In the arms race that is smartphone manufacture, HTC has unveiled the equivalent of the BFG from Doom: a quad-core Nvidia Tegra 3 processor, running at 1.5GHz per core; a 720p hi-def screen; Beats-bolstered audio; an 8MP camera with an aperture of f2.0 for noise-free images and an impressive bag of tricks, including HDR stills and 1080p video. As with all Tegra 3 devices, this NFC-toting, Ice Cream Sandwich-flavored Android boasts a Battery Saver Core that portions out power depending on the apps and components that need it, which is just as well; you're going to be spending a lot of milliwatts showing it off.

Screening calls

The One X's 720p screen is a bright, 4.7in 'Super LCD2', fronted by Gorilla Glass, naturally. Perched just above it you'll find a 1.3MP camera for video calls.

Double team

The One X's 8MP camera is a true multi-tasker. While shooting a move, you can also capture a still; or take a full-res screengrab while watching the video back.

Skinny love

At half a whisker over 9mm thick, the One X just gets into the Skinny Club; not bad for a phone with as much processing power as an Eee Pad Transformer Prime.

 Over capacity

The HTC has a one-size capacity of 32GB. Prety generous, but if you're after more it also comes with 25GB free cloud-based storage courtesy of Dropbox.

Stop making Sense?

This is the first HTC we've seen with Android 4.0 from the get-go; given the great job HTC's Sense interface has done skinning previous Androids, we have high hopes for it.
