It has a 2 megapixel built-in digital camera digital camera with autofocus, 20x digital zoom, integrated flash, macro mode and the ability to record high quality video(532x288 MPEG-4 video with AAC-LC audio). The phone has no vibration feature. The screen swivels through 270 degrees so that the phone can be handled in a 'video camera' style.
It uses the Series 60 2nd Edition, Feature Pack 3 user interface and the Symbian OS 8.1a operating system. Recent revisions also ship with Version 2 of the Lifeblog software.
The N90 does not have a built-in hard disk drive like the Nokia N91 but it features 31 MB flash memory and is usually packaged with a 64 MB or 128 MB in-box DV- RS -MMC memory card. Nokia continues its recent tradition of bundling a USB data cable with the phone, previously an aftermarket item priced close to US$40. A 1 GB memory card allows storage of four hours of video on the handset
