Hardware


The Nexus One has a 3.7 inch AMOLED screen with PenTile matrix pixel arrangement.[33] The stated resolution is 800x480 pixels, however a research article claims that the resolution of 653x392 pixels would better describe its PenTile RGBG display, being the "effective resolution that is comparable to the way pixels are counted on a standard RGB-striped LCD display".[34]

The capacitive touch screen is capable of handling limited multi-touch gestures.[35] It has an illuminated trackball which can emit different colors of light ****d on the type of notification being received. A voice processor developed by Audience uses a second microphone (on the back) to reduce background noise during phone conversations.[36] 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 2.1 + EDR, and 802.11b/g WiFi capabilities.[37] The Snapdragon processor allows for many advanced capabilities including 720p video playback.[38][39] There is built in hardware decoding for H.263, H.264 and MPEG-4 video, and is capable of playing MP3, AAC+, Ogg Vorbis, WAV, and MIDI audio, and displaying the 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 64 gigabytes of card storage. Applications can only be installed to the 512 MB internal flash memory, of which 190 MB are available for that purpose. During unveiling, it was mentioned that Google may eventually lift this restriction after addressing security issues.[30]

A third party analysis by iSuppli estimates the cost of hardware components to be around $175.[38][39]
[edit] Cellular


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 also came along with UMTS frequency bands 1 (2100 MHz), 4 (1700 MHz), and 8 (900 MHz).[40], allowing it to access 3G throughout Europe, as well as on T-Mobile USA and WIND Mobile in Canada. The second version of the Nexus One 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.
[edit] Software

Main article: Android (operating system)

The Nexus One runs the Google Android 2.1 operating system. The 2.1 firmware version of the Android operating system adds a few aesthetic changes, such as "Live Wallpapers", which are animated and can react to different user inputs. It also replaces the "Application Drawer" with a single button which can be pressed to access the list of applications installed on the phone. This thumbnail list can be scrolled up and down and, as it's scrolled, the applications roll up into a 3D cube instead of disappearing from the screen. Once the bottom of the application thumbnail list is hit, the screen bounces off similar to the iPhone functionality.

The integrated Media Gallery, developed by Cooliris, provides several new features allowing the user to browse, edit, and share p***os and videos on the phone. The Media Gallery and ***browser display with 16-bit colour rather than 24-bit[33].

On February 2, 2010 announced an over-the air update for the Nexus One.[41] It adds pinch-to-zoom functionality to the *** browser, gallery, and maps applications. In addition it adds Google Goggles natively and fixes many of the 3G connectivity issues reported by T-Mobile users.

The Nexus One will be able to play Flash content when Adobe Systems releases Flash Player 10.1.[42]

As of March 2010, Android-****d phones have access to more than 34,000 applications through the Android Market
