Hi
I have a galaxy s3 with cm11 and boeffla kernel. Today, out of nowhere, my home button and menu button started acting weird. I have the home button setted to sleep my phone on long press and wake it up when the screen is off and do nothing on double press . The menu is set to open the recent apps. It has always worked this way till today.
When I press the home button inside an app it won't return to the home but it still wakes the phone when the screen is off. Also the menu won't open the recent apps and it doesn't vibrate either. The back button still works but does not vibrate. I used gravity box to activate the navigation bar and the home button doesn't work on the navigation bar either.
I tried installing upgrating my firmware to the latest nightly, wipe cache and dalvik but no luck.
