KWE App has built-in face recognition functions. When you take a picture or choose a picture with two or more faces, KWE app will automatically mask all of the faces. Tap the face you would like to reveal. You can also add mask manually.
To change to smiley face or pixelate:
- On the home screen, swipe to the right and select “Settings”
- Click on “Face mask type” and choose one of the two options.
