How to use the front camera on the Samsung admire from metro pcs?

The Samsung Admire does not have a front-facing camera. There are two little "lense" looking things to the left of the ear piece, but those are external light sensors for when you use the auto screen brightness feature. When that feature is enabled your phone will use those light sensors to dim the display and conserve battery life when the external ambient lighting conditions are darker. When you're in a bright room or outside the phone will increase brightness for better visibility.

Hope this helps.
