Android phones from OnePlus, Samsung, others reportedly reboot when dialing 911

As far as I've seen, users in comments report seeing similar issues on OnePlus 5, Nexus 6P, Samsung Galaxy S7 Edge, slightly different behavior on MotoG5+.

There's a second thread specific to the MotoG5+ report [https://www.reddit.com/r/Android/comments/660jsl/crosspost_m...]

EDIT: apparently this is related to their non-stock dialers or something. People in /r/oneplus are saying to install and use the stock android dialer
