Samsung Galaxy s20 5G / Since the most recent OS update (One UI Android version 12), I no longer receive notifications for texts. My settings allow for them & have remained unchanged. "Show Notifications" & "Allow Sound and Vibration" are selected. I use the standard text messaging app & have checked every notification setting in-app & in the broader notification settings yet nothing has resolved the issue. There is no sound, no vibration, no floating notification, or icon badge when receiving an SMS. The display only lights up for a brief second. All other app notifications seem to be fine, just texts are doing it.
I have noticed that when I turn the ringtone volume setting down to vibrate, when notifications should also vibrate, it shows the vibrate symbol but it is dimmed out (appears to be muted) when before it was the same as the ringtone.
