iPhone 5, the volume 'up' button actually decreases sound

Hello,

I just recently started to notice that when I press the up volume rocker on my phone, it actually decreases the sound. I was wondering if it's a hardware or software issue. Would this be something alarming enough to bring the phone to Apple support?

Before you take it to Apple try a DFU restore.
