[Q] Can you only use the power button to unlock the screen? topic

Can anyone unlock the phone using home button ?
it only works with the power button for me. The home button works when the screen is on but not when , the screen is turned off the phone flashes for brief second then screen goes off, i noticed this before i downgraded and after it has always been like this, its like I am double tapping it when I am not . I get the same response if i double tap the power button
