CyanogenMod is a free, community built, aftermarket firmware distribution of Android 5.1.x (Lollipop), which is designed to increase performance and reliability over stock Android for your device.

Code:

 * We are not responsible for bricked devices, dead SD cards,
 * thermonuclear war, or you getting fired because the alarm app failed. Please

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. You will need to provide your own Google Applications package (gapps). 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 our Gerrit Code Review. Your changelog is whatever was merged into gerrit.

Just flashed cm12.1 4/20 from CM12.0 4/15. Flash went fine, booted-up and got to the "optimizing apps" screen. I walked away for a few minutes, and now, the screen is completely black and unresponsive. :crying:

I'm stilling getting an issue where I lose LTE/data connection and it requires a reboot to resolve. Is anyone else seeing this? I'm still able to text and receive voice calls, but nothing but a reboot will reconnect data. Even toggling airplane mode has no effect. Just see the signal strength bars with an "!" character indicating data is disconnected. I had the same issue with CM 12.

I had the same problem w/ 4/19. had to revert to cm12. I'm assuming its because of the firmware. I'll have to update mine and retry. I dunno if that would help you.

Update: upgraded firmware and now im good on 4/20.
Edit 2: getting fc on gapps, used both official and minimal, what's everyone using?

Everything seems to be running pretty smoothly. The on problem that I do have is that the system seems to be having a hard time automatically connecting to wifi. It's fine as long as I stay in range of the wifi, but when I leave and then come back, it takes a while to connect. Sometimes I even have to disable and reenable wifi before I can get it to connect.

Running 0420 build on AT&T full wipe:
I'm having an issue with connecting bluetooth with my car. Seems that it connects but once it tries to enable reading the text messages it crashes. I turned off reading text messages for now and it works. Any ideas?

If you're S-OFF flash the dev edition 4.4.4 firmware and reinstall. i had the same problem with my sony headunit. havent had a problem since downgrading.

I can second that. For me connection to WiFi sometimes must be forced manually.

Not encountered any bugs yet but have to say this is easily the smoothest experience I've had in ages on a a ROM (20/4)

I'm pretty darn picky when it comes to fluidity of a ROM and this is right up there with Sense/GPE.
