Updated Samsung Galaxy S5 to Marshmellow now text messages won't vibrate or display preview.

I just updated today, and ever since text messages won't vibrate, even though it's in vibrate mode. Every setting i have says it should vibrate when i get a text, but no avail. When i first set phone to vibrate it will do that little vibrate thing, but once it's on, nothing.

Also my phone doesn't do that little preview thing anymore. You know the one when you get a text it displays it line by line on the notification bar.

Any tips besides factory reset?

For the preview, check the Notifications in Settings. The options are Show All Content, Hide Sensitive Content, and Do Not Show Notifications
