Hi Anyone still having problems with the black screen? Have downloaded and installed the ota update and if anything the problem is worse! Seems ok on incoming calls but if I make an outgoing call the screen goes blank and the only way to reactivate is to hit the power key. This is starting to sound like faulty hardware to me. I read that the ota update was supposed to sort this! Any advise would be appreciated as other than this really annoying problem the phone is great!
