OnePlus 5 user dials 911, the phone reboots (Update: not just OnePlus)
While we are used to the fact that said number would always, always be available to us, a OnePlus 5 user has reported that this is not the case for him. In a post on Reddit, he said that he tried to call 911 when he spotted a house fire in Seattle and the phone rebooted. This has happened two times during the incident, but the user also reports that he was able to replicate the issue and also got it on video.
Browsing through the comments shows other people claiming that the same happens when dialing 999 or 112 (the 911 of Europe). However, some claim that they have been able to get a 911 call through successfully in the recent past, so it might just be an isolated issue.
OnePlus has issued an official statement on the matter, which reads:
While knowing that you can connect to 911 when needed is certainly a must, we would advise against randomly going off and dialing the emergency hotline. If you insist on checking if your phone is fine, see if you can call your police department's non-emergency phone, explain the issue, and ask when it would be a good time for them for a test call. Either that or wait for OnePlus to post an update on the matter, or ask support if it's fixed after some time.
