HTC has unveiled its new flagship smartphone, the revamped HTC One, as it attempts to regain lost market share.

HTC launched the device in New York, a week before the start of the Mobile World Congress.

The phone uses Google's latest operating system, Android Jelly Bean, and features a 4.7in (12cm) 1080p high-definition display.

The body is made fully of aluminium and has front-facing stereo Beats Speakers

It hopes that new software features will help to make its new handset stand out.

One of them is BlinkFeed, personalised content on your home screen, that - according to HTC - "aggregates the freshest content from the most relevant sources as identified by you”

HTC also boasts that its "ultrapixel" camera and software produce the best low-light shots available on any smartphone camera, challenging companies such as Nokia.

Another feature, called HTC Zoe, captures short high definition videos instead of still images before and after the camera shutter is pressed, so that users can chose the best picture to capture the moment. The software can also turn a gallery of still images into a collection of mini-videos.

The Taiwanese company will be pinning its hopes on the HTC One and that both its hardware and software innovations can help it to regain ground lost to Apple and a bevy of rivals using the Android operating system, in particular Samsung.
