The worldwide mobile phone market grew by just 1% year-on-year in the second quarter of 2012, according to the International Data Corporation Worldwide Quarterly Mobile Phone Tracker. However, the volume of smartphone sales grew by 42.1%.

IDC has calculated that 406 million mobile phones were shipped in Q2 2012, of which almost 154 million were smartphones.

Customers on the Three UK network have more than doubled their monthly mobile data usage within the past year. Last summer, average use by ‘pay monthly’ contract customers was 450 megabytes per month - but the figure is now up to 1.1 gigabytes.

Three offers ‘all you can eat’ data options on all of its tariffs, pointing out that most other UK smartphone users are on a tariff with an allowance of no more than 1GB.

Everything Everywhere has published interim results for the first six months this year.

Service revenue for the six-month period until the end of June 2012 was £2,989 million. That’s a 1.8% drop year-on-year, although removing the effect of Ofcom’s mobile termination rate cuts would show a 3.1% increase.

Samsung Electronics has announced its quarterly results, publishing a revenue figure that’s up 21% year-on-year to 47.60 trillion Korean won (£26.6 billion). Net profit was up to KRW 5.19 trillion.

The company’s Mobile Communications business reported a 75% increase in earnings, with revenue reaching KRW 20.52 trillion. Handset shipments were said to be up quarter-on-quarter and year-on-year, although specific figures weren’t published.

Facebook has reported financial results for the second quarter of its financial year. This is the first quarterly report since the social network floated on the stock market just over two months ago.

Revenue was up 32% year-on-year to $1,184 million - up from $895 million in Q2 2011 - but net income dropped to a $157 million loss. The loss was mainly due to the cost of staff share schemes; without this, profits would have risen from last year. Around 84% of total revenue came from advertising.
