I have an samsung SGH-M620 and can't install java software on it because :
1- it need JAD file that many software don't have it
2- when a software have jad file or I creat it by JADMaker, and want to install it give error" Java Error. content size too large" (I also can't install mobile banking software)
3- also I must enter unlock code *#9998*4678255# to install a software. I can't even install opera mini.
can I resolve this problem or this phone doesn't support software ?
