Well I have this bug or annoying problem where I plug in a headphone/headset/earbud/etc. where the One S calls the most recent person you called. It's really annoying as it did this around several times from 11PM to 3AM this week. I have searched google and have found a few threads and complaints about it but no fix. It may be that I am not using a better description in the search. Anyone know about this? Can you help?
