there is nothing ground breaking with this update.. actually.. it is a little faster.. battery life.. i havent seen any improvement..
there are more things about it.. i dont like than i do.. my main thing.. is.. when accessing the notification bar.. from the lock screen, and clicking my messages.. it doesnt go to the app..
other than that.. nothing spectacular.. but no bugs other than that..
if you have to have pictures next to your messages in text.. then dont do it.. cuz mine dont work either..
Edit: my list of issues
Cant get Gmail to not vibrate on notification, unless its on silent
notification bar, while locked, wont go to text app
when bluetooth connects, in my car.. my phone has to vibrate, and send a notification.
