My initial thought is that this is the Samsung Plus app running.
Can you provide a screenshot? Does it say anything when you pull down your notification bar?

Mine just appeared yesterday. See top left plus sign and partial circle beside Bluetooth.
It could have been a change in the latest update or it could have been changed when it was placed in my pocket prior to locking the screen. Oops!
It appears to be an indicator for Data Saver, which is located in Settings/Data Usage and can be turned On or Off.

I't means Data Saver is turned on so videos do not automatically play like in Facebook for example.
