The screen flickers and then I cannot control the lock screen widget. But the main problem is I cannot add music widget to the lock screen as in the list of widgets that I can add it does not show walkman 
Thus to do any thing with music including volume control or play or pause I have to unlock the phone through my pattern lock.
Just wait for the latest update to be approved and released in your country
or
Manually update your phone
problem solved after firmware update!!!!!
Great news
