Nokia has launched the Lumia 925, its new flagship smartphone running the Windows Phone 8 mobile operating system. The Finnish manufacturer has unveiled the device, which comes equipped with a 1.5GHz dual-core processor, 1GB of RAM and 16GB of internal storage, as part of a dedicated Lumia event taking place in London. It has a 4.5-inch AMOLED display – Nokia’s brightest to date – at a 1280×768 resolution, and should be readable both in bright sunlight and at obscure viewing angles. The device is also much slimmer than its predecessor, the Lumia 920, coming in at just 8.5mm thick and 139 grams. It’s undoubtedly one of Nokia’s most attractive smartphones to date. The device also has an 8.7-megapixel rear-facing camera with Carl Zeiss optics – the same as the one found in the recently unveiled Lumia 928.
