Note that the N950 is the developer device for the N9, thus not much different in ways that would require porting or special adaptations.

Nokia N950 phone hardware specification
=======================================

Nokia N950 phone uses same hardware components as the Nokia N9 phone
with the following exceptions:

* N950 is physically larger and is made out of aluminum, whereas N9 has
a polycarbonate unibody.
* N950 has a physical slide-out QWERTY keyboard. The N9 is a touchscreen
-only device.
* N950 has a 4” TFT LCD display whereas N9 has 3.9” AMOLED display.
Display resolution is same on both devices (854x480). Due to the use
of different display technologies, developers should avoid one pixel
with 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).
* N950 has a different physical camera module than N9. Both camera
modules have very similar image quality (Carl Zeiss branding in N9)
and both modules support 8Mpix image mode.
* In the N950 the front facing camera is in top right corner and on N9
it is in the bottom right corner. The actual camera module is same.
* N950 supports Bluetooth version 2.1+EDR, whereas N9 supports
version 4.0
* N950 does not have support for NFC
* N9 has slightly more sensitive magnetometer and ALS
* N950 has 1320mAh battery, the N9 has 1450mAh battery
