History [ edit ]

A trademark application for the name Nexus One was filed by Google, Inc. on December 10, 2009. The Nexus One trademark was filed in International Trademark Class 9 for Computer Software Products Electrical Scientific Products with description of Mobile phones. [ 17 ] On March 15, 2010 it was announced that the application had been declined due to the mark already being granted on December 30, 2008 to Integra Telecom. [ 18 ]

On December 12, 2009, Google confirmed in a blog post that they had begun internal testing of the device. [ 19 ] Google stated that a mobile lab device had been given to its employees, at that time Google had not yet confirmed that a device would be sold to consumers. Wireless phone and data services for the device were not activated nor billed to Google; it was up to the employees to activate and pay for wireless service on their own. [ 20 ]

As of April 2010, the Nexus One had shipped to the US, the UK, Hong Kong, Germany and Singapore, although the phone has not been fully localized for non-US markets – the lack of satnav outside the US, [ 21 ] UK [ 22 ] and Ireland, [ 23 ] and the US English voice keyboard [ 24 ] being the most obvious shortcomings. A June 2010 update saw Google Navigation being enabled for additional 11 countries. [ 25 ]

Litigation [ edit ]

Upon the announcement of the Nexus One, Google received a cease-and-desist complaint by the estate of sci-fi author Philip K. Dick implying that the Nexus One namesake capitalized on intellectual property from his 1968 novel Do Androids Dream of Electric Sheep? . Isa Dick Hackett, daughter of Philip K. Dick, and several bloggers believed that the choice of name Nexus One as Google’s first Android phone was a direct reference to the Nexus-6 model series of androids in Dick’s novel. [ 26 ] [ 27 ] [ 28 ]

Apple targeted the Nexus One in a patent lawsuit against HTC, which was settled in December 2012. [ 29 ] [ 30 ] [ 31 ] [ 32 ]

The Nexus One reportedly had problems with 3G connectivity and touchscreen at launch. [ 33 ] Updates have since been issued for the operating system, including the addition of multi-touch abilities in the Android web browser and Google Maps functions. While the updates have reportedly also somewhat improved 3G connectivity for the T-Mobile USA version of the device, similar issues with the ATT compatible version have not yet been addressed. A class action lawsuit is pending against Google on the matter, as the phone has problems connecting to 3G networks in areas with less than ideal coverage.

PenTile matrix pixel arrangement of the AMOLED screen

At time of launch, the Nexus One had a 3.7#160;inch AMOLED screen with PenTile matrix pixel arrangement. [ 34 ] [ 35 ] The raster resolution is 480×800 pixels, however each pixel in the PenTile RGBG display is represented by only two subpixels on average, using subpixel rendering rather than the three found in most displays, meeting the definition of WVGA according to the Video Electronics Standards Association specifications for measuring resolution. [ 36 ]

Citing supply shortages of AMOLED displays, HTC announced on July 26, 2010 that the Nexus One would begin using Super LCD display technology instead of AMOLED. The Super LCD display was described as having greater power efficiency and color accuracy than the AMOLED display, while sacrificing the lauded color saturation and deep blacks of the original display. As of January 15, 2011 or earlier, all Nexus Ones available via Brightstar, Google’s worldwide distribution partner for Android development phones, shipped with Super LCD instead of AMOLED. [ note1 1 ] [ 37 ]

The capacitive touchscreen which uses the Synaptics ClearPad 2000 sensor [ 38 ] supports multi-touch gestures limited to single finger input and 2×1D two finger gestures. [ 39 ] [ 40 ] [ 41 ] It has an illuminated trackball which can emit different colors of light based on the type of notification being received. A voice processor developed by Audience uses a second microphone (on the back) to suppress background noise during phone conversations. [ 42 ] A 4-conductor TRRS style 3.5mm stereo headset jack is also provided, adding microphone and pause/resume/next/previous functions to the stereo earphones. [ 2 ]

The phone features a 5.0-megapixel auto-focus camera with LED flash and digital zoom, GPS receiver, Bluetooth 2.0. and 802.11b/g Wi-Fi abilities. [ 43 ] [ 44 ] The Snapdragon processor allows for many advanced abilities including 720p video playback. [ 45 ] There is built in hardware decoding for H.263. H.264 and MPEG-4 video, and can play MP3, AAC+. Ogg Vorbis. WAV. and MIDI audio, and display JPEG.

GIF. PNG. and BMP image formats. It has a micro USB port which conforms to the GSMA Universal Charging Solution instead of the common mini-USB port, or HTC’s mini-USB compatible format (ExtUSB ). The microSD card slot allows expansion up to 32 [ 46 ] gigabytes of card storage.

Applications can be installed either to the 512 MB internal flash memory, of which 190 MB are available for that purpose, or to the microSD card. Many applications, however, are not optimized for installation on external memory, and high data I/O throughput to the microSD may cause applications running off of external memory to freeze.

Network frequencies [ edit ]

As of March 16, 2010, there are two versions of the Nexus One, which differ in the 3G frequencies they support. [ 47 ] The GSM frequencies supported by both models are 850#160;MHz, 900#160;MHz, 1800#160;MHz and 1900#160;MHz. Additionally, the original Nexus One (PB99100) also included UMTS frequency bands 1 (2100#160;MHz), 4 (1700#160;MHz), and 8 (900#160;MHz).
