Last night I had my BlackBerry Priv set to Do Not Disturb, Priority Only. This morning I saw there had been a Flash Flood Warning emergency alert that I had not heard. Testing the "Emergency broadcasts" settings on my phone using "Preview emergency notification" with Do Not Disturb turned off, it was loud. With DND on Priority Only, it was silent.
The Priority Only setting should not silence Emergency Alerts. I should not have to leave Do Not Disturb off, and hear a wrong number at 3 am in order to hear an alert for a Tornado Warning or Flash Flood Warning overnight.
Is this something Verizon can change, or is it part of Android that Google controls?
My Priv is Android 6.0.1, security patch level June 5, 2017.
