I can't find the developer options in my tablet running Android 4.0.3

Head into the Settings menu. Samsung's done things a little differently and changed the way the settings menu looks, so you'll need to hit the "More" tab, and then get into the Software information.
Look for "About device" at the bottom. Tap it.
Hop on down to the build number, and tap it seven times. One. Two. Three. Four. Five. Six. You'll get a little prompt saying you're about to unlock the developer settings. Hit that button one final time -- seven! -- and they're unlocked.


Have you tried this? Its really a bit tricky.
