This is my 6th day with my 6 plus and from day one, I have been experiencing issues with my speaker. It sounds like it has a blown speaker. There is no other way to describe it. It is not as loud as my 5s and it comes through as muffled and choppy "you can say". I guess I'll be making a genius appointement for this. Frustrating ! Is anyone else experiencing similar speaker issues with their 6 plus ?
