Samsung recently released Android 4.2.2 update for the very famous Galaxy Grand Duos. I had my hands on this new OS looking for some new features and option. It did bring some small but good changes in the user interface. It also has a new way of representing the settings in a tabbed way. Also if you slide down notification centre with two fingers touching the screen, it will list all the quick access button for most of the settings like Smart Screen Mode, Wi-Fi, Bluetooth and others.

One thing which i found confusing was the Developer option.. I didn’t see it even after looking in the settings and all possible option in the settings menu. Now here is a little trick to enable Developer Option in the new Firmware. In the old firmware 4.1.2 it was present by default but in the new firmware you will need to enable developer option before you can use it options.
How to Enable Developer Option in Galaxy Grand Duos.
First head towards the settings. It is really easy.. though was tricky for me to find a way to enable developer option in the beginning. Once you are in the setting options in the new 4.2.2 Android version, select the More Tab and then navigate to the bottom most option About Device . Tap on that.
It will show you the screen shot given below. Navigate to the BottomMost option which says Build Number. Tap on that continuously for 6-9 times.
After you do this the developer option will automatically be enabled for you and from now on you can find the developer option in the settings menu.
The Developer Option comes with many option like USB debugging and all sorts of option. We suggest you to use any of them only when you know what are you doing. These are not meant for general use and are only used for the testing and development of apps and firmware.
