My phone rebooted and I lost all custom settings (like text size, custom ringtone etc.), while retaining other apps data. This was simple to repair
Problem is, since then my "Home" button doesn't execute launcher anymore. If I long-press, it shows tasks list, so the button is working, but short press does.. nothing.
I installed Home2 Shortcut - doesn't work either.
Cleared TouchWiz settings - no change
Cleared "Application preferences" - no change
Installed Nova Launcher - works fine, but won't return to home screen on "Home" press.
I guess some simple setting got corrupted, but I've no idea where to look for that. I'd rather not reflash the phone just because of this one button, but it's quite nice to be able to go to Home screen
