Samsung 'has problems despite its big profits'

Despite Samsung expecting yet another big rise in quarterly profits, the Korean mobile phone to TV giant still faces a number of problems, an analyst has told the BBC's Asia Business Report.

Jasper Kim, of Asia Pacific Global Research Group, pointed to a recent ban on sales of its Nexus phone in the US following a patent dispute with rival Apple.

The big concern is whether this could have a knock on impact on Samsung's new Galaxy S III handset.

This issue has contributed to recent declines in Samsung's share price.

In addition, Samsung has struggled to keep up with demand for the S III.
