Strange thumb wheel issue on M-P

Hi guys, I bought an M-P last April, and I have been using it ever since, no problem at all. But last Monday, when I was out shooting photos with it, I noticed one strange thing, after I captured a photo, I pressed the "Play" Button to view it, however, that photo was automatically zoomed in, as if I had moved the thumb wheel, but I didn't do that obviously. I don't remember if I ever put my thumb on the thumb wheel, but I was pretty sure I didn't move it. And it occurred only once, I have done some shooting the following day too, but nothing happened.

 

So have you guys encountered the same issue? What could be the reason behind it? I sweater often when I'm holding the camera, so could the sweater somehow got into the thumb wheel and caused it to automatically move? Or was is it some CMOS or systematic issue?

Mr. Obvious checking in. You have removed the battery and replaced with a fresh battery, I trust.

Which means you are not 100% sure. Only take note of such occurrences if they repeat themselves.
