I have never had this happen. I don't even think I have seen a thread here about this although threads get posted here like 20,000 times a day

Are you sure your not getting something (email, text, undelivered text, etc...) and you might have turned off the notifications/icon in the notification bar?

 

This is happening to me but it may be the bluetooth and other things connecting and giving me the notification buzz. I really wish you could assign different notification sounds to different functions.

 

Actually my eris did this one time before.
if you go to the eris section. type in phantom

it happened a few times but nothing major

 

phantom vibrations? might just be you and not your phone!

Phantom Vibration Syndrome – is that a vibrating phone in your pocket…?

 

lol i dont think it's me unless
i'm having auditory hallucinations.

my phone has vibrated and rung with no text or email...

and i never use bluetooth
so that cant be it

so i do second the OPS question...
