iPhone problems, anser calling, calendar etc

Hi there. I have a Iphone 6 with Vo and two problems. When I will anser a incoming call, then double tapping with two fingers, then Music start to play at same time. I wonder why? It is not of my own Music either. A very frustrated problem. When he try to call again, then I swipe to anser button and single double tap then it works. But the gesture with two fingers double tap dont work cuz of the Music plays. Where comes it from ? Another problem is a bug in iphone's calendar. I can not add a activity there. I'm Writing title, Place, time etc and finished with save but nothing object looks. It is a bug? I have to ouse my calendar!!!

Hi. I had the calling thing

Hi. I had the calling thing happen when I called a friend of mine. She calls me, and music played when I answered the call with the two finger tap command. Don't use this when answering a call, swipe to the answer button, and single finger double tap. With the calendar issue, just use siri to set up appointments. It's the fastest way to do this.

Double tap plays music

I'm using an iPhone 5 and ios 8.1.2 and I'm having the same problem, but not just when answering calls. When I use the Dictate function in Messages, I start dictation with a single-finger double-tap. However, often when trying to end dictation with the two-finger double-tap, music begins to play. It is always music from my iTunes acct. It has also happened in Kindle, and others.

Sometimes I also manage to turn off speech. It actually says, "Speech Off" - not VO off.

I did notice when I recieve a

I did notice when I recieve a call VO will put it's focus on the answer button so all I have to do is a single finger double tap. If I double tap on the screen it will play my music.
