You can't force stop that App info. It just kills the window but the "Phone settings" is still active. Killing that in the task manager, and it's back in a few minutes. I haven't gone the "turn off the sound" route because I want this gone.
Also, I notice that if my alarm goes off, the Phone Settings screen pops up instead of the screen to dismiss the alarm.
I enabled dev options, and looked at running services,but nothing outstanding there...
