How can I turn off the home screen preview of SMS/text messages in my Galaxy Note 2 On an Android device (Galaxy Note 2) with a locked screen whenever an SMS is received it's preview is displayed over the locked screen. This is super inconvenient - anyone who is nearby can see it without even unlocking the screen.Is there a way to disable those previews over a locked screen?
i have been annoyed by this as well!!

even after turning off as mentioned above i was still receiving the notification and preview of the msg

my problem turned out to be an add on sms widget for evernote "sms to evernote" that gives you the option to send your sms to evernote.

It is not obvious from the pop up that it is evernote 

there are two options in the "sms to evernote" settings 

"Enable sms pop up"  when you enable this you get further options to "hide sms in pop up" 

The "hide sms in pop up" option does not work you get the preview regardless

it took me a while to work this out and i hope this saves someone else some time :-)
