Since some time my iPhone starts often playing music "on its own" when I end a phone call, and I can not find the pattern behind it. I just end a call - and often immediately after that the one and only album that I have on my iPhone starts playing. I never had this until some months ago. I almost never use my iPhone for listening to music. Whenever this is happening I was not listening to music when or before the call started. Can somebody tell me what I might be doing here that causes this behavior, or how else I can prevent this? Thanks.
