The camera on your smartphone may be intended for taking photos, but it has other uses as well. 下面是三个例子:  

  1. If you’ve misplaced your glasses and can’t see far-away objects, view the room through your phone camera to get a clearer picture of your surroundings.
  2. Hold your camera up high, 低位, 或以上, 下, or around furniture to take video or stills of areas you can’t easily see on your own.
  3. 没有镜子? 没有问题. Look for spinach in your teeth.
