My galaxy Nexus just keeps vibrating and I cant find a way to make it stop. I have changed my default notification ring tone to 'silent' and 'vibrate on notify' off, plus gone through every single app to change settings and I cannot make it stop. It notifies me when it has wireless, it notifies me when it does not have wireless, it notifies me when many wireless signals are available. It notifies me that I have failed to acknowledge prior notifications. Sometimes it notifies me for no apparent reason. This must stop! It seems to have picked up a lot in the more recent updates. I only want to know if I have a text message or a facebook message. That is it, and I have those enabled at the app level. Nothing else. thanks!
