When I enable the mobile data on my Samsung S Duos, it enabled and disabled all settings automatically, even the mobile data is getting turned off. I am unable to use any application on that time, kindly help me with this.
This behavior is encountered whenever there is a problem with the APN section. I recommend reconfiguring the phone with the APNs from your local carrier. Re-configure the settings for the APN, then reboot the phone and it should work accordingly. I myself encountered a similar problem when the Mobile data turned itself off whenever I activated it.
