This is weird.
I have deleted every "WAKE" entry regarding the "HOME" button from every file inside the /system/usr/keylayout folder, rebooted numerous times and yet, my home button still wakes up my screen.
I even tried to delete the "HOME" word altogether in GPIO-Keys and Sec-Keys, leaving only the "172" part and yet the home button still wakes up the screen.
My model is I747M (Canadian) on 4.4.2 with touchwiz stock rom, rooted and Next Launcher 3D.
Anybody got a clue ?
