Three days ago I updated my Galaxy S3 with Android 4.3 Jelly Bean. So far no serious problem, but a little thing I can not solve it. I can not change the shortcuts on the lock screen. I was confronted with a friend of mine with S3 with 4.3, going to 'Settings -> Device -> Lock Screen' he is a switch that allows you to enable or no shortcuts, and change them. To me there is not I first did a wipe, then I updated via Kies official firmware of Samsung, but to me there is no such function. How can I fix?
