Loaded the test app, and it works as intended. Toasts are deliciously triggered, while the lock itself responds smoothly to the touch.
Thank you for the feedback.
Fixed an issue where the movement could generate a trigger when it is initially on the outside of the landscape circle. Oopps. :0 Version 1.1
My only suggesting would be to remove the shadowing behind the lockscreen info.
1) the unlock boundary circle should.d be invisible until you touch the lock button.
2) on the phone version the semi circle needs to be abit smaller to make it easier to drag with one hand on the phone.
