[Verizon LG G3] sireebob:
Loving it... Thank you for this! I find the experience overall much better than stock, even at Alpha! Everything seems to work, too, with minimal adjustments and issues. Definitely don't want to go back...

For those of you who'd like some info before taking the plunge, and for general feedback, here are some of my observations so far re: the 12/26 version / Lollipop in general:

This ROM feels much snappier than stock 4.4.2! Home screen and app switcher in particular have less lag. Various apps also feel snappier... TitaniumBackup seems to load its list of apps much more quickly, for example (but Firefox is still... Firefox). This snappiness is the big win for me.

No instability so far, once it's up and running! Been about 24 hours. See Caveats, however...

HDMI (SlimPort) works out-of-the-box, and it works perfectly so far, including audio (no sync problems I can see at all). I wasn't expecting this to work in an AOSP(A) ROM! This is also a big deal for me.

PCMark Work Performance benchmark is significantly higher: 4137 here vs 3507 on stock 4.4.2. Performed both tests with Tasker disabled, Airplane mode on (but WiFi still on).

No HW acceleration for some codecs, tested solely with MX Player Pro, with and without custom codec; however, the processor is so good that SW decoding handles any video I throw at it so far, without a hitch. Differences vs stock 4.4.2: MX Player's HW+ mode won't work at all. MX Player's HW mode performance is poor for some videos. One of my test videos which was unwatchably slow on HW: H.264 High L4.0 1920x818 23.976fps 2490kbps. Stuttered a bit on stock but much less. (Again, plays perfectly with SW, even with HDMI, on both stock and AOSPA.)

3DMark graphics benchmarks were visibly slower, but not hugely so (~13% lower score). Also tried with HDMI, which reduced the score by ~23% (didn't try with HDMI for stock). Graphics-only scores: AOSPA / AOSPA+HDMI / Stock 4.4.2; 3DMark Ice Storm Extreme: 9030 / 6925 / 10338. Performed both tests with Tasker disabled, Airplane mode on (but WiFi still on). Physics scores were comparable, trending towards *higher* scores for AOSPA, but all over the map, really...

Wishlist: Dark theme would be great eventually, but I don't think there's a custom theme engine for Lollipop yet? I really wish there was a way to get on-screen volume controls from the notification dropdown, and put the screen to sleep as well. Lollipop doesn't allow you to customize the quick settings. Power menu access without using the button would be nice too.

The few caveats re: this ROM (12/26) / Lollipop in general, that I've found:

My phone has gotten stuck on the boot animation 3-4 times out of probably ~25 reboots (an estimate). I'm not sure yet, but I think it's sometimes related to using the 'reboot' terminal command instead of rebooting normally, but it seems like it's had problems even without that, occasionally. I can tell it's going to get stuck if the screen doesn't dim, and the animation doesn't pause, and it's been more than a minute... And when it's stuck, I have to take out the battery and reinsert.

In any case, it's still worth sticking with the ROM for me, since I don't reboot that often, and the odds are pretty low.

Cellular service was not working for me at first. Out-of-the-box, it wasn't trying CDMA (Verizon, PagePlus [what I use], other mvno's) and I couldn't find a way to force it to do so with built-in tools. However, I used Toggle Network Type 5.0 (thanks cygery!) to set it to CDMA and EvDo (auto mode), and this got things going fine. I don't have LTE service, but if you do, you can choose an option that includes LTE, or perhaps you won't even have this problem. Before adding the widget, I had to allow external access, and I told the app to show all network types.

Charge-only mode doesn't work for me, and pops right back to MTP. Haven't experimented much with it, though.

Xposed still not available for ART (for *any* Lollipop ROM), so it's harder to tweak some things.

Can't enter diag mode, so can't change certain EFS/NVRAM settings using PC tools.

Haven't been able to find any dialer codes that work.

SELinux Enforcing meant I needed to change some things via supolicy to get TitaniumBackup to access /mnt/media_rw/sdcard1 (so that I could use the Protect feature). PM me if you'd like to know how I got this to work.

Harder to find working apps to remote control the phone itself. LG On-Screen Phone can't work anymore, due to API changes with one of the libraries it relies on -- Google changed a function signature, and removed the one it depends on. Not sure if it ever worked with AOSP, anyway, but the offending LG OSP library would need to be fixed and recompiled (that, or the GUI framework would need to have the function added back as an overload! Good times...). I don't think it's even open-source...

Not sure if this is related to the ROM at all, but around the time of starting use of this ROM, my Music folder on my external SD card (exFat) started showing up as empty, and I couldn't put any files in it either. Hooked it up directly to the PC with a card reader, created a new folder (Music2), moved all the music into Music2, deleted the old folder (Music), and renamed Music2 to Music. This resolved it once I put the card back.
