I have looked everywhere for a thread that addresses my issue so if I am missing it, feel free to send me in the right direction. I have just switched to a Samsung Galaxy S4. I have changed the vibration pattern (under sound/ringtones and notifications), but it seems to only affect my notification for phone calls, not texts. I want the vibration to be longer than the two short bursts. I do not want to to download a 3rd party app for these reasons: if I download (for example) goSMS, the app does not give me the number of unread messages. Then I have to download a notification app and, slowly, the number of apps I need to correct something missing keeps growing. Is there any way to change the default vibration for text messages with out downloading any additional apps?
