How to Enable Developer Options and USB Debugging on Android Cellphone?

[Andy]

In fact, 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.

1. Open Settings> About on your Android phone or tablet.
2. 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.
3. 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.
4. Now scroll to Build number and tap it 7 times.
5. 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”.

7. Tap on Developer options and mark the box in front of USB Debugging to enable it.
8. To disable USB Debugging mode later, you can uncheck the box before the option
9. To enable Developer Options, go to Settings> Developer options and tap on the ON/OFF slider on the top of the page.

If you own a HTC One, HTC One Max, HTC One M8 or any other HTC phone with Android 4.2 or Android 4.4, here is how you can turn on the Developer Options on your device:

1. Open Settings> About> Software Information> More.
2. Then tap “Build number” seven times to enable Developer options. Finally you will see “You are now a developer!” message on the screen.
3. Go back to Settings menu and now you’ll be able to see “Developer options” there.

4. Tap it and turn on USB Debugging from the menu on the next screen.
It is not obvious why Google decided to hide the “Developer options” on the latest version of Android. I guess they might have done it as a warning for noobs but whatever the reason might be, you can easily turn on the Developer Options and enable USB Debugging mode in a fun way using the above method.
