问题
Sorry for stupid question, but can I listening touch events from android phone, while display is off? Or touch system works only when display is ON..?
回答1:
Only when the display is on since the touchscreen needs power to detect touches. However, there is some research to re-register the sensors when the screen is off, so maybe you'll have some luck if you follow that route.
