I fixed my brother's Note for him, except for a couple things. I replaced the USB port and I'm replacing the LCD later today. My only issue is, one of the three buttons I mentioned in the title is sticking, and it won't stop. Phone just booted for the first time since last night, after flicking the back for a good 10 minutes. I need a way to disable the three physical keys, while leaving the ones at the bottom active. I looked all over Google and can't find anything.
