Welcome to AC
What buttons changed? Is the Arabic keyboard at least showing? Some updates change the placement of some of the more common buttons on the keyboard. If they are moved, the only real option you have is to look for a keyboard that has the layout you want since you can't downgrade your OS to get back to the old keyboard layout.
