Good news, my phone didn't kill over!
I updated this morning & wanted to give it some time before I updated the post.
So far so good. Here is what I've noticed after the update :
The update added some apps I didn't have before, like one called "Pen Up". The lock screen clock widget looks slightly different. I noticed when I'm playing Google Music & I go to wake up my phone there's a widget on the lock screen that wasn't there before. The 4G icon in the notification bar has a slightly different look. The settings menu has a completely different layout. There are tabs across as opposed to a long scroll down menu.
That's really all I've noticed. My phone is still running great, no issues that I know of at this point.
**One more thing...the calculator looks different.
