This is a defect, right?

Just noticed that there is a rubber piece in my 830's headphone jack. It doesn't affect the function yet, but I am wondering if it could cause problem later.

My 930 has this too. My headphones work fine so I don't think its a problem.

Yeah, it's fine. I haven't had any issues with mines

not a defect

On the inside of the phone, there is a rubber sleeve that you slide the headphones into. What you are seeing is part of that sleeve, slightly misaligned. Ordinarily, it lines up with the hole, so you don't see it. Shouldn't be a problem.
