HTC has unveiled a new version to its flagship smartphone, the HTC One, which features an improved camera, better battery life and motion sensing technology. 

Launched last year, the original HTC One has proven a significant success for flagging manufacturer HTC, winning a number of awards and positive reviews around the world. 

However, the company is struggling to compete against other handset makers in the ever more competitive smartphone market, and reported a worse than expected net fourth-quarter profit for 2013 in early January.

The new handset, which will retain the HTC One name, has a redesigned body with a 5 inch full HD (1080p) display. 

It also has double rear facing camera feature, called Duo Camera, which will allow the user to apply effects and change the focus of an image after it is taken.  

Among a string of other new features, the camera can also capture slow motion video.

Inside it is powered by a Qualcomm Snapdragon 801 processor with 2.3 GHz quad-core Krait CPU. It runs on the latest version of the Android operating system, 4.4 KitKat and is fourth generation network compatible. 

Among the other new features is Motion Launch, a series of in built motion sensors that allow the user to interact with the phone without turning on the screen, like turning it on with a swipe and answering a call by putting the phone to their ear.

The phone also boasts a battery that HTC claims lasts 40% longer than its predecessor. 

Available in three colours at launch – grey, silver and gold – the HTC One will be released in Ireland on 3 April.
