My S20 randomly stops making sounds for notifications, texts and phone calls. The fix provided by Samsung is to reset "Network" settings found under "General Management" I need to do this 3-4 a year, randomly, nothing to do with updates. Clearly a problem with their device that not been addressed for years. Worst part is that you loose all your saved Bluetooth devices, This is the kind of stuff that makes me consider going back to the Apple universe Boo on Samsung!
