I purchased 2 Lumias for my wife and I and hers has always been perfect. The first one I received couldnt be activated and then when that was fixed lost service. I quickly got a replacement and was all good. However just yesterday I picked up her phone and noticed that the vibrate on her phone was amazing! It was really a vibrate versus a death rattle that mine had always been. Now today im noticing that my vibration is barely a wimper.... anyone else have issues with vibration on their phones, any solutions?
