The Motorola Atrix (also known as Motorola Atrix 4G and Motorola Atrix MB860 ) is an Android- based smartphone from the US manufacturer Motorola , which was first presented in January 2011 at CES 2011. Using the latest technology and several innovations , the smartphone received ten awards from specialist magazines during the fair, including CNET.com in the Best Smartphone category .
Background and development
The smartphone was presented to the public for the first time at the US trade fair CES in January 2011. The Motorola Atrix garnered attention in the trade press from the start. 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 the modern HSPA + cellular standard . Secondly, has Motorola Atrix with its docking station, a unique selling proposition ( Engl. USP unique selling proposition, USP ).
Launches and sales
According to Motorola , the smartphone will be available in the USA under the name Motorola Atrix 4G from the 1st quarter of 2011. Since AT&T recently lost the exclusive distribution rights for the Apple iPhone , the Atrix is to follow in its footsteps and be particularly strongly promoted. In Great Britain it was planned to introduce the Motorola Atrix (without the name suffix 4G ) via the mobile operator Orange in the 2nd quarter of 2011. The Motorola Atrix 4G was also released in Germany in the second quarter of 2011 under the name Motorola Atrix .
In October 2012, Motorola officially announced that it would phase out support for the Atrix. The smartphone no longer receives an update to Android 4.0 Ice Cream Sandwich .
technology
processor
The heart of the device is a Tegra 250 SoC ( system-on-a-chip ) manufactured by the US manufacturer Nvidia using the 40 nm process . The Motorola Atrix is after the LG P990 Optimus second smartphone with the second generation of Tegra . The primary computing tasks are performed by an ARM Cortex A9 CPU unit with two cores ( dual core ) clocked at 1 GHz. An eight-core ( Octacore ) ULP GeForce GPU, where the abbreviation ULP stands for ultra-low power , performs graphic calculations . Even when memory has Motorola opted for the energy-saving device and equipped the device with 1GB LP DDR2 -600 RAM .
The Tegra 2 has a high level of performance when it comes to encoding and decoding audio and video signals, which means that both playback and recording of high-resolution image material through to FullHD content would be possible. However, this is not supported by the official software.
Display
qHD resolution
Motorola is breaking new ground in several areas with the Motorola Atrix display . It is the first smartphone to be delivered with qHD resolution (Quarter HD - 960 × 540 px ). In this case, HD stands for the FullHD resolution 1920 × 1080 px , Quarter for a quarter . The resolution of the Atrix is a quarter of the FullHD image resolution known from modern flat screen televisions and computer monitors (FullHD = 2,073,600 pixels (1,920 × 1,080 px); qHD = 518,400 pixels (960 × 540 px)). With a screen diagonal of 4 inches , the device has a point density of 275 dpi .
PenTile matrix
Furthermore, it is the first LCD in the smartphone sector to use PenTile technology, which was previously mainly used in AMOLED displays . By Samsung purchased technology is essentially based on the so-called sub-pixel rendering , in which the RGB - subpixels are not only together, but also individually addressed. If a pixel is made up of three subpixels (red, green, blue) in normal LCDs , the PenTile technology only requires two subpixels.
Since the PenTile RGBW technology is used in the Motorola Atrix , the normal color space ( RGB , (R) ot (G) green (B) lukewarm) is supplemented by the achromatic color white .
Advantages of the PenTile-Matrix technology
Since the possible number of subpixels per area is physically and technically limited, the PenTile-Matrix technology can generate a higher nominal display resolution with an identical number of subpixels . By reducing two instead of three subpixels per pixel - compared to a display with the same nominal resolution and three subpixels per pixel - manufacturing costs can also be saved. The use of white subpixels can also reduce power consumption, since only the white subpixel has to be activated instead of the normally used red, green and blue subpixels ( additive color mixing ) to display the achromatic color white . Since the white subpixels already ensure a high level of basic brightness, the background lighting no longer has to be adjusted so high in order to obtain a sufficiently bright image. The other way around, the white sub-pixels can be used to generate a particularly high light intensity in conjunction with the background lighting.
Disadvantages of the PenTile-Matrix technology
Motorola certifies that the Atrix has a display resolution of 960 × 540 px; this results in a pixel total of 518,400 px. Since the Motorola Atrix display has a color space consisting of four basic colors ( RGBW , red, green, blue, white), but the pentile technology can only display two colors (subpixels) per pixel , this halves the nominal resolution. The first pixel contained the subpixels red and green, the second the subpixels blue and white. In a conventional LC display, a pixel is made up of all three sub-pixels (red, green, blue) required for display.
Example: The entire screen should display the color red . However, since only every second pixel can display this color, only every second pixel lights up red; the others remain switched off. With a conventional “RGB Stripe” display, a total of 518,400 pixels would now display the color red with the same nominal resolution, whereas the Motorola Atrix only has 259,200 pixels. Thus, the Atrix's display effectively shows a resolution of 960 × 540 px, but this was achieved with a reduction in display quality.
Practical test of the Atrix's PenTile display
The hardware magazine anandtech.com was able to subject the display to a detailed test.
While in theory there is a higher possible white value on the side of the advantages of PenTile displays, this could not be confirmed in practice with the Motorola Atrix . The Atrix achieved an average value of 364 cd / m² in the test .
For comparison (higher is better): Google Nexus One : 234 cd / m² ; LG Optimus Speed 2x : 399 cd / m² ; Apple iPhone 4 : 571 cd / m² .
The Motorola Atrix also only ended up with an average of 0.51 cd / m² in terms of black value .
For comparison (lower is better): Google Nexus One : 0.00 cd / m² (note: AMOLED display ); LG Optimus Speed 2x : 0.52 cd / m² ; Apple iPhone 4 : 0.6 cd / m² .
Accordingly, the contrast values are also average (higher is better): Motorola Atrix : 719; LG Optimus Speed 2x : 768; Apple iPhone 4 : 952; Motorola Milestone 2 : 1773.
The battery life of the device was also tested when surfing the Internet in a 3G network. The Atrix was compared with an LG Optimus Speed 2x , which has the same SoC ( Nvidia Tegra 2 ) as the Atrix and also has a 4-inch LC display. This makes it possible - at least roughly - to estimate whether the PenTile technology has advantages in terms of energy consumption in the specific case of the Motorola Atrix .
In the test, the Atrix achieved a battery life of 5.25 hours with a battery capacity of 1930 mAh. The LG Optimus Speed 2x had a battery capacity of 1500 mAh and a runtime of 4.07 hours. The battery life of the Atrix was therefore around 28% longer. However, since the battery capacity of the Atrix is also 28% higher, no indication could be found that would point to an advantage of the PenTile technology in terms of battery life in the case of the Motorola Atrix .
With regard to the image quality, the author refers to personal perception. While the disadvantages in terms of image quality compared to standard RGB stripe displays would effectively exist (especially with text), the author is less likely to be bothered by the higher resolution. The smartphone and GPU experts at anandtech.com , on the other hand, would get angry at the mere mention of PenTile displays.
Gorilla Glass
The display is protected from environmental influences by Gorilla Glass from Corning . This very popular protective glass is characterized by an improved break resistance and great hardness at the same time.
Storage
The device has an internal NAND flash memory with a capacity of 16 GB integrated ex works . The capacity can be expanded by up to 32 GB via a microSD HC memory card slot, which means that a maximum capacity of 48 GB can be achieved.
camera
The integrated camera can take photos with a resolution of up to 5 megapixels (2592 × 1936 pixels). An active pixel sensor (also known as a CMOS sensor ) is used to measure light . In poor lighting conditions, the camera is also supported by two switchable LED lights. In addition, the user has various recording programs available, including color effects , scenes and white balance . A 4-fold digital zoom is available for taking pictures of distant objects . Photos are saved in the popular JPEG format, and Exif 2.2 is also supported for storing metadata.
Movies can be recorded with a resolution of up to 720p (1280 × 720 pixels) at a frame rate of 30 FPS . The MPEG-4 and H.264 methods are supported for video and audio data compression of the recorded films .
In order to enable video telephony, a 0.3 megapixel ( VGA - 640 × 480 pixels) camera was installed on the front of the housing .
Radio links
No LTE support
Although the 4G suffix used on the US market suggests an implementation of the LTE cellular standard , the Motorola Atrix only masters the older and less powerful 3G standard . However, this is in the latest generation HSPA + , which enables a theoretical transmission speed of up to 14.4 Mbit / s. The reason for using the 4G suffix without actual LTE usage is probably due to the fact that in December 2010 the ITU ( International Telecommunication Union ) subsequently defined HSPA + as 4G technology. The resulting misinterpretation of the name abbreviation 4G is deliberately used by smartphone manufacturers and mobile phone providers as a marketing tool to promote sales .

Sensors
An acceleration sensor , a digital compass , a proximity sensor and an ambient light sensor serve as sensors . There is also a biometric fingerprint sensor with strip sensors on the back of the device , which can check the user's fingerprint to verify the user. This is also intended to be the on and off button and to wake up the smartphone from sleep.
measures and weight
The dimensions of the smartphone are 117.75 × 63.5 × 10.95 mm (H × W × D), with the device weighing 135 grams (with battery).
accumulator
Motorola installs an accumulator with a nominal charge of 1930 mAh, which is well above the standard in the industry.
According to Motorola, the battery in the 2G network lasts for around 530 minutes (8.8 hours) of talk or 264 hours (corresponds to 11 days) in standby . In the 3G network , the talk time according to official figures around 540 minutes (9 hours), standby time is reduced to 250 hours (equivalent to almost 10.5 days).
HDMI connection
On the left side - right next to the USB interface - there is a micro HDMI port according to the HDMI 1.3a standard . This allows audio and video signals to be sent to third-party devices such as televisions or AV receivers . Initially, only HD material in resolution 720p ( HD Ready ) can be played via the HDMI interface . Motorola has canceled a planned software update with which 1080p ( FullHD ) can be output. The hardware - Tegra SoC and HDMI connection - support playback up to 1080p.
equipment
Laptop dock
Optionally in connection with the Motorola Atrix , the manufacturer offers a notebook specially developed for the Atrix , the Motorola Lapdock. Contrary to the usual standard, this has neither a processor nor a mass storage device, as the entire computer infrastructure required by the smartphone is used. The micro-USB and micro-HDMI ports on the back of both devices act as interfaces for this . About 5 seconds after the smartphone has docked with the laptop, the operating system is available in webtop mode .
hardware
The notebook has an 11.6 inch display , a full keyboard in island style , a touchpad , stereo speakers and a 36 Wh battery . Furthermore, two USB 2.0 interfaces are available to the user , for example for using an external hard drive . Because many essential hardware components are omitted, space and weight could be saved in the construction compared to commercially available notebooks, whereby the device is only 13.9 mm thick and 1.09 kg.
The battery is sufficient, according to Motorola for an average useful life of over eight hours. When using the Internet via WLAN , the usage time is approximately 10 hours, when consuming video material approximately 6 hours. The Motorola Atrix will charge while it is connected to the laptop dock .
Webtop fashion
If the Motorola Atrix is connected to the laptop dock or the HD multimedia dock , it switches to webtop mode . This mode is based on an additional operating system - instead of Android, an unknown Linux distribution is loaded. The user interface corresponds to that of a desktop PC and offers a navigation bar known from Apple's Mac OS X at the bottom . This can be used, for example, to call up a full version of the popular Mozilla Firefox web browser version 3.6. This also has full support for Adobe Flash in the current version 10.1. Windows can be moved, minimized and changed in size as usual with standard desktop operating systems . The multitasking support also makes it possible to have several windows open at the same time.
Within the Webtop Mode , the Mobile View application provides full access to the functions of the smartphone . The user interface of the Atrix appears in a window that takes up about a quarter of the screen, with the option of maximizing it to full screen mode. The mobile phone can be conveniently navigated using the mouse pad and keyboard . Telephone calls or running Android applications are also possible in Webtop mode . If the Motorola Atrix is removed from the dock during a call , it is not interrupted due to the multitasking capability of Android . If the smartphone is inserted back into the docking station at a later point in time, the version last used appears - for example, the opened Firefox with the last active website. The noted status is not temporarily stored in the RAM , but is stored permanently on the internal 16 GB NAND flash memory . On the one hand, this does not put unnecessary stress on the RAM and, on the other hand, ensures that the smartphone does not lose this information when the battery is empty, but the access time increases.
Entertainment mode
The entertainment mode offers a range of functions similar to many modern televisions when external storage media are connected . A clearly arranged selection of the available media - music, pictures and videos - appears on the screen, through which you can navigate. This application is also comparable with the Microsoft Windows Media Center .
price
The new price of the Lapdock is now around € 90. Distributed by various internet providers. Updated September 18, 2013
HD multimedia dock
The HD Multimedia Dock uses a similar range of functions as the Laptop Dock , but uses already existing hardware . A requirement for use is an HDMI compatible HD computer monitor or HD television . With a total of three USB 2.0 ports , various peripherals can also be used, such as a mouse , keyboard or printer . A 3.5 mm jack plug is also available for outputting audio signals.
If the Motorola Atrix is docked to the HD Multimedia Dock , you can select on the screen whether you want to switch to Webtop Mode or Entertainment Mode . Both modes have already been discussed in more detail in the Laptop Dock section above . In contrast to the laptop dock , the screen of the Motorola Atrix does not switch itself off while using the webtop mode , but can continue to be used. For example, a virtual trackpad can be accessed if a mouse is not available. In entertainment mode , the Atrix has a special surface that is reminiscent of the Apple iPod and provides the basic multimedia navigation elements. Depending on the provider, the HD multimedia dock may also come with a remote control , which makes navigation easier, especially in entertainment mode .
Price
Definitive prices have not yet been given. The online retailer mobilecityonline.com has an official retail price of 60 US dollars. In a press release, the mobile operator AT&T contradicts this by naming a sales price without a subscription of around 190 US dollars. However, the sale price includes the AT & T remote control and a Bluetooth - keyboard and - mouse . Only the docking station is explicitly listed at the online retailer .
Standard dock
The standard dock is actually just a charging station for the smartphone . In addition to the battery charging function, relevant information such as the charging status, time and alarm time is displayed on the screen. There are also quick links to the most common applications (contacts, e-mail, music, pictures) and to set the backlight and the alarm clock. The angle at which the Motorola Atrix stands in the docking station was deliberately chosen to ensure optimal reading.
Price
According to online retailer mobilecityonline.com , the official retail price is around $ 50. The shop itself sells the item for around 40 US dollars. Motorola has not yet given any official prices .
Vehicle Dock
Another option that Motorola is offering for the Atrix is the Vehicle Dock ( eng. Vehicle = vehicle; Dock = eng. To dock ).
Vehicle Mode
If the smartphone is connected to the vehicle dock , it automatically switches to a special user interface with particularly large and easily accessible buttons . These can be defined by yourself and offer quick access to the most frequently used functions while driving. By default, this includes Google Maps for Mobile for navigation, phone, music and local information. A hands-free function is also integrated. Via voice input, destinations can be searched for or conversation partners selected.
Price
According to online retailer mobilecityonline.com , the official retail price is around $ 60. The shop itself sells the item for around 40 US dollars. Motorola has not yet given any official prices .
Wireless keyboard
Motorola by offering wireless keyboard specially on the Atrix oriented Bluetooth - keyboard on. There are special quick start buttons to start frequently used Android applications. When designing the keyboard, Motorola concentrated on making it as flat as possible. The keyboard connects to the smartphone using the Bluetooth profile HID ( Human Interface Device ). The keyboard can also be used with other devices, provided that it supports the corresponding Bluetooth profile.
successor
In July 2012, Motorola presented the successor to the smartphone , which is offered under the name Motorola Atrix HD . Compared to its predecessor, it offers a much more stable housing and a larger display that also supports a higher resolution. The Atrix HD is not a further development of the existing products, but a completely redesigned model. Motorola wants to use this to merge the Atrix and Razr series in the medium term.
