/**
 * A "forced" EN US Numeric keyboard designed solely for SMS code entry. This
 * "upgrade" over KeyboardView will ensure that the keyboard is navigable via
 * TalkBack and will read out keys as they are selected by the user. This is
 * not a perfect solution, but save being able to force the system keyboard to
 * appear in EN US, this is the best we can do for the time being.
