Google has unveiled the Samsung-made Nexus S, successor to the HTC-made Nexus One.
The Nexus S includes new NFC technology and runs Android 2.3.
Inclusion of near field communications (NFC) technology indicates Google's plans for the Nexus S to make contactless payments.
Google has also backed Samsung's Super AMOLED display, which it claims is four times more visible in sunlight than the Nexus One.
Samsung's integration of ARM's latest generation of Cortex A8 into silicon through the Hummingbird 1GHz processor also makes the Nexus S faster than its predecessor.
