While the One S (pictured above) shares many of the same specs as the X, it is highlighted by its 7.9-millimeter profile. The processor is a more traditional dual-core Snapdragon from Qualcomm, while the display is 4.3 inches at qHD resolution. RAM is the same 1GB as the One S, but built-in storage is only 16GB. The two phones share the same camera, as well as a Bluetooth 3.0 radio, Wi-Fi b/g/n, and the usual complement of sensors.
Both the devices will have Sense 4.0 and will come with 25GB of Dropbox storage integration. Both the smartphones will roll out in late-March, early-April.
