So, updated to pr1.1 last week, everything was fine, until a few days later when i started getting a few bugs

1) For some reason, the nokia start up music no longer plays....

2) Also, I had an error on my lockscreen. I locked the phone, and the app grid faded slightly, but no lock screen appeared.... The faded app grid just stayed there.... .When I tried to use the app grid nothing happened. So the phone was in fact locked, but with no lock screen
