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:

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.

CM 12.1 Nightly 4/19 is solid so far

roaringcrown · Apr 20, 2015

Agreed. Easily, daily driver stuff. I really haven't found a hiccup yet.

Dadud · Apr 20, 2015

bluetooth disconnect is still present in 04/19.

Small issue--just tried to unlink my Notification volume from the Ringtone volume--the slider moves---no change. Can someone else check that & see if the same happens...if so it looks like a minor bug.

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.

does the voice messages of Whatsapp are working?

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?

Does bluetooth still disconnect on screen lock?

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.

On-body detection didn't work for me on 04/19 build. I set my phone down for a few mins and it didnt lock like it was supposed to.

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

kickassdave · Apr 21, 2015

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.

Wifi is, I think, the biggest regression from AOSP (with battery life)
I dont know how to report such a bug efficiently, but I hope this can be fixed!

leonard.pitzu · Apr 21, 2015

bluetooth is also an issue. actually it's bt/wifi issue - tthey are linked to each other.

hoangphamvm · Apr 21, 2015
