What I've managed to test so far on d620r with the original posted build:
- auto-rotate does not work
- live display works only with default color temperatures. Cannot customize it. It says the adaptive brightness is off even when it's on
- battery icon style cannot be changed
- when adjusting brightness level by sliding the status bar the system freezes for a few seconds, but back, home and previously used apps buttons work
- backlight buttons values remain on default even after changing them
- wifi settings keep crashing when entering advanced settings
- camera works, can take pictures
- video does not work from both front and back cameras, looks like it wants to start recording, shows 00:00 and then nothing
- no problems with wifi or data connections
- receiving and sending texts just fine
- calling people seems to be fine as well
- when trying to add more tiles not all of the options I would expect to see in there are present, can't find it in the menu where to do that (maybe it's just me). I remember that working fine on cm13
- haven't had any unexpected restarts so far
