With the recent update of the Android OS Jelly Bean to 4.2, the developer settings were nowhere to be found.
It turns out that this stupid move was deliberate and the developer settings screen is now hidden,
To get it back you need to do a kind of easter-egg hack - you go to "Settings" > "About phone" and literally tap the "Build number" 7 (seven!!) times, to get the developer settings back.
Way to go Google,
I guess you think all your users are stupid.
Thanks for that.
Try tapping the other things on the list. Don't faint from the excitement.
