Since a couple of days ago my phone has started to constantly and irregularly vibrate as if I got a notification. This starts to happen as soon as I unlock the phone and goes on until I lock it again. Aprox 5-40 vibrations a minute. It is very annoying as it stops the sound of music and videos every time it vibrates. There are no damages to the phone (it is kept in a really sturdy case). The phone is updated to the latest version. Please help!! Best regards Victor
