How to Enable USB Debugging & Developer Options in Android 4.2 Jelly Bean

enable usb debugging developer options in android 4.2 Jelly Bean

The USB Debugging and Developer Options are hidden in latest Android 4.2 Jelly Bean. If we want to use that options, manually activate it. Google has rolled out latest Jelly Bean OTA update for their nexus mobiles. After the updating process, the developer option is not there in settings. Here is the guide to enable USB debugging on Android 4.2 Jelly Bean running mobiles and tablets.

Developer Options have many features for app developer to test an app on their device from PC via ADB. After enabling the debugging mode only, access the mobile from PC. ADB is used for users if they want to quickly access and run commands on their device from their PC or Laptop. In gingerbread it is placed in Settings> Applications > Development > USB Debugging. And ICS it is placed in Settings > Developer Options > USB Debugging. But, after upgrading it to 4.2 it is missing. After a long time to search around, we found the way how to activate it.

    Wow, Great Find. Without this, I’ll still be lost. Why would google do this (hiding something that is so useful)??

    Hello biggest thank you to you I was tired to find debugging option after update 4.2.2 galaxy grand GT-I9082 for root it. After your help I did it thank you again.

  • Kool Breeze

    Is their a way to force usb debugging on I have a galaxy discover something happend and my settings and all apps are gone all that is currently working is email I tried to install the settings app from my duplicate phone and the phone says cant install unless directly from market.The only thing I can think of is an app that would force debugging on run from an attachment in my email.I tried backing up the rom from the duplicate phone and tried to install I get an authentication error.In any case it pretty much a brick at this points unless I can find a way to get a file manager installed or the setting if I could force usb debugging on then I could do full backup from my other phone and restore it with ease any suggestions would be great.
