Hey. I had some problems with vibrations recently - they did not want to work at all. Eventually, after installing a few roms and kernels, I had to give my phone to the repair service. They managed to fix the problem (or did they ? The phone had some better moments when the vibrations were broken, so maybe they just let it "rest" and found out that it's working again). Anyways, after a week or so, I have the same problem. I had my phone overclocked to 19-729Mhz with SmartassV2 governor. After restoring the default setting, after around 4 hours the phone has it's vibrations back. My question is - is there any connection between those two things ? Maybe the phone gets too much heat and somehow stops the vibrating thing ?
