There are plenty of options when looking to run a custom ROM on your Android device and one of the most popular, besides CyanogenMod, is Paranoid Android.
Official PA ROMs only support Nexus devices, so if you don’t see your device in the downloads, it’s not supported by the main development team, but there may be a port and you just need to search the forums.
Up until recently, the latest PA ROMs based on Android 4.4 KitKat were primarily a stock experience, but today an update was released, PA 4.1 beta, bringing one of the ROM’s killer “flagship” features, PIE controls, its stock navigation replacement.
According to PA, PIE is “a simple, straight-forward replacement of the navigation bar that optimizes the screen space available to the user.”
PIE is basically a fully-customizable replacement for the on-screen navigation buttons and stays hidden off-screen, only seen with a predefined gesture that can come from any of the four sides of the device.
Via Google+, the PA development team said that it faced some problems with the immersive mode introduced in KitKat, and has now released a redesigned version to match the KitKat design philosophy. Instead of porting the feature to its KitKat ROMs, PA completely redesigned the feature for the new version of Android.
PIE controls are now fully-integrated into the core UX with the introduction of “on-the-spot preferences,” so PA users no longer need to sort through endless settings.
Additionally, it gives users status information at a glance when your status bar is hidden in immersive mode, plus the stock Google Now swipe up gesture is now integrated.
If you’ve never tried out Paranoid Android before, be sure to check out 4.1 beta on your rooted, unlocked device, which is now available for the Nexus 7 2013 (Wi-Fi and 4G), Nexus 7 2012 (Wi-Fi and 3G), Nexus 5, Nexus 4, Nexus 10 and the Galaxy Nexus (GSM, Sprint and Verizon). Be sure to grab the latest Gapps as well.
