HTC One X flat
The One X comes with a quad-core 1.5GHz processor and a 4.7-inch, 720p HD full-touchscreen display.
In ZDNet UK's testing, the combination of the quad-core processor and 1GB RAM made the handset one of the most responsive Android devices to date, with no lag in opening apps or quickly swiping between home screens. It was also free of animation jitters, which are present on some Android devices.
Naturally for a top-of-the-range handset, it comes with all the usual smartphone staples of HSPA, Bluetooth 4.0 and Wi-Fi connectivity. On-board storage is limited to 32GB, but the phone comes with 25GB of free Dropbox storage, integrated into HTC Sense, for two years.
