After disabling Samsung Messaging because of a pretty nasty bug (https://gizmodo.com/a-bug-in-samsungs-default-texting-app-is-sending-random-1827291759 …) I've not gotten any emergency alerts. Sucks that I have to choose between emergency alerts and a messaging bug. Can't find if that bug was ever fixed.
For bunnies and those that like them. Non-bunnies will receive complimentary bunny ears.
