Q: iPhone 6 has no speaker sound only Headphone when adjusting sound level. How do I get Volume setting vice Headphone setting

Well, for some very strange reason, after doing everything in the book especially the reboot sequence of holding down the home button and the on/off button for 10Seconds, after giving up, moments later, wife picked it up and the sound and everything dealing with sound worked perfectly. She insists it was her prayer.  Who am I to argue.  It's up as new.
