Vibration problem on JB

[micronz]

My XP has been experiencing no vibration oftentimes since when its still ICS.(sometimes its working but most of the time its not working, I already tried the service test *#7378423#* but still not vibrating. I also tried to restart it but sometimes it didnt work )
Now my xperia p is now on JB and still I experience this problem. I recently factory reset it but nothing happens.

Any solutions?

Anyone experiencing the same problem?

Haven't heard about this before actually. Since the problem still persist after the update I'd say you should try a software repair at first. If that doesn't help you should send in the phone to a service center so they can take a look at it.
