HTC One M7 - power button keeps hanging up phone calls

[AC Question]

I've noticed lately that pressing the power button on my device hangs up my phone calls. Which is a bit annoying as before, pressing the power button during calls used to merely lock my screen - which I prefer. I think this changed with a setting but I'm having trouble getting it revert back to my old setting. Any insights?

Welcome to Android Central! Go to Settings>Accessibility, and make sure "Power button ends call" is unchecked.
