To everyone reading this thread, here's what I expect what happened: While carefully cleaning my phone, a very small drop of santizer might have entered the spaces where the volume rockers sit. I expect that it took a while until it vaporized. everyone should take a look at how to properly clean the HTC ONE. I hope that my volume rockers continue to work as they should, I would hate to be without my shiny new HTC ONE and receiving a REFURBISHED ONE after sending it in. Generally, I don't like refurbished stuff. Yeah, call me old-fashioned, but I prefer to know that the stuff I bought has never been touched or tampered with. For now: THANK YOU for baring with me and responding to this thread - I'll be back if volume rockers go crazy again.
