For some odd reason, my D2 will not vibrate when I receive a notification (ie new text message). It vibrates for everything else like phone calls, etc.
In settings I have Setting> Sound> Vibrate> Always selected. Also I use GoSMS and made sure vibrate is checked there too. I thought at first it was a GoSMS issue so I re-enabled the stock MMS app with notifications and still no luck.
I am running Liberty 1.5, Gingerbread Theme, and came from a full SBF and wipe data/cache.
On a side note, has anyone had any luck with the Silent State option in the sounds settings? It says it will "Add a silent state for complete silence to volume control" but I have not been able to get that to work in Liberty 1.0 or 1.5.
