Samsung Jet S8003 Hidden Menu

Hey guys....found a secret menu code for Samsung Jet S8003, thought of sharing...
Just tap in the following in the keypad *#6984125*# no need to press dial key..
Then a pop up menu will appear . You can know your phones information in this.
If you want to configure your phone, like increase the earphone volume(Which i think is too low), speaker volume or use the front camera or wifi just go to the option 4. Internals .
The phone will ask for a master key. Just type in *#9072641*# and press confirm..
a new menu will pop up....do whatever you want in that...
If any critical value changes ,then you can do a master reset..

Or youcan try this one
*#5239870*#
internals master key
*#7092463*#


The method above is obtained from internet sources, try only at your own risk.
