According to Google, unless you’re a developer, there’s not really much reason you’d mess with the appropriately named Developer Options. Consequently, Google’s hidden it from Settings so that “normal” users will not accidentally mess up their phones, throw a tantrum, break down completely and just sit and cry in the corner of their room, mourning the loss of yet another Android phone.
However, if you enjoy that sort of thing, here’s how to get the Developer Options back. It’s really quite easy; I actually unlocked it by accident since I randomly tap things in the hope of discovering Easter Eggs.
1. Open up Settings and scroll down to About Phone.
2. Start tapping Build Number like a mad man. Eventually you’ll see a countdown and then “No need, you are already a developer.”
3. Go back to Settings and Developer Options should now be unlocked. Try your best not to mess anything up.
