Nokia, the world's top cellphone maker, has said that some of its flagship N8 smartphones were sold with a power fault that meant they switched themselves off.
Nokia sales chief Niklas Savander said "a limited number of N8 users" were facing the problem of their phones switching off, and they are not able to turn them on again.
A spokesman said the fault was due to a problem in production, which has since been fixed.
The fault in the power management stems from the way in which the engine component -- which includes most of the technology in the phone, excluding covers and batteries -- in the Nokia N8 was being installed.
"If you look at the total number it is a small number," Savander said in a video on company website.
