Hardware
The Nexus One features a 3.7 in (9.4 cm) active-matrix OLED display (480 x 800 px, WVGA) with a 100,000:1 contrast ratio and a response time of 1 ms. Despite being capable of multi-touch, this is not enabled by default in the US version. It has an illuminated trackball which can emit different colors of light based on the type of notification being received. The phone has two microphones, one on the front and one on the back, to enable noise cancellation to reduce background noise during phone conversations. A standard 3.5mm headphone jack is also provided.
The phone features a 1 GHz Qualcomm 8250 processor, 512MB of RAM, a 4GB microSD card, 512MB of internal flash storage, a 5.0 megapixel auto-focus camera with LED flash and digital zoom, GPS receiver, light and proximity sensors, Bluetooth 2.1 + EDR, and 802.11b/g/n Wifi capabilities.
