GS4 White Blocks On Lock Screen

[Firestorm421]

Every now an then I turn my phone on to see white blocks instead of characters on the lock screen. It only effects the lock screen and is remedied by restarting the device. Any idea what the cause might be.

Maybe something is corrupt. Have you tried a factory data reset?
