I have a Galaxy S 8+. I recently stopped receiving notifications for texts and calls. I have to go into my messages or call *86 to see if I have a message or voicemail. Notifications are set to on in settings.
I'm here to help make sure you get all notifications back to your Galaxy S8+. I would be lost without my notifications. Have you recently downloaded any new apps or software? When you say you are missing notifications from calls, are you meaning you don't see a missed call notification? From my understanding, you are not receiving notifications from texts & voicemails as well. Is this correct? If not, please provide other details.
