I got a shiny new bluetooth keyboard for use with my Android phone. The right shift button actually launches the browser instead of acting like a shift button, which is very inconvenient, so I edited /system/usr/keylayout/Generic.kl and /system/usr/keylayout/qwerty.kl to change the mapping. I have a little app that simply displays the information from keystrokes, and it now reports that the keyCode is KEYCODE_UNKNOWN for every key I press. The keyboard doesn't work at all now. Can someone point me to an answer or have some advice for me? Thanks in advance. p.s. Samsung Infuse 4G (SGH-I997). CyanogenMod. Android 4.1.2. No carrier.
