Power Button Responsive but won't power ON or OFF
My power button will wake the phone and sleep the phone but it won't power the phone on or off. When I hold the button down though, it does not bring up "slide to power off" and if the phone is off, it won't turn the phone on.
Is this a defective ribbon cable or logic board? After all, the button does work and is responsive. Volume and vibrate work, didn't check headphone jack.
Is this a good question?
