It allows you to enable or disable the shutter sound from the option menu in the camera application. You can also use Flash to take pictures at low battery.
Lock Screen Features:
It comes with the Auto lock zone under the lock screen and also allows you to add lock-screen shortcuts from 3 to 5.

4 way reboot menu:
With the help of 4 way reboot menu you can Reboot, Hot Reboot, Download Mode Boot and Recovery Mode Boot in single tap.
Icon Size Reduced:
The default stock ROM on the Samsung Galaxy Grand Duos comes with large icons, and if we speak true then those large icons make it look very ugly. But by using the Gennxt ROM you can have small TWLauncher Icons.
Stock ROM come with lots of Bloatware (unnecessary applications like Google plus, ChatOn, Samsung Apps and etc). But after flashing Gennxt ROM all unnecessary applications will be gone.
