Dealers last week said the Nokia N97 was experiencing significant software issues, with the device freezing and switching off.
They also said it has a fundamental design fault, that the camera lens scratches when dust gets under the cleaning cloth on the protective slide.
Nokia said: “We’re not experiencing widespread returns or complaints and it is still creating a great buzz. The N97 has been through extensive testing. As with all Nseries devices software upgrades will continue to be available.”
