HTC has finally announced one of the worst kept secrets in the technology world, the HTC One smartphone. The firm's new flagship device, previously called the M7, will launch confusingly as One next month. See also HTC One specs.

"People today immerse themselves in a constant stream of updates, news and information. Although smartphones are one of the main ways we stay in touch with the people and information we care about, conventional designs have failed to keep pace with how people are actually using them," said Peter Chou, CEO of HTC Corporation. Take a look at New HTC One / M7 smartphone launch: as it happened too.

"A new, exciting approach to the smartphone is needed and with the new HTC One, we have re-imagined the mobile experience from the ground up to reflect this new reality."

The HTC One features a 4.7in screen with a Full HD (1080 x 1920) resolution. That means a whopping pixel density of 469ppi, higher than the Sony Xperia Z's 441ppi. The handset runs on Android 4.1 Jelly Bean with HTC's Sense 5.0 user interface.

It's powered by a 1.7GHz Qualcomm Snapdragon 600 quad-core processor with 2GB of RAM. Storage options are 32GB or 64GB.

Sense 5.0 includes things like BlinkFeed, a personal live stream of information and BoomSound, aka stereo speakers with Beats Audio.

Something a bit different is the UltraPixel camera which can apparently gather 300 percent more light than other smartphone sensors. A strangely named feature called HTC Zoe captures images before and after the button is pressed.

Connectivity consists of Wi-Fi, Bluetooth 4.0, NFC, DLNA, 4G LTE and the HTC One also has infrared so it can be used like a regular remote control.

The HTC One will launch in March on a number of UK mobile operators including O2, Three, Vodafone and EE. Phones 4U will also be selling the handset.
