Nokia has launched a new Windows Phone 8 smartphone in London this morning. It’s called the Nokia Lumia 925 and is described as ‘a new interpretation’ of the Nokia Lumia 920.

Unlike the previous flagship device, the Lumia 925 is lighter and has a partly metal body along with an AMOLED screen.

HTC has announced a new flagship phone using its HTC One brand rather than the rumoured M7 codename. The new HTC One runs Android on a Qualcomm 1.7GHz quad-core processor and has an aluminium body containing a 4.7-inch HD screen.

There’s a strong audiovisual focus to the new HTC One, with the company introducing three new features: HTC BlinkFeed, HTC Zoe and HTC BoomSound.

Huawei has announced a couple of high-spec smartphones at CES 2013 today.

The Huawei Ascend D2 is an Android device with a 5-inch 1920x1080 display, 13 megapixel camera and a 1.5 GHz quad-core CPU.
