How can I get both sound and vibration at the same time on my Samsung S4? Need some help. I must have pressed something on the settings on my Samsung S4 because when I receive a chat or SMS the phone doesn't vibrate unless I turn off the sound.

So right now I have to choose to eıther have vibration OR sound and I want both at the same time.
In the Messaging app, click the left soft key and open Settings. Under Notifications, make sure Vibrate is checked.
