HTC has unveiled a new smartphone to sit alongside their existing flagship device, as the Taiwanese technology giant looks to revive its struggling fortunes.

The new phone, the HTC One A9, will come with the new Android operating system - Marshmallow - which is set to launch in the coming weeks.

It will also feature an all-metal body in two initial colours, as well as a 13-megapixel camera and high-resolution audio speakers.

The smartphone maker confirmed that it would be a "mid-range" device, accompanying rather than replacing their premium One M9 device.

The design has already been compared to that of the iPhone, with HTC looking to gain a market share after a turbulent year which has seen the firm cut 15% of its workforce after a quarterly loss of more than £8 million.

The technology giant's chief Cher Wang said: "HTC is a smartphone pioneer, having delivered the first Android smartphone, the first Windows smartphone, the first 4G smartphone, and the first all-metal smartphone.

"Today we're taking that heritage of innovation to the next level, unveiling a phone that stands apart in a market increasingly dominated by a company which controls every aspect of your phone.

"The HTC One A9 breaks from this trend by offering an incredible design, fantastic performance, cutting-edge software features and the freedom to take full control of your smartphone experience."

The new phone has a 5in full HD screen, as well as fingerprint scanner and the ability to create hyperlapse videos.

The camera software also supports the RAW format that is used by professional photographers in the image editing process, which HTC says will enable users to take and edit photos in more detail on the device.

During a live event to announce the phone, HTC also confirmed that the One A9 would be coming to the UK at the beginning of November.
