What is the little icon next to the time on my login screen for? Looks like a horse / chess knight. Searched for other screenshots and it's there too so it's obviously meant to be there!
You might notice a chess knight icon on your Lock screen to the right of the screen. This was added by the Lock screen team so they could tell via screenshots if someone was using the new Lock screen or the old one, and will eventually be removed in a future build.
