Have a line across the locked screen?

[tazlondon]

Have a line across the locked screen, 1cm down from the top. It started a week ago?

Default screen, where PIN is required.

Any ideas how to remove it, without resetting the phone, as I have alot of apps installed.

Bought the phone brand new, and it's two months old.

Thanks

Disable any active alarms in the clock. After that... no more line
