The Nokia N97 is a high-end smartphone introduced on 2 December 2008 by Nokia as part of its Nseries and released in June 2009 as the company's flagship device. The N97 was Nokia's second S60-based touchscreen phone, after the Nokia 5800 XpressMusic. The device features slide-out QWERTY keyboard, and runs on the Symbian v9.4 operating system. Its design takes cues from the Nokia N79. A smaller and lower-cost variant, the Nokia N97 mini, was later released.
