Sony Ericsson posted a loss of €207m for Q4 2011 on sales of 9 million handsets. This is down from 11.2m Q4 2010, a 20% YoY decline. More cost cuts / job cuts are expected, unfortunately.
Declining volumes is a growing market means Sony Ericsson's smartphone market share is likely down to lows not seen since early 2010.
The good news is this is the last quarter as Sony Ericsson, and perhaps Sony can do more to use wireless synergy across devices. But this will be a challenge for Sony, a company that is already challenged on so many fronts.
