NITDroid N9 status
« on: February 22, 2012, 01:02:58 am »
What is working:
- based on Android Open-Source Project (AOSP) v 4.0.4_r2.1 (IMM76L)
- Google Applications (GApps), PlayStore (Android Market)
- dualboot kernel (without reflashing), ability to choose OS after power on.
- N950 supported (see
- 3D drivers, OpenGL, hwrotation ("fake" default portrait mode for landscape-oriented displays), livewallpapers
- touchscreen (multitouch)
- hw buttons (volume, power), Nokia N950 keyboard
- ECI accessory (headset buttons)
- USB networking
- lcd off in sleep mode, colour profiles, electron beam effect (demo:
- alarm driver, RTC
- mounting MyDocs as "SDCard" [realized; NOT FIXED, but HACK EXISTS]
- basic video decoding (sw) and playback, youtube
- wifi (only basic functionality: able to connect to AP, linkspeed/RSSI (signal strength) indication. no tethering).
- basic CellMo functionality: network registration, USSD, SMS, data (GPRS/EDGE/3G), signaling. Actually, ofono/ofono-ril stack is used: all things that it able to do on the n900.
- bluetooth (scanning, can pair devices. I'm able to send files between SGS2 and N9. I didn't test deeper.).
- battery status, charging indication
- sensors: accelerometer, compass
- audio: playback (audio routing to: loudspeaker, headset or earpiece), jack switch in kernel (h2w), beta-quality microphone support (voicesearch, shazam/soundhound, skype, some sound recorders - ok)
- lights HAL (lcd brightness, hw keyboard lights(Nokia N950) )
- root access (via adb shell; su/Superuser.apk)
- fakeGPS (ability to trick system and set any location as GPS fix), no real GPS support yet!

Not working:

Work in progress:
- PR1.3 compatibility
- rework audio HAL to use tinyalsa (done); fix headphones routing (broken after tinyalsa rework; done) ; better microphone support
- improvements to hwcomposer HAL (done); get rid of horizontal scrolling glitch (done)
- voice calls (experimental, proof-of-concept-quality; no microphone support yet)
- touchscreen sensitivity issues done
- sort out ofono problems: can't answer on incoming call (fixed), DTMF appear to be broken

Important, but not critical:
- Cleanup source code, commit all changes, allow AOSP-like builds.
- RIL/ofono: connectivity problems on some operators. Advanced features: PIN/PUK (un)locking, roaming etc.
- Android USB drivers: adb, mtp etc.
- sensors (als, proximity etc)
- sensors: compass (calibration)
- lights HAL (led)
- audio (a2dp, microphone (attempt to record mono/8000Hz crashes mediaserver)
- HW video decoding (DSP)
- vibra (postponed. It's very likely Android to get support for input/forcefeedback devices in JB 4.1)
- camera
- GPS. GlonASS also ;D
- NFC (n9 share the same nfc chip with crespo: pn544 from NXP. I suppose we could use crespo's HAL/kernel modules with minimal changes, no need to write it from scratch. However, it doesn't work atm ( userland problem ) ).
- a lot of other things
