MOBILE phone maker Sony Ericsson has posted a second consecutive quarterly profit, thanks to smartphone sales.

The world's fifth biggest handset maker, owned by Ericsson and Sony, made a pre-tax profit of 31m euros for the second quarter ($39.7m; £26m).

The firm lost 283m euros in the same quarter in 2009.

Smartphone devices, which have PC-like functions and links to social networking sites, have reawakened consumers' appetite for gadgets.

But the company says it still expects only slight market growth this year.Competition in the key smartphone segment is intense.
