Hey there! A few hours ago I posted about a bug I have with my phone. (http://xiaomi.eu/community/threads/phone-keeps-pressing-back-button-ghost-touch.23035/) Even when I'm doing nothing, my back button keeps activating. It seems to be broken. I have tried everything but nothing seems to work. So I have searched around even more on the forums (and google) for a solution and found how to enable the android soft-keys by editing build.prop When I disable the buttons in the miui toggles the problem is fixed, but the soft-keys don't work either. Does anyone know what file I need to edit to disable my hardware keys but keep my soft-keys working? I have found information for other phones, telling me to go to "root/system/usr/keylayout" and edit files there. This is where I get stuck. Does anyone know? Thanks!
