I'm having some trouble getting my HTC Desire to vibrate for notifications. The phone will vibrate fine for incoming calls, and it does the test vibrate if I set it to vibrate-mode, but it won't vibrate for any incoming notifications.
Notifications involved include incoming texts, incoming email, facebook updates and meebo messages.
I definitely have all of the above apps set to vibrate for notifications.
The vibrating worked fine a few days ago, but seems to have failed after the battery level dropped to nearly empty. Is there a global setting that disables vibration for apps? I've searched but can't find it.
Failing that, would a factory reset have any chance of fixing this? I'd rather not have to do that, but if I do is there an easy way to save and then reload settings such as home page setup? I'm aware that there's an app for backing up installed apps.
