I have a HTC Desire 526. When I first got the phone, I would get a "tone" alerting me to an emergency alert. Yesterday we had severe weather in our area and I received the emergency alerts but the phone did not make a sound to let me know about the alerts. Does anyone know what/where I need to look to correct this? I have checked in the Emergency Alerts App and I am signed up for the alerts. Thanks for the help.
