Blur the Lock Screen on Your Samsung Galaxy S Advance
Being forced to look at a lock screen for the umpteenth time everyday can wear down someone’s liking towards said lock screen setup. So what does one do? You switch things up a bit—maybe a custom lock screen, or customizing it with mods, or even simply a new wallpaper. If however, you own a Samsung Galaxy S Advance, are looking for something different, and up for a challenge, why not give XDA Senior Member BOOTMGR’s Lock screen Blur Effect a go?
Inspired by the GravityBox Xposed Module, the tutorial is written specifically for devices running Android 4.1.2 Jelly Bean. It is compatible with all lock screens, including AOSP, pattern lock, and the default Samsung lock screen. The mod, however, has only been tested by BOOTMGR and confirmed working on TouchWiz firmware, with no guarantee for users running other ROMs.
The process requires you to have android.policy.jar, APKtool, and Notepad++ at your side, and consists of decompiling android.policy.jar, adding, removing and changing code and files with those provided, and recompiling it. Once it’s all done and installed on your Galaxy S Advance, the mod will take a screenshot of your current screen when you’re locking your device, apply a blur effect, and set it as the lock screen wallpaper. Pretty neat.
