Yes your are certainly right that all that is patentable.
My rant is addressed to the awakening pattent watch dogs that might be reading.

Software or specific usage patterns inherent to a certain technology..Good luck avoiding that overlap between "patentable" and what is supposed to be logic usage following a certain key technology.

And when something good gets going we have to fear the awakening patent watch dogs backed by their oiled law suite machine..

With the toilet example I'd point out that it shouldn't be patentable if a chimp given the device can figure it out (double tap or swipe).

Now I am off to check If I can secure my patent on all geometrical shapes to unlock, square, triple tap, swirl to unlock Morse code to send SMS and do simple things from lock screen w/o screen backlight on (army) and customizable app specific touch gestures on an overlay.
