CyanogenMod is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. CyanogenMod does still include various hardware-specific code, which is also slowly being open-sourced anyway.

All the source code for CyanogenMod is available in the CyanogenMod Github repo. And if you would like to contribute to CyanogenMod, please visit out Gerrit Code Review. You can also view the Changelog for a full list of changes & features.

Known Issues (regarding latest available Stable build)

Please do not report bugs if it is already listen in the list of known issues

Current Audio HAL doesn't properly wake up audio devices from standby, causing issues with some VOIP apps. Check FAQ for Workaround -- WIP | Highest Priority -- #1

While in-call (on second call) using headphones/headset, audio could be routed to the Earpiece. Enable/Disable Speaker or Plug Out/In the Audio Jack to fix it. (Probably linked to #1) -- WIP | High Priority --

While in-call using earpiece the receiver will hear a little echo effect if volume is set to maximum. Reduce volume to fix it. -- WIP | Medium-High Priority --

After each boot Camera won't take pictures on first start. You'll need to close the app and re-open it to get Camera working. -- WIP | Medium Priority --

Wireless Display with some TVs (HDCP-dependent ones) could cause issues (AOSP bug related to HDCP. Google doesn't provide a solution) -- Unknown Status | Low Priority --

Rarely, when you wake-up the device, the touchscreen could have a noticeable input lag, easily fixable by turning off and on the display. (H/W or S/W bug?) -- Probably won't be fixed | Undefined Priority --

Reporting Bugs

First of all, read this: http://www.chiark.greenend.org.uk/~sgtatham/bugs

You are allowed to report bugs only in this thread. Before reporting a bug, please make sure you are running as stock as possible. This means no custom kernel, no custom framework modification, etc. If you are using any of the above modifications, please flash the rom again to get rid of the modifications before reporting.

REPORT BUGS IN THIS THREAD ONLY

Grab a logcat right after the problem has occurred. (Please include at least a few pages of the log, not just the last few lines, unless you know what you're doing.)

If it is a random reboot, grab /proc/last_kmsg. (Do not bother getting a logcat unless you can get it just before the reboot. A logcat after a reboot is useless)

If the problem disappears after running "setenforce 0" from a root shell, grab /data/misc/audit/audit.log

Remember to provide as much info as possible. The more info you provide, the more likely that the bug will be solved. The following is a useful format to follow. Note: If you can provide the latest night/build that the bug didn't exist, it would greatly help in tracking down what caused it.

What is your--
Phone model:
Radio (baseband) version:
GearCM version:
GearCM download url:
Google Apps version:

Did you--
wipe data/factory reset:
restore with titanium backup:
reboot after having the issue:

Are you using--
a task killer:
a non-stock kernel:
CMSettings/Performance Settings (other than stock):
other modifications:
Provide any additional information (observations/frequency of problem/last version it worked on/etc) as needed:
