Why is my iPhone 6 speaker always on
How can I get my speaker to NOT come on. It has started coming on no matter whether I make a call or receive a call.
iPhone 6, iOS 9.3.1
Force restart the phone
Restart your iPhone, iPad, or iPod touch - Apple Support
Also gently blow into the headphone jack to see if there is any lint etc in there - if that does not work
Make a "Genius" appointment at an Apple Store, or go to another authorized service provider.
