[Galaxy Note II Original Android Development] fwmone:
Thanks! I think I found the problem: I disabled tone as well as vibration notification and only used LED notification; that's what I did with Cyanogenmod 12.1 in the past. It seems not be working, though - after enabling vibration, LED notification is working again. Although I don't like vibration notification, I can live with it (I've got a flip cover and close it when I want to stay focused - by opening it, blinking LED shows me new messages at one sight).

That being said, now to the always upcoming question: After using it one and a half week, I think yes, it is stable and a good daily driver (thanks a lot, tilaksidduram - great job!). After using several versions of Cyanogenmod on my Note II for now over four years (never used the original ROM), it's definitely the best ROM I've used so far. The last one I used for a long time was https://xdaforums.com/galaxy-note-2/orig-development/cyanogenmod-12-alpha-1-n7100-t2949644 which I was very satisfied with, too (great job and thanks again, Ivan_Meler).

Now to the things I found out or solved for me, maybe it helps others too:

Battery life is great; see attached screen shots. It's about the same as with above given Cyanogenmod 12.1, where I got up to 6 days of usage time.

LineageOS finally supports aptX! See my post here: https://xdaforums.com/galaxy-note-2...-cyanogenmod-14-0-n7100-t3487568/post71657824 - it's like my headphones were born again. Thank god, it's something I always missed on Cyanogenmod since I'm listening to music a lot.

Speaking of audio quality: When listening to music via Bluetooth and having the display off (using Poweramp), sound stutters every now and then by having small gaps. This is a problem older Cyanogenmod ROMs before 12.1 had, too, and I solved it by setting the CPU governor from pegasusq to ondemand (setting audio player to a higher priority or enlarging the buffer didn't help). In the past, I used SetCPU for this, but this app seems not be working on our ROM. So now I'm using no-frills. As far as I understand, the difference between pegasusq and ondemand is, that pegasusq is aware of multi cores and can handle them individually thus giving you better battery runtime. It looks like pegasusq seems to throttle the CPU too much sometimes which leads to above mentioned stuttering. Cyanogenmod 12.1 had this solved, maybe by using some kernel tweaks. Anyway, if you're facing the same problem, just try ondemand. I don't know how much battery time you're losing - to be honest, I never felt any difference.

I had a lot of problems regarding performance and battery runtime when activating Google location history. It kept my phone active several hours a day and used a lot of CPU time. After disabling it, the phone's performance and battery runtime is great again.

Speaking of location: GPS is working great and stable on 20170324.

Suffering from disconnecting camera (can't take photos but need to restart your phone)? I had this one time only up to now; anyway, just try "restart camera" (https://xdaforums.com/galaxy-s3/themes-apps/17-fixed-camera-app-lib-cm-aosp-roms-t2505973) - worked in the past on all Cyanogenmod versions I used and works on this as well.

I saw MTP host crashing like all you others did too - but even when it crashes, you can continue using the phone and accessing storage. Not a big deal, I think.

LED notification seems not to be working when display is off if you disable tone and/or vibration - see above.
