The Nokia N81 is a smartphone announced by Nokia on 29 August 2007 and released the next month.

The N81 was marketed as a mobile gaming device, similar like the 2003 N-Gage. It was the first device that came preloaded with the N-Gage 2.0 gaming service in 2008 (albeit in public beta), and it came with 2 dedicated gaming keys that can be used for N-Gage games and other applications. During the launch of N-Gage, the N81 was specifically chosen by Nokia in advertisements. The N81 is notable for being the only N-Gage 2.0 device with special gaming keys.

Variants[edit]

An 8 GB version of the Nokia N81 was also available. The only difference is the lack of the Micro SD slot. The phone treats the 8 GB as a Micro SD, while keeping about 25 MB of it, to itself.

Problems[edit]

The Nokia N81 suffered from lower sound output due to the release of the new firmware version. According to Nokia, they must follow an international standard wherein a device's initial or default volume must be set to low to avoid any damage to its users.

Reviews[edit]

Cnet found it buggy, slow, and badly designed.[1] Mobile Phones UK gave it 3/5, praising its feature set, while again criticising the "plasticky" design.[2]
