Lately whenever a missile is fired upon us, I receive cell broadcast alert about it. In my area of living the city alarms are working loud anyway but the cell broadcast sound is extremely alerting and is over stressing my 3 years old kid.
I looked in the menu (Settings -> More -> Cell broadcasts) but and I found I can make it sound for only 2 seconds (instead of four).
I would like to keep the cell broadcast but change the tune. any ideas how can I do that?
