Mostly people like to purchase smartphones due their hidden features like most of you know about some dialer codes on your smartphones that allow you to access some hidden features of your smartphone. A recognized developer over XDA E:V:A did the same with his Samsung Galaxy S3.
He got many hidden features from the Galaxy S3, like you can get access to the service menu on your Galaxy S3 by typing *#*#197328640#*#* . He provided some codes, he didn’t only provide the codes but also tell the users that how they can find new codes to access new features themselves. Before you get started, first you need to download the appropriate apps:
Get jd-gui (Often crashes) Get jad (doesn’t crash, but is cmdline based) Get sgs2toext4 (and here) Get Disk Internals Linux Reader Get a disk image with deodexed Apps.
He made a complete that instructs you how you can easily get new codes and also get new hacks, you can’t say that it’s development but you can say that it’s really something interesting that you should do. So if you want to learn something from E:V:A, head over to the original thread of XDA here. The developer also provided number of reference for you.
