On Android™ version 4.2 and higher, the Developer options screen is hidden by default. To unhide the Developer options, press Menu Menu key > Settings Settings Shortcut > More Settings More Tab Icon > About Device Settings About Icon. Scroll down to Build number and touch it seven (7) times. The menu option will then appear under Settings Settings Shortcut > More Settings More Tab Icon > Developer options Settings Developer Icon.
