iphone 6 missing dictation mic with ios 11.1.2
I updated my iphone 6 last night to the most current iOS (iOS 11.1.2). This morning I noticed in the text app there is no longer a dictation mic to type out my text for me. I went into settings>general>keyboard> to 'Enable Dictation' and the option is not there, on my iPhone 6, however it is still available on my iPhone 7 plus; that still has iOS 11.1.1. Has this option been removed or is this a glitch? I'm afraid to update my 7 plus to the most current iOS.
iPhone 6, iOS 11.1, iOs 11.1.2
