If you have upgraded your android phone to Android 4.2 or higher, you would be surprised to see that your phone wont have the Developer options in the settings. The same happened with me when I upgraded my Galaxy S3 to Android 4.2. After the upgrade I found out the developer options was missing and since I had to enable USB debugging, I was desperately searched the internet for a solution.
Fortunately after searching through the internet for a few minutes, I finally found out that by default the developer options was hidden on android 4.2. This is same for all android phones running android 4.2 and higher, irrespective of the manufacturers.
I don’t know the reason behind Google hiding the developer options, but if you want to enable the developer options on your android device running android 4.2 or higher, the following steps should help you out.
