could be, however, it isnt only for the power button, when the screen is off and a call is coming, it needs a few seconds for the screen to turn on, after the call is done, the system is all choppy and laggy. Turning the screen off after that is also nearly impossible, due to power button malfunction. I went back to stock for now and I'll see if the lag is gone, if it isnt, then its probably a hardware issue.
yeah, I'm on stock 4.1.2 and the issue isnt gone.
