So, 24 hours with the new build.
Yesterday, most of the day, I ran my 920 with the new build, a hard reset, and no WiFi while at work. When I got home I was able to get a Fast Track update for the build, and finish reloading.
A couple of us noticed App updates not completing when the screen went to sleep. After the second update that seems to have been fixed.
Overlays are still very glitchy with anything that seems to 'float' or hover over, like the notifications/actions area, the 'slide down to power off', the task switcher, and any keypad including the lock screen pin pad.
6tag hung for me, requiring a reboot, but it seems to be working now.
Base functions (phone/text/music/bluetooth) seem to be working.
Some status icons at the top, Cell/Wifi/Battery disappear at times. I would love to see the battery meter at the top every time I look at my phone, but I have to swipe from the top to see it come back. Not sure if this is by design or not.
Battery life seems pretty good after getting a full charge yesterday. I'm gonna unplug it now and run it today to see what I get.
