A.B.C (Anti Butt Call)

Pocket dial, pocket call, purse dial, butt dial, butt call, bottom call.... name it the way you want, it's just annoying! There is nothing more embarrassing than calling or messaging someone by accident. This app will prevent that without interfering with your normal use. You will not notice the app is running.
Unlike other apps made to prevent unwanted phone calls, this one doesn't change the way you make calls and doesn't lock your phone when you don't want.
The detection system will be enabled only when your phone or messaging app is running, and the protection will be activated only if the phone is upside down or if something is close to the top of the screen (like when you put your phone in a bag or in your pocket).
I originally made this app for my father and brother who are very good at butt dialing, but I think it can be useful to many people.
