I've noticed that even though my screen is locked with a PIN, the quick button and volume buttons still bring up apps (the Quick Memo+ & Camera apps). If I've locked my device to prevent others from using it, why are they allowed to leave me notes, or more concerningly, why can they take pictures and videos with my phone?

I understand how others would find quick access to these features useful, but shouldn't I be able to turn that functionality off so that others can't leave strange photos or videos on my device? I tried changing the default app for the quick button, but when the screen is locked, it always starts up Quick Memo+ regardless of what value I set for that button (when the phone is unlocked, it opens the app I setup).
