The developer options lie at the core of Android development and so they cannot be removed as long as Android is an open source environment. The only change Android 4.2 brings in connection to these useful options is that now they are hidden by default and you will have to make it available by doing some finger exercise.
- Open Settings> About on your Android phone or tablet.
- If you have a Samsung Galaxy S3, S4, Note 8.0, Tab 3 or any other Galaxy device with Android 4.2 or Android 4.3, open Settings> More/General tab> About and tap it.
- If you have Galaxy Note 2 or Note 3 or any Galaxy device with Android 4.3, go to Settings> General> About and tap the Build version 7 times.
- Now scroll to Build number and tap it 7 times.
- After tapping the Build Number 7 times, you will see a message “You are now a developer!” If you have a Galaxy S4 or any other Samsung Galaxy device with Android 4.2, the message reads as follows- “Developer mode has been enabled”.
- Return to the main Settings menu and now you’ll be able to see Developer Options.
- Tap on Developer options and mark the box in front of USB Debugging to enable it.
- To disable USB Debugging mode later, you can uncheck the box before the option
- To enable Developer Options, go to Settings> Developer options and tap on the ON/OFF slider on the top of the page.
