Huawei has announced details of its 2012 financial results ahead of the audited figures due in April.

Global sales revenues for the year are expected to reach 220.2 billion Chinese Yuan (£22.3 billion), up 8% on 2011, while net profit is expected to be up 33% to CNY 15.4 billion.

Nokia has launched its third Windows Phone 8 device, the Nokia Lumia 620. It’s a smaller, lower-price smartphone than either of the company’s two previous models.

The Nokia Lumia 620 has a 3.8-inch display, a 5 megapixel camera, NFC support and a battery that promises up to 9.9 hours of talk time.

Samsung Electronics has completed a review of suppliers based in China after a report from China Labor Watch criticised working conditions at one of Samsung’s Chinese suppliers.

CLW said that child labour appeared to be a common practice in one factory, also noting that it had additional concerns about working hours, employment contracts and working conditions.

HTC has announced quarterly revenue of NT$70.2 billion (£1.49 billion) and net profit of NT$3.9 billion. Profit was down 79% year-on-year, while revenue was down 48%.

China was described as a key driver of growth for HTC in Q3 2012.

Can you trust a Chinese company to build a telecoms network?  Apparently not, according to the US House of Representatives. The “Investigative Report on the U.S. National Security Issues Posed by Chinese Telecommunications Companies Huawei and ZTE” wasn’t at all impressed with the two companies, although most of the complaints appeared to be about a lack of cooperation rather than hard evidence. I wonder if any mysterious agents are planning to visit the new Huawei UK HQ before next year’s official opening?
