[Verizon Samsung Galaxy S III] SlimSnoopOS:
I was sidetracked with some things in life, lovely snowstorm, and I'm a little slower than others with my bug reports BUT I have been running this the entire time since I posted. Hold onto your butts.

For the most part, SlimLP Feb 7th build has been running well for me. I clean flashed (wiped system and data) and am using the VRBMF1 firmware with VRUDNE1 modem. Also, I flashed SuperSU v2.45. Quick breakdown on what works/does not work. Calls, sms, MMS, 3g/LTE all work for me. What does not work: stock camera (known Lollipop issue) and GPS. I have not been able to test Bluetooth nor NFC. Long winded version follows!

Calls: I live in an area with low signal and I had no issues with calls 5 mins to a few hours. I did not notice any issues talking over the phone. Incoming and outgoing calls work fine. I often talk on the phone with Skull Candy earbuds and I did notice that I cannot adjust in-call volume. It just doesn't seem to decrease for me.

Sms/mms: sms mostly sent fine for me in a range of locations including the DC metro. Initially, sending mms seemed to take a few minutes but over the course if a few days I think it sends in a consistently normal amount of time. Receiving mms is working well.

GPS: Never seems to lock on for me. Perseus you know this from my beta testing. I can get an initial lock however it does not follow me as I drive nor does it consistently lock in while navigation was running. There were a couple times when GPS locked onto me after I had driven 10-20 mins down the road with navigation just running. I tried rebooting, reflash, wiping caches in recovery, and I also use GPS Test to see if satellites ever lock but they never did.

Audio: works mostly fine but there were times when I noticed ringtones/notifications would not go off because they had reset. For the most part, ringtones and notifications rang whenever they needed. I also noticed that sporadically, my alarm or audio when watching a video clip (say a vine or instagram in the browser) would play just static instead of the appropriate audio. The most jarring was the alarm having this occur once, however it is not easily repeatable nor is it consistent. This occurred for one alarm in a 9 day span, but this occurred more frequently when watching a video in the browser or app. For reasons that should be clear, you are most likely to observe this if you view many random clips or videos in apps whereas your alarm likely only goes off once a day so it's less likely to occur with the alarm. I have a hunch that this may also be tied to the issue of ringtones/notifications being reset sporadically because after noticing this audio static issue, I think this is when I noticed my notifications or ringtone were not playing. If I reselect notifications/ringtones, I don't think I noticed the lack of ringtone/notification sound again on a text or call until the next time I had the random audio static bug.

Odds and ends. I less 4 random reboots over the span of 9-10 days on this build. I usually when 25-40 hours between reboots or manually initiated reboots. Three days ago I flashed BMS beta kernel from Feb 3 and I have had no change in issues since flashing. Your mileage may vary with custom kernels. Root apps work for me. I use Light Flow, Titanium Backup, ES File Explorer, BetterBatteryStats, and Wakelock Detector with no issues. Lastly, I restored texts from a previous build of SlimLP and I restored about 20 apps using Titanium Backup.

I want to say that is everything I have noticed since flashing this build. My bad for the delay for anyone who was waiting on my reply.

Edit: One more thing. I edit my build.prop to enable the Lollipop soft keys and also to switch the capacitive back and menu keys. I have done this on each and every beta release and I have no issues with any of these edits nor with muktasking. These all work perfect for anyone who likes to make these specific edits like I do.
