These are functions I use everyday：switch voice mode, turn off screen, mobile data connection，wifi on off and reboot.
For convenience，I put them together to make this widget. I wish it is helpful to you.
switch sound / vibrate / silent modes
mobile data connection on off
WIFI on off
reboot (only for rooted phones)
Before uninstall, please go to "settings"->"security" (or "Location & security")->"Select device administrators", uncheck it from "Device administrators".
Android 2.2 above.
