The newer haptic feedback API that is used instead of the vibrator
service since ef03dfe doesn't work for everyone.
The new vibration option allow to choose both the newer API ("system")

This activity points to the system settings page for enabling input
methods. This is purely a shortcut but is expected by many users.
It could be made more useful in the future or hidden whenever the

A new option changes the "change_method" into the new
"change_method_prev". It switch to the previously used input method.
A long press on "change_method_prev" sends "change_method".
A new section is added in the settings and existing options are moved.
