The Nexus One (codenamed HTC Passion) is Google's original flagship smartphone manufactured by Taiwan's HTC Corporation. It became available on January 5, 2010 and uses the Android open source mobile operating system. Features of the phone include the ability to transcribe voice to text, an additional microphone for dynamic noise suppression, and voice guided turn-by-turn navigation to drivers.
The device is sold SIM unlocked (not restricted to use on a single network provider). Google offered T-Mobile USA and AT&T versions of the phone online in the United States before closing the online store in July 2010. A version for use on Vodafone (European) networks was announced on April 26, 2010, available in the UK on April 30, 2010. On March 16, 2010, the Nexus One device became available on the Google web store for sale in Canada for use with most Canadian carriers. In May 2010 Google announced the closing of the web store, with the intention to distribute the phone through partners around the world.
The bootloader of the phone is unlockable, see below.
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". 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.
On December 12, 2009, Google confirmed in a blog post that they had begun internal testing of the device. 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.
Isa Dick Hackett, daughter of Philip K. Dick, and several bloggers believe the name Nexus One is a reference to the novel Do Androids Dream of Electric Sheep? by Philip K. Dick, in which there are androids with a model designation of "Nexus-6".
At time of launch, the Nexus One had a 3.7 inch AMOLED screen with PenTile matrix pixel arrangement. 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.
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. To determine whether a phone has the AMOLED or SLCD display, power on while holding the volume down key or pressing the trackball and examine the MICROP line; 0b15 indicates AMOLED while 0c15 indicates SLCD. The internal sticker on the back side of the screen assembly can also be examined; part number 60H00443-03P indicates SLCD and part number 60H00287-00P indicates AMOLED. Finally, USB debugging or a terminal emulator app can also be used to examine the kernel log to determine which display the phone has.
The capacitive touchscreen which uses the Synaptics ClearPad 2000 sensor supports multi-touch gestures limited to single finger input and 2×1D two finger gestures. 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. 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.
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. The Snapdragon processor allows for many advanced abilities including 720p video playback. 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 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.
As of March 16, 2010, there are two versions of the Nexus One. Both versions of the Nexus One cover most major GSM and 3G providers in the US, Europe and Asia. On both phones, the GSM radio frequencies covered are 850 MHz, 900 MHz, 1800 MHz, and 1900 MHz. The original Nexus One (PB99100) also came along with UMTS frequency bands 1 (2100 MHz), 4 (1700 MHz), and 8 (900 MHz), allowing it to access 3G throughout Europe, as well as on T-Mobile USA and WIND Mobile and Mobilicity and Videotron in Canada. The second version of the Nexus One (PB99110) supports UMTS frequency bands 1 (2100 MHz), 2 (1900 MHz), and 5 (850 MHz), allowing it to access 3G in most of Europe, as well as on AT&T Mobility in the USA and Rogers Wireless, Fido Solutions, Bell Mobility, and Telus Mobility in Canada. The second version of the Nexus One also works on Telecom New Zealand's XT Mobile Network, Telcel's 3G Network and Telstra's Next-G network.
For more information on how to identify each model of the Nexus One and the differences between the two, please see this discussion on the official Android forum.
To determine what version of the Nexus One you have, take the battery out and look for the FCC ID number:
- FCC ID NM899100 is T-Mobile 3G
- FCC ID NM899110 is AT&T 3G
The Nexus One was released with Android 2.1 Eclair. Later, an OTA update of Android 2.2 Froyo was released, which introduced a number of highlights: a new Home screen, support for Adobe Flash 10.1, better Microsoft Exchange support, Wi-Fi tethering, SD-card installable applications, cloud to device messaging for two-way push sync functionality and an overall 2-5x performance improvement.
The integrated Media Gallery, developed by Cooliris, provides several new features allowing the user to browse, edit, and share photos and videos on the phone.
The Nexus One ships with non-removable third-party apps, including "Amazon MP3" and "Facebook".
The Nexus One OTA update to Gingerbread (2.3.3) started on February 23, 2011.
Platform development, hacking, and modification
The Nexus One ships with an unlockable bootloader allowing developers to participate in the Android Open Source Project in addition to developing applications. The Nexus One operating system can be unlocked and flashed with the fastboot utility which is part of the Android Open Source Project. Fastboot runs on Linux, Mac OS, or Windows and accesses the Nexus One through the USB port.
Users are able to gain root privileges on the device by unlocking its bootloader using the fastboot command "fastboot oem unlock." or by uploading specially crafted data packages via the Android debug bridge without the need to unlock the bootloader. Unlocking the bootloader or rooting the device allows the user to install non-official firmware images. Additionally, obtaining root privileges enables a user to override protected operating system features, and install arbitrary software. If using the fastboot command to unlock the bootloader to gain root through use of a custom firmware image, the user is presented with a Google-created screen stating that unlocking the bootloader will void the warranty as well as void any insurance plan. The popular CyanogenMod build of Android has already been released for the device.
Hidden menus can be accessed by dialling the following numbers:
|*#*#info#*#* or *#*#4636#*#*||"Testing" menu on the Nexus One and most other Android devices. It will bring up 4 categories: Phone Information, Battery Information, Battery History, and Usage Statistics. Also allows for disabling of the phone's cellular radio.|
|*#*#checkin#*#* or *#*#2432546#*#*||Force an immediate search for patches and updates.|
|*#*#talk#*#* or *#*#8255#*#*||GTalkService info|
|245#||Load Contacts from SIM card|
Comparison with other phones
Though the multi-touch experience of the Nexus One is generally similar to that of other multi-touch enabled smartphones (e.g., iPhone, Palm Pre, etc), the Nexus One hardware uses software to "enable" multi-touch ability, resulting in x/y axis confusion and preventing some multi-touch applications (e.g., games) from working as they should, compared to other phones. As of an update released February 2, 2010 it has pinch-to-zoom functionality in the phone's Browser, Gallery and Maps applications. In addition to these official applications, 3rd party apps that support multi-touch gestures are available.
HTC later released the HTC Desire, which has very similar specifications to the Nexus One. The Desire features an optical trackpad rather than a trackball, physical buttons rather than the touch sensitive buttons and an FM radio but lacks the noise cancelling dual microphones present in the Nexus One. The Desire is solely branded as HTC and runs HTC Sense rather than the stock version of Android. Sense can be switched off to get the stock Android experience however this was disabled on the retail HTC Desire.
- The Android 2.2 update caused the Nexus One to develop a serious Wi-Fi connectivity issue which causes the Wi-Fi to continually lose its connection and fail to reconnect. There are reports that Android 2.2.1 has fixed this issue, although there has been no official word from Google.
- The Nexus One reportedly had problems with 3G connectivity and touchscreen at launch. 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 AT&T 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.
- Initially, Google did not provide telephone support and consumers were forced to use its online Android forum. At this time, Google has stopped all support for the phone and customers are directed to contact HTC.
- The Nexus One is currently 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, UK and Ireland, and the US English "voice keyboard" being the most obvious shortcomings. Recent update saw Google Navigation being enabled for additional 11 countries.
- Goldman Sachs slashed their estimates for sales of the phone in 2010 by 70% due to the half-hearted marketing efforts by carriers.
On July 16, 2010, Google announced that the next shipment of Nexus One smartphones would be the last to be sold on their web store, stating "While the global adoption of the Android platform has exceeded our expectations, the web store has not. It’s remained a niche channel for early adopters, but it’s clear that many customers like a hands-on experience before buying a phone." The device will continue to be sold through retail stores, and other channel partners.
As of November 1, 2010 Google have closed the Nexus One support forums, redirecting users to the Google Mobile forum, which only has categories for software. The message shown to users was: "The Nexus One forum will be archived and become read-only on November 1st. Please see the Nexus One Terms of Sale for details regarding support. If you have questions about using applications on your Nexus One post them to the Google Mobile Forum." Also worthy of note is that the link to Terms of Sale on that message has no mention of support, contrary to what the message implies.
As of the announcement of Android 4.0, Ice Cream Sandwich, HTC has announced that there will be no more software updates for the Nexus One, as the hardware is now too old to run the new version of Android effectively.
According to Andy Rubin, the next Nexus series phone would have targeted business users and may have had a hardware keyboard. In July 2010, The Daily Telegraph reported in an interview with CEO Eric Schmidt that Google would not be releasing a follow up to the Nexus One.
Google officially announced the Nexus S on December 6, 2010. The device, built by Samsung, was the first to ship with Android OS version 2.3 "Gingerbread" and includes Near Field Communication (NFC) hardware.
