Owner Information on Galaxy S3 I just had a software upgrade on my Samsung Galaxy S3 phone. The Android version is 4.3.

How do I update the owner information on the locked screen?

There is no option under "security" in the setting.
From SM: Go to Settings → My Device → Home Screen Mode and select "Standard Mode", then hit "Apply".

Next, go to Settings → My device → Lock screen. All will be active now.
