OK, last night I started gettings some FC's. Never had one since I got the D2 so I thought it could be related to the update. So I reset my D2 and when it came back on it was in super slow mo. I couldn't scroll through my apps. Definitely not good. And it wasn't getting better.
I never recommend a battery pull. I seriously don't think they help.
I was wrong. I was getting to do a factory data reset when I decided to pull the battery. I had it out for a few minutes because I was doing other things. When I got back to it I put the battery in and it started booting up without starting it. I gave it a few seconds, and now everything appears normal.
If you do have any of the issues I described, give it at least a 30 second battery pull. I think it will fix it for you.
