I am sure you all did this, but just in case - if you go to a protest; turn off your location services. Better to not bring your phone at all and use a cheap disposable or something...
At this point, the idiots at the capitol are mainly getting arrested because they had their location services on lmao.
Edit. I’m being told that my boomer tier understanding of phones is problematic. Read below plz.
The "WiFi Off" switch on iPhones was changed so that it "disconnects from nearby WiFi hotspots until tomorrow". The WiFi option in settings supposedly turns WiFi off completely, but I'm not sure about that either.
I think there are some exceptions to airplane mode, too.
