I have noticed this on all the 4.4.2 kitkat variants I have tested.
I found that grabbing the latest rom for your region and then flashing that and performing a full wipe sorted my issue when I had it.
Also, make a backup in Kies as this makes it slightly less painful to do.
It sent me round the twist, but luckily it is much better now!
