Attention, this page is UNDER CONSTRUCTION and still holds many incorrect facts copied over from N900 template. This warning will get removed once all those incorrect copies are corrected or cleaned out

The N950 is the second Maemo / Harmattan device which can be used as a phone. It is a development platform for the Nokia N9.

It is only available to developers, and not as a consumer product. It shares much hardware with the N9, with the notable differences that the display is TFT, not OLED, and there is a hardware keyboard.

[edit] N9/950 differences

Feature N950 N9
Size Larger, Aluminium case.

124 x 60 x 14 mm

Smaller, Polycarbonate one-part case.

116.5 x 61.2 x 12.1 mm

Input devices Slide-out keyboard Touchscreen only
Display (854*480) 4" TFT, AU Optronics, (864x480 limited by software to 854x480) 3.9" AMOLED, Samsung or LG
Camera 12MP (Toshiba HES7 Series) 8MP Carl Zeiss
Front Camera (identical) Top right Bottom Right
Bluetooth 2.1+EDR 2.1+EDR
NFC No Yes
Compass and Accelerometer Less Sensitive More Sensitive
Battery 1200mAh, 1320mAh or 1400mAh 1450mAh

Due to the use of different display technologies, on the N9, developers should avoid one pixel width fonts(?) and graphical objects with lines one pixel wide. Also avoid the extensive use of bright colors, especially white, when developing for OLED displays as this increases the power consumption (typical for OLED displays). See this page on common OLED pixel arrangements for more info

[edit] Features

[edit] Accelerometer: LIS3LV02DL

Sysfs attributes under /sys/devices/platform/lis3lv02d/:

  • position - 3D position that the accelerometer reports. Format: "(x,y,z)"
  • rate - read reports the sampling rate of the accelerometer device in HZ.
  • write changes sampling rate of the accelerometer device.

Only values which are supported by HW are accepted.

  • selftest - performs selftest for the chip as specified by chip manufacturer.

By default output values are scaled between -32768 .. 32767

[edit] "freefall" device

It supports blocking operations, poll/select and fasync operation modes.

You must read 1 bytes from the device. The result is number of free-fall interrupts since the last successful read (or 255 if number of interrupts would not fit).

[edit] Software

The OS is maemo-6, codenamed Meego-Harmattan. The core OS still is maemo based and unrelated to though APIs and the UX are in some cases similar to meego_proper.

Nokia seems to refer to this device as N9-devkit:
