[ANDROID] Can software launcher cause the phone power button to become unresponsive
I'm not very familiar with how launchers on Android work, but is it possible that a launcher (e.g. Nova Launcher) can interfere with the Android OS (a manufacturer variant) and cause the power button on the phone to become unresponsive? In this case, pressing the power button does not cause any response from the phone even though it is powered on but the screen is off - the phone remains unresponsive for several minutes (i.e. screen stays off). Or is this more likely a hardware defect? Thanks for any leads in advance.
