Had one issue yesterday, but I'm not sure if it's related to the OS or the theme. I did a search on Google Maps and called the place from the map result. I got a "would you like to allow google maps to access the phone", said yes, but the box never went away and had to reboot. Also, I'm using Calix's Titanium Today theme and one text message will not go away. Again, this may be related to the theme though.
