I apologize if this has been discussed. I went a few pages back and did not see anything. I am using a Galaxy S3 unrooted. Evem with the phone locked it is still possible to gain access to the drop down settings/notifications screen. Its a bit annoying on the stolen lock screen because the screen keeps covering it up, but if you just keep making the motion as it flashes it eventually drops down. The concern I have is that when the phone is locked you can just pull the notification bar down and disable the GPS and such. I know if they wanted they could pull the battery and accomplish the same thing. Just something I noticed.
Thank you for such a great product though and keep up the great work.
