How To Enable USB Debugging On Android 4.2 Jelly Bean

Yesterday, Google started rolling out Android 4.2 Jelly Bean OTA Update to the GSM/HSPA+ version of Galaxy Nexus and later, factory images were made available to directly update the device to the latest version of Android. While there were many welcome changes in this update, there was one that freaked out Android enthusiasts and developers who upon updating to 4.2 found the ‘Developer Options’ gone from the Settings. Turns out, Google decided to hide them in form of what is debatably a blend of an easter egg, a prank and a feature. Worry not though – we’re here to help you reclaim the developer options on your Android device running 4.2 Jelly Bean.

Developer Options include several features for app developers that help them build and test apps on their devices while controlling them from the PC via ADB. ADB also comes really handy for end users if they want to quickly access and run commands on their device from their computer. From ICS onward, the USB Debugging toggle could be found under ‘Developer Options’ in Settings but upon upgrading to 4.2, we found them missing. After a bit of asking around, we found the way to easily enable them, and here is how it goes:

  1. Go to ‘Settings’ > ‘About phone’.
  2. Repeatedly tap on ‘Build number’ seven times. That’s it!

Upon tapping for the seventh time, you will be informed via an on-screen notification that you are now a developer. That’s it – you can now find Developer Options under settings at the usual place. To enable USB debugging, just go to Developer Options, enable them and then enable ‘Android debugging’. Enjoy!
