N o matter what i have done I can't get sms notifications sound or even a number on messaging app of how many if any messages are waiting on my s9 ph.. I just found 11 messages that I was not notified of.. it just cost me over $4000 as I didn't message back and they got someone else to do the work. Not happy at all ..
There has to be a fix for this somewhere but I can't find anywhere.. notification settings on ph are all on ..nothing on Optus.. should have stayed with vodaphone I'm thinking..
Solved! Solved: Go to Solution.
Have you looked under Settings -> Notifications -> Messages -> Toggle Off/On
and Settings -> Notification Sounds -> Messages Notifications -> Toggle Off/On and choose the sound
If that all looks fine, have you tried putting your SIM in a spare/borrowed phone to see if the same thing happens? Is the latest software installed? Extremely doubtful it is a network issue.
