Phone malfunctioning after update

[chandhu]

Once I upgreded my phone, its display won't get on even I pressed on screen ON button. and another problem is with walkman. In locked screen, music keys are not working. The lock screen is blinking if the walkman is ON. Is there any way to solve this issues??

Thanks in advance.

Do you have smart key app?

Thanks for your reply. I know smart key will work for walkman in lock screen. My problem is the lock screen is blinking if walkman is on, My intention is to avoid that not to go prev, nxt and play/pause in walkman.

I was suggesting to remove smart key,see if that helps.Or try settings-apps-all-walkman,clear data.
