Nokia is widely expected to unveil its first tablet computer later this year when Microsoft's new Windows 8 operating system becomes available.
"Nokia's fate in tablets is directly linked to Microsoft, which also has to succeed in this space," said Pohjola analyst Hannu Rauhala.
Nokia has lost out to Apple Inc and Google Inc in the smartphone business and is now pinning hopes of a turnaround on Lumia, a new range of smartphones which use Microsoft software.
