I have the old Nexus 7 with stock 4.4.2, and I want to enable developer settings.
I have found many references to Settings -> About (Tablet) -> And click 7 times on build number - but that simply does not work. I have tried tapping it 1 million times and nothing happens. If I tap "Android Version 4.4.2" in the same menu, I get the whole spinning K, kitkat, easter-egg game etc.
What am I missing? How do I enable developer settings?
