?!!!
Since running an update of some sort yesterday, my unlock button doesn't work. If I press it enough times, something might happen, but it doesn't unlock the phone, or lock it predictably any more [the lock unlock screen may appear for a blink and then go again].
I don't think it's the button as it was working 5 minutes ago and I've not dropped/mashed it in that time.
I am only able to unlock the screen if I take the battery out and reboot it.
Anyone else have the same issue? I'm on a Nokia 620.
Worst case scenario download the Nokia Software Recovery Tool and run that.
I have a Lumia 925 and have had the Glance Screen update all all seems to be running fine(so not much help really).

I have a workaround.... Use the camera button to wake it up!
Thanks for the input, Uno
Bump... Any one else?
