4. Samsung Galaxy Nexus
One of the first devices to be shipped with Android 4.0 Ice Cream Sandwich, the Samsung Galaxy Nexus is not only a great looking smartphone, it's among the world's purest Android devices. Its 4.6-inch curved super AMOLD screen conforms to the face during conversations and automatically blacks out. When withdrawn, its stunning 1280 x 720 pixels blink instantly to life.
Measuring 2.7 x 5.3 x 0.3 inches, the paper-thin unit weighs just over five ounces. You'd never know that underneath is a 1.2-GHz dual-core processor running on 1 GB of system memory plus 32 GB for storage. Its five megapixel zero-shutter camera with continuous focus records video at 1080p. There's also an LED flash 1.3-megapixel front-side camera and two mics. Galaxy works on LTE/CDMA and WiFi networks, includes Bluetooth and NFC radios, and gyro, accelerometer, compass and barometer sensors. Very cool.
