Android users who are running CyanogenMod 10 or CyanogenMod 10.1, and probably many other custom ROMs, looking to clean up their device’s display by getting rid of the notification bar now have an option to achieve that goal. Best of all, the solution ensures the user can still swipe down from the top edge of the screen to get access to their notifications. This feat was accomplished by XDA Developers forum member enryea123 through some tweaks to the SystemUI.apk and framework-res.apk files. According to enryea123, this solution will eliminate the ability to pull down the notification bar from the lockscreen. All of the changes can be undone just by restoring the stock apk files.
The guide that walks you through the process can be accessed on the XDA forums using the source link below.
