Learn to Add Jelly Bean Lock Screen atop TouchWiz
There is no better feeling than making your own device, truly your own. The way we do this at XDA is by tweaking the daylights out of it. However, there is more to life than simply installing APKs or flashing zip files through recovery. There is a far more rewarding process in tweaking your device, and that comes from the joy of doing things oneself. If not for the eye candy pleasure provided, it is great for the sake of learning how to do something new. But, wait! Where to start? Android files are numerous, large, and require a certain skill set to master and modify, right? Well, yes, but luckily we have people like XDA Recognized Contributor tdunham who can definitely lend a hand during the learning process.
In this particular instance, the dev shared a way to enable the AOSP lockscreen on the Epic 4G Touch (running Jelly Bean leaks). Because most manufacturers like putting their own flavor on their devices, it is highly unlikely (with a few exceptions) that you will purchase a device that comes with a stock Android lock screen, and Samsung is no exception. The guide that the dev has posted will allow you to see and understand what code is used to enable the missing, infamous AOSP lockscreen to the device’s already wide arsenal of eye pleasing effects. This is particularly useful if you like the stock ROM and really don’t feel like flashing to AOSP ROMs. And again, the end result is that you get the look that you want and leave a more knowledgeable individual at the end of the process.
What are you waiting for? Get the tools needed to decompile the required files (namely android.policy.jar and secsettings.apk), put on a fresh carafe on your Mr. Coffee machine, and let your hungry curiosity take over. Remember that you will need certain tools to do this (other than coffee), so make sure that you are ready. Please share your experiences and any tricks you may have learned along the way.
