Taiwanese company HTC has announced that there are some delays holding up production of its new flagship phone, HTC One.

The company promises that it will attempt to fulfil pre-orders by the end of the month, but the device may not appear in retail stores until sometime in April.

The reason for the delay is not specified by HTC. However, tech website CNET speculates that it is most likely because of the new all-metal case: apparently it takes 200 minutes to machine the thing for each phone.

This is a shame for HTC to experience lag in the availability of the smartphone, especially a powerful deviceis coming really soon from Samsung dubbed as the Samsung Galaxy S4.

Last month, Taiwanese mobile manufacturer HTC unveiled its latest handset that will battle head on with the titans in the smartphone market.

The HTC One is powered by Google's Android, but the company has distinguished it from rivals by using new software to replace icons on the home screen with a personalised stream of news articles, social networking updates, photos and video.

The new smartphone from HTC wowed critics and reviewers at the launch events in New York. The new handset offers a 1.7 GHz quad-core processor; Near Field Communication; LTE mobile broadband; stereo speakers; a big, 4.7 inch screen with a 468 pixel-per-inch resolution; and a 4 "ultrapixels" camera.

HTC is one of the most sought after tech company after releasing powerful and high quality devices over the years. HTC released successful smartphones in the past such as HTC One and HTC Desire series.

Initally, the handset was said to be available in March in 80 countries around the world, including in Australia. Vodafone, Telstra, Virgin Mobile and Optus are all listed as carrying the device. However, the device is still available for pre-orders on various carriers.

After the March release date, it is expected that the device will be available through resellers as well as online retailers. Thus, be on the lookout for deals and discounts for the new HTC handset.
