Just got a Samsung Galaxy S3 mini with Android 4.1.1 factory installed. The phone is not locked to any carrier. My problem is that I can not for the life of me find the setting to turn on the haptic feedback, neither for the keyboard nor other touch events (such as the menu button, etc.). I've looked through the settings menus several times without finding anything.
The actual vibration hardware is working, because if I go to Settings -> Sound -> Device Vibration it vibrates.
The only other mention of this issue I've found was one unanswered thread on the Samsung Galaxy Forums.
This is the kind of thing that makes me wonder if Google (and others) are actually trying to make things worse with every update. My HTC Nexus One running Android 2.3.6 never had any oddities like this. Only problem with that old phone is it's limited internal memory.
