don't know android, but ios does a lot of unspecified things during 911.

For example I have location services turned off, but a picture I took while on hold with 911 showed up in my camera roll with full location information. I suspect every app gets full precise location information during 911 (which sort of makes sense in a life-or-death situation)

I wouldn't be surprised if other stuff is affected, like networking/vpn, microphone, etc
