I found 'front-facing camera' to be ambiguous. When first reading it I assumed it means a camera facing forwards from the user's point of view when using the device. Later I realized it means a camera pointing backwards towards the user's face and what is behind.
Perhaps 'user-facing' or 'inward-facing' would be a better way to say it. And a camera which points in the same direction as the user's eyes could be called an 'outward-facing' camera.
P.S. the hobs on my electric oven were labelled front left, front right, back left, back right. Left and right were relative to the user, but front and back were the wrong way round relative to the user.
