Lollipop: secure lock screen menu options This is just an extension of the previously asked question.

I have upgraded Google Nexus 5 with android 5.0.1 Lollipop.

We can toggle wifi, data, flight mode and other options from locked screen.

Is there any way to secure or customize which of these menu options should be displayed?
Short answer: you can't.

There are several bug reports like this one. I'm using Android 5.1.1 right now and this security problem still exists. This "bug" makes the Android Device Manager useless if your device gets stolen.
