turning off email preview on lock screen after update Galaxy S4 just updated to latest Android and now my email is previewed on my lock screen. Any way to turn this off?  I'm using Gmail. Thanks
Go into Settings > Sound &amp; notification > "App notifications" and set Gmail as sensitive (as shown here: https://youtu.be/GNFE-S42wgU )

If you want to prevent all apps from showing notifications on the lock screen go into Settings > Sound &amp; notification > "When device is locked" and set "Don't show notifications at all"
