flash memory. This is weighing on the one hand the RAM unnecessarily and ensures on the other that the smartphone with empty battery, this information does not lose, but it increases the access time.
Entertainment Fashion
The Entertainment Mode provides features similar to many modern television when connecting external storage media. Music, Pictures and Videos - - a clear choice of media available appears on the screen can be navigated through which. Compares this application is also using the Microsoft Windows Media Center.
Price
Meanwhile, the new price of the Lapdock is around 90 €. Sold by various Internet service providers. Updated 18.September.2013
HD Multimedia Dock
The HD Multimedia Dock uses a similar feature set as the Laptop Dock, but draws on existing hardware. A prerequisite for using a HDMI compatible HD computer monitor or HD TV. With a total of three USB 2.0 ports also can be used various peripheral, such as a mouse, a keyboard or a printer. In the other is a 3.5mm jack to output audio signals.
Will the Motorola Atrix docked on HD Multimedia Dock can be selected on the screen, whether to use the Webtop mode or in the Entertainment Mode. In both modes have already been addressed in the upper portion Laptop Dock accurate. In contrast to the Laptop Dock turns the Motorola Atrix screen while using the Webtop mode does not switch itself off, but can be used. For example, to access a virtual trackpad, if no mouse is available. In Entertainment mode, the Atrix is a special surface that is reminiscent of the Apple iPod and the basic multimedia navigation elements provides. Depending on the provider is the HD Multimedia Dock partially also a remote control in which facilitates the navigation, in particular in the entertainment mode.
Price Definitive prices were not mentioned above. The online retailer mobilecityonline.com called an official selling prices in the amount of 60 U.S. dollars. In a press release of the mobile operator AT & T contradicts with the entry of a sale price without subscription in the amount of approximately $ 190. However, the sale price at AT & T remote control and a Bluetooth keyboard and mouse. When online retailers only the docking station is explicitly referenced.
Standard Dock
The Standard Dock is in the strict sense only a charging station for your smartphone. In addition to the function of the battery - charging -related information are displayed on the screen like charging status, time and alarm. There are also quick links to the most common applications (contacts, email, music, pictures ) and to adjust the backlight and the alarm clock. The angle at which the Motorola Atrix is in the docking station, was deliberately chosen to ensure an optimal reading.
Price According to the online retailer mobilecityonline.com the official retail price is around 50 U.S. dollars. The shop itself sells the products already for around 40 U.S. dollars. Official prices were part of Motorola has not called.
Vehicle Dock
Another option, which is offered by Motorola for the Atrix, is the Vehicle Dock (English Vehicle = Vehicle; . = Eng Dock to dock - dock ).
Vehicle Mode When the smartphone is connected to the Vehicle Dock, it automatically changes to a special user interface with extra large and easily accessible buttons. These can even be defined and provide a quick access to while driving the most frequently used functions. These include default Google Maps for Mobile for navigation, telephone, music and local information. In addition, a hands-free function is integrated. By voice can be searched in the other goals or chosen interlocutor.

Wireless Keyboard
Motorola offers a wireless keyboard to be specifically geared to the Atrix Bluetooth keyboard. There are special quick- launch buttons available to start frequently used Android applications. In the design of the keyboard, Motorola has particularly focused its flat construction. Connection to the smartphone takes over the keyboard using the Bluetooth HID profile to (Human Interface Device). The keyboard can also be used with other devices, a prerequisite is a support of the corresponding Bluetooth profile.
Successor
In July 2012, Motorola introduced the successor to the smart phones, which is sold under the name Motorola Atrix HD. Compared to its predecessor, it provides a much more stable housing and a larger screen, which also supports a higher resolution. It is the Atrix HD not an evolution of existing products, but a completely redesigned model. Motorola wants to merge with this medium the Atrix and Razr series.
