I've had this phone for just 2 months and for some reason my phone just doesn't vibrate which is quite annoying when on.silent.mode. It did vibrate at first but has just stopped. I have checked all settings and all relevant ones are on. Any ideas guys?
Then it could be a hardware issue, repair your phone with SUS and check again, if not then take it to a Sony repair center

It dose be the problem of the hardware. You can take your phone to the sony service center to check the motor vibrator like that. Then repalce with a good one.
