Dial *#0*# or open the member app to the right tab and diagnose it. And see what you got. And did you see it in any app like WhatsApp, or is this only dial app that defaults one with green dial. Then check the galaxy store for updates. If not, wait for the security patch. Or use Google dialer. If you see it in all dialers, then may b it's a hardware issue. Go to the service centre.
