Most of the time whenever you would like to flash or upgrade your Android device via flash tool or whenever you want to Root your android device you need to enable USB debugging mode in order to connect and communicate with your Android device. This mode not only useful for connectivity but helps in sending command code to your Android device via Odin. By default the USB debugging mode is disabled for any brand new device to avoid unintentional modifications on your device. But you need to enable debugging option manually for your Android development process. For different Android versions there will be different configurations to turn the USB debugging mode.

Features of Developer Options

The “Developer Options” feature is indispensable to Android developers, hackers and enthusiasts as a means to quickly access and control their device from the PC. Even if you are an average user and wish to root, install a ROM or mod on your Android device, you must turn on USB Debugging mode on your phone or tablet. And you’ll not be able to do it unless you enable Developer Options on your device first.

Among the most useful features that are  found under Developer Options are as follows:

  • Enable debugging over USB.
  • Quickly capture bug reports onto the device.
  • Show CPU usage on screen.
  • Draw debugging information on screen such as layout bounds, updates on GPU views and hardware layers, and other information.
  • Many other options to simulate app stresses or enable debugging options.

The “Developer Options” has always been visible by default in all previous versions of Android. On

Developer Options on Gingerbread (Android 2.3):

Settings> Applications> Development> USB Debugging

Developer Options on ICS (Android 4.0):

Settings> Developer Options> USB Debugging

Developer Options on JB (Android 4.1):

Settings> Developer Options> USB Debugging

If you have recently upgraded your device to Android 4.2 Jelly Bean or have bought a new device with 4.2 or higher pre-installed, do not be surprised if you find the  ”Developer Options” missing.

How to Enable Developers Options on Android 4.2

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 S4, Note 8.0, Tab 3  or any other Galaxy device with Android 4.2, open Settings> More tab> About and tap it.
  3. If you have Galaxy Note 3 or any Galaxy device with Android 4.3, go to Galaxy Note 3 from 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”.
  6. Return to the main Settings menu and now you’ll be able to see Developer Options.
  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.

Enable USB Debugging on HTC One:

If you own a HTC One or any other HTC phone with Android 4.2.2 Jelly Bean, 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.

Hiding Developer Options on Android:

Once activated, the Developer Options on devices with Android 4.2/4.3 or above remain visible. You will not find a single option that lets you revert back to the state when it was hidden. However, there is still a way to hide Developer Options on Android device. To do this, you will have to boot your device into Recovery Mode and perform a “data/factory reset”.
