Better

• Faces in front of a bright sky are recognised better. A doorbell looking out at the sky
  often sees a face that is nearly black; its light is now evened out before it is compared, so
  you are named sooner and other people look less alike.
• It asks more when it is not sure who someone is, so answering teaches it how each camera
  sees you: from a lower similarity (with SFace), several times in a row while someone walks up
  (a few seconds apart, up to five), and right away again after you answer.
• After importing a sensor that recognised faces, the app says that face recognition is off
  on the new sensor and opens its Settings tab to turn it on.
• The text of Ask me about faces I do not know says what it does.
