Since GB update, my battery life seems worse. Much worse, and I don't think it is just because I'm running updates to apps and that sort of thing.
Also, it screwed up several of my contacts. For example, it shows a friend's FB image but has the wrong name. The wrong named person now shows up twice--once as the right person, and once as the wrong.
Another issue--I use Winamp as my music player. I also have Doubletwist mostly for converting videos when I download them from my PC. When I am in my car and use Bluetooth radio, they both start playing music, when before, only my Winamp would play when connected. Is there somewhere you set the preferred/default music player?
I had the same issues with Handcent and notifications, and the generic Android image showing up for apps but I just deleted them off of my home screens and replaced them again.
Hope a supplemental update will fix this minor stuff.
