Nexus 4 Power Button Weirdness...

Is anyone else experiencing this with their Nexus 4 devices? I previously had something exactly similar with my old GNex, but this never happened on my current Nexus 4 until after a month of use (I got it a month ago).

Sometimes, pressing the power button from the screen-off state won't always turn on the device. I'll have to press it twice or even three times for the screen to turn on. Sometimes, it turns on, but then turns back off right away (as if I pressed it twice).

From the screen-on state, something similar happens when I press the power button: the screen turns off then back on, as if I pressed it twice again.

I googled around and saw others have similar issues... but should I be worried? The last thing I want is the button I use the most stop working...
