can I use my phone during this?/ How long should it take??
Happened to me last night. Yes, it takes a loooong time. It's the Android Lollipop update. You can use the phone during the download, but not during the update (best I can tell, anyway).
NOTE: When it reboots and seems to freeze on the carrier logo (I assume you're on AT&T like everyone else who's getting the update on their Alpha right now), don't panic...just let it go for a long while (fix a snack and take out the trash!). It's not frozen, but there's no indicator.
Lastly, there are several little resets and downloads and stuff that'll happen AFTER the main download.
Be patient!
