The DROID 4 update to build 6.13.219 that we first reported on last week is rolling out now. If you did not manually update using our file, then you will want to head into Settings>About phone>System updates and pull it. It’s a smallish update at around 18MB, but it does include a new MotoCast widget, improved battery life, and better keyboard backlighting management.
Here is the full changelog.
Cheers J, Bob and @daryls61!
