iphone 4 problem black screen and it doesnt stop vibrating
Mar 21, 2011 The screen stayed black and it kept on vibrating. I tried holding down the lock/power key for a few seconds to turn it off completely, still nothing. I plugged it into the computer, hoping that iTunes will reset it, but iTunes didnt even recognize that its plugged in. Aug 10, 2014 The phone wont turn on its just a black screen. I plug the charger in and the phone vibrates and repeats this vibration every couple of seconds. Any Ideas what is causing this? there seems to be a few instances of this online. people having the same problem and a mixture of diagnosis. Some are saying its the screen connections / the screen itself.
