I was unable to find directions specifically for the Xiaomi Redmi. For example the only answer to this similar question Emergency alerts: is there any way to silence the "severe threat alerts" and "Amber Alerts" while I'm sleeping? shows an App "Emergency Alerts" that does not exist either for the asker or for my Redmi.
So I have been trying to stitch together directions for other android devices - here is the closest I could find:
Apps | Messages | Notifications . But There is no
Emergency Alerts there.
It is on android 9. Any help on this would be appreciated.
