Alright, since I resurrected a couple of NAND-bricked 16GB P31x0 ...
Bug 1: Tap on the "User image" in the notification shade - and try to set a avatar image for the "Owner" account - system crashes and reboots once you tap the "Save" button where you can crop the image you selected.
Bug 2: YouTube doesn't work overly well. When you start playing back a video it plays for 2-3 seconds then "stutters" and gives a "playback error". You can retry at which point it will work, but it's annoying (doesn't happen with the July/2 CM13 build). Also, YouTube only shows up to 480p in "Quality" where in CM13 it shows 720p (landscape full-screen).
Bug 3 (not sure if bug or "feature"): You can set the "Recent app" thingy to display "full screen" (no navbar / statusbar), but you cannot enable "extended desktop" anywhere for the UI itself.
Bug 4 (not sure it is a bug): I see a rather strange behavior on system boot...
- When I "shutdown" and have it plugged into the charger it shuts down, then the "charge anim" shows up and the screen is cleared but the backlight isn't turned off.
- When I start the system (from "shutdown" state) it seems as it does a "double boot" ... Galaxy Tab logo screen -> blank -> "reboot" (?) -> Galaxy Tab logo screen -> blank -> Omni boot anim.
All clean flashed with Delta's latest "base" Gapps package and SuperSU 2.65
I'll also slap a post into the CM13 thread as I see two minor problems with the latest build as well.
