Hi, I've owned Samsung Galaxys for many years and am well used to the settings. I'm having an issue where intermittently I do not get a notification sound when I receive a text message or WhatsApp, but do when it's an email or system message. It then returns to normal a day or so later. It's not the do not disturb feature and the numbers aren't blocked. Has anyone else experienced this? I'm loathed to do a factory reset but a setting reset didn't work.
Tia
