My iPhone not ringing problem is solved

[Kenji]

I asked at the meeting tonight if anyone else has problems with riingtone after the latest IOS update. 

Turns out it had nothing to do with the update. 

In Settings > Sounds & Haptics my ringtone volume was all the way down and the Change with Buttons switch was off, so the volume buttons had no effect on ringtone volume. 

My phone came off the dash mount while I was driving on the freeway the other night. I think Settings was already open, and in the process of fumbling for the phone while driving and picking it up I musta switched Settings panes and pressed buttons.
