How can i change text vibration on my Galaxy S3? I want to change sms vibrations on my Galaxy S3 but I can only change it for incoming calls.
Can someone tell how to change notification vibrations for sms on my Samsung Galaxy S3?

Thank you in advance. 

PS : I am using Hangouts.

Edit : If possible, I don't want to install an app to solve my problem.
In Android each application can control the notifications itself. So if you turn off vibration for calls, texts will still have the option, and so on.
In the case of Hangouts:

Open the application.

Swipe from the left to open the menu (technically it's a navigation drawer).

Tap &quot;Settings&quot;

Tap &quot;SMS&quot;


You can enable/disable vibration here:

If you wish to change the intensity/duration/pattern of the vibration you either need an SMS app that supports this feature or root access to your device coupled with a custom kernel that allows this feature.
Alternatively (though you specified you don't want to) you could try an app like Vibrate tools and see if that fits your need. I have not tested this app.
