After the lastest update, my phone's vibration would went off randomly.
For example, I've chosen to have vibration while typing, but the vibration would went off itself after typing a few words.
Not only that but seems like the whole vibration system's down and there's ZERO vibration for a few minutes, no matter what key I press or restart the phone.
I've tried to use the Xperia Companion's repair fuction and that didn't help fixing this problem.
Would that be a hardware problem? Or it that just a system glitch that the repair fuction couldn't fix?
