developer options disappear from settings

Question

After upgrade to Android Jelly Bean 4.2 I couldn't find developer options in the settings. What happen to this setting? Where can I find it now?

Answer 1

I found that its hidden in the settings menu to improve user experience. You can activate it at any time by tapping 7 times on Settings > About phone > Build number

from official android documentation:

On devices running Android 4.2, developer options are hidden by default, helping to create a better experience for users. You can reveal the developer options at any time by tapping 7 times on Settings > About phone > Build number on any compatible Android device.

Answer 2

On most devices running Android 3.2 or older, you can find the option under '

Settings > Applications > Development.

On Android 4.0 and newer, it's in

Settings > Developer options.

Note: On Android 4.2 and newer, Developer options is hidden by default. To make it available, go to

Settings > About phone and tap Build number seven (7) times. 

Return to the previous screen to find Developer options.
