iPhone 4S putting speaker automatically on.

Ok, so here is something new. There have been many times when I answer calls, while I was browsing, emailing or anything else or just when the phone was in standby, and when I pick up the call the speaker comes up automatically.

Several times has it happened to me. Anyone else?

Yup. This has been happening to me too - several times accidentally had answer phone messages play at full volume to full train carriage! And been unable to de-select Speaker.

Separately, I also keep finding that I make calls and there is no sound in the speaker at all - although caller at other end can hear me.
