Interesting find and thank you for bringing this to our attention.
1) Re: the FEMA alert tomorrow - Know that should a frequency be sent, turning your phones off or throwing them in a Faraday bag will not do anything to help... or hurt you. think about it logically. Your phone is constantly RECEIVING signals from towers and does not emit any frequency that is different than what is emitted from the devices on the towers. These towers have been and do emit harmful frequencies CURRENTLY. It makes no sense to think that they would broadcast ahead of time a specific time/day that they plan on "activating" some new frequency that will potentially trigger the crap in people's bodies from the jabs. THEY ARE ALREADY DOING IT.
I believe the hype around this is nothing more than clickbait fearporn and every single person I know who's familiar with this type of technology AND is very much aware of the Graphene Oxide in people's systems, agrees. I believe the FEAR people have is more potent than any signal sent from a tower as well. This said, should you feel more comfortable walking away from your home/phones and going out into nature barefoot to ground and enjoy the sun, DO IT! We should all be spending time doing this every day regardless, so perfect excuse to get outside and make it happen. You'll still, unfortunately, be subject to the constant radio frequencies the towers around us are sending all day every day. Having a device nearby will not change this.
2) It is frustrating that some of the permissions are locked and we are unable to uninstall this app entirely. I believe it's a requirement of the FCC for devices that connect to national phone/sms service providers to have this app set the way it is. This said, the Wireless Emergency Alerts app on Android devices can be disabled by going to Settings and typing in "Wireless Emergency Alerts" and then toggeling off "Allow Alerts". I have disabled it on my device just now and will be interested in seeing if it actually stays quiet tomorrow @ 2 whatever pm EST!
