Removing an icon on statusbar How can I get rid of the sun icon on the top left of the statusbar???

I've checked my wether apps, and it doesn't belong to them.
Since you are using Samsung and I presume you're on version 6.0, go to Settings > Notifications and toggle off All Apps. Now activate the notification for every app, one by one. This way you may find which one is responsible for the sun icon.
