Is it possible to make such an application for Android?

Question

Android

The application adds to the standard phone settings a function that requires a password in order to turn off the smartphone completely. Those. if someone steals the phone, he won't be able to turn it off because he doesn't know the password, and the phone can be located.
Is it possible to do this?
And if possible, what kind of labor costs in man-hours are approximately needed for this?

Answer 1

What about the meaning? You can not turn off the phone with the button - pull out the battery, well, or do a hard reset. However, if you need to, then I think it will take enough time, because it is most likely that you will have to change the Android code IMHO.
