I uploaded a screenshot below. Its the blue circle. The inside cursor in it is green but i think its another color because the screenshot was made in whatsapp.

Welcome to Android Central! If this is your phone, wipe down the notification panel and look for more details there.

If this isn't your phone, I suggest you contact the owner of the phone and ask them.
