Google has hidden the developer options in Android 4.2 Jelly Bean upwards (Kit Kat, Lollipop and Marshmallow). This is to ensure that regular users of Android devices don’t accidentally enable options that may impact the user experience that are only intended for developers testing apps. Here’s how to enable developer options in 4.2:
- Go to the settings menu, and scroll down to ‘About phone’. Tap it.
- Scroll down to the bottom, where you see ‘Build number’.
- Tap ‘Build number’ seven (7) times. After the third tap, you’ll see a toast notification that says “You are now 4 taps away from being a developer”. Keep on tapping and a toast notification will say “You are now a developer”. You now have the developer options back on the settings menu.
