Reply All should remove your own email address from CC recipients line.
I received an email on which I was CC'd. When I hit reply all, I noticed that my email was still in the CC recipients line. After I hit send, I received what looked like duplicate emails. One email was from my sent box, and the other email was the email I CC'd myself. Tested in beta on Samsung Galaxy S3.
Thanks for your feedback.
I’ve added this to our internal bug tracker.
It would be nice if you also come and join us in the Beta Community and make posts there, it’s easier than here :)

Currently, a reply-to-all will also send an email to me. I'm using Exchange.
