[Google Pixel XL ROMs, Kernels, Recoveries, & Other] espionage724:
Just some relatively minor things I noticed so far with LOS 16 (lineage-16.0-20181221-UNOFFICIAL-marlin):

OEM unlocking option under Developer options: It shows the "Connect to the internet or contact your carrier" message even though my bootloader is already unlocked (I have what I assume is a VZW variant and had to do something to unofficially unlock the bootloader); Oreo/15.1 and stock 8.1 showed a message similar to "Bootloader is already unlocked"

Under About phone, the Device name "Pixel XL": It'll do the typo red-underline under "XL" if you scroll the Device name setting out of view and then back into view (go to the bottom of the page and scroll back to the top); it also does this for custom names too

Camera: It asks for access to location with the standard Android permission prompt, and then if that's denied, it'll also give a different in-app prompt for tagging photos and videos with location; Oreo/15.1 only showed the standard Android permission prompt and nothing else if denied, but I'm unsure if the in-app setting showed or not if the Android permission was allowed

Mobile network under Network & internet settings: For preferred network type, nothing is selected by-default (I believe stock has LTE by-default, but LOS 15.1 didn't have anything either; I have T-Mobile)

Model & hardware under About phone: No issue, but I wonder if there's an identifier that can be shown to determine if the Pixel is a VZW or Google/stock model

Trust agents under Security & privacy settings: It shows None, but upon tapping it, it shows "Profiles Trust Provider" as enabled; this also happened under LOS 15.1

Developer options: Enabling "Android debugging" caused two notification sounds to go off back-to-back (I assume once for the ADB notification, and the other when/if the USB connection re-initialized back to charging? I was connected to a PC with adb); there isn't any notification sounds at all on LOS 15.1

Status bar settings: Network traffic monitor is centered with no option to change it, and if the clock position is also set at centered, it overlaps the traffic monitor

Regulatory labels under About phone: Nothing is shown at all (this also happens under LOS 15.1)

Android version under About phone: Vendor security patch level is "Unknown"

Wi-Fi preferences: Turn on Wi-Fi automatically can be toggled, but I recall on LOS 15.1 that this option was grayed-out I assume because LOS by itself has no network agent or something (I don't use Gapps, but I believe they provide the thing for this setting)

Assist & voice input: The "Assist app" setting was set to None by-default, but there were still a bunch of settings present. After manually selecting the Assist app setting and selecting None, those settings disappeared.

Wifi Modify Settings: Scrolling past the new option for Metered connection and Proxy fields is difficult; scrolling on-top of them selects them; it's possible to scroll further down by being right on the edge of the box. Not an issue on LOS 15.1

There's also a few settings pages that switch to the bright/white theme by-default, but switch to dark/black if I go to Dev settings and force Night mode to always on:

Home settings

Trust (Security & privacy settings)

Mobile network (Network & internet settings)

But some apps don't change with Night mode set to always on:

App drawer It changed to dark after I changed the wallpaper

Phone

Camera settings

Contacts

Some questions:

Apps: I notice a few Verizon-specific apps. I don't use a Verizon SIM, but I (possibly) have a VZW-specific Pixel. Are these apps installed for all Pixel phones, or just the VZW model? The apps in-question are VZW_Multicast_MW, vzw_msdc_api, Vzw OMA Trigger, VerizonUnifiedSettingsDialog, and My Verizon Services. All exist on both LOS 15.1 and 16, but the last one (My Verizon Services) comes enabled on LOS 16, and disabled on LOS 15.1.
