So on my Samsung Focus I had a little plug that went into the headphone jack to avoid dirt getting in the port, sort of like a dust cover. When I got my 920 the other day I put it in the 920's jack and the phone would ring, however, when I answered calls no sound would come out of the ear piece. Drove me nuts until I figured it was the plug and took it out. Works fine now. Anyway, I'm asking if anyone else might use a headphone jack dust plug on their 920 and not have any issues? I thought it was a little weird that my Focus wouldn't have any issues at all but my 920 does with it in.
