I've had my Razr since December, and ever since then the headphone jack hasn't been working. I remember back then a Motorola person said it'd be fixed in a software update. But alas, new updates have done nothing and new Razrs running the same software have working headphone jacks. So I contacted Motorola again and they told that rebooting the phone would fix it, but again, that does nothing.
Has this happened to anyone else? If I put any sort of headphone into it, it doesn't recognize that something is plugged in. It simply continues playing sound out loud.
Just to rule it out, get some compressed air and blow/clean the headphone port out. If its still not working it sounds like its time to file a warranty (or insurance, if you have it) claim. You shouldn't have to do anything else to use the headphone jack besides plugging some headphones in.
