Face tags on the Samsung Galaxy S3 and are neat features of the Gallery app. When you take photos of people, the app places yellow boxes over their faces, then allows you to tag them by tapping on the yellow boxes. However, if you're not interested in using face tags, the yellow boxes can be distracting when viewing your photos. Disabling face tags prevents the yellow boxes from appearing. Here's how to disable them:
Step 1: Launch the Gallery app and select a photo to view.
Step 2: Tap the Menu key and select "Face Tag."
Step 3: Tap on the "Off" selection.
That's it. Now your photos will display without the yellow face tag boxes.
