Samsung Duos GT C-3222 Secrete code

Hello Friends,

You can play around with *#52828378# code , I have tested it on my duos , and working fine with me.
I wanted to install java application on my duos , for that you need to get in :
OTA test basic >> set Maximum JAR size (kb)" between 500 to 650 , and you will be able to install small java applications on your duos , upto 650 to 700 Kb

Best Regards,
Girish...
